When I was a kid, me and my friend needed a blank disk. But we both didn't know the DOS commands to delete or format a disk. So we got an old disk from his dad and rubbed a magnet over it. After that we put it in the computer to see if it was empty. Turned out it was not and DuckTales the DOS game was on it. Still a good day !

Who the hell uses magnets? It may fall down and break, use pins!
