    I use DiskWarrior version 4.4 to repair permissions in 10.7.3 and it works quite well for me. Alsoft is a company that has kept up well for Mac users in the past.

    It's now April 12th, 2012 and you STILL can't Repair Permissions or Verify Disk on a RAID Boot volume with 10.7.3.

    I have the same problem.  I wish this DiskUtility bug would be fixed soon, as having the ability to check my RAID would help me diagnosing another issue I'm having.

    Disk Utility has not found ANY permissions to repair for many months now through multiple updates. Mac OS X Lion 10.7.4 (11E53). I tried running permissions repair through terminal and it ran just fine and found nothing to repair.


    By the way, I have no RAID drives... just 4 internal and 2 external. I have sent a bug report also.


    My machine has started crashing on start up or starting up slowly.... which may or may not be related.


    Just adding my 2 cents.

    I know this is old Michael, and who knows if you are still around, but your post gave me a good laugh   I'm not making fun or anything, but the way it's written makes it sound like you couldn't repair permissions on your wives.  I absolutely know how that feels!!!  Anyway, again, not making fun, just thanking the list for a hearty chuckle.

    If the diskutility GUI does not repair permissions how can the command line do any better?  Diskutil used the same repair packages.


    So with 10.6.8 and RAID volume it does not seem possible to repair disk permissions. I have tried the GUI, command line and Cocktail - they all of course do the same thing, which does not work.  What does work is if you go in and change permissions manually with chmod.

    I have 1Tb external hard drive. And I am not professional. I had same problem exactly like yours. I tried to repair my HD but couldn't repair. Finally I found Miro was using my hard drive. I quit miro and tried again. It solved my problem. error message was something like- live volume or I don' t remember.

    l0l0's post is helping me do my repairs on an external softRAID tower via Terminal.


    "Repair Disk" didn't work in Disk Utility but I'm able to run things in Terminal.


    I used this step:


    diskutil list


    then I did:


    sudo diskutil repairDisk diskx (mine was at disk8)


    then I did:


    sudo diskutil repairVolume diskx (mine was at disk8)


    These worked for me.


    I tried Disk Utility again hoping I had jumpstarted it but it still doesn't work.

    I wonder if Disk Utility is somehow not running with sufficient permissions...(the sudo makes you the boss of Terminal).


    I'm going to explore some more.


    Anyone trying to repairPermissions on an external or internal drive that doesn't have a bootable OS on it, it will be greyed out.

    Reparing Permissions is only for boot drives.

    I was wrong....


    repairDisk in Terminal gives the error:

    "You cannot specify an AppleRAID set and it should not have a partition map"




    Well at least repairVolume seems to work.
