Disk drive fault detection and repair

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).

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.
