DOD 5220-22M says: http://www.irwin.army.mil/ac/Electronic_Publications/DoD_Pubs/DoD%205220-22-M/cp 8.pdf Pages 14 and 15 note methods "a, b, d, and m" sanitizing fixed drives, and continues: d. Overwrite all addressable locations with a character, its complement, then a random character and verify. THIS METHOD IS NOT APPROVED FOR SANITIZING MEDIA THAT CONTAINS TOP SECRET INFORMA- TION. So 3 passes with verification is sufficient for up to Secret. Top Secret and higher classifications require physical destruction of the disk. (Note that these are the regs for civilian-sector contractors to the DoD, anybody with citations for the military and/or intelligence community segments feel free to speak up - but I suspect they're fairly similar..)
