[kwlug-disc] OT - degauss/wipe a dead hard drive/LTO tapes

The magnetic field has to be moved in close proximity.  The easiest way is to pass an alternating through it.  The other, of course, is moving the magnet physically which becomes more difficult as the size of the magnet increases and the space in which to move it decreases.  This assumes relatively easy access.

It's also fun to take apart things and good for the kids.

As for degaussing, you'll find two very strong magnets in every drive you take apart. Use one to pin a Linux Journal onto the fridge. Seems just putting strong magnets next to a disk won't affect the data on it.
