Adam,

A while ago I read about a company in Denmark that recovers data from
damaged hard drives. They agreed to do a test for the NSA in wich the NSA
sent them a drive that was full of documents, but they formatted it, filled
the drive with zero's, formatted it again, filled the drive with one's, then
format some more, held a strong magnet over it for an extensive period of
time, and slammed four nails into it. The company could then retrieve 80% of
the original data. So yes, I do believe that 30 is not exaturated.

Check out these links, maybe these data recovery company sites can convince
you.

Greetings Folks,

I had an interesting conversation today with someone from FAST
(Federation
Against Software Theft) They pretend not to be a snitch wing of the BSA.
Anyway, to get to the point, the guy that came to see me said that their
forensics guys could read data off a hard drive that had been written
over
up to thirty times. I find this very hard to believe and told him I
thought
he was mistaken but the guy was adamant that it could be done. My
question
is, does anyone have any views on this, or, can anyone point me to a
source
of information where I can get the facts on exactly how much data can be
retrieved off a hard drive and under what conditions etc etc.

Thanks

Dave Adams
