    I have 2 laCie hard drives, They have been working fine for over a week i have one backing up with time machine and the other just as a spare drive.

    Shut my mac down last night by ejecting the disc’s then shutting down the mac.

    Turns the mac on this morning and they are not mounting, I have the connected via firewire 800. I’ve repaired permissions & also repaired the disc’s.

    They do connect thou via 400 port on the front of the G5. So if my firewire 800 port is broke is there a way i can try and find out?

    I had the same problem. Try resetting the SMU. Shutdown, unplug all the cables, give it 30 seconds or so, hook eveything back up and reboot.

    good luck
