A hard drive or SSD of any make or brand is divided into millions of sectors. These sectors (or blocks) on the drives are nothing but small spaces which stores our data. Bad sectors may arouse due to any physical damage received, e.g. the head of the drive making contact with the hard disk drive Platter causing shocks and vibrations. Once the drive develops some bad sectors, they (bad sectors) cannot be accessed due to damage received on the surface of the disk drive. A bad sector of a hard drive is of no use for storing any piece of data or information on it.
Why are bad sectors a nightmare?
