I recently swapped out the drive in my 320GB Western Digital Passport with the 120GB (Toshiba) drive in my PS3 (slim).
The 320GB drive works great in the PS3, but the 120GB drive isn't showing up in Windows 7.
The USB connected icon/sound properly trigger (and the device manager shows it as a USB mass storage device), and the drive lights up and I can feel it running, but I can't see it listed as a drive.
Any idea what's causing this and how I can get it running again? Could it be a power issue? Thanks.
