[COLUG] Clearing your data from an HDD (was Re: Drive Wiping Speed)

Ummm some more:

"Looking at this from the other point of view, with the ever-increasing
data density on disk platters and a corresponding reduction in feature
size and use of exotic techniques to record data on the medium, it's
unlikely that anything can be recovered from any recent drive except
perhaps a single level via basic error-cancelling techniques. In
particular the the drives in use at the time that this paper was
originally written have mostly fallen out of use, so the methods that
applied specifically to the older, lower-density technology don't apply
any more. Conversely, with modern high-density drives, even if you've
got 10KB of sensitive data on a drive and can't erase it with 100%
certainty, the chances of an adversary being able to find the erased
traces of that 10KB in 80GB of other erased traces are close to zero."
