Ive been thinking lately on ways to totally clean a hard disk to hide files or information. I know that you can download programs to do this that just dump meaningless information into the drive to cover up what was previously there. But does this really work good and provide an efficient method of covering up things? not that i have anything to hide but i bought a laptop from my dads company for $75 bucks, a pII 533 128mb pc133 22gb hd prettey decent, and they didnt even format the hd! I told my dad about that and they are looking into ways of taking care of this, i told him that formating doenst really work so is this a viable soloution?
