I was experiencing some constant browser and programs so I restarted my MBP and ran Verify Disk. Here is the error message: Verifying volume Macintosh HD Checking HFS Plus volume. Checking Extents Overflow file. Checking Catalog file. Incorrect size for file keyedobjects.nib (It should be 0 instead of 6383) Checking multi-linked files. Checking Catalog hierarchy. Checking Extended Attributes file. Checking volume bitmap. Checking volume information. The volume Macintosh HD needs to be repaired. Error: The underlying task reported failure on exit 1 HFS volume checked Volume needs repair It would not even allow me to Repair Disk. Anyone know what I should do?
