If the Short Wipe meets the standard, why does EraserDisk also have a Long Wipe with Format?
A. Most agencies that deal with Secret or Top Secret information have their own internal standards that are more strict than DoD 5520.22-M, but these standards are not publicly issued. As far as we know, the Long Wipe with Format meets every agency’s standards for drive sterilization, although some organizations also require the platters to be physically damaged after they have been sterilized. You’ll need to supply your own hammer for that step.
