    hammers and nails are just dangerous.
    fast and safest method is a pillar drill with eye protection and a dust mask.
    If anyone is going to the lengths of using any type of electron microscope to recover data after that they are welcome to it.
    It doesn't take long really, just have it DBAN over PXE, and do all the machines at once. Then just dispose afterwards.

    I seem to end up with a pile broken drives after they have been replaced.
    Good method if your chucking out an entire IT suite, but for a pile of disks the pillar drill method is much faster.

    Probably not an issue most of the time, but DBAN doesn't wipe data from bad sectors. hdparm on the other hand should if you follow these instructions (or use Parted Magic as shown below).

    Realistically, it doesn't matter - no-one is ever going to try to recover data from bad sectors of disposed of hard disks from a school...
