Heck my shredder has slot just for disk media - even cross-cuts :-))

I'd bet *on* the NSA or other similarly equipped groups being able to
get data off of your CD/DVD confetti. Granted the data at the cut points
is unlikely to be recoverable, but given the data density of the media,
each piece of confetti would probably yield a sizable amount of data in
their hands. If you need true security, you need to totally destroy the
data layer, probably via chemical treatment of the confetti bits, or
incineration of the remains.

Agree. First they need the "confetti".

My crosscut shredder's output gets mixed into 2 bags, and some of it
gets thrown in with the kitchen garbage each week. You'd have to not
only be willing to paw through our raw chicken guts, but do so for
several weeks in a row to get most of a given document or disc. If
you're that interested, have at it, I say...

Sandblasting or grinding of the data side works well. Once the layer
with the pits is dust, ain't nothing gonna put it back together.
