WinXP hard disk has bad sectors how to fix? How to repair bad sectors of the hard disk

In addition to the quality of the hard disk itself and the cause of aging, the bad sectors of the hard disk are largely caused by improper use. Of course, this bad track may be a software error, or it may be a hardware failure of the hard disk itself. How does the WinXP system hard disk have bad sectors? What is the method to repair the bad sectors of the WinXP system? Let me talk about the way WinXP repairs bad sectors of the hard disk.

The steps are as follows:

1. If your hard disk has the following symptoms, you should pay attention to whether the hard disk has bad sectors:

(1) When reading a file or running a program, the hard disk repeatedly reads the disk and makes an error, prompting the file to be corrupted, etc., or it takes a long time to succeed; sometimes even a blue screen appears;

(2) The sound of the hard disk suddenly changed from the normal friction sound to the strange sound;

(3) The system could not start normally when the virus infection was excluded, and the message “Sectornotfound” or “GeneralerrorinreadingdriveC” was displayed; Br>

(4) When the Format hard disk is stopped, it will not be completed until the end of a certain progress;

(5) Scandisk scan disk error will be automatically run every time the system is booted;

(6) When performing FDISK on the hard disk, it will go back and forth repeatedly to a certain progress;

(7) When booting, the system cannot be booted through the hard disk. After booting with a floppy disk, you can go to the hard disk drive letter. You can not enter, with the SYS command conduction system can not succeed. This situation is most likely caused by a problem with the boot sector of the hard disk.

Second, the repair method of bad sectors:

1, the repair of logical bad sectors

Under normal circumstances, the reason for the hard disk to generate logical bad sectors is that some genuine software will be in Some sectors on the hard disk write information, other software can not access this sector. In this case, the hard disk detection tool also mistakes the sector for bad sectors. Generally, this situation does not need to be repaired, but now Software is getting less and less of this encryption.

There is also a situation caused by improper use, such as the hard disk is unexpectedly restarted when reading data, it may cause logical bad sectors, and even serious physical bad sectors may occur. At this point, we can use the disk tool that comes with Windows to scan the hard disk and automatically fix the error.

The specific steps are as follows (take WinXP as an example), right click on the selected drive letter in my computer, and then select “Tools → Start Check & rdquo;; Br>

and select “Automatically fix file system errors" and <;Scan and restore bad sectors", and then click Start.

Scan times vary depending on disk capacity and scan options. However, it is worth noting that in Windows 98 or even the operating system, the details of each sector cannot be displayed, so usually in this case, we should choose the disk detection tool Scandisk under DOS. Scandisk will detect each sector and will flag bad sectors to prevent the operating system from continuing to access this area. Guaranteed system operation stability and data security.

Generally speaking, through the above method, the bad track on the hard disk still exists after the repair is completed, but it is marked, the system will not continue to access, but with the continued use of the hard disk, we may It is found that bad sectors of the hard disk may spread, so this method does not solve the problem fundamentally. A more appropriate method is to back up the hard disk data, and then re-partition and format the hard disk. Generally speaking, if the fault on the hard disk is only a logical bad track, the problem can be completely solved. Of course, it is recommended to use the Scandisk under DOS to detect the hard disk again after re-partitioning and formatting to ensure complete repair of the logical bad sectors of the hard disk.

2, the repair of physical bad sectors

If you follow the above steps to re-partition and format, and still find that the hard disk has bad sectors, then the hard disk is likely to have physical bad sectors. In fact, in this case, we do not have to rush to the conclusion that the bad sectors of the hard disk can be repaired. We can also use another software to low-level the hard disk, and perform re-partition formatting. Some hard disk bad sectors are also possible in this way. has been solved.

a, low-level formatted hard disk

There are two ways to lower the grid, one is through the low-level tool that comes with the BIOS of the motherboard, and the other is low-level by software. The method of the low-level tool that comes with the BIOS of the motherboard will be limited by the motherboard. Some motherboards are not equipped with such a program in the BIOS, and most of the new models of the motherboard do not have this low-level function, so it is recommended to use software. The way to perform low-level formatting of the hard disk.

