The solution to unblock the disabled registry

2010-08-14T16:59:00.000-07:00

Registry was modified is terrible. I will tell you several solutions to unblock the disabled registry.

1. Import. Reg file (for WINDOWS 9X/2000)

For WIN9X, save the following text. Reg file, double-click and import into the registry:
REGEDIT4;[HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Policies/System]"DisableRegistryTools"=-;
For WIN2000, the same is to create a. Reg file, the same as above, only replace the first line "REGEDIT4" to "Windows Registry Editor Version 5.00".

Special Note: This method is invalid for WINXP.

3, reg command (for WINDOWS XP)

Click [Start] - [run], in the dialog box, type reg delete hkcu / software / microsoft / windows / currentversion / policies / system / v disableregistrytools / f, click OK.

4, using the. Inf file (for all WINDOWS)

Create a text file, change the file extension. Inf, which enter the following:
[Version]
　　Signature="$CHICAGO$"
　　[DefaultInstall]
　　Delreg=Del
　　[Del]
　　HKCU,SOFTWARE/Microsoft/Windows/CurrentVersion/Policies/System,DisableRegistryTools
Then right-click the file, then click [Install].

5, Group Policy (for WINDOWS 2000/XP_PRO)

Click [Start] - [run], in the dialog box, enter "gpedit.msc", click [OK], open the Group Policy, navigate to the [User Configuration] - [Administrative Templates] - [System], double-click the "Disable Register Table editing tools ", choose [not configured] or [disabled], click [OK].

6, using other registry editing tools (for all WINDOWS)

Disable editing the registry in fact can only disable the WINDOWS own Registry Editor Regedit, but not limit the other registry editing tools, more useful registry editing tool are Registry Workshop, Resplendent Registrar, Reg Organizer, etc.. Use these tools to open the registry, find HKEY_CURRENT_USER / Software / Microsoft / Windows / CurrentVersion / Policies / System, delete the value "DisableRegistryTools", ok.

7, use other users name to log and modify (for WINDOWS 2000/XP)

This method is more trouble than just be a reference. For example the current user is not Administrator, log off current user, using the Administrator account to log in, run regedit to open Registry Editor. In Registry Editor, click the HKEY_USERS root key, and select [Load Hive] under [File] menu, open the "C: / Documents and Settings / user name / NTUSER.DAT" file, and then click [ Start] pop-up dialog window, in the [item name] box, enter a name. Under the HKEY_USERS will have a new subkey items just entered, in which to find Software / Microsoft / Windows / CurrentVersion / Policies / System, delete the value "DisableRegistryTools". back to the sub-item just selected, then choose [Unload Hive] under [File] menu.

Sata hard drive can not start

2010-04-15T19:30:00.000-07:00

My motherboard is 865PE motherboard of a brand, recently upgraded a 120GB SATA hard drive. It’s said that the performance and speed of SATA hard drives are better than IDE hard drive, so i want to install the system on SATA hard disk, use it to boot the system. But after connected to computer, i found no matter how sata hard drive will not start the computer, how can I get my computer started from the SATA hard drive?

A: When boot after installed SATA hard disk, press "DEL" key to enter the BIOS. In the BIOS, Integrated Peripherals menu, the "Onboard H / W Serial ATA" item is set to "enable", then enter the Advanced BIOS features menu, the "SATA / RAID / SCSI boot order" function is replaced with "SATA", the final set the "First boot device" to "SATA", it will be ok.hard drive repair.

How to optimize SATA hard drive

2010-04-15T19:20:00.000-07:00

Recently I purchased a Seagate Barracuda 7200.9 160GB hard drive, it’t the optimization of the SATA hard drives and PATA hard drives as the same before?

A: First of all, SATA hard drive can be optimized the same as the traditional hard disk, for example, defragment, etc.. In addition, the correct motherboard driver installation is also very important. After you install a good driver, and in some chipset platform requires the correct settings, open the DMA mode, the problem usually lies in the VIA chipset, etc., Intel's is rarely the case. There are a number of chipset vendors for the convenience of users, also offers a special hard disk speed up software, such as: Intel's IAA (Intel Application Accelerator), software installation, the program will automatically use the physical characteristics of the best hard drive transmission mode to achieve the purpose of optimizing the hard disk.

What to do my SATA drives can not be recognized

2010-04-10T01:57:00.000-07:00

My computer configuration is: AMD K8 3000 +, ASUS K8N-VM, GeIL DDR400 512MB, Seagate Barracuda SATA 160 (ST3160812AS), the operating system is WindowsXP SP2, but I found the system hard drive was recognized as a portable hard disk and the system the taskbar has a "Safely Remove Hardware" sign, will affect the normal use? read and write speed also is very slow, the sata hard drive can not be recognized, what should I do?

In general, SATA hard drive is recognized as a portable external hard drives in WindowsXP is normal, and will not affect its normal use, if the mouse point system tray "Safely Remove Hardware" sign, will see your hard disk drives, if you point "stop" button at the same time, and it will not work, so do not worry misuse affect the use, if your hard disk read and write slowly, be sure to have installed the speed drive of SATA interface.

How to partition 250g hard drive

2010-04-09T02:34:00.000-07:00

I found partition tools such as FDISK and DM GHOST software tools seems not support the new 250GB SATA hard drive in the application. How to partition the 250g hard drive?

SATA hard disk is to support these tools software. The such problems of use of partition software have occurred on the South Bridge ICH5 motherboard, because they are based on the DOS platform, you must use compatibility mode (Compatible Mode), when set to enhanced mode (Enhanced Mode) will trigger the failure that the software can not use. partition hard drive

In addition, the use of 160GB and larger capacity SATA drives, due to this type of partition software FDISK (Windows 98 version included) and DM introduced earlier, it can not well support more than 137GB hard drive 48bit addressing, it may lead to inexplicable failures,
So the most secure way is to install SP1 or SP2 of Windows XP (or Windows 2000 SP4), before the installation of the system, only hours only spend to install a partition. after install the system, modify the registry, through "Start → Run", type regedt32 command, open the Registry Editor, Create a new subkey under the key [HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Atapi \ Parameters], named as EnableBigLba, type is DWORD, value is 1. Then use the "Disk Management" feature in the "Start → Control Panel → Administrative Tools → Computer Management" to create the rest of the district.hard drive repair

What to do when hard disk have bad sectors

2010-04-09T00:00:00.000-07:00

I district my 80GB hard drive into C, D, E, F 4 partitions, the recent when boot, the system self-test and prompt "Warning: Immediately back-up your date and replace your hard disk drive, a failure may be imminent". Sometimes i press the Enter key to start normally, there have been crash phenomenon that unable to enter the system. Many times I have to format the partition and reinstall the system, but still have the failures, how to solve it?

When computer self test and prompt the above information that means "immediately back up the data stored in the hard drive and replace your computer's hard drive, a failure will soon occur." At this point you should do the following:
(1) use the disk repair software (such as PQMagic) check the hard disk under DOS mode, if the data damaged (such as navigation records are missing) and other soft fault, you can repair it directly, if hard disk have bad sectors such as hardware failure, you can use hard disk repair software to repair bad sectors or temporarily isolated it.
(2) then re-partition and format the hard drive(format hard drive) and reinstall the operating system operation.
(3) If the disk has bad sectors, re-partition approach to isolate bad sectors are only temporary treatment measures, you should send your hard drive to the professional hard disk maintenance department to repair.(Prior to this, please backup of important data to prevent loss).hard drive repair

Hard disk repair soft errors-2

2009-12-21T18:38:00.000-08:00

(2) repair the hard disk DOS boot record
Repair method can refer to the above example, to select the DOS version and the hard disk the same type of computer is suitable.
① to start a normal computer, and drive home an A blank, formatted disk, type the following statement sequence:
C> DEBUG
-L 100 2 01
-W 100 0 501
At this point, has made well-DOS boot disk in the floppy disk blocks and write the logic 50H sector.
② The DOS floppy disk boot failure of the computer, after entering DEBUG into the floppy disk drive A, type the statement in the DEBUG state sequence:
-L 100 0 501
-W 100 2 01
At this point, the hard disk DOS boot record repair is completed

(3) repair system files

System, system boot files are an important part of the module, if damaged or wrongly IBMBIO.COM or IBMDOS.COM deleted, DOS command SYS can be used to recover, that is, DOS boot floppy disk system, the implementation of SYS C: command, if the response "System transferred "indicates that the two systems has been hidden file transfer to your hard disk, if the response to" NO ROOM FOR SYSTEM ON DESTIN-STION DISK ", said the transmission failed, because IBMBIO.COM must be occupied by the root directory of the respective first and second directory entry , and the need for a continuous front of the hard disk data area storage space, and these conditions have been damaged in other documents. The solution was to use a feature observed PCTOOLSCT the MAP FLLES disk image map that can identify the suspect file and delete it, until the SYS tell you until the SYS-TEM TRANSFERRED.
It is worth mentioning that, SYS command is not sent to the COMMAND.COM hard drives, to restored, can COPY command. The implementation of the "COPY A: \ COMMAND.COM C: \"

(4) hard disk formatting
In the repair done to attempt to do so, however, failed cases, the last resort is to reformat the hard disk, a complete hard disk format is divided into three steps, namely initialization (low-level formatting), establishing partition (FDISK) and the format (FOR-MAT C: / S). The operation of the hard disk is formatted in the following we are devoted to.

