I have an external back-up for my Time Machine. I think the power went out while it was backing up, and now I can a message that the drive is "read only" or "unavailable." I've tried to fix it using Disk Repair, but I get this message:

Disk full error
The volume Time Machine Backups 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.
Is there anything else I can try before I reformat the disk and start over with my backups? Thanks!
If you have Disk Warrior, that would probably fix it. It's the go-to program of choice to repair errors like that. Of course, it's alot cheaper to just reformat the drive ... I'd probably write zero's to it to ensure it's fresh (also resets the bad sector table).
