We have a bunch of ancient optical disks (kinda like CD's encased in their own cartridge) that we need to get rid of. The problem is they may contain a bunch of client info, Social Security Numbers, addresses, etc. and with all the identity theft going on I don't want to just toss them in the dumpster.

Any ideas for companies that offer data destruction services or am I better off with a "Sledge-O-Matic" of my own?
