[MacDV] Re: OT: Best way to destroy used CD-R's

[Matthew Guemple]

If you just grab a chunk of Gaffers (duct) tape or even good masking 
tape (not white tape) you can easily peel off big chunks of the 
reflective surface... you only need to peel off a little of it and the 
disk is useless.

But just snapping them in half is probably the easiest way. Unless 
you're a sleeper for the SAS or something... in which case shears or a 
shredder is your best bet.
