After you open the HD case (not on a drive you're concerned about),
check out the arm, there's a very powerful set of magnets *in* the
case. I don't see how a set of magnets that close to a hard drive
would do no damage, but a student using a magnet *could* damage it.

I agree. I would think the magnet would just randomize the bits and
make it totally unusable until you did a format.
