Disk Utility can't Verify Disk Permissions" and "Repair Disk Permissions"

I tried to run "Verify Disk Permissions" and "Repair Disk Permissions" on an external partition, but they all grayed out! "Verify Disk" and "Repair Disk" were fine! The "Owners Enabled" is "Yes". Why they were grayed out ?!
Get Info on this volume showed:
Ownership & Permissions:
You can "Read & Write"
Details:
Owner: admin
Access: "Read & Write"
Ignore ownership on this volume: checked or unchecked STILL grayed out!
Other partitions on the SAME drive are able to do "Very Disk Permissions" and
"Repair Disk Permissions" (as they are NOT grayed out !) The ONLY difference
between the one (CAN'T) and the rest partitions is that one (CAN'T) has
owner by "admin", and the rest partitions (OK to veryify pewrmissions) are owner
by "system". ANY CLUE ?
-DC

The options to verify or repair permissions are only available on a disk with Mac OS X 10.2 or newer installed, and all Mac OS X versions set the owner of the partition containing them to system when installed.

Disk Utility can't "Verify Disk Permission" and "Repair Disk Permission"

I booted up the Leopard 10.5.5 server from the Install Disc, and tried to do disk checks on all drives using Disk Utility.
When the system drive was selected all the "Verify Disk", "Repair Disk", "Verify Disk Permission" and "Repair Disk Permission" functions are able to perform, however, if the non-system drives are selected only "Verify Disk" and "Repair Disk" are able to perform, the "Verify Disk Permission" and "Repair Disk Permission" are GRAYED OUT ! and UNABLE TO perform the permission check and repair!! Any idea ?

Hi, I'm having a problem could be related. I've a 3 years old Xserve (not intel) with 3 HD managed by the apple original RAID board, all that running Mac OS X 10.4.
I remotely manage the server from my mac running OS 10.5.6 and Server Admin 10.5.3.
Well, I simply cannot propagate permissions because when I do it, Server Admin freezes and i must force it to quit. Obviously, privileges are not propagated.
All that di NOT happen 1 month ago when i was "happily" running Mac OS X 10.3.x and Server Admin 10.3.x. Upgrading has been a big boomerang.
Any idea? Thanks

Lion "Verify Disk Permissions" and "Repair Disk Permissions" grayed out

Please help!

Repair using Disk Utility was OK on the volumes, but Repair for the drive was grayed out.
That's very odd. Is your drive G.U.I.D?
Boot into Safe Mode (Hold Shift-Key), then boot normally.

Disk Utility hangs ("not responding") when attempting to Repair Disk on Time Capsule sparsebundle. Help.

I am trying to improve the performance of my Time Machine backup and retrievals via my 2nd Gen. Time Capsule from my iMac Core 2 Duo hard drive with SL 10.6.8. The incremental backups generally take 20 - 40 minutes each hour generally with fewer than 100 MB of data being backed up. I have read through numerous threads on these forums about Time Capsule and Time Machine issues as well as the very helpful Pondini site (http://web.me.com/pondini/Time_Machine/Home.html) and have tried many other suggestions (listed below), but have been unable to attempt a Disk Utility repair disk on the Time Capsule sparsebundle file.
After locating the sparsebundle 'file' in the finder under Shared/TC/Data, I am only sometimes able to drag the sparsebundle into the Disk Utility volumes and disk window. About fifty percent of the time, Disk Utility hangs when attempting to drag in the sparsebundle. If I am able to get it listed and click on "repair disk", then the beach ball begins to spin and nothing happens. This occurs whether or not I first use AirPort Utility to "Disconnect All Users" from the Time Capsule. I have given it over one hour to attempt the repair disk, but nothing happens, i.e., not a single message shows up in the detail window. The beach ball just spins, and Disk Utility shows up in red as "not responding" under the Force Quit menu.
Also note that on my new Macbook Air, Time Machine runs quite quickly via this same Time Capsule from my new Macbook Air using OS X Lion (which seems to indicate that the Time Capsule drive itself is OK).
I would appreciate any tips on getting Disk Utility to run "repair disk" on my sparsebundle, as I seem to have exhausted most other options (see below) for improving Time Capsule performance -- aside of course, from wiping the Time Capsule clean and starting all over.... (which I really don't want to do, and from what I've read, has not helped some people who've tried this anyway).
Many thanks!
Although I would like to focus this thread on the Disk Utility / sparsebundle "Repair Disk" problem, I should mention that I have tried the following other things:
1. Repaired disk permissions on my hard drive
2. Used Disk Utility to run "repair disk" on my hard drive after starting up from a SuperDuper external backup
3. Run DiskWarrior on my hard drive, again, from a separate startup disk
4. Did the "full reset of Time Machine", a la Pondini Troubleshooting #A4
5. Changed my computer and Time Capsule names to simple short names with only alphanumeric characters and no spaces
6. Ensured that my Time Capsule is being accessed only via ethernet
7. Relaunched the finder
8. And finally, attempting to use Disk Utility to repair the sparsebundle - thus the nature of this post

