How do you clean a drive without formatting?
I bought a second hand computer a few months ago and having heard some horror stories over the weekend concerning, wanted to ask how to ensure the integrity of the drives without formatting them (i.e, It was bought at a comp fair near Tottenham court rd and i dont know who had it before or what they had on the hard disk). I could format if that is my only option but that would be a real P.I.A.
Does anybody know any public domain programmes that are up to the job?
Thanks a lot.
