How does MCR destroy Hard drive data?
When the computer is operable we use a program that performs a 3 pass write to every byte on the drive in accordance with US Department of Defense 5220.22M standard. If the computer is not working but the drive is we have equipment that performs this procedure on bare drives. In cases where the drive is not operating or has a nonstandard interface, we dismantle the drive, magnetically erase the platters, cut the platters in to pieces and have them smelted.
