That is because when the head flies over the hole it crashes. Usually
just opening one up and hitting the platter with a hammer does a dandy
job.
Unless you have NSA hacking your drive, any of the data security erase
programs will work. They write alternating 1s and 0s across the entire
surface several times alternating them. I think 7 is the guv'mint
standard for "gone".
The casual hacker is stopped simply by formatting the drive and then
overwriting it with small garbage files until it is full. A simple DOS
batch file will do that.

Bend them with your hand until they splinter into a thousand pieces, or
put them in a microwave for about 4 seconds each. Or do both.

As the OP I'd like to thank all you guys
for the suggestions, serious and
otherwise. I took a pair of snips from
my garage and cut all the DVDs in half.
One half of each of them was then
deposited into a smelly and moist
dumpster behind a seafood restaurant,
and the other half were placed in the
trash bin at a Walmart about 20 miles
away. Task completed. Thanks again.

They burn too have been told! I think there was an old CD/DVD in a bag
of paper/cardboard scrap used recently to light the wood stove.
