A device for discouraging unauthorized use of a computer disk drive, cassette tape deck, CD player or similar equipment. The device includes a block, a flat, projecting member which is sized to fit inside the slot opening of the disk drive or tape deck, and a "showcase" type locking mechanism. This type of mechanism employs a relatively thin strip of metal, having a serrated edge and a cylinder lock which ratchets along the strip, making for a compact lock. In this application, the serrated metal strip is bent 90 degrees at one end, forming a hook that holds on to the inside wall of the disk drive or cassette chamber. When the device projecting member and locking strip are inserted inside the slot opening of the drive, filling it, the block is pushed and held against the face of the drive, blocking access to it.
