+1. It may also erase things like reserved space and bad blocks that are
not visible via the block device and thus immune to shred.
ATA security erase is the fac

The hammer method is far more satisfying with glass platters. :)

You need to match the strength of the equipment to the media in use.
Modern hard disks need fairly strong fields to fully erase, and th

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 pro
