I have just purchased a My Book Studio Edition II drive to use with my IMAC. When I plugged the drive in using the Firewire 800 cable the drive would not mount and was not recognized by my computer.
I tried swopping the cables for the one I use with my portable hard drive, and it still would not work.
I then tried using the USB 2 cable, and immediately the drive mounted.
I then tried updating the firmware for the hard drive but the Firewire 800 connection still does not work.
Has anyone got any ideas why USB2 works and Firewire 800 does not or have I just got a faulty unit?
PS. I am running Snow Leopard at the moment as I have not upgraded to Lion yet.
