I just got a new MBP, and today I sat down to do my first video capturing with Final Cut Studio 2. I have a 500GB Western Digital MyBook Studio, which I'd like to use as a scratch disk, connected via Firewire 800, and I have a Canon GL2 connected via Firewire 400. The MBP recognizes the hard drive, and I don't see anything about the camera (I don't know if I should - Macs are new to me.) When I start up Final Cut, the hard drive disconnects from the computer, and I get a warning that I shouldn't have unplugged my hard drive. It seems that as long as the camera is plugged in, Final Cut boots the hard drive off the computer. Without the camera, the hard drive is fine. But obviously I need them both. Any ideas why this might be happening to me? Thanks.
