Exact same problem on 2011 MBA.
- Noticed message after Time Machine backup failed.
- Ran verify with the following results
- restarted with command+R then ran verify and repair in recovery mode with success (all fine)
- ran verify again, fails, again.
Modal message:
This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.
