1 HFS volume checked, Volume needs repair.

I have run Disk Utility in the attempt to find out why FCP5 stopped recognizing my Canon ZR400 which I used to use for capturing. After I updated the system with the new QuickTime 7, I started to have all sort of problems which I managed to fix, but this one. FCP5 just crashes when I try using this camera... but it does recognize my DVX100A camera and runs with it without any problem. Why is this happening? Any help please.

This is the message I get every time I run the Disk Utility, Verify Disk.

.. once its pot the problem, a pop up window appears and reads:

"First Aid failed
Disk Utility stopped verifying "Macintosh HD" because the following error was encountered: The underlying task reported failure on exit."

Is there any relation from this error to FCP5 not recognizing the Canon ZR400 which used to recognized?

Any help will be highly appreciated.
