Disk Utility verify or repair permission runs but doesn't indicate anything

Recently I ran Disk Utility to repair permissions after a software upgrade and the utility ran and ran, but no permissions were repaired and the utility didn't stop running. After an hour, I stopped running repair permissions. Does this indicate something remiss about the utility? Or worse? What should I do about this?

You might want to boot from your OS installer disk and launch Disk Utility. Repair Disk from there.

Disk Utility/verify and repair grayed out, using startup disk

I'm frustrated. I'm trying to repair my hard drive. I restarted from the OS X Mac Mini install CD (holding down the letter C when I heard the chime), opened Disk Utility from the Utilities folder, selected my hard drive image, but the "verify disk" and "repair disk" options are grayed out. I'm at a loss as to how to proceed. Thanks for any help.

"...opened Disk Utility from the Utilities folder,..."
If that's what you did then you didn't boot from the disk. You booted from your hard drive and that's why Repair Disk was grayed out. Try again. Insert the disk into the Mac restart and hold down the 'c' key and keep it down until you see the Apple logo and the spinning cog. You'll know you've booted to the installer disk when you need to select your language to proceed with OS installation. Select your language and then from the menu Utilities select Disk Utility.

Disk Utility verify vs repair contradiction

Since installing Yosemite, I've had an issue with Disk Utility; when I run a verify on my internal drive, it tells me I need to repair the volume in recovery mode. I boot into recovery mode and repair. Then restart and run verify in regular mode. It tells me again that the volume needs to be repaired, etc, etc. You get the gist of the cycle.
So which one is right? Verify or repair.

Others have seen this. If it shows okay in the Recovery Volume and everything is working okay, just let it go. You could also get the drive tested if you are concerned. Do a backup, preferably 2, just in case.
If you live near an Apple Store, make a Genius Bar appointment to have the computer tested. Supposedly there is no charge for testing. Use 2nd link if not near an Apple Store or aren’t in the US. Hardware Repair - Keeping Confidential Data Safe

Disk Utility verify of ISO burn fails, but md5 sum matches

Frequently when I burn a large DVD iso to a DVD, via the "Burn" task in OS X Disk Utility, the process results in a failure at the end of the verify process. However, if I check the md5 sum of the DVD against the published md5 sum for the ISO, the checksum matches. From this I assume that the DVD must have written correctly. Why does DiskUtility report that the verify failed?
System: IMac 27-inch, Mid 2011
OS X 10.9.5 (13F34)
Disk Utility: Version 13 (517)
Example: Here's the md5 sum of the downloaded ISO, which matches the published me5 sum for the ISO on the Centos website, and of the written DVD.
     # get md5 of downloaded ISO:
$ md5 CentOS-6.5-x86_64-bin-DVD1.iso
MD5 (CentOS-6.5-x86_64-bin-DVD1.iso) = 83221db52687c7b857e65bfe60787838
     # Centos site reports: 83221db52687c7b857e65bfe60787838 CentOS-6.5-x86_64-bin-DVD1.iso
     # read DVD via dd and pipe to md5 to get md5 sum:
$ dd if=/dev/disk2 | md5
8726528+0 records in
8726528+0 records out
4467982336 bytes transferred in 63.966136 secs (69849183 bytes/sec)
83221db52687c7b857e65bfe60787838
DVD was written via DiskUtility:
     1. File | Open ->select ISO from downloads folder
     2. Select ISO in left panel of Disk Utility
     3. insert blank DVD
     4. click Burn icon (pops up Burn Disc in: SuperDrive. Ready to burn.)
     5. click Burn
Result:
     dialog with "writing track"... "verifying" "Unable to burn "Centos....iso." (Verifying the burned data failed.)

its not your drive the problem its the disk if you use singapore produce disk there is a way to find out what kind of disk is made by you could have a disk of poor quality made by Ricoh, singapore disk dual layer disk of of top quality.
apple needs to update the firmware KA19 to be compatible to the Ricoh disk.

