Apple-branded Toshiba Hard Drive. I pulled this from my Powerbook G4 the day I got it and placed it in an external case. Used it for making backups about a dozen times.
It's a Toshiba MK1016GAP. 10 GB, 2.5"
I need to pop it back into the case to erase the contents, so if you want it loaded with interesting (to me!) stuff, let me know and I'll have a little fun.
