Hmmm, it's that nagging question; quick format vs full format? full format vs low level format?.... Do you remember formatting your hard drive in DOS?... The Hard Drive, in it's IBM PC Compatible format has been with us since, what? 1980? Data in the early days was encoded using MFM, which was updated to RLL, but in that time, other things also changed. Like what Low Level Formatting actually meant. Because originally Low Level Format actually meant writing the sector boundaries to your disk. IDE hard drives rarely let you do this, and doing so may have actually damaged your drive. This video will explore why then you shouldn't low level format your hard disk drive.
