Hello, I bought a LaCie 250GB drive a few months ago and it worked fine on my iMac 800. It works fine on my iBook too. It will not work on my new iMac 2.1ghz machine. I've tried two different cables and all ports but the drive simply will NOT show up. Sometimes if I just switch off the drive MacOSX comes up with the "Device removal" error but even that's stopped now. Switching the cable over to the iBook and the drive appears immediatley...weird? What gives? Cheers!
