If that's what they told you, they sold you a load of shite. The forensic recovery techniques for hard drives rely on the mechanical and thermal drift of the heads (and therefore tracks) over time. It's highly unlikely that a series of writes in quick succession would drift enough to obliterate the excursions that a serious forensic data recovery effort (read government agency) is going to try to exploit. If you _really_ want to obliterate magnetic recordings, you need to blast them with nontrivial amounts of magnetic flux. If you're going to try to obliterate them yourself, you have to use the "obliterate" software multiple times _over_ _time_. TTYL, DougF KG4LMZ
