Disk Utility "Verify Disk" Grayed Out

Disk Utility's "Verify Disk" button is always grayed out on my iMac 10.4.11.
It is not grayed out on my iBook 10.4.1.
Both machines have Disk Utility Version 10.5.6 (198.12).
Any ideas?

Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot.
The usual reason why updates fail or mess things up, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates.

Time machine disk grayed out in Disk Utility - back up not working

The disk does not show in Time Machine.
In Disk Utility it shows but is grayed out. Tried to repair disk. Got message that disk cannot be repaired. Tells me to back up and erase the disk. Not sure how to back it up if it is not being recognized. Disk Verify says the volume is corrupt and needs to be repaired. But Repair Disk doesn't work!
I can go into Time Machine and shows me one entry -- the one from the last successful back up.
The disk is a WD MyBook. Map scheme GUID Partition. Do you think the reformat will work? Is there a way if I can tell if the disk is bad? Tech Tools for Apple Care doesn't recognize the volume either.
Any ideas?

It turns out the fix for this was to just then remove the Aperture library from the exclusion list. Once I did that Time Machine did a massive 200GB backup of my entire Aperture library and everything is running fine since.
No idea what caused the problem in the first place still.

Why is repair disk grayed out for Time Machine backup?

I am running Mountain Lion on an old MacBook Pro 15" Late 2008 with 6GB ram.
I am using (or trying to successfully use) Time Machine with a 2TB Time capsule (about 4 months old). I also have an old WD 500GB usb drive attached to the TC.
After being away on vacation for a week or so, I got the dreaded "Time Machine need to create a new backup" message.
I have searched the great Pondini's very helpful website and I've got to the point of using disk utility to try to repair the backup.
After running disk utility it gave me this message:
Invalid sibling link
The volume Time Machine Backups was found corrupt and needs to be repaired.
Error: This disk needs to be repaired. Click Repair Disk.
Well, I can verify the backup, but the Repair Disk button is grayed out.
Pondini,
I need your help.... again.
Thanks,
Dean

That message means what it says: Time Machine will not back up to that sparsebundle again.
As detailed in #C13 of Time Machine - Troubleshooting, you may be able to recover selected files, or even restore an entire backup, but that's it.
Well, I can verify the backup, but the Repair Disk button is grayed out.
OSX does that when it's already determined it can't repair it.
If you have DiskWarrior, it might be able to fix it, but I doubt it. I don't recall any posts saying it did. If you don't, I'd not recommend spending $100 ro find out.

How can I "repair disk" with Repair disk grayed out?

My external back-up has been complaining of late, Time Machine can no longer access it, and now, after trying Verify Disk, it stopped that process and told me to use Repair Disk.
Repair Disk is grayed out. But my WD unit isn't even six months old.
Where do I turn?

I found a Grab of part of the response from Verify Disk.
If that's impossible to read, (1) blame Apple and (2) let me know -- I'll punch it up.

I just updated to Mavericks and now I can't get my toshiba external HD to show up. It appears in Disk Utility but not in my finder. In Disk Utility it is grayed out and will not allow me to mount. Ive verified and repaired it. Nothing!

I cant take it anymore. Pleae someone help me. I cannot erase my HD becasue it has all of my pics for my kids and all of my movies school work. I need this fixed please

Hi Liz,
Sorry to hear you are having a similar problem. Last night I went to the tool bar at the top of iphoto, clicked on "File", then clicked "Browse Backups" in the drop down menu.    I have an external hard drive that is set up to Time Machine.   The Browse Backups opened the iphoto pages in the Time Machine. I selected a date one day ahead of the day I performed the now infamous update, and it showed my iphoto library as it had existed that day.   I then clicked "Restore Library" at the bottom right corner of the Time Machine screen.   Roughly 2 hours later my iphoto was back to normal.   When I opened iphoto there was a message saying I need to upgrade my program to be compatible with the new version of iphoto(version 9.2.1). I clicked "Upgrade" and within seconds it had done whatever upgrading it needed to do.
The only glitch in the restoration was that it restored the library as it appeared last week, so I no longer had photos I had imported this past weekend.   I simply went back to the Browse Backups in the drop down menu, when Time Machine opened I selected the page showing my pictures from this weekend and again said to Restore Library.   Roughly 45 minutes later the library was restored including the most recent photos.
I am now a happy camper.
I don't know if any of this will be of help to you because your email says you are having trouble with photos imported after the upgrade was performed.   Have you had any pop up notices when you first open iphoto, that tell you you need an upgrade to be compatible with the new iphoto?     If so have you clicked "upgrade"?
Good luck Liz, if you have Time Machine running as a back up to your library, maybe you wil be able to get help there, by following my instructions above.   Otherwise,   good luck with your investigations.   I'd be interested in hearing how you make out.

Disk Utility - Verify button greyed out.