Second, the hard disk read and write errors when using the maintenance

1. The hard disk can not read and write files

Hard disk drives After a period of use, suddenly can not call some of the document.
The reasons for this failure the following two points: First, the use of information within the disc for some time after the natural loss; 2 is a user to use the hard disk properly, causing the information in an artificial disc is lost. Such as the proper head to read, write operation, a sudden power-down or shut down; another example, head work, the plate body subject to greater vibration, is a collision between the head and the platter, resulting in the user zone data disc or track was damaged.

This troubleshooting method is to call the system file FORMAT.COM to re-format your hard drive and then make a backup copy of the file back to the hard drive. At this point, such as using CHKDSK System File Checker may be displayed on the screen XXXXKB BAD SECTORS.

2. The hard disk can not be started

Hard disk drives After a period of normal use, a sudden can not boot up the operating system, such as the call to C drive, the screen displays "Invalid drive specifica-tion", shows call an invalid drive.
Rise to the possibility of such failures are manifold, which include soft fault. 00 tracks the presence of soft failure is one of the main failures leading to the above, here from a software maintenance point of view on the situation and maintenance of the 00 tracks means.
In the 00 tracks on system files and the hard disk bootstrap procedures, and 00 tracks is also head of the reference point to find other tracks. Therefore, the 00 tracks and 00 tracks of good and bad information have a direct impact on the hard drive can work properly. If used improperly or some kind of accident has damaged the 00 tracks on the written document, then after the boot, C drive can not boot the operating system, or even the head simply can not seek to read and write files. At this point, without formatting C drive is like mine, so when the user is called C drive, the screen will display "Invalid drive instruction." Exclude this fault is physically re-formatted drive C, re-DOS operating system partition and re-formatted region, and it is copyed into system files.

Because there are two hard disk boot record (assuming the hard disk is divided into a partition), one is the master boot record, one is the partition boot record. Master boot record cleared and re-write can use the physical format (low-level formatting) program (LOW-FORM.EXE, DTCFMT.EXE), thereby foregoing the process of troubleshooting, the first to use the physical format. The second step is to use DISK.COM right to partition the hard disk partition information and to be registered in the master boot sector, but it does not change the master boot record code execution. The third step is the use of FORMAT.COM region of the DOS format, because the master boot record does not belong to any partition, so FORMAT.COM program can not clear the master boot sector of any information. After the completion of the above three steps, and then operating system files written to the hard disk, thus, re-generate the hard work not be completed until this time, the hard drive already has the ability to bootstrap, you can use.

When using a floppy disk drive A boot after the operating system can display hard disk in the file directory, but can not boot from the hard drive operating system.

This occurs generally due to the system file is not written or damaged. Operating system files, a total of three components, namely, a two hidden files and COMMAND.COM files. Two hidden files are written in the 00 Road, the event of a failure, then the host can not boot the operating system.

Troubleshooting method is to use FORMATC: / S / V command to conduct a re-format the hard disk and then copy the backup of user files back to the hard disk can be restored to use.

Hard disk repair soft errors

2009-12-21T18:37:00.000-08:00

In fact, a large number of hard drive failures are soft failures, such failures also accounted for a large proportion of computer failures, and these failures can be users themselves, and the following, we mainly target a number of soft errors frequently occur phenomenon, about the maintenance of their skills.

First, the maintenance of the hard disk bootstrap failure

Practical application, the hard disk bootstrap failure is very common, hard disk bootstrap failure generally have the following symptoms:
Show "BASIC ... OK", enter the ROM BASIC.
Display "Invalid partition Table", is invalid partition table.
Display "Error loading operating system", read boot record failure and enter an infinite loop.
Shows "Operating system missing operating system" is not the operating system.
Show "NOn-System disk or disk error"
"Replace and strike any key when ready", read boot error.
Shows "Disk boot failure", Disk Boot failure into an infinite loop.
Show "Bad or missing command interpreter", COM-MAND.COM no or destroyed.

1. With the hard disk to start the boot process module and its boot

The hard disk from the hard disk of boot ROM BIOS, the hard disk master boot record, DOS boot record and system files completed. ROM BIOS, a total of 8K bytes, providing self-test, bootstrap capability and the establishment of the hard disk I / O and a series of operations, contained in the hard disk of boot module is the interrupt routine INT19H; hard disk master boot record in the 0 column 0 a sector (physical sector), before the row of logic 0 sector, including the hard disk boot loaders and partition information table, sector of the last two bytes "55A", is a hidden sector, with the DEBUG command or DOS function call INT 21H and were unable to read and write, usually provided by the ROM BIOS interrupt service routine INT13H hard to read and write an absolute, DOS Boot Record partition the hard disk 0 column 0 2 sector (physical sector, the entire hard drive was placed under DOS partition), that is the logical sector 0 to end the logo is also a "55AA".

The system power-up, the computer's execution flow is as follows:

CPU into the reset state of well-Qiang Chi CS: IP = FFF: 0000H, the address obtained from the first instruction (jump instructions).
The system transferred to the ROM BIOS program areas, the implementation of self-test procedure, if the self-test is successful, directing the INT19H systematic guidance, or reveal the error message and enter an infinite loop.
INT19H first tries to reset the floppy disk system, if successful, then read the first one of the DOS floppy boot record to the starting address 0000:7 C00H memory cell implementation, and then enter the DOS, or reset the hard disk system.
The success of the reading of the hard disk master boot record to the starting address 0000:7 C00H memory unit, and implement the master boot process, if the reset fails, read the master boot record error, or hard physical first one the last two bytes are not "55AA" , have shown that:
"BASIC ... OK" into the ROM BASIC.
The hard disk master boot program main function is to identify the current active partition, that is, view the partition information in the table 4 partition boot flag, when the DOS partition boot logo 80H, while the other partition 00H, will read the memory DOS Boot Record 0000:7 C00H Department.
If the four partition did not boot logo (80H), then the hair INT18 instruction into ROM BASIC;
If the boot flag (80H) more than one or a partition for the boot flag is neither 80H, then the non-00H, is displayed "Invalid partition table" and enter an infinite loop.
Find the active partition, the master boot record program attempts to read the memory, DOS Boot Record 0000:7 C00H Department, if the read fails, it displays: "Error LoadongSystem" and enter an infinite loop.
Read the success of the DOS boot sector checks whether the last two bytes of "55AA", the correct implementation of the jump 0000:7 C00H just read into the DOS boot process, if not, then the Show:
"Missing operating system" and enter an infinite loop.
Guide the process to AH = OINT13H command reset disk system, if the failure is displayed:
"Non-system disk or disk error"
"Replace and strike any key when ready"
Wait for keyboard input in order to shift INT19H re-boot.
If successful, then the calculation of the file directory area and the file data area start-bit sector numbers, and read the root directory of the first one to 0050:007 H office, if the read fails, an error message is displayed on.
If correct then the reading of "IBMBIO.COM" file into memory. If the reading error is displayed:

"Disk boot failure" into an infinite loop.

If the reading success, by IBMBIO.COM, IBMDOS.COM and COMMAND.COM three DOS system files, continue with the installation, during which, if can not find COMMAND.COM or the file is corrupt, then the show "Bod or missing command interpreter ".
Otherwise, a normal guide, until the system prompt, waiting for users to type a DOS command.
At this point, the system into DOS working condition.

2. Bootstrapping failed hard disk repair

If a normal hard disk drives, hard disk bootstrap failure and hard disk master boot module, DOS boot modules and system files are closely linked. For example, boot into ROM BASIC is likely to damage the hard disk master boot record; and failure to guide reveals the error message, then with the partition information table, DOS boot record and system files on damaged or missing. For a different error message, we should find out the crux of the problem and then take corresponding repair method is presented as follows:
(1) repair the hard disk master boot record
Using the hard disk master boot module versatility, from another of the normal and hard disk partitions on the same computer access to the module, and then write back to the hard disk failure, this method is simple and quick, even for the master boot block structure, a very shallow understanding of , did not find it difficult to operate, the steps are as follows:
① to start a normal computer, and drive home an A blank, formatted disk, type the following statement sequence:
C> DEBUG
-A 100

? ? ? ? : 0100 MOV AX, 0201; reading a sector
? ? ? ? : 0103 MOV BX, 1000; set buffer CS: 1000

? ? ? ? : 0106 MOV CX, 0001; reading 0 Column No. 1
? ? ? ? : 0109 MOV DX, 0080; the hard disk head, No. 0
? ? ? ? : 010C INT 13; disk I / O interrupts

? ? ? ? : 010E INT 20; program termination.
? ? ? ? : 0110

-G = 100

-W 1000 0 50 1

At this point, has been good and hard disk master boot block and write the logic in the floppy disk sector 50H.
② The DOS floppy disk boot failure of the computer, after entering DEBUG into the floppy disk drive A, type the statement in the DEBUG state sequence:

-L 1000 0 501

-A 100

? ? ? ? : 0100 MOV AX, 0301: to write a sector
? ? ? ? : 0103 MOV BX, 1000

? ? ? ? : 0106 MOV DX, 0001

? ? ? ? : 0109 MOV DX, 0080

? ? ? ? : 010C INT 13

? ? ? ? : 010E INT 20

? ? ? ? : 0110

-G = 100

At this point, the hard disk master boot record repair is completed.

Routine maintenance of the hard disk-2

2009-12-21T18:35:00.000-08:00

Fault 1: The system does not recognize hard drive

The system can not boot from the hard drive from the A disk can not boot into the C drive, use the CMOS the automatic monitoring function can not be found in the presence of the hard disk. Most of these failures appear in the connecting cable or IDE port on the hard disk failure is unlikely in itself and can be re-plug hard drive cable or change IDE port and cable to replace the test, you'll quickly find fault lies. If the new hard drive is not connected to be accepted, a common reason is the master-slave jumpers on the hard disk, if an IDE hard disk online access two hard disk drives, it is necessary to distinguish the relationship between master and slave.

