Hi, I have G4-450 DP running 10.2.6. I ran Disk Utility and Disk Warrior and received these errors on 1 partition on 2 separate drives. One of the partitions is a boot volume. After "checking catalog file" the message "keys out of order" (in red) followed by, "Error: The underlying task reported failure on exit. (-9972)" this was on the boot volume on drive 1. I received "Invalid number of allocation blocks", "Error: The underlying task reported failure on exit. (-9972)" On a partition on my second drive. I can't access either of these volumes. What do I need to do from here? Thanks, Gregg (also posted on g4 list, no response yet.)
