I am unable to mount from my SuperDuper copy but only under some circumstances:

(a) start-up works fine if I select my SuperDuper copy as a start-up volume under system preferences.
(b) start-up does not work if I shut down the computer and then restart with the option key pressed. I only see the original hard drive as a start up volume. Same, if I start up with option-command-shift-delete. I only get the little folder with the question mark...
(c) interestingly, it does work if I select restart... (instead of shut down...). Then the copy is recognized and is mounted correctly.

This behavior is new with Leopard (10.5.2) and/or SuperDuper 2.5. The very same firewire drive (LaCie 500GB) worked fine under 10.4 and SuperDuper 2. (FYI my computer is a PowerBook G4).

Any suggestions???
