I do not get this thread... You want to make the data non-recoverable?

Create a vice.
- B&D workbench, vice bolted to bench, plywood squares separated by a
gap & central bolt to slide CD down over and even another "template"
over the top to shield most of the CD from flying about.
Whack the CD.
- Wear goggles, club hammer, club hammer & brick bolster.

It is non recoverable to anyone without very specialist custom
tracking equipment.

So it is recoverable then, a waste of time and effort.

Colleague modified a press to shear a stack at a time with a simple
jig assembled out of flat bars.

Still recoverable

Do not burn them, the chemicals released are noxious.

But done right, the data is non recoverable.

Even with a well equipped workshop (or two) I wouldn't **** about
cutting or bashing them to bits, I'd stick them in the microwave for a
few seconds.
