My intel iMac locked up, and I had to do a hard reset. iTunes was still playing music from the external firewire drive when I did the hard reset. Upon power up, the drive would not mount. It appears in System Profiler under Firewire as Journaled HFS+ drive with no mount point. Thinking it might be a corrupt partition table, I ran Test Disk, then pdisk with the intention of rebuilding the partition table. However, they seem to match. Disk Utility sees the disk, but when I Verify Disk, it gives an error of "The underlying task reported failure on exit." (See attached file.) The Repair Disk button is selectable, but I am afraid to do anything that will write to the drive without fully understanding what condition the drive is in.
I have searched for 3 days now to find a similar scenario, but have not found one. It seems like there is no hardware issue with the drive, and all the data appears to be intact. I really don't want to lose the data on this drive. Maybe I'm just so freaked about this that I'm not seeing the solution. What should I do?
