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.
Unless someone p[lans to employ NSA-grade electron-microscope track-edge detection on the media, overwriting it with zeros even once is very secure. Yes, you _can_ get edge bits and weak bits and all of that, but who is going to go to that much effort? Triple-wipe is plenty good enough for anything short of state secrets. -ethan
