Disk Format

Disk formatting is the process of initializing and preparing your storage device like hard drive or flash drive to be recognized, read or written by computer. Before hard drive or any storage device is put to use, it must be formatted. This process also includes setting up of an empty file system, creating partitions or reorganizing the existing ones. All the hard disks should be formatted before use.

You can even format disks which are already in use. When you format these used disks / partitions, the system erases all the bookkeeping information of the disks, scans the entire disk to ensure the normal and reliable working of all the sectors. It also creates the internal address table to save data. In case, if the disk or drive contains the bad sectors, then all the bad sectors will be identified and marked. Formatting is suggested only when you are replacing your disk or when you install a new disk.