Troubleshooting 2: the hard disk can not read or write, or can tell

Such failures are generally due to failures caused by CMOS settings. CMOS in the hard disk drive a direct impact on whether or not the correct type of normal use. The machines are now supported "IDE Auto Detect" function can automatically detect the hard disk type. When the hard disk type error, and sometimes simply can not start the system, and sometimes be able to start, but it will read and write error occurred. Such as CMOS, the type of hard drive is less than the actual hard disk capacity, then the hard drive behind the sector will not be able to read and write, if it is multi-regional state of the individual partitions will be lost. There is also a major cause of the malfunction, since the current logical arguments support the type of IDE hard disk can be used "Normal, LBA, Large", etc., if the normal mode, installed the data, but in the CMOS, replaced by other models , the hard drive read and write errors occur failure, because the mapping relationship has changed, and will not be able to read the original location of the correct hard drive.

Troubleshooting 3: The system can not start

For this failure is usually based on the following four reasons:
1. Corrupted master boot program
2. Partition table is damaged
3. Division of effective bit error
4. DOS boot file is corrupted

Which, DOS boot file is corrupted most simple, using a boot disk boot, after a boot file to the system transfer on it. Master boot program significant bit of damage and damage to the general area can also be used FDISK / MBR to solve a mandatory override. Partition table is damaged is more trouble, because they could not identify the partition, the system will not partition the hard disk as a bare disc treatment, resulting in some software not work. However, there is a simple way - using Windows 2000. Finding with Windows 2000 systems, the damaged hard drive Guashang Qu, boot, due to Windows 2000 in order to ensure the stability of the system hardware will have a new hard disk to scan Jieshang Qu. Windows 2000 hard disk scanning program CHKDSK corrupted for various reasons, have a good repair capacity hard drive, scanning finished basically repair a hard drive.

There is also a form of partition table is damaged, here I refer to "zoning map", the specific performance of the emergence of an active partition and the same partition. Including the same file structure, content, partition size. If the content in any area of the district made a change, will be reflected in another place, seems to be the same as the shadow map. I have come across before, 6.4G hard disk into a 8.4G (mapping of the 2G C-Zone). This problem particularly awkward, this problem does not affect the use, not the words will not fix problems, but to repair, NORTON of DISKDOCTOR and PQMAGIC all had become illiterate, to partition the hard disk capacity and the actual size of the overall inconsistency turned a blind eye No problem, you mouthful perfunctory. Tackle this problem, only the GHOST coverage and use NORTON rescue disk to restore the partition table.

Fault 4: hard disk bad sectors

This is a shocking and feared word. Recently, IBM word of mouth and therefore diminish quickly. When you use the system comes with Windows system ScanDisk SCANDISK scan the hard disk when prompted to say the hard disk may have bad sectors, and then flashed a horrible blue, Xiao Huang box one by one slowly stretching open, then, been in a box marked with a "B" ... ...

In fact, most of these bad sectors is a logical bad sectors, it can be fixed. Obviating the need for repair (it is said the reason why development of self-test tool vendors is that they succumb to repairing the hard disk is simply a good half of this "brutal" fact).

So, when there is such a problem, how should we deal with it?

Once with the "SCANDISK" If the program prompts when scanning the hard disk has bad sectors, first of all we should re-use of the brand drives its own self-inspection procedures for a full scan. Note, do not select quick scan, because it can only detect about 90% of the problem. In order to assure themselves, in that more time is worth it.

If the check result is "successful rehabilitation", that can determine the logical bad sectors, you can shoot each of the offerings of breath; If not, then there is no possibility of repair, if your hard drive is also shelf-life, that it quickly to replace the bar.

As the logical bad sectors merely been marked cluster number will no longer be assigned to the files use the. If it is the logical bad sectors, just reformat the hard disk on it. However, in order to prevent a possible drop formatted phenomenon (because the cluster has made a mark on a number that is a bad cluster, formatting program may not check on the acceptance of this "reality", then discard the cluster), better re-partition, use the such as the IBM DM sort of software is still quite fast, or GHOST coverage can be, but both programs are more or less to lose some data.

Fault 5: Hard disk capacity and the nominal value is clearly incompatible with

In general, the hard disk formatted capacity will be less than the nominal value, but this gap will not be more than 20%, if the two differ greatly, you should enter the BIOS settings at boot time. Depending on your hard drive in which to make a reasonable setting. If that does not, then may be your motherboard does not support large-capacity hard drive, this time you can try to download the latest motherboard BIOS and make an update to resolve. Such failures more in high-capacity hard drives and motherboards with older when. In addition, because a sudden power failure and other reasons to make BIOS settings confusion may also lead to this failure from happening.

Fault 6: No matter what the equipment is not properly using the guidance system

Such failures are generally due to the hard disk has been virus "logic lock" lock caused by the "hard logic lock" is a very common means of mischief. In a logical lock, regardless of whether the use of any equipment does not properly boot the system, or even floppy disks, optical drives, hard drives are the same double-hung has no effect.

"Logical lock" locking principle: the computer boot DOS system will search all volumes is the order, when the DOS is directed, first of all to go find the master boot sector of the partition table information, and then search for the logic of the extended partition plate. "Logical lock" changes the normal primary boot partition record, will expand a Logical disk partition the first point to themselves, making DOS at boot time to find to the first one Logical disk, the search for the next Logical disk is always to find their own, so to to form a loop.

To the "logic lock" unlock the easier way is to "hot pluggable" hard power. Is when the system is started, the first is not to be locked to the hard disk power-up, and then to the hard disk to start the completion of "hot plug" on the power line, so the system can properly control the hard drive. This is a very dangerous approach, in order to reduce the level of risk, encountered a "logical lock", all of you is best in accordance with the following a few relatively simple and safe manner.

1. First, to prepare a boot disk, and then in other normal machines use the binary editing tool (recommended UltraEdit) modify IO.SYS file on the floppy disk (remember the first, before the amendment changed the properties of the document normal), specifically Search in this document which the first one "55AA" string to find the future value can be modified for any other. This modified system with the floppy disk you can be locked with a smooth hard drive started. However, the normal time due to the hard disk partition table has been damaged, you can not use "Fdisk" to delete and modify the partition, then you can use software such as rehabilitation or reconstruction of Diskman partition can be.

2. Because the DM is not dependent on the motherboard BIOS to recognize the hard disk drive tool, even if the hard disk will be in the motherboard BIOS set to "NONE", DM can also identify the hard disk and partition and format and other operations, so we can use the DM software to unlock the hard disk.

First, the DM Kaodao a system disk, the connected and locked hard disk boot, press "Del" key to enter the BIOS settings, IDE interface, all set to "NONE" and save, then exit, and then use the floppy disk to start the system, namely, can "lock" to start, because this time the system does not simply mean that the hard disk. Starts to run DM, you will find that DM can identify the hard disk, select the hard disk partition format on it. This method is simple and convenient, but there is a fatal disadvantage is that the data on the hard disk retain his job.

Fault 7: boot disk can not be bootstrapped, the system does not recognize hard drive

This failure is often the most terrifying. Produce this failure is mainly due to the hard disk master boot sector data has been destroyed, the performance of the hard disk master boot partition flag marks or missing. This failure is often the culprit is a virus, it will overwrite the wrong data to the master boot sector. Some common anti-virus software on the market are available to repair the hard drive feature, we try. " onmouseout="this.style.backgroundColor='#fff'">However, if no such tools at hand disk, you can try to all the data written to the primary boot sector 0, and then re-partition and format, its methods are as follows: a clean DOS boot disk with the computer, enter A: \> After enter the following command (note in brackets):
DEBUG（进入DEBUG程序）" onmouseout="this.style.backgroundColor='#fff'">A: \> DEBUG (entering DEBUG program)
-F 100 3FF0 (clear the contents of the data area to 0)
-A 400 (add the following command)
MOV AX, 0301
MOV BX, 0100
MOV CX, 0001
MOV DX, 0080
INT 13
INT 03
-G = 400 (implementation of the disk operations command)
-Q (retired DEBUG program)

In this way can the general resurrection of your hard drive, but to re-partition and format the data inside may beware. These are the hard disk in the daily use of some of the common faults and solutions, hoping to inspire all of us. Hard drive failure is very serious, if not some of the above approach can be used, then it might be mechanical failure. Because the structure of the hard disk rather complicated, so I do not recommend that users themselves demolished, but should be recourse to professional maintenance

Routine maintenance of the hard disk

2009-12-21T18:34:00.000-08:00

First, the hard disk when using the common faults

1. For their older machines to upgrade, we put a new large hard drive, and the motherboard does not recognize:

Due to the existence of an earlier board 8.4GB capacity constraints, but now the hard drive capacity has greatly exceeded this limit. To solve this problem, one defines a new extension INT 13H. The new operating system does not use INT 13H disk addressing registers to pass parameters, it uses the operating system stored in the memory address of packets. Address package to save the 64-bit LBA address, if the hard disk supports LBA addressing, put the low 28 directly passed to the ATA, if you do not support, the operating system should first convert the LBA address of CHS address, re-transmission and handed ATA Interface . In this way, can be achieved on the basis of the ATA bus, CHS addressing the largest capacity is 136.9GB.因此. To normal use large-capacity hard drive, from the soft and hard in order to address. First gave the three kinds of solutions, for your reference:
(1) to upgrade the motherboard or BIOS:
The new motherboard BIOS interrupt INT 13H to read and write to the disk was extended, generally after the motherboard BIOS can be upgraded to support more than 8.4GB hard drive. In addition, you can use the BIOS expansion card (it has large-capacity hard drive provides the correct LBA addressing support).
(2) the use of DM's own hard drive partition software partition:
Use a special driver (usually the hard disk partitioning software that comes with DM), also provides INT 13H extensions. Resulting in the case of fixed motherboard that supports large hard drives. Generally speaking, the software can effectively convert the various parameters of large-capacity hard drive, the BIOS starts, the operating system will automatically pre-loaded to full capacity of the purpose of using the hard disk.

