@Chakris - You should do a search on the FireWire thing. Were you connecting them in target mode? Apple moved everything to the Thunderbolt connectors. Wouldn't surprise me if they disabled support for FireWire. It's not like we all spent $$$ on cables and connectors or anything. Ugh.
I kinda think I ran an OS update once that did funky things to the name of the HD. That can usually be changed in the Disk Utility. Be careful that it doesnt reformat or erase anything when you do it. I've changed the HD name before, and I'm thinking it was pretty easy. I do know they don't have the drive icon on the desktop by default, but there is a way to put it there. Search on that too. It was easy steps.
