Back in the 80's I worked with a certain MoD contractor and their way of ensuring data was not retrievable from dead hard disks (mostly DEC RA81's) was to:
- write destructive data patterns across the platters, then
- put the disk through a large coil which generated an extremely strong magnetic field, then
- physically crush the disk drive, then
- put the crushed drive in secure offsite storage - forever.
For all I know there may still be a room full of them under lock and key. The project requirements normally required stable hardware specs for 30 years! Since no hardware manufacturer can commit to that, MoD had to buy 30 years worth of spare parts up front - nice little earner for the hardware suppliers!
I guess I'm up the high end of PC requirements so I just ordered one of these to get more speed from my main machine:
