Good day all!

I'm having an ongoing problem with incorrect block count errors after syncing my podcasts to my iPod Shuffle.  Specifically it seems to occur when I am removing podcasts that I have already listened to, after adding new podcasts Disk Verify never shows errors.  When I remove them, I delete them from the Podcasts area of iTunes which then removes them from the Shuffle, this is when the errors present themselves.  I repair the disk from a flash drive that has the Lion installer on it and the repair completes properly and the disk shows no errors until I remove podcasts again, and the errors only seem to occur with podcasts, never any other files. This has never been an issue until I upgraded to Lion.  In an attempt to correct the problem I have deleted all my podcasts and podcast subcriptions and then resubscribed.  I have also reintalled the Shuffle software but the problem continues to reoccur.  I preformed a surface scan of the drive with TechTool Pro which is reporting no bad block errors.  Perhaps I should try DiskWarrior.  At any rate, I am mystified.  If anyone can shed any light on this situation I would be grateful.

    I have a similar problem. The hard drive of my MBP shows "Invalid volume free block count" error every now and then (I would say every month or so), but I haven't found any cause yet. I was thinking more to a hardware problem, but I haven't started troubleshoting yet. I have Drive Genius installed and that's how I discover the errors.

  • Father McKenzie Level 1 Level 1 (0 points)

    This problem sadly continues to occur.  It seems to be an OS X problem rather than an iPod problem. 

    After listening to my podcasts, I remove them manually from my iPod.  Disk Utility reports no problems at this point.  I then delete the "listened to" podcasts from the Podcasts area of iTunes.  Oddly at this point the Trash icon does not register that it has items in it when I remove podcasts, and the Trash finder window is also empty, although I know podcasts are present.  If i create a new folder on my desktop, then drag that to the trash the Trash icon shows "crumpled paper" indicating items in the trash, and suddenly the deleted podcasts are visible in the Trash finder window.  I now empty the trash.  At this point I again run Verify Disk in Disk Utility and this is when the Incorrect Block Count error occurs. 


    In order to diagnose the problem I have completely erased the hard drive, zeroing it out and reinstalling Lion.  Using TechTool I have run a surface scan, this shows no bad blocks and the Disk Utility SMART status shows "Verified."


    Any ideas?

    Did you start up from the recovery partition and use Disk Utility to run a repair routine on the hard drive? If no then I'd recommend you start by doing it. To load the recovery partition, restart the system with Command-R held down until you see the Apple logo appear in the middle of the screen. After this the OS X tools should load.

  • Father McKenzie Level 1 Level 1 (0 points)

    Thanks, yes.  I repair the errors from the Recovery Partition every time I receive the error, which is ONLY when I empty the trash of deleted podcasts.  Nothing else I do seems to cause this error.  Very odd

  • JohnZootsuiter Level 1 Level 1 (0 points)

    Having the exact same issue for many months with no known solution. Deleting from trash iTunes files.. mostly movies and TV shows.  Would love a solution

  • Father McKenzie Level 1 Level 1 (0 points)

    Yes, the problem contines to persist even after the most recent iTunes update.
    It appears Apple is not interested in sloving this issue.

  • Dissi Level 1 Level 1 (0 points)

    Yeah same "problem" here, first I knew about it was when my MBP restarted itself after trying to shut it down. On that occasion it specifically stated a conflict about the validity of a particular podcast.  Periodically I use Onyx and that lets me know, like last night, when there's an issue.


    I write "problem" because another thread on here points to this article - that says it's actually nothing to worry about.  Still a bit annoying though...

  • JohnZootsuiter Level 1 Level 1 (0 points)

    Hi Guys.. Fixed the problem by running Disk Warrior.


    To rebuild the directory of the computer's main hard drive, you will

    need to start up the computer from another source.


    The downloaded software will not start up your computer since it does

    not include any System files. 


    You will need to employ one of the following workarounds to rebuild the

    directory of a computer's main hard drive:


    (1)  Alternate Startup Disk:  If you have another drive (such as an

    external FireWire drive or an iPod with FireWire or a USB 2.0 drive for

    Intel-based Macintosh computers) you could install Mac OS X (the version

    which is currently running on the computer, or newer) on that drive and

    then start from it.  Install DiskWarrior on that drive's "Utilities"

    folder, (which is inside the "Applications" folder) and run DiskWarrior

    from there.


    (2)  Target Disk Mode:  Connect two Macs with a FireWire cable where the

    one is the "host" and the other is a "target".  The host Mac should be

    running an OS X in which DiskWarrior 4 runs.  In this scenario, the

    target Mac is the Mac whose disk you are trying to rebuild.  Start by

    shutting down the target Mac.  Then turn it on while holding down the

    "T" key.  The target Mac's drive will appear as a usable drive on the

    host Mac.  Run DiskWarrior from the host Mac and rebuild the target

    Mac's disk.


    If you cannot utilize one of the above suggestions then you will need to

    wait for the DiskWarrior disc to arrive.



  • Father McKenzie Level 1 Level 1 (0 points)

    No, sadly this does not solve the problem.  I have previously run the latest version of DiskWarrior, and although the replacement of the directory succeeded, the very next time I emptied podcasts from the trash the incorrect block count error(s) returned.


    As I previousy stated, this has only become an issue since Lion was introduced, I have never encountered this error in any previous version of OS X.  I have made Apple aware of the problem numerous times via the feedback form as well.  Perhaps it will be corrected in Mountain Lion when it is released.

  • Father McKenzie Level 1 Level 1 (0 points)

    Well, I was hoping this issue was fixed in Mountain Lion, but no, it just happened again

  • NoobianGod Level 1 Level 1 (5 points)

    I have the same problem as you guys, though I'm not certain removing files from iTunes has anything to do with it on my part. I too discover these errors via Drive Genius.

  • Markino Level 1 Level 1 (0 points)

    Same **** here, I have to repair at least once in a week!

  • Topher Kessler Level 6 Level 6 (9,735 points)

    If this is happening, then either your drive's formatting is severely corrupted, or the drive itself may be failing. Either way, I'd back it up ASAP and then try formatting and restoring from your backup, or alternatively (and arguably the safer option) replacing the drive.

  • Markino Level 1 Level 1 (0 points)

    I changed my Macbook pro to a new Retina 1 month ago, different laptop, same problem, I think is not a formatting problem.