(3) using WIN98 or above operating system, hard disk format using FAT32, and make a reasonable partition.

2. Add a new hard drive after the system is unable to start:

Face this problem may be due to your WINDOWS if they are not installed in C drive but on the other drive letter. After the installation of a number of hard drives in the original hard drive where there are multiple partitions will cause the drive letter of the staggered, resulting in the original hard drive letter change. WINDOWS can not find the installation when it starts the default location of the file related systems naturally can not start properly. In the case of multi-partition hard disk partition is essentially this: the original C drive is still seen as C drive, while the second block of the primary hard disk partition will be considered as D drive, and then the first one the other hard disk drive begin to run from the E drive, then, is the second hard drive and other partitions. To solve this problem, is that when connected to a second hard drive when its re-partition, delete the primary DOS partition, only to expansion of area, so that the letter will not be staggered.

3. BIOS does not detect the hard disk, or in self-test when "HDD Controller Failure" the words:

If it is not detected hard drive may be connected to IDE hard drive interface cable to connect a good bit. Of course, if I DE cable connector connection is bad or there some broken, there will be such a phenomenon. If the above components through the replacement or do not improve, you have to consider the question of hard power, is not the power cord is damaged or not good contact. If it is self-test error, is also possible that the above-mentioned problem. Of course, if you will fall into the self-test disc when there is a serious periodic noise, it shows that mechanical control of your hard disk drive arm parts or have a problem.

Second, the hard disk when using the Notes

1. When the hard disk is being read and write can not be a sudden power failure

The hard disk read and write operation, in a high-speed rotation among the (currently usually 7200 r / min or 5400 r / min), should the power outage, could cause friction between the head and severe damage to the hard disk platter. So best not to a sudden shutdown, shutdown must pay attention to whether the panel on the hard disk light is still blinking, only when the hard disk light stops flashing, the hard disk read and write only after the end of the shutdown.

2. Pay attention to maintaining environmental hygiene

In the damp, dust, powder exceeded the environment seriously when you use the computers, there will be more absorption of pollutants to the surface of printed circuit boards, as well as within the spindle motor. Moist environment also make insulation resistance of electronic devices such as job instability. Must therefore be to maintain sanitation, reduction of air humidity and dust content. Remember: general computer users can not open the hard drive cover on their own, or in the air of dust into the hard disk, in the head to read, write operation scratched disc, or head. So when the hard disk fails, do not self-demolition drive enclosure, it should be transmitted to the professional factory repair.

3. Note that the hard disk shock

Hard drive is a high-precision equipment, work the surface of the floating head in the disc height of only a few microns. When the drive is read-write state, the event of a large shock, it could result in head impact with the disc, resulting in damage. So do not moving the operation of the computer. In the hard drive installation and removal process should be more careful, hard disk movement, transportation is strictly prohibited bump, it is best protected with foam or sponge packaging look to minimize vibration.

4. Pay attention to controlling the ambient temperature

The use of the hard disk should pay attention to anti-high temperature, moisture, anti-electromagnetic interference. Hard work will produce a certain heat, the use of existing cooling problems. Temperature to 20 ~ 25 ℃ is appropriate, the temperature is too high or too low will cause the crystal oscillator clock frequency change. Temperature can also cause failure of the hard disk circuit elements and magnetic media will also be due to thermal expansion effects caused by recording errors; the temperature is too low, moisture in the air will be condensed in the integrated circuit components, causing short-circuit. Humidity is too high, the electronic components may be adsorbed surface layer of water film, oxidation, corrosion of electronic circuits, resulting in poor contact, or even short-circuit, but also to make a change in magnetic media, magnetic force, resulting in the data read and write errors. Humidity is too low, easy to accumulate a large number of rotating machines generated by electrostatic charge, which will burn static CMOS circuits, the adsorption of dust and damage to the head, scratching the disk piece. The humidity inside the room at 45 ~ 65% is appropriate. Note that the air to keep dry or frequently to the system power-up, relying on self-heating machines, water vapor will evaporate. Also, try not to drive near strong magnetic field, such as speakers, speakers, motors, radio, mobile phones so as to avoid the data recorded in the hard disk damaged due to the magnetization.

5. Develop the use of a good habit and arrangement of the hard disk

The root directory of the general store system files and subdirectories, and other documents stored as little as possible. Always run the Windows Disk Defragmenter to organize the hard disk. Note that often delete the "garbage station" and the "\ WINDOWS \ TEMP" directory in the temporary files.

6. To prevent the destruction of computer viruses on the hard disk

Hard drives are the major targets of computer virus attacks, should pay attention to using the latest anti-virus software to prevent viruses. And pay attention to the protection of important data, and regular backups.

7. The hard drive to take France

Take the hard disk when you do not bump in the hand, this is just one of the requirements; Another taboo is "static." Climate dry easily generate static electricity, be careful in this case if the hard disk on the back of his hands touch the circuit board, the "static" is likely to be hurt on the hard disk of electronic components, leading to not work correctly. The correct posture should be in hand to seize the hard drives on both sides, and to avoid their direct contact with the back of the circuit board. In addition, some vendors (such as Seagate) in its hard outer layer of cuticle on the package, this cuticle addition to having the shock, but also to protect the circuit board in which, so users can pick up when the hard disk less scruples a.

Hard disk is not self-test

??? A general hard disk self test fail, if not the master boot dos boot module or modules have been destroyed (such as virus infection), then the other symptoms are basically caused by the external hardware. Software, antivirus software can be used to guide district killing virus, or norton, debug and other repair (cumbersome), the hardware self-test in accordance with the boot prompt after the information to analysis.

1, Power On Self Test to complete prompts the following error message:?? Hdd? Controller? Failure? Press? F1? To? Resume?
When the above information, you should focus on inspection and the hard disk on the power lines, data lines interface, whether loose, their connections and signal lines reversed and so on.
If not the above reasons, then the hard drive for a try block, it is possible the hard disk itself is broken?

2, after the start of memory self-test displays the following message:? Fdd? Contreller? Fanilure? Hdd? Contreller??? Fanilure? Press? To? Resume?

Hard disk damage repair

The most finicky computer components should be hard drive. Although the manufacturing process with the continuous progress, this situation has changed, a number of hard disk manufacturers such as Quantum also issued a related new technologies, such as Quantum seven generations in order to reduce the hard drive started by the impact shock developed sps protection system, as the body count on the hard disk "strong" together. However, the shortcomings of a bad hard drive easily, and has not been fundamentally changed. The hard drive to save the precious time of data. The hard disk is a logical damage be it, big deal to reinstall software, but the physical damage it? In fact, as long as the situation is not particularly serious, with some means, and in general can solve the problem. First, let's take a look at the hard disk has physical damage, that is, after what has been the phenomenon of bad sectors.

1, read a file or run a piece of software often wrong, or to operate successfully after a very long time, during which continued to read the disk drive and issued harsh noise, this phenomenon means that the hard drive containing data on some of the fan area has been bad.

2, boot the system can not boot the hard disk, floppy boot disk can be transferred after the letter, but can not enter, with the sys command conduction system can not succeed. This situation is more serious, because it is likely that the hard disk boot sector out of a problem.

3, normal use of a blue screen when the computer frequently for no reason. For the previous three kinds of situation, we generally have a way to make more or less remedial. The following provides several ways to fix bad sectors on the hard disk should be noted that priority should be given top surface method.

1, scan the hard disk. First, from the most simplest way to start. In Explorer, select the drive letter, right-click on the shortcut menu, select "Properties" in the "Tools" item on the hard disk to make a full scan processing, and on the possible bad clusters for automatic correction. "?提示符后键入"scandisk?x："?来扫描硬盘，其中"x"是具体" onmouseout="this.style.backgroundColor='#fff'">For the above situation in the first two kinds of phenomena that can not enter the system, you can boot the machine with the boot disk, and then in "a:>"? Prompt, type "scandisk? X:"? To scan the hard disk, where "x" is a specific hard disk drive letter. For the bad cluster, the program will be black red of the "b" (bad) are marked.

2, cold treatment. In fact, the first one kinds of methods often does not work, because of "bad sectors" auto repair is largely in terms of the logical bad sectors, but not automatically repair physical bad sectors, it is necessary to consider these bad sectors as " cold treatment. " The so-called "cold treatment" is to make mark in these bad sectors, do not use, untouchables also avoid them since. 1 ways to remember the location of the bad sectors, and then high-level formatting the hard disk, there will be bad sectors in the region divided into a zone, then went to access this area, do not file. I want to clarify is not to save hard disk space for this division was too much "economic", but should leave appropriate leeway, because to read bad sectors around the "good" was an unwise - with the spread of bad sectors , if used with bad sectors relying too close to "good Road", then before long, the new bad sectors on the hard disk in turn appear?

