Re: ultimate hard disk wipes I would worry that the physical media surface shape and properties are history dependent and readable (with technical effort) with a scanning tunneling atomic force microscope technology....
I think that the Curie point is a good start when 'they' are sneaking through (or busting down the door), perhaps use an 1100 watt microwave (careful about FCC emission regs here). Also thermite and magnesium may have weapons charge or possession problems in some jurisdictions.
I think that fusion (melting) or dissolution (acid or oxidizer) are safest for drop dead security. Run the microwave just a little longer, the hard drive is going to heat fast. Just how big and uninterruptable is that power supply?
Magnesium, microwave or thermite, do it in a fire protected area (concrete block). Don't let 'them' add arson to the list, much less torching your place over a little misunderstanding.
Good luck. Great business opportunities are in some really scary places with strange people who have interesting connections.
