That's what we were told when I was still with DOD. No number of overwrites made it impossible. No disk that ever contained classified information could ever be let out of containment. Other than melting them down the only method I ever heard of or saw that could truly erase a disk was passing them through the ship deguasser at the Navy Yard. And, after that the disk was not only clean, it was unusable. bill
