How to repair hard drive bad sectors

The hard drive is one of the most important storage devices in the computer, and the bad sectors problem is a common hardware failure. Bad sectors refer to physical damage or electrical failure in the storage units on the hard disk, resulting in data being unable to be read or written correctly. The occurrence of bad sectors on the hard drive may lead to the loss of important data, so repairing bad sectors on the hard drive is a skill that every user should master.

During the formatting process, the system will reallocate the storage units of the hard disk so that bad sectors are marked and no longer used.
