The model number of a small, 2.5" Laptop HDD I found in a computer at school, while scavenging for drive mounting screws (to mount our two new WD Enterprise 18.3 GB Ultra160s in a blazing RAID 5 (no parity) setup! =])

It was screwed into some thin sheet metal, and further mounted to the drive chassis with metal screws. What it's purpose was, i'll never know.

Last I checked, my system couldn't use the thing, so whether it's functional, is a question still left unanswered.