Disk utility - Verify and repair disk permission does not work

On my dual i'm trying to make a verify and than a rpair disk permission but the bar stop after a while and will never finish (even if the estimaed time is less than one minute).
Ideas?

Same boat... here's my thread from early this week:
http://discussions.apple.com/thread.jspa?threadID=1403467
Haven't had time to test the suggestion yet though.

Code compiles, runs but doesn't display anything, not even Exceptions?

The title just about says it all, but I don't even get a window, why is this? If it's some exception then it's not displaying for me to diagnose. Some pointers in what might be wrong would be really appreciated here - I'm pretty new to Java 3D.

Its because your public void Test() should be public Test(). Its a constructor, not a method.

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 - Verify Disk Permissions / Repair

I run Disk Utility > Verify Disk Permissions with this rsult:
Verify permissions for “Macintosh HD”
Permissions differ on "usr/share/derby", should be drwxr-xr-x , they are lrwxr-xr-x .
The following repair was successful.
A few minutes later I run Verify Disk Permissions again with the SAME result:
Verify permissions for “Macintosh HD”
Permissions differ on "usr/share/derby", should be drwxr-xr-x , they are lrwxr-xr-x .
What does it mean and how can I stop this error?
Thanks!

There is nothing in that message that requires repairing. That is why it keeps showing up.
The permission database has to be updated every time the system is updated. If they miss a change that they have made in the system, it will get flagged as you see, but doesn't mean anything is wrong.
That KnowledgeBase article also must be updated to reflect the things they missed.
All that message is saying is that the directory derby is now replaced with a link to another directory (the l vs the d). However, mine doesn't have a link. Did you install anything that might have updated derby?
If you open Terminal and enter this code, can you post the line that has derby on it?ls -al /usr/share/
I'm repairing permissions now to see what pops up for me, but that will take a little while.
Edit: I looked into the Derby directory and Derby is a Relational Database Management System used by Apache. So, did you install something that modified Apache, PHP, mySQL or something like that? It might have altered the link.

Disk utility can't repair but can't access the HD to back-up files?

I'm relatively new to MACs and have a 2TB Seagate with a good portion of our family pics on it. I opened the Disk Utility and attempted to repair the HD but get the message:
"Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files."
Here's where I'm stumped...I can't actually access the disk to back it up. At one point I was able to open the disk and see the files so I went and bought another HD to back it all up....but now I can't access it. I've found a few threads discussing using recovery software but the data isn't that important. I was using the HD as my Time Machine BU so I'm more nervous about re-formatting it and trusting it with my data again. Should I bother even reformatting it or just toss the thing?

You might try a force mount...
Launch/Utilities/Terminal and enter this command at the prompt
diskutil list
Press return. If it sees the disk, note the number of the disk (far left column) you want to mount.
Then, enter this command
mount /dev/(number of disk)
Put in the number no parenthesis.
Press return.
If you're able to mount copy off the data you need. Even if you can mount it, wouldn't I trust the disk again.
Try Drive Genius in demo mode to run a surface scan and see if there are any bad blocks.

When I run disk utility, verify permissions I get "WARNING SUID file system/Library/Coreservices/Remotemanagement/ARDAgent.app/Contents/MacOS/ARDAge nt has been modified

My computer is shutting down before fully booting up. I am running the disk utilities program and have this message: Error: Disk Utility can't repair this disk . . . disk, and restore your backed-up files. Can anyone suggest what I should do next?

So, you can't Install OSX to the external?
Or you can't boot from it when you do?
You're not the only one wondering... I'm reminded of the Goose that laid the Golden Egg story.

