Most defense contractor infosec departments will accept video evidence of HDD destruction so long as they do a walk through showing serial numbers so they know which drives are accounted for. As a result there's tons of videos that the public will never see of the world's heaviest presses, shears and brakes being used to decimate lines of hard drives. When you run a shipyard it's cheaper to just bend hard drives than it is to ship them back to HQ and have infosec deal with them. One of my jobs as an intern was to take a list of serial numbers and watch the video walk-through and confirm the list matched the drives.
