I have a late 2013 rmbp and i decided to verify the disk. when i did i get the following failure saying i need to repair the disk by booting into recovery mode and into disk utility. "Storage system check exit code is 0. Verifying file system. Using live mode. Checking catalog file. Checking catalog hierarchy. Checking extended attributes file. The volume Macintosh HD was found corrupt and needs to be repaired. File system check exit code is 8.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." after i boot into recovery and repair a using disk utility, when i log back in and run the verify to make sure everything is okay, i get the same failure again. Any ideas on whats wrong or where to go from here?
