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 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).

Routine maintenance of the hard disk-2
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
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.

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.
