New Zealand Information Security Manual (NZISM) 13.4.13.C.01: Overwrite passes for non-volatile magnetic media

What does 13.4.13.C.01 require?

Agencies must sanitise non-volatile magnetic media as follows: for media made before 2001 or smaller than 15GB, overwrite the entire media at least three times with an arbitrary pattern and then read back to verify; for media made after 2001 or larger than 15GB, overwrite the entire media at least once with an arbitrary pattern and then read back to verify.