Maxtor has produced a low-level tool low.exe. This software can lower the Maxtor hard disk. In fact, this program can be applied to various brands of IDE hard drives of various brands. The operation of the software is quite simple

After booting, press "Y” to enter the software, just select the hard disk that needs low grid, and then select the hard disk selected to start low."

The general low-level process is relatively long, so you need to wait patiently. In addition, one thing to remind the reader is that if you have other hard disks installed on your machine, it is best to remove the hard disk when running low low-level programs to avoid data loss.

b. Shielding physical bad sectors

If bad sectors are still found after the low grid, then there is a physical bad track on this hard disk. Since the physical bad sectors are usually caused by impact or sudden power failure during the use of the hard disk, when the disk rotates at a high speed, the magnetic head may hit the disk, causing damage to the magnetic medium, even if the disk detection software will be bad. The track mark, although the operating system will not continue to access this sector, but the physical bad sectors will usually spread after a period of use, because even after the bad track mark, the hard disk may still access the sectors around the bad track, thus Causes the spread of bad sectors. In order to avoid the spread of bad sectors, we better shield the bad sectors from an unused partition.

We can block bad sectors to an unused partition. You can use the software PQMagic. This software has DOS and Windows versions, but since we usually format the hard disk, we still find that there are still bad areas. Windows system is installed, so it is recommended to use the DOS version of PQMagic (with Chinese version).

Before using PQMagic for partitioning, we must first find the location of the bad track. We can scan the surface of the disk through Scandisk first, and then understand the general location of the bad track of the hard disk before we can determine the partitioning scheme. For example, if the hard disk bad track is about 20% in the C drive, we can use PQMagic to divide the front of the C drive on the hard disk by roughly 25%-30% of the space as a hidden partition. The specific operation method is as follows (because PQMagic under DOS is not convenient for screenshots, we will use Windows version as an example to demonstrate, the operation is similar), start PQMagic, click the right mouse button on the C drive icon in the graphical interface, select &ldquo ; Adjust capacity /move &

There will be a toolbar that can be pulled, we just need to move the C drive from the starting position of the hard disk. Below the pulled toolbar, there is also the capacity display of the free space before the start of the hard disk to the C drive.

For example, the capacity of the C drive is 10GB, we only need to adjust this free space to about 3GB. At this point, the capacity of the C drive becomes 7GB. In this process, it is recommended to select a slightly larger space for shielding, instead of squandering the lost capacity, so as not to divide the bad sectors into the space of the C drive. After all, the current hard drive is 80GB to 120GB, losing the capacity of several Gs in this area, but it is worthwhile to save a hard drive. After confirming and exiting, waiting for the PQMagic mobile partition, and then restarting, the bad sectors of the hard disk are already in the hidden partition, and the operating system cannot be accessed. The author used this method to successfully shield the bad sectors of an 80GB hard disk, and the use is still stable. (Note: It is recommended to scan the new partition after the bad track is blocked. It is still recommended to use Scandisk to ensure that the bad track has been completely shielded from the hidden partition. Of course, if you think it is a pity, you can also be in the bad track. Before creating a new partition, of course, the premise is not to divide the bad sectors into new partitions again, but it is not recommended to avoid too many partitions and too fragmented, which will greatly affect the disk performance.)

Of course, the method of masking partitions is only applicable to the situation where the bad sectors of the hard disk are concentrated. If the bad sectors of the hard disk are scattered, it is troublesome. It is recommended to replace the hard disk to ensure the stability of the system and the security of the data. The method of repair hard disk bad sectors WinXP

or more is small to give you details of. After a long period of use or improper use, we will inevitably have some problems, which is what we usually call "bad sectors". If you don't know how to fix it, please refer to the above method!