[IMG]http://img.photobucket.com/albums/v43/pupspals/DiskUtility-noVerifyDisk.jpg[/IMG]
I'm running 10.4.9 & have everything updated except for the recent Pro App. I wanted to verify my disk before installing this when I noticed that the button was greyed out! I click on my hard drive, I click on my disk & it's still greyed out!
Any ideas?
Thanks!

I never use the Verify Disk feature from my boot volume which can report a problem that doesn't exist when later running Repair Disk via Disk Utility when booted from your install disc.
If a problem is reported when selecting Verify Disk via Disk Utility from your boot volume, you will need to do the repair when booted from your Tiger install disc anyway so best all around to go ahead and do this from the outset, select your language and at the Installer menu bar, navigate to Disk Utility. Select your boot volume in the drives and volumes window which is usually Macintosh HD and under the First Aid tab, select Repair Disk.
Selecting Repair Disk does a Verify first anyway and if a problem is discovered attempts to make the repair so running Verify Disk first or instead of Repair Disk only each time does not gain anything.

Disk Utility: First Aid: "Repair Disk" grayed out when i select the HD

I'm getting the flashing question mark folder icon at startup and my Mac never does start. I'm trying to run through the repair suggestions on this forum and on the support pages but I can't do much of anything with the disk utility. (I've done the reset PRAM step and I've tried reselecting a startup volume both with the startup manager --HD wasn't shown as an option-- and by holding down "X" on startup... neither helped.)
Under first aid, verify disk permissions, i get the "no valid packages" error message. But "Verify Disk Permissions" is the only button available to me when I select my internal hard disk. The support pages say to "Repair Disk" but I can't select that option.
I've tried to reinstall the OSX from the CD, but when the installer asks me to select a destination volume, nothing is available to select.
I am running version 10.4.something at least. My CD is the one that came with the computer a couple of years ago. I have one of the early Intel Macbooks.
I have an appointment at the Genius Bar after work tonight but I'd love it if I could fix this baby sooner.
Am I hosed?

OK- Try a Single User boot- hold command +s while starting, and try and repair with fsck.
-Startup in Single User mode.
-At the command-line prompt, type */sbin/fsck -fy*. Press Return.
fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
*The volume (nameofvolume) appears to be OK*
-If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
*FILE SYSTEM WAS MODIFIED*
Important: If this message appears, repeat the fsck command again, until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
-When fsck reports that your volume is OK, type *reboot* at the prompt and then press Return.
-Your computer should start up normally and allow you to log in.
Resolve startup issues and perform disk maintenance with Disk Utility and fsck

Verify Disk under disk utility is grayed out

When I go into first aid in disk utility, and click on my system drive, the verify button is grayed out.
If I remembered correctly, I was able to verify my system drive before.
Any idea?
Thanks!

Hi, and a Warm Welcome to the Power Mac G5 Forum!
You could check that Journaling is enabled on the drive - in Disk Utility > File menu > Enable Journaling

Verify/repair permissions grayed out in disk utility

I recently replaced my main hard drive and now when I go into Disk Utility the option to verify and repair disk permissions is not available on the other drives that were in the machine before the upgrade
I am thinking it's a permission issue but not sure what needs to be set to fix it

No problem. It puzzled me for a while. Now I check it every time I format a drive since DU doesn't correctly set the permissions needed. It's a pain that when you clone one startup drive to another, say for backup, and erase the destination in advance that the drive's ownership and permissions will be wrong. Then you try repairing permissions like the OP did and find those options are grayed out, and you are staring at the monitor trying to figure out why. PITA.

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 says repair needed but repair grayed out

I ran a disk utility verification, which indicated that repair was necessary. However the repair option was grayed out. How do I effect a repair?

Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. 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 your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

Flashing Folder with Question Mark, Disk Utility Grayed Out

I was working on my macbook pro when it appeared to freeze, so I manually shut it down by pressing the power button. When I pressed it again to restart the computer, the restart "chime" sounded, and a flashing folder with a question mark appeared shortly after. The folder flashes for a few minutes, and the macbook turns off again. After consulting the internet, I restarted while holding command+r, and the computer told me to reconnect to the internet, select a language, and so on. When I reached the menu giving me choices for how to recover my information, I discovered that there were apparently no time machine backups recognized and when I tried to use the "first aid" option in Disk Utility, all of the action buttons are grayed out when I select the drives (I'm running OS X Mavericks) at the left, including the "Verify" option at the top. Is there anything I can do? I really would rather not restore a new version of OS X to preserve my information.

Thanks for the response. When I clicked on the option to reinstall, the window asking me to select the disk where I would like to install Mac OS X presents no options. There's just a blank white box with no other messages or prompts.

When I turn on computer just get envelope with ?, so did an internet recovery. If I select reinstall mac os x (it is nac os x lion), it is blank where you pick where you want to install, nothing to pick. If I go to disk utility, to the left it lists "mac os x base system", but if I click on any of the tabs it is all grayed out.

Your HDD needs to be replaced. It apparently is dead.
Ciao.

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.
