I dunno? I was kidding. Never actually done it. But I know a guy, who has a friend, whos cousins dentist claims that it simply scrambles the data but does nothing to harm the disks from being re-written to again. So if your willing to believe this dentist, give it a shot.
Seriously I know a guy who says he does this all the time … but he’s a bit of a nut job. :crazy:
