Okay I recently managed to get a few hard drives, what I really have been wanting to do is make a self dustructing drive. I have done some thinking about it, and I would perfef if the ammount of damage done was limited to the drive its self, so no gun powder or thermite. I was condering somthing like a electro mag that I could put inside the drive case to wipe the bastard.
Take plastic explosive, roll in hand (Like Play-Doh) until it becomes a thin roll, then remove top cover of hard drive (Don't forget to rig a detonator, and make sure u are in some sort of dust-free enviroment when u remove the cover), and apply around the outer edge of the inside of the drive. Also, drill a hole in the top cover, then seal with sillicone RTV gasket-maker from auto zone. By doing this, you create sort of a blow hole, when said plastic explosives are detonated. Or just get a fucking magnet. Assy Potato Lasers.
