Can't boot from firewire disk

[Thierry DL]

1st & 2nd tries failed. 3rd and following tries worked !! Really don't know why 'cause I didn't change anything on my system since yesterday... Well, anyway boot works, but now, when shutting down, it always freezes at closing session : dock, menu bar, desktop icons disappear. Only the mouse cursor and the background picture stay... The cursor can be moved with the mouse and the only thing that allow me to shut down is pressing the power button on the G5 for 5 to 10 seconds...
I repaired the authorizations, and no error was found.

I'll give a try with Disk Warrior to see if something bets better with this...

Thanks for the "verbose start" trick 'cause I'm not quite an "expert" on Mac OS X as everything works always fine with my mac :-)
