Q: "Macintosh HD" available space issue

So I recently purchased this Mac (Retina MacBook 15", Late 2013) and everything was hunky-dory. However, recently, after playing some video games, I noticed that I was no longer able to save the game. The game in question (The Witcher) prompted me with a dialog box that says that there is no more space to save the game. I knew that I had over 300 GB free on my main partition, since I don't use a lot of it. But when I checked Disk Utility, this happened.

Here, it shows that there are only 18.9 MB left in free space. When I click on the actual partition, this is what I get:

Obviously, there is some disconnect between the actual partition and the hard drive itself. When I press "About This Mac," it also shows the correct amount of space:

Any help would be appreciated. I turned Time Machine on and off, rebooted, repaired Disk Permissions and the Disk, but nothing changed. Thanks!

MacBook Pro (Retina, 15-inch, Late 2013), OS X Yosemite (10.10.1)

    The screenshots are normal for a Core Storage logical volume group, which is what you have. Your second screenshot shows the correct value for available space on the startup volume.

    And yet when I run "fsck_hfs," I get that the volume appears to be corrupt and needs to be repaired. Disk Utility (both from OS X and from Recovery) don't do anything in that matter. Is there a way to repair this volume or do I just need to reinstall OS X?

    Start up in Recovery mode, launch Disk Utility, select the startup volume ("Macintosh HD," unless you gave it a different name), and run Repair Disk (not Repair Permissions.) If any problems are found, repeat. Then restart as usual.

    If you don't already have a current backup, you must back up your data before you take the above step. You may be able to back up, even if the system isn't fully functional. Ask if you need guidance.

    Directory corruption in a MacOS journaled volume is always the result of a drive malfunction. It's not caused by power failures, system crashes, or anything else. You might choose to tolerate such a malfunction once in the life of a drive. If it's repeated, the drive must be replaced, or there is some other hardware fault that needs to be corrected. Ignoring repeated directory errors will result in data loss.

    You should not run/use fsck via terminal on system which is currently in use. Possibly, that is the reason, why you are getting in result that Macintosh HD Volume is corrupted.

     

    If Disk Utility run through Recovery Mode does not show any errors, then your Macintosh HD Volume is ok. If you need to run fcsk, here you have information, how to use it: Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support

    I already tried everything mentioned. I ran Disk Utility through Recovery, and it said that the hard drive is okay. However, when I ran fsck through Recovery (and through Single-User Mode), it said that the hard drive is corrupted and needs to be repaired. I'm going to the Apple Store later today to see if maybe I'm missing something.

     

    And the system itself works just fine. There don't appear to be any issues with OS X. There is only that one corruption error.

    This HD is definitely corrupt. The name "Macintosh HD" should only be on the partition, not on the actual drive. The physical drive should be showing a name like "751.28 GB APPLE SSD SM768E Media". That is obvious corruption plus that pic of DU is missing tons of info about the drive that should be showing like this.

     

       Disk Description :    APPLE SSD SM768E Media                           Total Capacity :    751.28 GB (751,277,983,744 Bytes)

        Connection Bus :    SATA                                                              Write Status :    Read/Write

    Type and Location :    Solid State Disk, Internal                            S.M.A.R.T. Status :    Verified

                                                                                                Partition Map Scheme :    GUID Partition Table

     

    It should not be showing the info that would show for a partition.

    Yeah, that turned out to be the problem. Apparently, the drive was formatted as a logical volume instead of as a GUID Partition Table. That was the source of the problem. After reformatting it properly, everything is back to normal.
