A sector is a subdivision of a track (a circular path on the surface of a disk) on your hard disk that stores a fixed amount of data. A bad sector is a sector that appears to be defective and it won't respond to read or write operations. There are two types of bad sectors:

Physical Bad Sector (Hard Bad Sectors)

As the name indicates, physical bad sectors are caused by physical damage on the hard disk. This type of bad sectors cannot be repaired using CHKDSK or any other tools. If you want to continue using a hard disk with physical bad sectors, what you can do is to use some third-party tool to block these sectors on the hard disk and prevent the system and programs from visiting them.

Logical Bad Sector (Soft Bad Sectors)

Unlike physical bad sectors, logical bad sectors generally result from software errors like a sudden shutdown of your computer and virus attacks. In most of the cases, the operating system will mark a sector as bad when they try to read data from the sector and find the error-correcting code doesn't match the contents of it. Fortunately, logical bad sectors can be repaired using CHKDSK.

How to Repair Bad Sectors on Hard Disk Permanently Using CMD

If you don't want to perform the disk checking and repairing process in CMD, you can choose to use the disk check feature, which works the same as CHKDSK.
