Help I did the 10.5.5 update from 10.5.4 on my imac G5 - worked fine - then put computer to sleep - didnt wake up - rebooted and it takes ages to start. Firewire drives are no longer mounting.

Any ideas where to go from here?

external drives mount fine on usb - how do i check if this is hardware or just 10.5.5?

The only way to say it's the software would be to boot another version of OS X from something like an external FW drive.

Of course if you can't boot from FW ... sounds to me like it's time to reset your iMac SMU (system management unit):