3, with some software for the hard disk for processing. One of the most typical is the partitionmagic. Here for 4.0 version, for example: Scan the hard disk can be directly partitionmagic4 in the "check" command to complete, but the command no auto-repair function, so it is best to call in the partitionmagic4 associated procedures windows98 to complete this task. 3,0 sector is damaged. For the damage to the hard disk 0 sector the situation looks difficult, but not incurable - as long as the scrapped 0 sector shielding, but instead on the line with a sector, and the completion of this work, the ideal software is pctools9 .0, specifically, is pctools9.0 in de tools, to note that, in changing sector is completed, only the hard disk partition table will be formatted before the information is written to a sector (now as a 0 sector of).

4, low-grid. Less than a last resort, this move is best not to use: namely, the hard disk for low-grid. Because of the hard disk for low-grid there are at least two harmful effects: First, wear disc, and second, to have the hard drive for bad sectors, low-grid will accelerate the proliferation of bad sectors. Finally, there is that it is related to the contents of the motherboard bios to be set up properly, especially for some tx level before the motherboard chipset, the absence of the ability to automatically recognize the hard disk size, often a result of improper settings affect the use of hard drives, ranging from the hard disk can not make the best use, while in the hard disk damage. Described above is the hard drive when there is physical damage solutions. However, these methods are mostly negative, at the expense of the hard disk capacity at a price.

With the hard disk bad sectors, if not because of the problem of aging, then usually in the use of something wrong, such as the right too frequently defragmented the hard disk, memory, hard drives too few applications to the frequent visits. And ignore the dust on the hard disk drive heads because the deal will lead to difficulties in positioning lead to mechanical failure. In addition, the FSB cpu overclocking caused by increased, forcing a long drive to work at too high a voltage will cause malfunction, therefore, usually use the hard drive should be to exercise caution as the best way

Disk drive fault detection and repair

When the hard disk failure, the first thing is to check the computer's BIOS (Basic Input / Output System) settings. Check the Hard Disk Size (size), or MB and so on, look at the figure and the actual installed on the computer hard disk are the same size.

If this does not work, you can try to automatically identify (or your own attempts BIOS), but the BIOS can not call the hard disk, then replace the value of a typical, is the ominous "not installed" off-label. These results suggest that the problem than the BIOS settings directory even more serious. So on this is to switch off computer, pull out plugs, open the computer case time.

Before opening the computer case, first to confirm whether this is the guarantee period will lapse. Next, let your computer access to the metal frame, good produce ground effects (this can release static electricity to prevent harm to the system components), and then unplug the computer's power plug. Open the computer case, and then check the connections on the hard drive connector. If one or even two joints are off the case, would draw a line on, be careful not to bend the pin.

At the same time, but also the inspection is not linked to the hard drive end of the transmission line in order to ensure that it is connected to the. If you find loose joints, and will insert it back; the interface if it has not been specifically designed for the connector, then you have to carefully review whether the board surface printed with a small "one." That is, pin 1 should be positive right place.

Once you have done these things, and the hard disk but still a move. At this point, it is time to surrender and to call customer support department of the time. Perhaps they come across the same problem before, even as we have talked about ways other than simple solution. However, the case eventually found sad fact is that your hard drive has been made a hell, please carefully check whether your hard drive is still within the guarantee period.

Hard disk damage repair

Scandisk Scandisk to solve the logical bad sectors hard drives the most commonly used tools, and our common Format command can not be played on any hard disk damage repair role, which we need to understand. If the hard disk of the bad sectors, we can in the Windows system environment, in the "My Computer" and select the drive letter to address, choose its "Properties", in the event of the "Tools" button to select "Error-checking status" , click on "Start Check" and then the "Scan Type" selected "full inspection", and "automatic fix error" branded "hook" and then "Start" button, it will do a full scan of the disk drive handle, and right possible to do automatic correction of bad clusters. Second, in DOS mode, the hard disk has bad sectors, the computer starts normally run Scandisk will automatically scan and bad with black red cluster of "B" (bad) are marked. Of course, if the system at boot time without disk scan or have not have access to Windows systems, we also use a floppy disk or CD-ROM boot disk your computer, in the appropriate drive letter, if the "A:" run Scandisk *: (Note: * In order to scan the hard disk drive letter), then enter the corresponding need to scan the hard disk partition repair repair.

Others, such as Norton Toolbox NDD "disk doctor" and Pctools and other related tools to scan the hard disk repair hard disk bad sectors are the most common method, its usage is very simple, and many newspapers and magazines are also described (in this case I will not dwell on a).
[iduba_page]

If the hard disk appeared beyond repair bad clusters or physical bad sectors, we used some of these bad sectors disk software is divided into separate areas and a hidden, they could then extend the service life of your hard drive.

If the system shows "TRACK 0 BAD, DISK UNUSABLE", meaning "zero track damage, the hard disk can not use" or use ScanDisk to scan your hard disk when other sectors of its 0 red "B". The hard disk sector 0 is damaged, it is our fault more headaches, most people tend to appear like a failed hard disk as scrap. In fact, rational use of some software on disk, the scrapped 0 sector shielding out, but replaced with a sector can play a life-giving effect, such as software, such as Pctools9.0 and NU8 so.

Method 1: We first used Pctools9.0 as an example for illustration. The above-mentioned a 2.1G hard drive failure, you start your computer with the disk, run the Pctools9.0 directory DE.EXE file. Select the main menu and then select the Drive, after the Drive type items into the election Physical, according to spaces selected, press Tab key to switch to the Drives item, select the hard disk, and then after the return to the main menu enter OK. Open the Select menu will appear, Partition Table, selected after entering the hard disk partition table information. The hard drive has two partitions, locate the C zone, the partition is started from the hard disk 0 cylinder, then it will be a partition Beginning Cylinder 0 can be changed to 1, and save, then exit. Restart the computer and press Del key to enter COMS setting, run the "IDE AUTO DETECT", you can see CYLS into a 781 by 782. Save exit and re-format the hard disk partition to make it back to life.

Method 2: Norton NU8.0 also better to use. For example, a 1.28G hard disk 0 track breakdowns into NU8 toolkit directory, run the main program NORTON.EXE, and then the election could be the first "remedial Disk" RESCUE option on the hard disk boot sector, partition table and other information to back up. Then select "Disk Editor DISKEDIT", after the successful operation of the election "object OBJECT", select "Partition Table" shows the hard disk after the parameters are as follows: Surface SIDE To 0-63, cluster CYLINDER for 0-255, Sector SECTOR 1 -63, its master boot record and partition table information should be in the 0 side 0 column 1 sector. We have to do is to start its C disk sectors from 0 surface 0-chu, a sector into a sector 0 face a column, move the cursor can be manually modified. Also need to say is that changes in value according to specific circumstances. Exit to restart the computer after the last Save, use Format command to format the hard disk as you normally would use. Require special attention, the reconciliation must not be reused after the hard drive Fdisk under DOS partitioning tools such as re-partition of its operations, so that its also starting to change the hard disk cylinders.

If the above strokes do not work, then have to use the onboard hard disk drive manufacturers with low grid program, or presented with the plate of low-grid programs such as DM, LFormat and other low-level formatted the hard drive completely processed, it can drive to re-order to exclude a number of bad sectors.

Physical bad sectors hard drives

If you have DOS can go to C drive, while the hard disk is not working properly, it is likely to be the hard disk has bad sectors occur. In general, the hard disk bad sectors can be divided into the logical bad sectors and physical bad sectors. Generated when the logical bad sectors are generally not seriously affect the use, it is likely to be the physical bad sectors.

Physical bad sectors we are dealing with the core idea is to cluster these are bad sectors into a single partition, and hide to avoid the other programs call, so that you can prevent the proliferation of bad sectors, so as to avoid greater losses. For this processing, we mainly use Partition Magic6.0 this software under DOS.

In the DOS interface into the PQ 6.0, we first used under the Operations menu, Check For Errors command to determine the physical location of bad sectors, because PQ6.0 this feature very well, unlike Windows, the Scandisk as often misdiagnosed.

PQ6.0 the real power lies in its ability to cluster all the possession of bad sectors marked with a special calibrated out, and you can select all of these bad clusters, and then they are divided into a separate new partition. This is a graphical operation, it is very convenient. Subsequently, we should bear in mind that hidden partition is full of evil, so as to ensure that it will not be called. At this point the use of Advance under the Hide Partition menu commands can be achieved.

After possession PQ6.0, physical bad sectors are really not difficult to solve, and can effectively prevent proliferation. But should be noted that, in any event, this time the hard disk is already in sub-healthy state, in which the data is still very dangerous. PQ6.0 after treatment with the physical bad sectors, what piece of the hard disk is also difficult to say how much time, it depends on luck.

Low-level DOS boot failures - lock logic

Hard logic of lock is a very common means of mischief. In a logical lock, regardless of whether the use of any equipment does not properly boot the system, or even floppy disks, optical drives, hard drives are the same double-hung has no effect.

To solve the problem logically locks, we should know the root of the problem. In fact, DOS system startup, it will search all Logical disk order. First, find the master boot sector of the partition table information, it is located in the hard disk of the zero-zero-cylindrical head of the first sector of OBEH address of the beginning of the, when the partition information for the beginning of the 80H that is the main boot partition, the other for the extended partition, the primary boot partition is defined as the Logical disk C drive, and then search for the extended partition Logical disk, is defined as the D drive, and so find the E, F, G ... ... logic of the lock is in this start with, modify the the normal primary boot partition record, will be the first one extended partition points to itself Logical disk, DOS at boot time to find to the first one Logical disk, the search for the next Logical disk is always to find their own so that a loop is formed .

