There are two types of broken sectors. Physical broken sectors are hard disk space that is physically damaged. The head of the hard disk could come into contact with a moving pancake or moisture and dust got into the disk. Broken sectors of this type cannot be fixed.
Logical broken sectors are hard disk space that does not work properly. The operating system, trying to read data from such a bit sector, receives an adjustment error code. This means that something went wrong.
Such sectors are marked as damaged and Windows no longer uses them to store information. However, such sections can be restored by overwriting the disk with zeros (so-called low-level formatting).
For this:
The program will check your hard drive for broken sectors, mark sectors with physical damage as bad and fix sectors with logical errors, making them available for further use.
