How scan disk bad sectors

Users questions:
Experts answer: As the hard working environment within the very strict requirements, little dust inside the hard disk can also cause irreparable damage, so when the hard disk bad sectors, we also should not open the hard disk for maintenance, only through a number of tools for software to carry out repair to restore the maximum loss Loss. When we determine the hard disk has bad sectors, we also can not determine the damage that bad sectors in the end is a logical or physical injury, we have only to follow the steps from simple to complex repairs, the general logical bad sectors through a simple software fix can solve the fault , but some physical bad sectors but it needs further revision Hard drive data recovery to ensure the safety and proper use. Logical bad sectors repair under normal circumstances, produce logical bad sectors hard because some of legitimate software on your hard disk write information to certain sectors, while other software can not access this sector, in which case, the hard disk Jiancegongju mistaken for the sector will generate The bad sectors, generally do not need to fix this situation, but now fewer and fewer software encryption method of using this. Another case is caused by improper use, for example hard disk to read data in the accident was restart, there may have logical bad sectors, in serious cases even cause physical bad sectors. I We now can use Windows built-in hard disk tools to scan and automatically fix the error. Concrete steps are as follows (in WindowsXP for example), select the drive letter on my computer and click the right mouse button pop-up drive in the Properties window, select "Tools Start checking "and select" Automatically fix file system errors "and" scan and recovery of bad sectors "and then click Start (Figure tool-1.gif), scan time and scan for disk capacity varies options . but is worth noting that even more than in Windows98 Operating system and can not show the details of each sector, so often in this case, we select the best detection tools disk under DOS Scandisk. Scandisk will check every sector, and will mark bad sectors, so that the operating system to access this area. Guarantee the stability of system operation and data security. In general, by the way, after the completion of repair bad sectors on your hard disk is still there but cook the tag, the system will not continue to visit, but as the continued use of the hard disk, we may find hard disk damage may proliferation, so this side France does not fundamentally solve the problem. More appropriate approach is to back up data on the hard drive and then re-format the hard disk partition, in general, only if the hard disk failure is a logical bad sectors, it can completely solve the problem. Of course, the recommended course of re-partitioned and formatted, use the DOS, On the hard disk damage can repair a conclusion, you can also use other software on the hard drive of a low-grid, making re-format the partition, and some hard disk damage may also be resolved this way. Low-level format the hard way, there are two low-grid, a motherboard BIOS that comes through the lower grid tools One is the way with a low grid software. Through the motherboard BIOS tool comes with a low grid method will be restrictions on the motherboard, the BIOS of some motherboards and not equipped with such programs, and now most new models of motherboards do not have the low-cell function, so recommend, or use software square Type to carry out low-level hard disk format. Maxtor had produced a low-grid tool low.exe, the software can be low Maxtor hard disk format, in fact, this procedure can be applied to various models of various brands of IDE drives. Operation of the software is simple to start after the press "Y "Into the software, simply select a low lattice of hard disks, and then select the lower box select the hard drive started on it. The general format of the process is relatively low long, so they need patience. In addition, the need to remind the reader of the point is, if Your machine is also equipped with other hard drive is running low this low cell process When this sequence is best to remove the hard drive to avoid data loss. Physical bad sectors if the shield is still found after the low lattice bad sectors, it is almost certain that there are physical bad sectors on the hard disk has. As is usually due to the hard disk physical bad sectors suffered a crash or sudden use of power generated, etc., in the high-speed disc