For such problems, if you do not want the data on the hard disk, then deal with them very readily. We can all IDE interface in the BIOS will set NONE, then use the floppy disk to start the system, this time can certainly start, because the system simply do not drive. Then, we use the classic hard drive management software, DM has. As the DM may not rely on the motherboard BIOS to recognize the hard disk, so you can use DM to partition formatted so that we can completely solve the problem, and fail-safe, simple and convenient, the only regret is that the data retain his job.

There is also a way is also very worthy of recommendation, it can keep the hard drive data. First, to prepare a boot disk, and then in a normal machine, using a binary editing tool you're familiar with (UltraEdit, etc.) modify IO.SYS file on the floppy disk (remember to change the document before the amendment of the properties of normal), the specific Search in this document inside the first one "55aa" string to find the future value can be modified for any other. This modified system with the floppy disk you can be locked with a smooth hard drive started. However, the normal time due to the hard disk partition table has been damaged, you can not use FDISK to delete and modify the partition, but now can use the above to restore the partition table on the way to deal with.

As a storage device in a hard drive plays an extremely important role. However, due to the hard disk are magnetic media, so its life expectancy and stability of the memory and other devices not as good as when using all kinds of problems would inevitably arise. And make the situation more complex, due to the hard disk to the system involves setting the bottom, they are often not familiar Windows, resolve the problem, go to DOS must be dealt with under the terms of that for a lot of DIY novice a bit at a loss, and after all they have not experienced the DOS era.

Hard drive problems before the general symptoms of

If the hard disk fails, then the best early detection and timely take corrective measures. If you wait until the terminally ill, the hard disk of your valuable data is difficult to escape the. In general, the hard disk fails, there will be the following performance:
1. S.M.A.R.T failures prompt appears. This is a hard drive built-in hard drive manufacturers themselves inside the auto-detection feature is at work, there are prompted to describe your hard drive that have the potential physical failures, and soon there will not be running from time to time in the case.
2. In the Windows initialization crash. This situation is more complex problems should first rule out the possibility of other components, such as memory, poor quality, fan stall cause system overheating or damage caused by viruses and so on, finally if it is determined if the hard disk failure, and then dealt with separately.

3. Be able to enter the Windows system, run the program, but an error can not run disk scans, often slow and stagnant or even crash when scanning. This phenomenon may be hard drive problem, it may be Windows constant, daily soft fault, if the software is set to exclude the possibility of problems, you can certainly have the physical failure of the hard disk.
4. To enter Windows, run the ScanDisk found an error or even bad sectors directly, which does not need me to say, Windows will be a detailed inspection procedures for reporting.
5. In the BIOS suddenly could not distinguish between the hard disk, or even to identify, but also the operating system can not find the hard disk, which is the most serious failures.

Unfortunately, the great fortune - the destruction of the partition table

First, we should recognize the hard drive power interface and data lines do not fall off, and then enter the BIOS, use the "HDD Auto Detect" to detect the hard disk. If the BIOS can correctly identify the hard drive at this time, then at least your hard drive there is hope of treatment; Otherwise, I think we have no fuss, because I think our average DIYer tool at hand is essentially powerless.

In UltraEdit Find "55aa" String

CD-ROM or floppy disk boot system, you can try to enter the C drive letter, if you are prompted at this time can not find the C drive, then definitely be a good thing. This occurs is likely to be the hard disk partition table information has been destroyed, or are some kind of virus attack. If the hard disk for your data does not matter, you can first use FDISK / MBR command to unconditionally remove the contents of the partition table, and then use FDISK and other partitioning software to re-format the partition, generally this way we can solve the problem; and if you still need the hard disk the data, then the steps to take some work. The best time to have a kill-virus software or a motherboard with a gift related software, and then you can refer to the help documentation, generally the software will contain the command to restore the hard disk partition table, but also extremely easy to use.

For there is no antivirus disk users, we can use the NU 8.0 in the NDD repair, it will check the partition table errors. If it is found wrong, NDD will be asked if you are willing to modify, as long as you continue to answer YES you can correct errors, or the partition table with the backup off-line coverage of it.

Can be achieved with the Hide Partition

If the above method does not solve the case, can also use FDISK to re-partition, but the partition size must be the same as the original partition, which is especially important not to carry out high-level format, after partition, but use NDD to repair it. This will not only ensure that the hard disk can be repaired after the start, but the data on the hard disk will not be lost.

Fault Zoning active flag errors

In the hard disk master boot sector there are still an important part, that is its last two bytes: "55aa", the bytes of a valid symbol for the sector. When from the hard disk, floppy disk or CD-ROM starts, will detect these two bytes, if there is the view that there is a hard drive, otherwise it would not recognize the hard disk. Here can be used for the entire hard drive encryption technology DEBUG method can be used to resume processing. In addition, when the DOS boot sector not leading marks, the system starts will appear as: "Mmissing Operating System". Convenient method is to use the following DOS system, a common repair method.

DOS boot boot failures caused by

DOS boot system is mainly from the DOS boot sector and the DOS system files. System files include IO.SYS, MSDOS.SYS, COMMAND.COM, which is a DOS shell COMMAND.COM file that can be used to replace other similar documents, but the default state is essential DOS boot files. DOS in Windows 95 systems carry, MSDOS.SYS is a text file, is required to start Windows files, but only when you start the DOS can be without this document. DOS boot error, it can boot from a floppy disk or CD-ROM after using the SYS C: command transmission system, you can repair failures, including the boot sector and system files can be automatically repaired to normal.

Caused by failure to read and write FAT table

FAT table records the hard disk data storage addresses, each file has a set of FAT chain, store cluster to designate their address. FAT table corruption means that the loss of contents of the file. Fortunately, the DOS system itself offers two FAT tables, if the current use of the FAT table is damaged, can be used to cover the second repair. However, due to different specifications of the disk of its FAT table length and the address of the second FAT table is not fixed, so the repair must be properly find its correct position, a number of tools, such as NU and others who have such a repair, the use of very convenience. DEBUG can also be used to achieve this operation, that is using its m command of the second FAT table can be moved to the first table Division. If the second FAT table also damaged, you can not put the hard disk back to its original state, but the file data is still stored in the hard disk data area, can be used to repair the command CHKDSK or SCANDISK finally get *. CHK files, This is the lost data on FAT chain sector. If it is a text file can be extracted from a complete or partial content of the document.

Table of contents to guide the damage caused failure

Table of contents recorded in the file name of the hard disk and other data, the most important one is the starting cluster number of the document. Table of Contents In the absence of automatic backup feature, so if the directory is damaged a large number of documents will be lost. Of a method also used to reduce the loss SCANDISK program CHKDSK or method of recovery from the hard drive search out the *. CHK files, because the table of contents damage is only the first cluster number is lost, every one *. CHK file that is a complete file to change it's name can be restored most of the original document.

Accidentally deleted partition data recovery

When using FDISK to delete the hard disk partition, the surface is the hard disk of the data has completely disappeared, without formatting the hard disk will be displayed when you enter an invalid drive. If you know FDISK works, they will know just FDISK the hard drive to rewrite the master boot sector (sector 0 face 0 1) in the content, specifically, that is to remove the hard disk partition table information, while the hard disk in any partition The data have not changed. Can be modeled on the above-mentioned repair partition table wrong approach, that is to find ways to restore the partition table data can be restored the original partition and data. If you have already formatted partition, recovery partition, after an earlier, according to the following methods of data recovery partition.

Mistakenly formatted hard disk data recovery

In the DOS version of the state of high, FORMAT formatting operations have been established in the default state for recovery formatted disk information, is actually the disk DOS boot sector, FAT partition table and copy all the contents of the table of contents to the The last few sectors of the disk (because the latter sector is rarely used), while the contents of the data area has not changed. This command can be restored by running the UNFORMAT. Another DOS command also provides a MIROR disk used to record the current information for formatted or deleted after the resumption of the use of this method is also more effective.

Common Troubleshooting hard drive

2009-12-21T18:24:00.000-08:00

System does not recognize hard drive

The system can not boot from the hard drive from the A disk can not boot into the C drive, use the CMOS the automatic monitoring function can not be found in the presence of the hard disk. Most of these failures appear in the connecting cable or IDE port on the hard disk failure is unlikely in itself and can be re-plug hard drive cable or change IDE port and cable to replace the test, you'll quickly find fault lies. If the new hard drive is not connected to be accepted, a common reason is the master-slave jumpers on the hard disk, if an IDE hard disk online access two hard disk drives, it is necessary to distinguish the relationship between master and slave.

CMOS failure caused by

CMOS in the hard disk drive a direct impact on whether or not the correct type of normal use. The machines are now supported "IDE Auto Detect" function can automatically detect the hard disk type. When the hard disk type error, and sometimes simply can not start the system, and sometimes be able to start, but it will read and write error occurred. Such as CMOS, the type of hard drive is less than the actual hard disk capacity, then the hard drive behind the sector will not be able to read and write, if it is multi-regional state of the individual partitions will be lost. There is also a major cause of the malfunction, since the current logical arguments support the type of IDE hard disk can be used "Normal, LBA, Large", etc., if the normal mode, installed the data, but in the CMOS, replaced by other models , the hard drive read and write errors occur failure, because the mapping relationship has changed, and will not be able to read the original location of the correct hard drive.

Master boot program is causing the boot failure

Master boot program is located in the hard disk master boot sector, mainly used to test the correctness of the hard disk partitions, and to determine active partition, is responsible for guiding the activities of the right to be transferred to the DOS partition or other operating systems. This section will be unable to process damaged boot from the hard drive, but boot floppy or CD-ROM drive can read and write later. Ways to fix this fault is more simple, the use of high version of the DOS-FDISK the most convenient, as with parameters / mbr run-time will have a direct replacement (rewritable) hard disk master boot program. In fact the hard disk master boot sector is the establishment of this program, FDISK.EXE being a complete hard disk that contains the master boot program. While the DOS version of the constantly updated, but the hard disk master boot process has not changed from DOS 3.x to Windos 95 of the DOS, as long as to find a DOS boot disk to start the system and run this program can be repaired.

