Re: What is the universal (world wide) understanding behind degaussing harddisks?
Degaussing a hard drive will render it inoperative. It's also relatively
hard to do/requires special equipment. (Just waving a refrigerator
magnet around isn't going to do it.) Degaussing should be understood as
a final step before discarding equipment. (And, for what it's worth,
it's not a process I generally favor because it's hard to verify that
the data on the disk has actually been erased; in most cases I'd
recommend physical destruction over degaussing.)
