I have a MacBook Pro Retina, Mid 2012 running OS X 10.9 having recently upgraded. Using Disk Utility to Verify Disk it reported the following Checking file system Performing live verification. Checking Journaled HFS Plus volume. Incorrect number of file hard links Checking catalog hierarchy. Checking extended attributes file. Error: 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. I followed the instructions and the Disk Utility on the Recovery HD reports that the disk is OK. Rebooting and checking again with Disk Utility in my Admin account reports the same original error. Is this a problem? How do I fix it?
