I am looking for a portable, bus powered, hard drive to use with my powerbook G4 (17", 1.5Ghz). I know that most won't work, as the USB2 bus won't power most drives. Does anyone have any expereince on a drive (USB or FireWire) that will work? If I get a PC card adaptor with USB ports will that work? Any suggestion on Brands? I actually bought a WD 120 GB Passport drive, so i know that doesn't work as it stands. Any suggestions woudl be aprreciated.
