What’s a bad sector?
A hard drive contains millions of sectors. Once a sector is damaged, the data on it can’t be read and you are unable to write on it. As to bad sectors, there are two kinds, one is physically bad and one is logically bad. If physically bad, it is unrepairable unless you replace it with a new disk. Otherwise, it can be repaired, and we will be teaching you how to fix bad sectors that are damaged logically. Bad sectors can cause data loss on your hard drive. Thus, make sure that you do have backed up the data written on the sector before you take repairing steps, and stop your computer to continue writing on it.
