Time Machine not backing up after repair of PB.
I tried to continue using Time Machine after repair of PB (hard drive and RAM) but Time Machine caused G-Drive to churn for hours until I cancelled. There's room on the G-Drive (500 GB) but it will not accept a backup. Also ran Mac Utilites which also hung and cancelled that. I am able to copy to and read from G-Drive. G-Drive defective?
iMac, Mac OS X (10.4.5)
