HP6000-660S disk system I bought at Weird Stuff in Sunnyvalle, CA. I hooked it up to my laptop with a PCMCIA SCSI controller card and it saw three HP 2212A disks. I had to open it up to see what was inside - while it's very heavy I didn't expect these beasts. If there is any data on them, Windows wouldn't know what to do with it.
Each disk is covered with a heavy metal shield that is screwed onto the drive both on top and on the front face. I'm not sure how it is removed, so I can't find the real drive manufacturer or model number. The shield is labeled with model number 97548-60061, which appears to be an HP part number for a 660mb disk. 1.8gb of SCSI disk from ~1990!
