First time accepted submitter THE_WELL_HUNG_OYSTER writes "I have 10-15 old hard drives I want to trash, some IDE and some SATA. Even if I still had IDE hardware, I don't want to wait several weeks to run DBAN on all of them. I could use a degausser, but they are prohibitively expensive. I could send them to a data destruction firm, but can they be trusted? What's the fastest, cheapest DIY solution?"
