If data security is a concern, but we want to retain the media, then a three-pass overwrite with varying bit patterns may be the only viable option, as formatting may not clear the sectors. Of course, the only foolproof way to make sure the data is unrecoverable is to destroy the media.
I think there have been bounties out there for a while for anyone to recover data after a one pass wipe of a hard drive... and it's been unclaimed. My understanding is when you look below the "current data" there is supposedly a lot of noise and making out the prior data is very difficult. - Ethan
