I’ve used this hard drive simulator in class countless times. It’s a great demonstration of how a typical magnetic hard drive operates and how they can fail. It’s such a mystery to most of us who don’t have old hard drives laying around the house to crack into to view the guts. Drive Savers has a hard drive simulator on their main web page. I discovered today that they provide the code to embed in your own site. So, what the heck, here you go.
