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.


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.

Yes, I believe that's pretty much what they do with hard drive platters
that contain classified data - Grind the mag layer off then shred the
substrate.

Now that you have revealed where they are, you need to go retrieve
them and put them elsewhere. Loose lips...

A memery stone? Is that some kind of newfangled hybrid word?

Some government agencies require "old/dead hard drives" be sent to

Me! I think of Thermite...

Nah- they degauss the whole thing with an electromagnet that would make
a scrap yard jealous, and then throw the whole damn thing in a chipper
mill. No, I'm not joking. Yes, I do work for them.

No marker or shredder required, just put thumb on one edge, fingers
on the other and squeeze. It will bend like a taco, and then "explode"
into a hundred shards., and split into 2 separate layers with the
"aluminum foil" layer flying in the wind.

I expect it varies with the classification level of the data. The grind
and shred routine is / was indeed used on some HDD media that contained
classified data.

Yes, by piecing together the chips of DVD the guys left
behind. Like popcorn, in Hansel and Gretel.

Just remember to do the label side. *That's where the data lives.-


that is true for a CD, but for DVDs the data lives inside between the

Give them about ten seconds in a microwave oven. Maybe not even

Can anyone here recommend a quick,
cheap, easy way to do that? I've heard
that drilling 2 or 3 1/4" holes in them
does the trick, but that is just a rumor
to me. What about placing them, one at
a time, in a vice, half clamped tight
and the other half then struck hard with
a hammer - hoping to break it in half?

Suggestions and experience reports
appreciated.


A disc shredder does the job quick. If you choose to shatter them
with a hammer wear eye protection. A propane torch will melt them,
but may produce toxic fumes if you allow them to burn.

You buy and detonate a 1 kiloton nuke bomb, with the discs under the
bomb.

then while your cleaning up the nuke waste contamination, pick up
whats left of the discs, encase in concrete and send to a nuke waste
repository, like cheyenne mountain.

somewhere in the next million years the mountain will be breached, the
nuke waste released will kill everyone in the area, then the
yellowstone old faithful volcanoe will erupt blowing whats left of
your discs on a trip to mars......

archeaologists there will unerath them in 2 million years..........

by then no one will have a cd reader.so your data may be secure

Not at all within government specs. You have failed CIA procedures.
