Can't restart from Safety Clone

[kbrigby]

New user here. I ran my first Safety Clone but received an error when trying to restart from the clone which is on an external Fantom 80GB Firewire drive. Here is the tail of the logfile:

I tried manually setting the Startup Disk and rebooting but it seems like my iMac (G4 800, 768MB RAM, 10.2.8) is still starting from the internal drive. I even tried restarting with the Option key held but I'm not sure if it worked.

How do you tell which drive is the Startup?

Why am I getting an error from Super Duper?
