WinXP system hard drive has bad way how to fix?

   The steps are as follows:

  First, if you have the following symptoms of the hard drive, you should pay attention to the hard drive has been a bad way:

(1) Read a file or run a program, the hard disk repeatedly read the disk and error, prompting file damage information, or to be successful after a long time, sometimes even a blue screen;

(2) The hard disk sound suddenly from the original normal friction sound into a strange sound;

(3) In the case of excluding virus infection, the system can not start normally, appear "Sectornotfound" or "Generalerrorinreadingdrivec" and other prompt information;

(4) Format hard disk, to a certain progress stopped before, the last error, can not be completed;

(5) Every time the system boot will automatically run ScanDisk scan disk error;

(6) to the hard drive to perform fdisk, to a certain progress will be repeated into retreat;

(7) boot can not be through the hard disk boot system, with a floppy disk may be turned to the hard drive letter, but unable to enter, with the SYS command conduction system can not be successful. This is most likely the problem with the boot sector of the hard drive.

  Second, the bad Road repair method:

  1, the restoration of the logical bad Road

Under normal circumstances, hard drive logical bad reason is that some genuine software will be in some sectors of the hard disk to write information, other software can not access this sector, in this case, the hard disk detection tool will also mistakenly think that the sector produced a bad, generally this situation does not need to repair, But today's software is less used in this way of encryption.

Another situation is the use of improper causes, such as the hard disk in the reading of data accidentally restarted, it is possible to produce logical bad, the situation will even produce a serious physical bad way. We can use the disk tool with Windows to scan the hard disk at this time and fix the errors automatically.

The specific steps are as follows (take WinXP as an example), click the right mouse button in My Computer, select "tools → start checking" in the pop-up drive Properties window;

and select "Fix file system errors automatically" and "scan and recover bad sectors", then click Start.

The scan time varies depending on disk capacity and scanning options. It is worth noting, however, that in Windows98 or even above operating systems, the details of each sector are not shown, so it is often preferable to choose DOS Disk Detection Tool ScanDisk in this case. ScanDisk detects each sector and marks bad sectors so that the operating system continues to access the area. Ensure the stability of the system and the security of the data.

In general, through the above method, after the repair is completed, the hard drive on the bad road still exist, just do the tag, the system will not continue to visit, but as the hard drive continues to use, we may find that the hard drive bad road spread, so this method does not fundamentally solve the problem. The better way is to backup the hard disk data, and then repartition format the hard disk, in general, if the failure of the hard drive is only logical bad way, you can completely solve the problem. Of course, it is recommended that after the partition and format, use the DOS ScanDisk again to detect the hard drive, to ensure that the hard drive logic bad road full repair.

  2, the physical bad road repair

If you follow the steps above to reformat, you still find that the hard drive has bad, then the hard drive is likely to have a physical bad way. In fact, in this case, we do not have to rush to the hard drive bad road can be repaired to the conclusion that another software can be used to lower the hard disk, in the repartition format, some hard drive bad way may be solved by this way.

  A, low-level formatted hard disk

There are two ways to lower the grid, one is the low grid tool with the motherboard BIOS, and the other is to use the software to lower the grid. The method of using the low grid tool with the motherboard BIOS will be limited by the motherboard, some motherboards are not equipped with such a program in the BIOS, and most of the new model of the motherboard is not the function of the low grid, so the recommended or software to the way to the low-level format of the hard disk.

Maxtor produced a low grid tool Low.exe, the software can be maxtor hard disk, in fact, this program can be applied to various brands of various models of IDE hard disk. The operation of the software is quite simple

After startup, press "Y" to enter the software, just select the hard drive that you need to lower the grid, and then select the hard drive on which to start the low grid selection.

The general low lattice process is longer, so it takes patience to wait. Also, it is important to remind the reader that if you have other hard drives installed on your machine, it is best to remove the hard drive when running the low Low-pass program to avoid data loss.

  B, shielding physical bad road

If the low lattice still finds a bad path, then almost certainly there is a physical bad on the hard drive. Because the physical bad road is usually caused by the impact of hard disk use or sudden power loss, etc., in the disc high-speed rotation, the head may impact the disc, resulting in magnetic media damage formed, even through the disk detection software will be bad marks, the operating system does not continue to access this sector, But the physical bad usually spreads after a period of time, due to the fact that the hard drive may still be able to access the sectors around the bad track, causing the spread of the bad road. To avoid the spread of the bad, we'd better shield the bad to an unused partition.

We block the bad way to an unused partition, you can use the software pqmagic, this software has DOS and Windows version, but because we usually format the hard disk and found that there are still bad areas, and there is no Windows system installed, so the recommended use of the DOS version of the Pqmagic (with Chinese version).

Before using Pqmagic for partitioning, we first need to find the location of the bad track. We can first through the ScanDisk for the disk surface scanning, the hard drive of the rough path to understand the approximate location, to determine the partition scheme. For example, hard drive bad road in about 20% in the C disk, we can use Pqmagic to the hard drive in the front of C disk roughly 25%-30% of the space zoned as a hidden partition. The specific operation method is as follows (because of DOS pqmagic not convenient screenshot, we take the version of Windows as an example to demonstrate, the operation is similar), start Pqmagic, in the graphical interface in the C-disk icon Click on the right mouse button, select "Adjust Capacity/move"

There will be a pull bar, we just have to move the C disk from the start of the hard drive. The capacity of the free space before the C disk is also shown below the pull bar and the starting position of the hard drive

For example, C disk capacity of 10GB, we just have to adjust this free space to 3GB or so, at this point, the capacity of C disk will become 7GB. In this process, it is recommended to choose a slightly larger shielding space, rather than the loss of the capacity to be divided, so as not to still divide the bad way in the C disk space. After all, now the hard disk is 80GB to 120GB, lost this just a few G capacity but can save a hard drive is still worthwhile. After you are sure to exit, wait for the pqmagic to move the partition, and then reboot, the hard drive is already in the hidden partition and the operating system cannot access it. The author adopts this method to successfully shield a 80GB hard disk from the bad track, so it is still stable to use. (Note: It is recommended that a new partition be scanned after the bad block is completed, and ScanDisk is still recommended to ensure that the bad path is completely masked to the hidden partition.) Of course, if you feel pity, you can also set up a new partition before the bad way, of course, the premise is not to divide the bad way into the new partition again, but do not recommend this, lest partition too much and too fragmented, will greatly affect disk performance. )

Of course, shielding partition This method only applies with hard drive bad road more concentrated situation, if the hard drive bad way more dispersed on the more trouble, it is recommended to replace the hard drive to ensure the stability of the system and data security.
