Well there's your problem!
Except that in the server rack right next to next to the document server was the accounts server which had 36Gb, albeit fewer of them. The server room was a small room in the basement of the building, next to the Reprographics room. At the time 36Gb server drives were expensive and we didn't have anything bigger in that server room. Well, everything in that server room probably only uses 1 or 2 switches to communicate with the rest of the building. The documents and email servers had 36Gb drives, and the HR server had 18Gb drives. They stole all of the drives from the documents, email and HR server drives. On entering the room the problem was quickly apparent; someone had stolen the hot-swap hard drives from 3 servers.
