The external FireWire drive with OS 9.2.2 on it shows up as being available for a restart in the Startup Disk window of OS-X's System Preferences, but choosing it and restarting only results in the flashing question mark. When I restart holding the Option key, the FireWire drive does not show up as a choice at all. SO, I must conclude that external FireWire drives cannot be booted from, at least not with this G4-733 and with the drives plugged into one of its built-in FireWire 400 ports. Two of these external drives are FW-800 250-gigers and the one on the end of the chain is a FW-400 120 gig (all three are Mercury Elite drives from Other World Computing).

Which brings up the question: is it wise to mix FW 400 and FW 800 drives on the same chain like this, with the chain plugged into a FW 400 port? Well, correct me if I'm wrong, but I thought it was OK to do it, and so far I've had no problems (knocking on wood). OWC's listed system requirements for the FW 800 external drives is either a FW 800 OR a FW 400 port. I thought (correct me again if I'm wrong) that a FW 800 drive plugged into a FW-400 port just limited the drive to FW-400 speeds. So I bought the two FW 800 drives looking forward to the day when I'd get a G-5 and be able to use the extra speed that these FW 800 drives are capable of. Was I right or wrong? Should I have stuck with all FW 400 drives?

Are you trying to change the start up drive while in OS 9 or OS X?

Try one of these methods to boot from the FW drive:

1) restart holding the option key--this should give you a selection of start up drives to choose among

2) restart from an OS X install disk and use the preference pane, there, to choose the start up volume

On the other hand, since you're using an older G4 and FW 800 drives, I assume you've added a PCI FW card? Are you sure the drives attached to that card are supposed to be to serve as start up disks?

I used Carbon Copy Cloner to put a copy of my system folder (OS 9.2.2) on one of my external FireWire drives, but I can't boot from it (I go back and forth from OS-X and 9.2.2). The drive shows up in OS-X's startup drive control panel as a bootable drive with an OS on it, but when I choose it and restart, all I get is the blinking question mark. This is a G-4 733 with FireWire two built-in 400 ports, and I have a chain of three external FireWire drives (one FW 400 and two FW 800's) plugged into one of the ports. The drive that I cloned OS-9 onto is one of the 800's. Maybe I should try putting OS 9 on the FW 400 drive, to see if it will boot from that, or are all external FireWire drives of any type just not bootable from, period?
