I pulled my hard drive from an old computer and tried to destroy it. I sat it on a cement car port, took a 6 foot long 1 inch thick steel bar with a chisel tip, and smashed, smashed, smashed! I could not break the hard drive! I bent it a little, but could not break it. Finally I threw it in a burn pile and “heat treated” it.
