ItcheSrulik, I didn’t know that laser scanners have magnets, but who cares? The problem with using a magnet is that you never know whether or not you have been successful.
watermelon, when we say “destroy” a drive, we mean exactly that. Discarding a drive in the trash changes nothing.
Inside a hard drive are one or more disks called “platters.” It is these items to which the data is written. Some people have them cut up or have holes drilled into them. The method I once heard about that most impressed me involved melting them down.
If you should wipe a drive with DBAN, you can always keep it until you find someone who can destroy it. It’s not like it takes up a lot of space.