OK, no takers out there, but I answered my own question (sort of).
The answer is that even though Disk Utility shows up as "not responding" under the Force Quit menu and appears to hang, it is actually still working. A bit of patience shows that after about an hour, my Disk Utility was able to show the 1.44 TB Time Machine sparsebundle from Time Capsule in the disk window on the left hand side. Once this appeared, I was able to click on "Repair Disk" (note that prior to doing this, I had to "Disconnect All Users" from my Time Capsule using the Airport Utility program; otherwise you will get a "could not unmount disk" error). Again, the Repair Disk function appeared to hang Disk Utility as it showed up as "not responding" under the Force Quit menu. However, after about 8 hours, Disk Utility did run the entire Repair Disk protocol on the sparsebundle. The results DO NOT show up in the Disk Utility details window - so even if you are patient enough to let it complete, you will not see anything and may think that nothing happened. However, you can find the familiar results of the Repair Disk function by looking on Console - find the "DiskUtility.log" under Files: ˜/Library/Logs.
Unfortunately, I was hoping to find a problem that would have been subsequently repaired which would result in dramatically increased Time Capsule speed, but this was not the case. Disk Utility showed everything to be "OK" and I am stuck with a very slow Time Capsule....
(And of note, my new Macbook Air (OS Lion) Time Machine functions blazingly fast on both backup and retrieval to and from the very same Time Capsule - even though, these are occuring wirelessly via AirPort -- granted the size of this sparsebundle is an order of magnitude smaller at this point, i.e., only 10 GB right now)
Would still be happy to hear of any similar experiences or tips on getting Time Capsule to work more quickly.

Disk utility. can't verify permissions

Now using Maverick OS 10.9.5 on my iMac duo core 11.
My computer has been very slow to action 'clicked commands' so I tried to Verify Permissions .
It came up with a problem with Application/ Safari V 7.1.2 but would not complete verification.
I stopped it and repaired Permissions and it repaired the Safari problem. But still slow.
I tried resetting Safari and it seemed to work for a while but then slowed down again.
Can you help?

Try a restart.
Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.
Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Isolating an issue by using another user account
Try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear and again when you log in. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don’t do them all at once.

Disk utility can't verify/repair partition map.

When trying to verify/repair my hdd it gives me the error: "Error: Couldn’t find the target disk for this operation."

You should already have a Recovery HD that was created when you installed Lion or came with the computer pre-installed. The Recovery Disk Assistant simply makes a Recovery HD you can use if one is missing from the hard drive.
However, repartitioning will destroy all the data on the drive so you will have to reinstall Lion. It will also remove the Recovery HD from the drive, so you will need to use your flash drive Recovery HD to boot the computer and get to the recovery main menu. The essential process:
Install or Reinstall Lion from Scratch
If possible backup your files to an external drive or second internal drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
You will need to use the OPTION boot method to select your recovery flash drive as the boot volume.
Repartition the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
Select one partition from the Partition Scheme dropdown menu. Click on the Options button and set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
When the destination drive is displayed click on the Display Other Drives button and select your internal hard drive as the target.

Disk Utility can't verify MBPR Macintosh HD?

I have a 13" Macbook Pro with Retina Display, 2.9 GHz Intel Core i7, 8GB 1600 MHz DDR3, 500 GB storage (of which about 250 GB is free).
When I launch Disk Utility, select "Macintosh HD" in the left column and click "Verify Disk," the process begins ... but abruptly ends after a few steps, without ever fully completing.
Additional info: When the "Verify Disk" process begins, if I place my ear near the keyboard, I can hear a some very quiet, squeal-like noises from inside the computer at various points during the verification process. The noise stops as soon as the verification process craps out.
Has anyone experienced anything like this?

FYI
Turns out this is a known issue in Mavericks:
https://discussions.apple.com/message/23642923#23642923
https://discussions.apple.com/message/23536043#23536043
Just checked my wife's equally new MacBook Air and it's doing the same thing ... so I'm going to continue to assume it's not a hardware issue.

Disk Utility can't verify or repair hard drive

I started up my Tibook using the install disk and ran disk utility to try and repair my hard drive and it went through the verification process and then said that there was an error and it could not repair the disk. It says that it needs repaired, any suggestions?
Also, when I come back to my computer after being gone several hours, I'm having trouble getting the computer to respond. It's not supposed to go to sleep or go to screen saver, but when I come back, the programs take a long time to respond - any ideas on how to fix this?
thanks in advance.

