You also must posit the data being valuable enough to such opponents for them to be willing to *spend* that much to get it. I'm quite confident that none of mine is. > ...this task proves to be more arduous (if not nigh on impossible) > than the destruction itself. Heating the disks to well above the Curie point of the magnetic coating is guaranteed to destroy all the data. That's much easier than running it through a National Magnet Lab sized magnet, especially since if they are aluminum they will melt. Glass ones are easily smashed, of course. > I took a hammer once to an old hard drive; frankly, I don't know whether > I killed it or not.

The cases come apart quite easily and yield useful parts such as rare-earth magnets. I'm quite certain that I could destroy one with a ten-pound sledgehammer, though. -- John Hasler jhas...@newsguy.com Elmwood, WI USA