The partition table errors caused by failure to start

The hard disk partition table errors are serious errors, different errors might lead to different types of losses. If there is no active partition flag, then the computer does not start. However, after the boot floppy or CD-ROM drive can read and write, reset the active partition by FDISK to repair it.
If it is a partition type of error could result in the loss of a partition. The fourth partition table for the partition type byte value, the normal bootable DOS partition larger than 32MB of the basic value of 06, while the extended DOS partition value is 05. Many people take advantage of this type of value is to achieve a single partition encryption technology to restore the original values of the right type can make the partition back to normal.
There are other data in the partition table used to record the start or termination of the address partitions. These data will cause damage to the partition confusion or loss of, the available method is to use the backup partition table data to re-write back, or from other conditions the same type and the same partition on the hard disk partition table to obtain the data.
NU recovery tools such as software tools can be used, the operation very convenient. Of course, DEBUG can be used to operate, but the operation cumbersome and has certain risks.

How to backup files in windows xp

2009-10-30T21:01:00.000-07:00

Backup Method 1 – Image your install of windows xp, This is what I would recommend doing to backup windows xp.
Using a program called Norton ghost it is possible to take an entire copy of your system, this means if one day your windows xp wont boot you can fix this by loading the image of your system that you took before the error occurred. Norton ghost you will have to pay for, there are also free alternatives but I have not tried any out, search for them on google.
To take an image of your windows xp do the following. Install the ghost program, Next open the program and click on “Norton ghost boot wizard” select standard boot wizard > next, then no usb support (Im not to sure about this option, Even theo you select no usb support you can still use usb??) and click next. Select use pc dos and next. Dont enter any parameters and click next. Select your floppy drive then click next.
Dont have a floppy drive?? Then create a bootable usb stick or CD-ROM and make sure you copy the ghost.exe file to it. Now boot to the device and type in ghost.exe at the command prompt.
This will start the ghost program. Now in the menu select Local > Disk > To Image. Then select where you want to save the image. I would recommend saving to a separate hard-drive, CD-ROM or usb storage. Simply select the drive you want to save to, then down the bottom type in what file name you want to give it. Then click ok, Make sure you select high compression.
Now if you want to restore an image boot to the ghost program, Then select from the menu Local > Disk > From Image. Then browse to where you saved the image and click ok. The next screen will ask you how big you want your partitions, by default they will show as per what you had before you took the image, so you dont need to edit this setting just click next. Warning reloading an image will overwrite everything on your system, only do so if you are sure you need to.
Backup Method 2 - Use the built in windows xp backup program.
Step 1: Click Start -> All Programs -> Accessories -> System Tools -> Backup.
Step 2: Click Next in the first page and choose ‘Back up Files and Settings’ in the second page.
Step 3: Select “All information on this computer” click next
Step 4: Enter a location, I recommend using another media (Hard-disk, Tape drive) from what you are backing up. Give a good name for the backup like “System Backup 25 June 2008” so you can identify later exactly what the backup is. Click next.
Step 5: Click Finish
Backup Method 3 - Use XCOPY to backup files in windows xp.
Using xcopy it is possible to backup every file on your system but I do not recommend using this method as it can be a bit complicated and you are better off using the build in backup program for windows xp.
To access xcopy click on start > run > type in cmd and press enter. Now in the black window type in “xcopy /?” without the “. This will give you all the available options to you. You will need to run something like the following
xcopy C:\ D:\ /s /c /q /g /h /r /o /y
The C:\ drive is your source and the D:\ drive is the destination that you are backing up to. If possible I would recommend that the D: drive is a different physical disk. If you run the above command it will backup everything on your C: drive automatically, I would recommend running this command 2 or three times just to make sure all of your data has been backed up.

Tips for windows xp backups

2009-10-30T20:44:00.000-07:00

Here are a few tips on how you can have a successful and safe backup
1. Backup the files to a different media. For example if your files are stored on one hard-drive back them up to another hard-drive, because if you back them up to the same hard-drive and that hard drive fails you have lost all your data.
2. Backup files to more than one media, for example backup your files to another hard-disk then to a tape. If you have a years worth of backups on one hard-drive and that drive crashes you will lose all your years backups.
3. If your backups fail check the logs and find out why!! In my experience backups fail mostly because of corrupt files, run a check disk on the computer the files are on.
4. Test your backups, every now and then restore some data and check if all the files are there and that you can use them. The last thing you want to do is restore the files in an emergency and find out there is a problem.
5. Run regular backups, Every day if you can.
6. Make sure you have plenty of spare disk space to store your backups on.
7. Backing up to tape? Make sure you label your tapes correctly. And try not to put lots of backups on one tape, If that tape is faulty you could lose all your backups
8. Create a backup schedule and monitor it to make sure backups are finishing successfully and also on time.
9. How to access the built in windows xp backup package.
If you have Windows XP Professional, Backup utility is installed by default but in Windows XP Home it is not. However, Backup utility is provided with the CD.
Go to CD-ROM Drive:\VALUEADD\MSFT\NTBACKUP and double click Ntbackup.msi to start the Backup utility.
Follow this procedure to backup data using Backup utility:
Step 1: Click Start -> All Programs -> Accessories -> System Tools -> Backup.
Step 2: Click Next in the first page and choose ‘Back up Files and Settings’ in the second page.
Step 3: In the third page, you will be asked what to backup. If you have the habit of keeping all important files in your ‘My Documents’ folder and you want to backup only important files then choosing ‘My documents and settings’ would be more appropriate. Else if you want to manually choose the files and folders you want to backup, choose the option ‘Let me choose what to backup’.
Step 4: If you are manually choosing the folders, click all the folders you want to backup.
Step 5: On the next screen you will be asked to choose the backup type, Destination and Name. You won’t be using Tapes or Floppy Disks. You may select an external hard disk or another partition in the same hard disk. If the backup file size is small you may choose small portable pen drive such as USB hard drives.
Step 6: Windows XP does not support to write the backup file to a CD directly. So if you want to have the backup in a CD or DVD, create the backup file in the same hard disk and burn it in a CD or DVD.
If you have dedicated external hard disk for backup you can set a schedule to backup regularly. On the last page of backup utility before clicking Finish, Click Advanced -> When to Back up -> Later -> Set Schedule -> Schedule Job. Set the schedule and Click Ok.

What files do you need to backup in windows xp

2009-10-30T20:32:00.000-07:00

Backup System Files – I dont think its very important to backup the system files, As long as you take an “Image” of your system I think this is enough. But it is always a good idea to backup everything if you can just to be on the safe side.

Backup My Documents – By default when you click on file > save as in an application it will default to saving the files in your my documents. So it is very important to backup my documents as this is where all of your personal data will sit.

Backup E-mail Files – Backing up your emails is very important, None of us would like to loose all of our e-mails. Outlook .pst files (The file where all your e-mails are kept) are known for becoming corrupt quite frequently, Also when they get to 2gig in size there is a high chance they will get corrupt.

Backup Misc Data Files – You might have created a folder and keep files in there. If you have make sure you remember the location so we can back it up.

Backup System Registry – The windows xp system registry keeps all the information of your system, config / programs installed and so on. Sometimes you might go in to the registry and accidentally the wrong keys, or it is possible that the registry becomes corrupt.

Backup Desktop Icons – Do you save documents to your desktop?? If yes you will need to backup your desktop.

Track "0" is very important on your hard disk drive, the hard disk master boot record area (MBR). Track "0", once damaged, will severely damage the hard disk master boot program and partition table information, and the hard disk can not be boo. But we can use hard disk drive repair software DE (DiskEdit) to repair the track "0" damaged hard drive.

First download PCTools 9.0 to your local hard drive, because the file if very large in size, and can not be run in the FAT32 format hard drive, it would be better to burn it to a CD-ROM. Of course, if there is FAT16 formatted hard disk partition, PCTools can also be put on that partition.

Preparing a system boot floppy disk (or bootable CD-ROM), and put the boot disk into the floppy drive and restart the system (be sure to load the CD-ROM drive), and then insert the PCTools CD-ROM and enter the DE CD-ROM directory, then run the DE and enter the main interface, an information window will pop up to prompt DE run in read-only state. Press enter, the program prompts the user to select which file to open, just press enter to open the default document. After opening a document, press the Atl key to activate the function menu, select "Options (option) → Configuration (Configuration)" menu. Press Enter and enter the configuration window, use the "Tab" key to point the cursor onto the "Read Only" (read-only) option, and then press the space bar before the option "√" to disable it, finally press "OK" to Save your settings.

When return to the main interface, select "Select (select) → Drive (equipment)" menu, and then z list of drives appears, point the cursor to the "Physical" (physical disk), press the space bar to select it, then select the " Drives "(equipment) in column" Hard Disk "(hard disk) and press ENTER.

After return to the main interface, choose "Select → Partition Table (partition table)" menu, select and enter the hard disk partition table. If the hard disk has multiple partitions, then partition 1 is the C drive partition, the partition is started from the hard disk 0 cylinder. Now change the "Beginning Cylinder" (the starting cylinder) from 0 to 1.

