  1. When I worked IT at a 2 year college, they did the 3 pass wipe of the drives. This is due to they often get reused in computers sent to surplus as boot boxes only, no OS or anything, just a wiped drive. For computers not heading to either scrap or surplus, wiped drives may be put in and then reimaged for use for another employee. This is most likely to not just a single format, but may add in a random character(s) as well so NO critical info can be found on the drives, once the computer leaves the campus for surplus. Similar is done when a drive is to be disposed of, drill or hammer the drive so it can't be used, especially if it no longer works (at that time, 2 or so years ago, mechanical drives were still in use). I think these days if SSD drives are used, they just break them when they are to be disposed of, or as said, they do the full wipe and then sell the surplus PC/laptop with an empty SSD.
