Trying to repair my disk results in the following:
Verifying volume “Drobo” Checking file system Checking Journaled HFS Plus volume. Checking extents overflow file. Checking catalog file. Invalid sibling link The volume Drobo was found corrupt and needs to be repaired. Error: This disk needs to be repaired. Click Repair Disk. Verify and Repair volume “Drobo” Checking file system Checking Journaled HFS Plus volume. Checking extents overflow file. Checking catalog file. Invalid sibling link Rebuilding catalog B-tree. The volume Drobo could not be repaired. Volume repair complete. Updating boot support partitions for the volume as required. Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
As you may have guessed, this disk is on a Drobo unit. The Drobo utilities indicate that everything is okay with the physical drives.
The problem is this disk has Time Machine backup data on it. I was thinking of using SuperDuper! to make a disk image of it but I'm not sure how that will turn out since there is Time Machine data involved and rather than risking it I figured I would ask first.
I can mount the disk but it mounts as read-only.
How can I (preferably) backup (or move) my Time Machine data on this non-repariable volume to another one so I can format the non-repairable volume and use it again? Will SuperDuper! work for this?
