Assunto: OT Hard drive info
I saw a site a while ago that had a pretty indepth information about
hard drives history, how they work, and forensics. I'm looking for a
site to show people to prove that any information deleted off a hard
drive within the OS actually never leaves the hard drive and forensics
experts can retreive data from it.

Anyone know of any such information?