External Hard Drive Disk Utility Can't Repair the Disk

Hi,
I have a Seagate 1 TB Backup Plus Drive which was working perfectly fine until I plugged it into a USB hub. It detected it while in the hub and I was able to get files off of it, but when I ejected it from the hub and put it back into the USB slot on the computer it was not detected by finder. It shows up in the disk utility and I clicked verify and repair and it says:
Verify and Repair volume “Seagate Backup Plus Drive”
Checking file system
Volume repair complete.
Updating boot support partitions for the volume as required.
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Is there any way to get this to work properly again? Or if not is there a way for me to recover my files on the external hard drive?
Thanks
I have a Macbook PRO late 2011 running OS X Mavericks.

Use a more powerful utility such as DiskWarrior, or a product such as those listed here.

Disk Utility reports minor repair required - how risky is this?

I was verifying permissions the other day and thought I'd check the hard drive as well. When running the verify hard drive it stopped with an error report as follows:
Volume Header needs minor repair
The Volume Macintosh HD needs to be repaired
Error the underliying task reported failure on exit. 1HFS volume checked. Volume needs repair.
The Macbook seem to be running fine. Should I run the repair or leave it. Someone once told me that if the Disk Utility fails to repair the problem it can leave the disk unusable. Any truth in that?
Thanks

Directory structure issues can lead to freezing, general slowness, startup issues (computer may not startup all the way), Applications or files may not open.
It is usually suggested to repair the disk with Disk Utility that came with the computer or a disk utility that is compatible with the operating system that you are using.
Here are some articles from Apple's knowledge base. Some are technical:
http://docs.info.apple.com/article.html?artnum=302411
http://docs.info.apple.com/article.html?artnum=13628
http://docs.info.apple.com/article.html?artnum=7565
http://docs.info.apple.com/article.html?artnum=19516
Directory structure issues usually are not HW issues, but is the way the computer or OS, stores/sorts information on the Hard drive.

Disk utility can't repair a partition on external hard drive

I have a 1TB Western Digital external FW drive that's only a couple years old (2 or 3, probably). I have it split into partitions, one of which I'm using for Time Machine. The non-Time Machine partition checked out fine with DIsk Utility, but when I ran Disk Utility on the Time Machine partition, I received this message:
Disk Utility stopped reparing "Time Machine." Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Does this mean the drive itself is failing? I erased the Time Machine partition and recreated it through Disk Utility, and then I verified it. Everything checked out okay, but I want to make sure, especially since I'm hosting my iTunes music in the other partition (it's backed up to a 2nd external drive, so if the drive does die, at least I don't lose everything).
Before this problem happened, both partitions dropped off the Finder and the light on the drive went off. I unplugged the drive and plugged it back in again a couple times, but nothing happened. Finally, the light went back on after plugging it back in for the 3rd or 4th time, but I'm wondering if the drive could be going bad, which would surprise me since it isn't very old.

Possibly, but not necessarily. The File System on the disk was so badly corrupted that Disk Utility couldn't fix it. That might indicate a problem with the drive. It's not unusual for consumer-quality (ie, inexpensive) drives to fail after 2-3 years, although many will run for several years. It's a bit of a crapshoot.
Before this problem happened, both partitions dropped off the Finder and the light on the drive went off.
Whatever caused that is another good possibility -- if a drive is improperly disconnected, OSX can't "close it out" properly, and that can cause damage to the file system. Sometimes Disk Utility can fix it, sometimes it can't. And sometimes heavy-duty 3rd-party disk repair apps like DiskWarrior can fix things Disk Utility can't.
A power dip or spike could have caused it, or an overheated electronic component, etc. If it has it's own power supply, be sure it's on a good (ie, not cheap) surge protector or U.P.S. system.
Otherwise, keep an eye on it. If you don't have "secondary" backups, this would be an excellent time to get another drive for that purpose. See #27 in Time Machine - Frequently Asked Questions for some suggestions.
Bottom line: personally, I'd not trust my only backups to that drive.
(But then, I'd never trust my backups to any single drive, no matter how new or high-quality.)
