My MacPro has been acting very funky the last few weeks (hard drive errors in Logic, will not connect to other computers at times, bluetooth errors with mouse, etc) and have been trying to diognose it. The one issue that continues to resurface is this error message in disk utility:


Invalid volume file count

Invalid volume directory count


2 weeks ago, I saw this for the first time, got scarred, restarted with 10.6 install disk, ran disk utility and repaired it sucessfully! Yea! Continued working with the computer and stil buggy, recheck for disk errors, same message! Same remedy, fixed, run for 2 more days and error is back again!


My Question: what is causing this? Is it a hardware or software error? The last thing I want to do is spend all day reinstalling everything form scratch only to et the error again a week from now. What is the best way to diagnose this error?


Thanks, all help is greatly appreciated!!!

Mac Pro, Mac OS X (10.6.7), Logic Pro 9, 24GB RAM, UAD Quad

    I have seen Disk Utility claim to successfully repair disks with those errors but in actual fact not real fix them.


    You could try DiskWarrior. It will totally rebuild the directory structure on your disk and will be able to repair those errors.


    If the error persist even after repair with DiskWarrior it has usually been my experience that the disk is about to fail.


    No matter what you do I would first back up any important data on that disk.

    That drive is about to fail. Replace it.

    Since the data from the disk is read into RAM, it is possible for the data from the disk to be corrupted in RAM and making it appears as if the disk is in error. This is an unusual circumstance hence the reason we are all pointing our fingers at the disk.  Since you are having the same error with a brand new disk that does pint the guilty finger toward RAM now. It they are are saying they think it is RAM, I would trust them seeing as how they probably have more powerful test software then anything we have.

    RAM does have limited life expectancy. It does go bad. It doesn't have to short or anything of the sort.

    ..snip: this makes sense but the only problem is this is a recent problem and the computer ran fine for a solid 4 months prior with no changes to any hardware. I guess something could have easily shorted out or something, but just seems odd ..snip:

    It's tempting (even to me) to bring out that "but it was fine yesterday" until I remember something my physics lecturer told me, to quote him

    Doesn't help you but ......

    If you have the same problem again that is starting to sound like the disk is dying.


    I suggest you back up your data and prepare to replace it.

    Hey StirFry_2112,


    Have you found any other plausible solutions to your problem?  I've been having the same Invalid Volume Errors for the past two years.  Been buying new harddrives, but after watching videos online - Vimeo, Comedy Central, etc. the problem always comes back.  Can't seem to find any solution online either.
