Big companies use electro magnets to erase hard drive data. The data on the drive is magnetic coding. Putting one on your Mac will most likely erase portions of your data. The best thing to do is try to back up your important data, then reformat and erase the drive by zeroing it out and then reinstalling the system. If you have any doubts about doing this take it to you local repairman for help.