I keep getting input/output error put when trying to make a complet copy of my hard drive, which also has vista using fusion.i have did the permissions and repaired, disk verify.

error input/output

Yes. Formatted correctly. It' s new ext HD and I made a the first back up on it a few days ago using time machine while my computer was in safe mode. When I was able to restart my computer normally I quickly set up a time machine backup to my larger 5 TB ext drive. Also new and formatted for my mac. I was in a rush to get it going before I left for work so maybe I did something wrong. IDK. I can't remember but it did ask me about switching drives vs setting up. Although I don't see why the computer wouldn't see the drive.
I did try another firewire cable and no change. Checked connections again. The HD turns on and the blue light comes on (it's a La Cie d2 quadra deskdrive)
Is the SMC reset where you detach devices and restart? My printer, keyboard and mouse are all wireless and right now I don't have anything else connected.
I'll try another PRAM reset too.
* Question:
When I connect the 3 TB drive it starts up but I don't see it on my desktop, finder sidebar or in disk utility. If a hard drive starts up but doesn't show up on your computer how do you safely shut it down before disconnecting? I've been clicking on the desktop and then pressing the eject button on my keyboard just in case.

After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely

After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely." What do I do now? This is an iMac and I'm running 10.6.8.

Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it. See below for how to clone a drive.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
Clone using Restore Option of Disk Utility
1. Open Disk Utility.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
       it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
      the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode.

"Disk Utility can't repair this disk...and restore the backed up files"

Hello, my macbook crashed a few days a go as well and after going to the recovery drive and OX Utilities tried to verify and repair disk it gives me this error "Disk Utility can't repair this disk...and restore the backed up files" is the second time that occurs after replacing the hard drive for a new SSD, i thought my problem was solved and is not. Any Ideas? the only other thing i can think of is the logic board?

Backup your files and arrange for an appointment at an Apple store genius bar for a free evaluation.
Ciao.

Disk Utility can't repair permissions

For the first time I neglected to repair permissions before security upgrade and now I find I can no longer repair permissions. Everything goes as normal until about 75% done and then it just freezes. I have tried running it from the install CD but it does the same. I used the disk repair and got this error message;
ERROR: The underlying task reported failure on exit (~9972)
1 Volume could not be repaired.
Computer otherwise OK. AHT reported all OK.
Is this the start of an HD failure or some querky software malfunction? Help needed!

If my HD has developed a bad sector then surely a clone will not work?
My best guess is that the cloning would fail when it tried to access the data that's referenced in the bad directory node. I've had similar problems when trying to copy files when there were directory problems. You may not have a bad sector per se, but certainly the directory record is damaged in such a way that Disk Utility can't reconstruct the record.
If I moved all my APPS folder to another HD and then did a Zero and format on this one could I then still use the APPS folder with a new install by repairing permissions?
You have to remember that apps store files in other locations - particularly in the /Library, /System/Library/ and /Users/username/Library directories. While you can copy the Applications directory to another drive, you're liable to miss supporting files the apps are going to look for. Since there's no real way to determine what the damaged directory is referencing, you'd be chancing something's going to get missed and leave you with apps that won't run. The only way I've ever been able to find what directory erorrs were pointing to was to copy files to another drive one chunk at a time until I found the offending directory and then narrow down the search by copying files individually. Given the nature of OS X to store files in directories that are otherwise hidden from the user, this can be a complicated and tedious process.
Since Disk Utility running from the install disk can't repair the damaged directoy record, I'd go to the Disk Warrior repair strategy next.

Disk Utility can't repair and refuse Partition to work

Hi,
Is there any ways to solve this message appearing in the Disk Utility?
When i click repair disk on Disk Utility, message shown;

Then i thought its might not be repair just by one repair.
After that i try repair again however this message still appear.
I ever try restarting and shutting down my MacBook but the message still appear.
I do some research and find that one of the message in the list can be safety ignore
http://support.apple.com/kb/ts1448
Hence i just ignore the message.
Meanwhile i try to partition my hard disk and message shown;
Partition failed
Partition failed with the error:
Could not modify partition map because filesystem verification failed
I getting too frustrated about this problem.... ARRRGGGGHHHH!!!!
Any solutions are welcome. Thanks

You can find an extensive discussion of the permissions repair messages you can ignore at Topic: Permissions Snow Leopard 10.6.4. Nothing on your list of permissions messages is unusual or indicates an issue that needs correction.
However, the partition failed message indicates that you need to run Disk Utility's Repair Disk function on the disk volume. Note that if this is your normal startup volume, you will have to start up from some other disk, such as your installer disc, & run the Repair Disk step from it.
If Disk Utility is unable to repair the HD, you can try more powerful (& costly) utilities like Disk Warrior, but there are no guarantees that any of them will be able to fix all possible problems the HD may have.

Error disk utility can't repair this disk...disk and restore your backed-up files

I have been working on a project using an external hard disk. I used my Macbook Pro (2010) to create this project and files (about 31 GB). Now I am trying to open the disk on my iMac (2014) and it doesn't show up. I can see the HDD when I use disk utility but get this message when I try to repair/restore the disc:
"error disk utility can't repair this disk...disk and restore your backed-up files"
The funny thing is that the disk works absolutely fine with my Macbook Pro. What am I missing?
