Weird disk drive

I've got the weirdest disk drive ever. It's a standard 5.25" mounted inside a factory made metal enclosure. It has a fixed power cord coming out the back with a power switch. Inside is a simple power supply (transformer and a couple regulators and capacitors) that puts out +5V and +12V. There's a power connector going into the disk drive power socket. Here's the weird part: there is no data cable. There is no port or connector or anything on the enclosure for a data cable. There's not even a cut-out for a data cable. It's basically just a disk drive that powers up and spins if you put a disk in it. I initially thoughtt that it must be a degausser or something, but there's nothing inside that would indicate any such operation. OK, I admit it. I'm stumped. No markings on the enclosure anywhere. Any ideas? Responses copied to me directly would be appreciated. Otherwise, I'll follow any follw-up thread in the archives.
