    Hey guys, hope all is well. Long-time reader, first-time poster.

    Ran into a problem with an abrupt shutdown twice while I was re-starting my suddenly slow Macbook Pro (OS X Yosemite, 10.10). I ran Disk Utility, and I got this error message:

    "Invalid directory item count
    (It should be 5510 instead of 5511)
    The volume Macintosh HD was found corrupt and needs to be repaired/
    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 booted into Recovery HD, and ran Disk Utility there. Both the Macintosh HD & the OS came back clean with no errors (that's after verifying and repairing disk & permissions). Booting again normally, I still get the same error message above when I run Disk Utility, however, the "it should be _ instead of _" numbers sometimes change. Going back into Recovery HD again tells me I'm clean.

    I have not encountered the reboot issue (or any other issue for that matter) since the initial one -- essentially, it's saying the Macintosh HD is corrupt on a fully-functioning MBP. Just spitballing, but could it be the beginning of the hard drive failing or something?

    If anyone has any thoughts or advice, I'd greatly appreciate it.

    For anyone curious/having the same problem, I believe it's been fixed.

    Apparently, Disk Utility's report in Recovery does not always match what Disk Utility reads when the hard drive is mounted. I used "FSCK" from Single User Mode found here. Once there, the problem was identified and fixed, then re-run without issue.

    Thank you so much for posting this GWG8803. Following the guidelines you provided I was able to recover 125 GB of memory that had been unavailable ever since I uninstalled a virtual windows 7 machine using the Boot camp assistant back in early 2015. Thanks to your advice I just doubled the memory storage on my macbook air! Awesome.
