Generally, if a physical fault occurs on the hard disk, it is difficult to fix it. The only thing you can do is change the disk. However, there is still a last method worth trying before the change, that is, low-level formatting.
Low-level formatting divides blank tiles into concentric circles and channels with different radius. It also divides the channels into several sectors with a capacity of 512 bytes. It should be noted here that low-level formatting is a high-loss operation on the hard disk, which will greatly shorten the hard disk service life. Therefore, it is recommended that you do not perform low-level formatting unless necessary.

In the past, there were two ways to perform low-level formatting: One is through the features supported by the motherboard BIOS, but the current motherboard generally does not have a secondary feature. Or use special software. DM is one of them.

By default, low-level formatting is not allowed when DM is started. You need to open the advanced menu of DM. You can add the parameter "dm/M" at startup or press "Alt + M" on the main interface of DM to switch to the advanced menu.

Select (m) aintenance options in the menu to go to the advanced menu.

Then select "(u) tilities" to enter the low-level formatting interface.


Next, select the hard disk that requires low-level formatting. If you only have one hard disk, press Enter. If you have multiple hard disks, select them.


Select the hard disk, and then select "low level format" for low-level formatting.

This is a warning window that will pop up. You need to press "Alt + C" for confirmation.

After confirmation, a window is displayed for you to confirm again. Select "yes ".


After the selection is complete, the low-level formatting of the hard disk starts. The progress is displayed in percentage.

Low-level formatting is time-consuming. It depends on the size of your hard disk and the damage to the hard disk.

Remind everyone that low-level formatting is a corrupt operation on the hard disk, not a last resort.
