"This is Richard Goms and we are in Salt Lake City, Utah and we are talking about hard drive basics. Right now I'm going to talk to you about how to destroy a hard drive. There may be times when you have sensitive data or data you don't want anybody else to know about and you want to physically destroy the hard drive so that it is completely unrecoverable. There are a number of ways of doing this. One way is to have some special equipment and buy some hydrochloric acid and soak the hard drive in hydrochloric acid until it has practically completely dissolved. Another way of destroying the hard drive is to put the hard drive in a vice and either grind it with power tools down until it is just a powder or drill holes through the drive and through the plates and that would of course permanently destroy the hard drive and make the data unrecoverable. A third way of destroying the hard drive would be to remove the cover either with a hammer or something else and take the individual plates out, put them in a vice, use a hacksaw and cut the plates into small pieces. A fourth method of destroying the hard drive would be to take it to a company that has special magnetic equipment called Degossing Equipment that would scramble the magnetic material on the drive."
