This was my preferred secure wipe method when I still worked in I.T. My second career as a chemist is a much better fit.

  1. Remove drive from case.
  2. Place drive on concrete, gravel, sand or other non-flammable surface away from flammable objects/material. (I prefer to place the drive on an upside-down cast iron skillet so that the heat is less likely to damage the pavement.)
  3. Place ceramic flower pot with drain hole on top of drive (alternately, shotgun a can of soda, cut the top off, place this on top of drive).
  4. Fill pot/can with a thoroughly homogenized mix of iron oxide powder and aluminum powder. Do not breath this dust. The proper ratio is roughly 3:1 iron to aluminum by weight.
  5. Place a layer of potassium permanganate on top of powder mix.
  6. Quickly add several drops of glycerin on top of the permanganate.
  7. It will only take a moment for this reaction to ignite the thermite so be sure to de-ass the area with the quickness. If you can't stop yourself from watching, wear eclipse viewing glasses or welding goggles. Seriously, it's bright.
  8. Avoid breathing in the resulting smoke. It's probably toxic 15 ways from Sunday.
  9. Wait for everything to cool before retrieving drive.
  10. Return the drive to the customer as evidence of secure wipe.

  • Fresh crude from a Texas Oil Derrick
  • Coal you mined out yourself
  • Used Pine tar
  • Powdered Boxing gloves
