    Hi all!

    I have a 15" 2012 Macbook Pro (regular, not retina) with a slight issue.

    As part of my weekly Mac maintenance, I run a disk utility permissions and verification scan on my internal hard drive (750gb Seagate Momentus XT). After upgrading to Mavericks, I noticed that after I while my disk had errors. They were all incorrect block counts, for different files.

    Thinking it was a software issue as a result of the upgrade, I reinstalled from scratch. Though I still received those errors sometimes upon a disk scan, there were no other consequences. However recently, there has been a few beach balls here and there, so I ran another disk scan. Lo and behold, another incorrect block count. The SMART status is verified, and otherwise it runs well without any unusual noises.

    So, is it likely to be Mavericks or my hard drive?

    Keep a good backup, your hard drive could very well be on the way out.

    Your drive is dying. I would replace it now before it gives out completely.

    Hopefully you have a good backup.

    There are a lot of tools out there to diagnose HDD's, but one simple program out there is SMART Utility. It can be purchased, but you're really only going to need the trial to open it once. It goes much further than OS X's SMART status. It may show you some sectors going bad and the drive failing. I'd start there.

    I ran the SMART utility software. It reports no errors as far as I can see, but I have attached the screenshot of the results just in case I missed something.

    I also ran disk utility again today, and it gave an 'invalid free block count' error. :mad:

    Thanks for the help so far! :)

    Personally I wouldn't rely on smart to give you a heads up. More often than not it's to late.

    Is there a definite way to check if it is failing then? The drive wasn't cheap as it is pretty high end, and I don't want to replace it on a whim.

    If it has failed, Seagate will be getting contacted! The drive is only just over a year old.
