That's what a sanitize operation does. It forgets the key and reformats the

Yes, but the devil is in the details. For example, for the SSD case, it is necessary
verify that the flash block that previously held the key information has been explicitly
erased (successfully) and not merely put on the free list. That's a detail I once
pried out of a manufacturer, insisting they were required to answer in order to get the
