There have been articles written about this. It seems you can never completely delete data stored on hard drives, they claim it is always possible to recover it using magnetic inference analysis of the drive,
But NOBODY has ever publicly demonstrated it beyond a SINGLE overwrite, and even in those cases they were trying to recover a TINY segment of KNOWN content. (They knew what it used to say).
Its an urban myth.
Urban myth or not, it's great fun imagining the kinds of Area 51 tools they're using to protect national security. On that track (pardon the pun,) it probably doesn't matter how many times you overwrite it -- they just time-warp back in a UFO and image the original data while you're asleep <g> - Carl
