DATA Error

What do you do with old hard drives? I have no idea what is "accessible" on this one. Could be anything. It actually stopped working some time ago, but couldn't some guru hook it up to a car battery and a celery stick and download our life's history??? I don't know. But really, who's going to even try? After I took the cover off and scratched it up a bit, I'm not sure anyone's going to think there's a chance of it actually working. Even with a celery stalk...
