I have a Seagate FreeAgent Go 120 GB USB External Hard Drive ST901203FGA1E1-RK. I took the drive out to use for a laptop drive that died. I would like to get a drive only and put back into the SeaGate case. I want to know if I get a larger drive to put back in the case of the SeaGate, will the controller electronics support the larger drive? 500GB? 1TB?
