There's a problem with that too. Advanced recovery services probably can still retrieve some data from a HDD with 2 holes in it. What's probably desired for total data wiping is a combination of overwriting, magnetic erasure(degausser) and then physical destruction (incinerator sounds like the best one so far).
But that's probably going overboard for 98% of the world. @llen On Fri, 29 Mar 2002, Mark Medici wrote: > I don't know how many disks Dan needs to erase.
