We got a tip about a USB CD destroyer. We found its methods amusing as it just scratches the CD as seen above on the left. If you really have data security issues, perhaps something more than scratched plastic should be used. There are a lot of paper shredders that can also shred CDs, what about taking that shredder with the burnt out motor and turning it into a hand-cranked shredder that doubles as a CD killer?

Got a lot of optical media that needs to go? These folks developed the chain-gun of CD shredding with an automatic feed. This consists of a CD shredder and a slew of discs connected with packing tape. As seen in the video after the break, the shredder advances and the next disk is pulled into its jaws.

Microwave has been a popular bringer of death for disc media. The light show and resulting chaotic art (above on the right and after the break) are what make this interesting, but it’s pretty hard on the much-loved kitchen appliance. What we’re really looking for is a way to force a CD/DVD writer to overwrite data. The fact that burnt discs, rather than factory pressed versions, are what normally need to be disposed of makes this a hack waiting to happen. Why isn’t this a standard hardware feature of all drives, and can it be implemented in software?

There’s always the low-tech snap, scratch, or mangle methods. We usually just scratch the foil off the top of the disc.
