I have been having the same issue with 2 differnet 2010 MacBook Pro's at work. I can repair it with dis kutiltiy in recovery mode, but it always seems to come back after a week or so. I am currently running 10.8.2, I also have a Mini and 2 iMacs runing the same version of the OS that do not have this issue. I am wondering if I am going to have to reformat and install from scratch to fix this. I am concerned that it might be a sign of impending drive failure. I think my issue started about 2 months ago.

As my luck would have it, the issue hasn't returned in the weeks since I posted this (Boy, you guys are good! ). Whatever was jostling my volume bitmap seems to have worked itself out. The last couple of Disk Utility runs have reported nothing but a clean bill of health.
I'm still open to theories, though, as to why this was a recurring thing for a short while.MacBook Pro (15-inch Mid 2010), OS X Mountain Lion (10.8.2)

Launch Disk Utility and click the icon of the physical drive itself (not the indented volume name). Check S.M.A.R.T. status. Any messages?
When you launch Disk Utility to repair drive is it from Recovery HD or from some other startup drive?
In any case, when you Repair Disk, if you haven't done so before, repeat Repair Disk until no errors are reported. Sometimes one error can mask another.
If you have done the above, it may help to try a more powerful disk utility such as Disk Warrior, but you will need to boot from the utility's disk or from a different startup drive.
