If for some reason you want to completely destroy a hard drive—like when there’s sensitive or proprietary information on your computer—you definitely can. Keep in mind that it will involve physically removing the hard drive, so use an online tutorial specific to your computer for best results. Then open the hard drive casing, remove the magnets and plate, and destroy every piece the old-fashioned way: by bashing it with a hammer or drilling holes through it. You’ll have data security, and you might even have fun with that last step.
