geetha4u: when we purchase a new computer the very first thing is we format it, what is the reason?
A brand new hard drive cannot be used until it has been formatted. Formatting places magnetic markers on the drive surface to define the sectors in which data is stored. When you format a hard drive, you erase all its files and prepare it as if it were a new or blank hard dive. Formatting your hard drive will wipe clean your drive just like a new hard drive.