After changes being made, press Enter, then the hard disk drive software will prompt asking whether to save the changes, select "Save" (Save) and press OK. Then you can press the Esc key to exit. Restart your computer, press the Del key to enter the BIOS settings, and it will automatically check BIOS hard drive settings, and you should be able to see the hard drive "Cylinder" (stigma) decreased 1 than the original, save and exit, re-partition, then format the hard drive, and the repair work is complete finished.

When the hard disk "0" track is damaged, the system self-test passes, but the startup partition C drive directory is lost or missing, a regular hard disk, "creak ... creak ..." sound continues, if you run SCANDISK to scan C disk, In the first cluster a red "B" appears; Fdisk can not find the hard disk, partitioning software such as the use of a low version of the DM partitioning, the program gets "dead" in the track 0; if you "Format C:" it prompts 0 track damaged or read command "Track 0 Bad". Then the DM needs to be used to repair the hard drive.

First of all downloaded the DM from the Internet and producing a good DM and boot the floppy, then run DM and the main interface appears. In the main interface, press Alt + M key to enter the advanced mode of DM, point the cursor on the "(E) dit / View partitions" (Edit / View partition) option, press the Enter key, the program select the hard drive that needs repair, select the hard disk, press enter, then it enters the hard disk partition view interface.

In the partition list box, select "1" partition, then the partition information will appears above the partition information bar, such as the partition format, capacity, start cylinder, end of the cylinder and so on. At this point in the cylinder begins to remember the "0" and the end of the cylinder number "2489." Keep the cursor on the 1st partition, and then press the Del key to delete the partition, select "Yes" and enter, the 1st partition will be deleted.

Keep your cursor on the No. 1 partition, and then press the Ins key to create the partition, select "DOS-FAT32" option for the partition type, press Enter and go to the critical step - "Select Entry Mode" (reference your volume model). Also be sure to select "(C) ylinders" (stigma) option after entering the capacity of input interfaces. In the interface, you have to enter the data according to the cylinder capacity. For the first partition (i.e. C drive), both cylinder start from it, but now we need to change the "0" to "1", as the back end of the cylinder number of the partition does not need to amended.

After re-set the partition 1, return to the partition interface, point the cursor to the "Save and Continue" (save and continue) option to save the settings, then press the Esc key to exit DM, finally you are prompted to restart your computer.

Restart the computer; first reset the hard disk parameters in the BIOS under the through "IDE HDD Auto-Detection", and format drive C. At this point, the repair is finished.

HDD Not Detected

When you run into the "HDD Not Detected" error, first check the external hard drive interface data lines to see if there is deformation, whether the connection spot have been incorrectly soldered joint. After doing that, remove the hard drive back, the circuit panels appears. Unscrew the control panel fixed screws; separate the main control panel from hard disk. Then you can see two of rows spring on the hard disk. One row is the main electrical power supply, and the other row is the magnetic head mechanical arm drive coil power source and circuit control board interface between the data transmission. For hard drives with no special package, you can often see the dust on spring plate and control circuit board. Dips the absorbent cotton into dehydrated alcohol and then clean the dust. Check the deformation part and remove the oxide layer. If the above treatment does not solve the problem, you have to open the main part of the hard disk. Go to a dusty-proof place, twist open the front hard drive screws (some fixed with adhesive). Remove the front cover, and then you will see the disk. First, use a digital multi-meter to test whether the head manipulator drive coil is open circuit, keeping mind that the normal coil resistance is about 20Ω. Second, check magnetic heads to make sure connection is disconnected.

Both sides of each disk have a head; each head has two connections on the arm receiving the head of integrated chip. The chip have a common model H1710Q, it transform the magnetic signals into electrical signals, and then sent the data to the circuit control panel processing. The head resistance should be between 23Ω ~ 26Ω. If higher, the head have been damaged. The head connects to the chip H1710Q, and H1710Q feet resistance is 1.7kΩ, if it’s 1.2kΩ or less then the chip has been breakdown, you may replace it together with the cable.

If the circuit connection on the head break, you can replace it with a∮ 0.2mm with high-quality enameled wire. Press one end of the metal shrapnel in the head, the other side of the welding is plated onto the corresponding H1710Q feet. Remember to stick the enameled wire in the arm of the corresponding slot, and use some 502 adhesive to prevent the hard disk rotation relative to the friction with the enameled wire. The various parts of the hard disk is restored, and finally use 702 silicone glue to sealed around the hard drive to prevent dust from entering. As the head size is very small, it’s not easy to stuck enameled wire in it, it is best to do it under the help of a magnifying glass.

How to backup important Files of Hard Disk C

2009-09-27T21:33:00.000-07:00

Currently, most Windows users install the system on the partition C, Windows will store all important system files and personal files on the C drive by default, which gives file security (in particular, is personal file security) bring greater risks. In order to avoid the harm C drive failure bring ,you should divide the hard disk into more than several partitions, doing a good job of other security measures (such as antivirus, Hacking, and data backup),while you could transfer important personal files to other Logical Disk from the default save location C disk.

1, My Documents Method 1: "cut" down "My Documents" folder from the C disk, "paste" it into other volumes,when the "Confirm File Transfer" dialog appear and ask you "Is it really want to move the system desktop.ini file? ", click" Yes "button,all documents were transferred to the designated locations. Method 2: In any position to create a new folder (eg D: \ My File), then right-click on the desktop "My Documents" icon on the shortcut menu, select "Properties", open the "My Documents Properties "dialog box, delete the" target folder "project" C: \ My Documents ", type" D: \ My File "can be, you do not delete the original" C: \ My Documents "folder.
Method 2: In any position create a new folder (eg D: \ My File), then right-click "My Documents" icon on the desktop,select "Properties" on the shortcut menu,open the "My Documents Properties "dialog box, delete the" target folder "project" C: \ My Documents ", type" D: \ My File ", you do not delete the original" C: \ My Documents "folder.

2, input method thesaurus Open the C: \ Windows folder, and cut the two files and paste them into any other volumes(such as E: \ My Ime).Then run the Registry Editor (regedit.exe), navigate to "HKEY_USERS \. DEFAULT \ Software \ Microsoft \ Windows \ CurrentVersion \ PINTLGNT" branch, the "User Define Phrase File" key data "C: \ Windows \ p * p.upt "changed to" E: \ My Ime \ p * p.upt ", the" Learning File "key data" C: \ Windows \ p * l.imd "changed to" E: \ My Ime \ p * l.imd ", you can enjoy these words of the long-term. Some input methods commonly used can not be transferred to other logical disk,then you have to manually backup in order to restore them in the event of a disaster.

3, e-mail Many users choose Outlook Express to handle their own messages. Its location is the default e-mail to save C: \ Windows \ ApplicationData \ Identities \ (B5C7FF60-A138-11D3-9317-A6D78FF47163) \ Microsoft \ Outlook Express, it can also be transferred.

4, Address Book Cutting down *. wab (* on behalf of Windows login user name) file which under C: \ Windows \ Application Data \ Microsoft \ Address Book,paste it into any other volumes(such as E : \ Mail), and then run the Registry Editor, navigate to "HKEY_CURRENT_USER \ Software \ Microsoft \ WAB \ WAB4 \ Wab File Name" branch of the "default" key data "C: \ Windows \ Application Data \ Microsoft \ Address Book \ *. wab "changed to" E: \ Mail \ *. wab ". Close the Registry Editor, you can use the address book in a new location.

5, the Favorites Windows favorites recorded the wonderful web page once visited,which allows you to speed up the browsing speed of the classic web pages. Open the C: \ Windows folder, you can see "Favorites" folder. Select this folder,"cut" down it to any other Logical disk folder (eg E: \ Bak) and "paste" it, you will see a "moving ... ..." dialog box, After the dialog box disappears,the transfer of success. Even after the reinstall the system, as long as the Registry Editor window, navigate to the "HKEY_USERS \. Default \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ User Shell Folders" branch of the "Favorites" key data "C: \ Windows \ Favorites \ "changed to" E: \ Bak \ Favorites \ ", your favorite exciting web pages can be re-used.

6, history record During operating the computer,your system will automatically record your operation to "History", which corresponds file is in C: \ Windows \ History.as moving "Favorites","cut and paste" it to any other volumes,this can guarantee your history is safe;The location of the history record in the registry is "C: \ Windows \ History \".The key is "History".

7, the network logon password During visiting Internet, there are many pages need to enter the registered user name and password,it will pop up a dialog box that prompts you just do not select "no longer save passwords" complex option after entered and confirmed, Windows will automatically remember the password, next time when you log on this page, you only need to enter the registered user name, the system will automatically fill in passwords. Windows will store the user name and password in the C: \ Windows \ Cookies folder. To cut and paste this folder to another Logical disk, and then modify the registry of the "Cookies" key (the same location with favorites and history records),no matter reinstall the system how many times,do not have to re-enter the visited web pages login password.

8, web cache folder Viewed a web page, the next time you can view this page offline, because when opening the web page,the browser has downloaded and saved this page to the specified folder in the cache.You can right-click the "Internet Explorer" icon the desktop,on the shortcut menu, select "Properties" to open "Internet Properties" dialog box,in the "General" tab,click the "Settings" button in the open "Settings" dialog box, click "Move Folder" button, open the "Browse for Folder" dialog box, in the local resource list, select a new folder, and then click the two "OK" in the "restart" dialog box, select "Yes", Windows automatically restarts to complete the transferring of the downloaded page.

The transfer of personal files is to move out of useful information,and no longer worry about C drive problems.Of course,transfer is not the most insurance way,because other the Logical disk except C drive is also not 100% insurance, risk still exists.Therefore,the best surefire plan is "file transfer + hard drive data backup."
