I'll try again... Does anyone have any ideas? Tiger on a G4, with a second drive, rebooted last week with a dialog saying "you need to restart..", with a power button graphic behind the dialog. Tried to restart several times with no luck. I then booted into safe mode. When I restarted with the option key the slave drive was no longer available. It is still present as a device on "About This Mac", but there's no mount point. There were some errors on it when I ran disc utility, but they were not repairable. How do I access the second and/or remount it to repair it? Help please?
