Hard disk shields bad sectors and bad sectors for several issues

If you use the advanced formatting function or automatic scanning and repair function of the hard disk, it should be a logical bad sector after repair, and if it is not a physical bad sector, it is a physical bad sector

There are generally two ways to deal with bad sectors in hard disks1, isolate the bad sectors with software, and hide them from access This method is simple but will lose capacity 2 Replace the bad sectors with the method of replacing sectors The hard disk has a part of the good sectors left in the factory to replace the bad sectors in use But the specific excitation conditions and software that need to be replaced This does not need to hide and lose sectors and capacity MHDD has this function

Logical bad sectors can be repaired, physical bad sectors are very difficult, generally low-level hard disk, the risk is relatively large, if the logical bad sectors, with the system's own tools can be repaired, if it can't be repaired, I think your hard disk is in the product of warranty, you can take the warranty, this is the best way.

Change the hard drive, don't want to blue screen next time to put important files in the loss of the smart way to think that that's it.

1. First turn on the computer, then find the bad sector disk that needs to be repaired, right-click and select "Properties", as shown in the figure below.

2. Then in the properties window that opens, select "Tools", and then continue to select "Start Check"; Please refer to the figure below for details.

3. Then in the repair interface that pops up, select "Scan and Recover Sectors", here you can remove the automatic repair of file system errors, as shown in the figure below.

4. Then click on the Start option in the window, as shown in the image below.

5. During the repair process, the larger the disk, the more time will be wasted, you can choose the evening or other free time, hang in the background, and repair it slowly.

I prefer to use hddreg to fix it.,It's relatively simple.,Shielding.,I'm just estimating how many g he's on the disk.,And then the partition will put him in.,Don't give her the drive letter in the operating system or partition software.,So it won't be accessed.。

Can't fix it.,You can only scan the location of the bad track after recording.,Isolate that part when partitioning.,It's recommended to change it.。

Generally speaking, bad sectors on the hard disk cannot be repaired. However, bad sector detection can be used.

You can use the domestic hard disk partition repair software DiskGenius

Here are very detailed steps, you can check out this article: how to shield the bad sectors of the mobile hard disk, how to fix the bad sectors of the hard disk.

The more professional approach is: first use software to scan out the bad track, estimate the location of the bad track, and then use partition software to divide the area where the bad track is located, hide it, and do not use it.

There are two kinds of bad sectors, one is logical, the other is physical, logical bad sectors can be solved by disk scanning of tools provided by the system, physical bad sectors are generally scanned by the command scandisk under pure dos, but it is very slow, there are some tools that can, you have to find it yourself. Once the location of the bad sectors is determined, for example, the first few clusters, then divide the 2G partition in front and hide it, this generally uses the PQMoster software, and the physical bad sectors will expand like an avalanche, if you don't want to have a loss, don't toss too much on a hard disk.
