The disk object or file is wiped using the Bruce Schneier(7) algorithm. This algorithm is very secure, but very slow. Provides high-grade data wiping filling the unused space or file with a special digital pattern through 7 passes. The disk object or file is wiped using Department of Defense standard 5200.28-STD(7). Provides high-grade data wiping filling the unused space or file with a special digital pattern through 3 passes This algorithm is very secure, but slow. The disk object or file is wiped using Department of Defense standard 5220.22-M(3). A slower but little bit more secure algorithm than theĪlgorithm and it also conceals to some degree the fact that the disk or file has been wiped. The disk object or file is filled with pseudo-random numbers through 1 pass. Also it does not conceal the fact that the disk or file has been wiped. The fastest but the least secure algorithm. The disk object or file is filled with zeroes through 1 pass.

As the paper says, “ A good scrubbing with random data will do about as well as can be expected“. For any modern PRML/EPRML drive, a few passes of random scrubbing is the best you can do. If you’re using a drive which uses encoding technology X, you only need to perform the passes specific to X, and you never need to perform all 35 passes.

“In the time since this paper was published, some people have treated the 35-pass overwrite technique described in it more as a kind of voodoo incantation to banish evil spirits than the result of a technical analysis of drive encoding techniques… In fact performing the full 35-pass overwrite is pointless for any drive since it targets a blend of scenarios involving all types of (normally-used) encoding technology, which covers everything back to 30+-year-old MFM methods (if you don’t understand that statement, re-read the paper).
