Depends how erased you want the media. If the magnetic field isn't strong
enough, you can still recover data from it, even after it's supposedly been
erased. I saw a paper once where the government did a test to see just what
it took to *totally* wipe a HD, and the magnetic field needed to do so was
so strong that it physically warped the platters.
