    • Classification and causes of hard disk damage
    • Logical bad sectors of the hard disk is usually the cause of the majority is due to improper use or operation of the software, such as the often do not shut down properly (of course, frequent abnormal shutdown may also be caused by physical bad sectors). Logical bad sectors of the hard disk is a soft bad sectors, not really the physical damage, but if not promptly repair will lead to the spread of bad sectors area, resulting in more loss of data or program error. Repair bad sectors of the hard disk logic is very simple. In the previous version of Windows 98 operating system, we can take advantage of the system comes with ScanDisk to scan and check basically be able to solve the problem of the logical bad sectors. Because the the ScanDisk program can be used to check the disk physical medium, system files, directories, storage sector is damaged. The method I believe we should have more clearly, click Start - Programs - near - System Tools, and select the following ScanDisk can remember the choice should repair disk errors automatically spaces. In the version of Windows XP, the system itself is no longer to provide these functions. However, in order to prevent the mistake caused by the hard disk for errors, as long as the computer illegal restart or shut down illegal again to start the computer, the system will automatically run ScanDisk on the hard disk scan and check processing disk error, this time we must be patient wait for the program to run to completion automatically into the system, do not because of the waiting time is slightly longer directly press the Enter key to enter the system. This amount of hard disk generate long physical bad sectors, it is not worth the candle. , DiskGetor ScanDisk is found that the most commonly used tool for hard Logical bad sectors, I have to deal with the hard disk drive letter, select the "My Computer" and select Properties, select the "Tools" button " Error-checking status again in the "Scan Type" selected "comprehensive inspection" and "automatically fix errors" marked "hook", and then "Start" button. If the system startup disk scanning or can not enter the Windows system, we are also available to a floppy disk or CD-ROM boot disk computer, in the appropriate drive letter, such as "A:" run DiskGetor *: (Note: * To scan the hard disk drive letter), carriage return later on the corresponding need to scan the hard disk partition repair repairs. Next, we are speaking about the disk physical bad. To run ScanDisk in Windows 98, the report disk bad sectors on the hard drive or reinstall the system before advanced grid formatter run a progress to a halt last error can not be completed The formatting process, in this case it may be hard disk physical bad sectors. When this happens, we need to re judge, sometimes it may be some of the causes of the disk can not be normal scan or not function properly high-level format. I once encountered such a situation. Buy a new hard disk loading system Windows Xp installation disk comes formatted hard disk formatting operation, in any case can not be normal to complete the entire process, the progress bar to 87% after stops before then error, anxious so I worry a. Later get another machine as the disk is formatted using Windows disk management tools, they did not encounter such problems. Remind everyone here, not to say that the drive can not be used hard disk bad sectors, hard disk data above can still use just those bad sectors location data has been damaged, therefore, in our various operations previously, sure to save important data within the hard disk to another hard disk, so as not to cause the entire hard disk data loss after the operation was unsuccessful, you will lose it! ! ! In addition, unreadable data is very important to repair hard disk to the hard disk first aid center. Some friends check out the hard disk damage, if there is bad sectors does not affect the normal use of the hard disk, it is no longer processing and its consequences is further aggravating the situation of the bad sectors. Therefore, in the hard disk bad sectors, must cause us great.
    • Hard disk physical bad sectors repair
    • Our hard disk bad sectors, we can make use of some repair tools or software to repair bad sectors part also hidden, and then continue to use. First described here, such as physical bad sectors of the hard disk, even though it can be repaired, but its risk and can not be reduced to "0", still appears, therefore frequent data backup is necessary. In addition, some friends of the mistaken belief that a low-level formatting to repair physical bad sectors of the hard disk, like FOrmart command can not repair the logical bad sectors of the hard disk, the low-level formatting does not really solve the hard disk physical bad sectors on the hard disk. The so-called low-level formatting is blank disk divided into a cylinder, and track, then track divided into a number of sectors, each sector is divided Identification section ID spacer region GAP and data area DATA. The low-level format can only be completed in the DOS environment, but only for - hard drive and can not support a separate partition. Some bad tracks and bad sectors can fix by a low-level format, but for real physical hard disk surface scratches can not be repaired through a variety of methods, which only marked the location of bad sectors, so that the operating system do not use, to prevent the expansion of bad sectors and thus extend the hard disk to use. Particularly want to emphasize the low-level format is a lossy operation, a certain negative impact on the life of the hard drive, so if not necessary, users try not to low-level format the hard disk.
    • PS : If the above does not work , do not do irreversible operation should find a professional data recovery personnel or data recovery company to help otherwise cause data unrecoverable loss .
