Disk Utility can't repair or verify?
Hi, my 12 G4 powerbook is running fine except the fan is on nearly all the time. I thought I'd try to repair (or verify) disk permissions to see if that might possible help. But every time I run it on the HD, it just spins for maybe 10 min then gives an error message indicated failure. Why can't Disk Utility find the permissions? The disk otherwise works fine. There's no partition and i'm the only user.
Thanks.

HI Wayne,
*"thought I'd try to repair (or verify) disk permissions to see if that might possible help. But every time I run it on the HD, it just spins for maybe 10 min then gives an error message indicated failure."*
You can repair disk permissions from the Disk Utility application already on the drive. (Applications/Utilities) but I doubt that's the issue here.
Try resetting the PMU, *(not SMC)* instructions here: http://support.apple.com/kb/HT1431 Read the article carefully before doing this.
Can you boot from your restore disk? Restart your PBook while holding down the C key, pressing the power button and inserting your restore disk all at the same time. An Installer window will open, but do not proceed with any installations. Instead, from the Menu Bar, select Utilities > Disk Utility. In the Disk Utility window click First Aid, and then click Verify. If Disk Utility reports errors, click Repair. When Disk Utility is finished, from the Menu Bar, select Utilities/Startup Disk. Select MacintoshHD 10.x.x and click Restart.
If Disk Utility cannot repair the disk, there are several good disk utilities to look at. One is DiskWarrior and the other is TechToolPro.

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.

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 can't repair TM backup disk
Hello all
Recently, my external backup disk (a 750 GB WD My Passport) that I use with Time Machine has been acting up. At first, it wouldn't show up on the desktop, but was being recognized in Disk Utility (with the "Time Machine Backup" partition greyed out). After multiple restarts and unplugging/replugging the hard drive, I finally got to be properly recognized, i.e. it showed up on the desktop with the proper Time Machine hard drive icon. So I thought the problem was gone and started a routine backup. However, Time Machine returned an error:
"Unable to complete backup. An error occurred while creating the backup folder."
I search the forums, and followed the advice here: http://web.me.com/pondini/Time_Machine/C10.html
I tried repairing the disk, but DU couldn't repair it:

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.
So now I'm still following the advice on the above mentioned page by posting on here. Any help at all would be greatly appreciated. I am using a 2010 15in 2.66 i7 MBP, if that makes a difference, although my guess is the problem's with the harddrive itself. I think there may have been one time about a month ago when Time Machine stopped responding (or something like that) which forced me to pull out the harddrive, possibly corrupting the data. But I'm not sure, and I do recall making at least one successful backup after that. Well, actually TM confirms this: "Latest successful backup: 5/27/11 at 11:51 PM". So I have no idea what's going on. Again, any help would be appreciated.You can't tell what's corrupted or where. Time Machine backups have a very complex structure, all linked together. So, you can often do new backups, or restore individual items, or even entire backups, as long as you don't stumble over the damage.
There's a chance a heavy-duty 3rd-party disk repair app, such as Disk Warrior, can repair them. It's about $100, and probably a good investment for the future, but there's no guarantee it can fix them.
If not, or if you don't want to spend the money, your only option is to erase the disk and let Time Machine start fresh.
It sounds like you may have other data on it; if that's in the same partition, that's not a good idea. This is a good time to copy the data off, erase the disk, and make 2 (or more) partitions on it, so Time Machine has its own, exclusive space. See #3 in Time Machine - Frequently Asked Questions for details and instructions. -
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.Brad Cook wrote:

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.) -
Disk Utility can't repair this disk
I have been having trouble booting. It started when I connected a router to it. It seemed to eat up the free disk space and I only have 77 MB left or something around that.
Anyway, I tried deleting files with command-s commands, and it worked one time and it freed up 2 GB of space. I restarted the computer and when I tried to start it up, it still got stuck in the gray screen with the whirly thing at the bottom. I checked the space and it was 77MB now.
I decided to boot from the Install Disk (Snow Leopard 10.6.0).
I checked Disk Utility first and verified the disk. It came up with the message:
"Error: Disk Utility can't repair this disk .... disk, and restore your backed-up files."
What should I do now?
I have the Mac HD volume on backup already so I don't have to do the back up stage.
Should I erase the disk while I am in Disk Utility?
And format it to Mac OS Extended Journal?
And then install the operating system again?
Thanks.To answer your questions, first, some other options...
If you fill your disk up that far, you are going to have problems. Don't ever do this, 10% is a bare minimum, you may need even more, depending on the size of your disc.
I have seen before where a disc repair utility couldn't perform its function simply because there was not enough slack space available on the drive. While I have never seen this with disc utility, it is possible that the disc is repairable as-is, if you could just free up a couple more gigs of space first.
Secondly, you could also try Disk Warrior, or to a lesser extent, Techtool Pro, or even iDefrag. I have personally never had Techtool Pro fix anything that Disk Utility or Disk Warrior couldn't fix, so I hesitate to even mention it, but I have had Disk Warrior and iDefrag clear up problems that Disk Utility either couldn't detect, or couldn't fix.
If you are still in dire straits, you should re-partition the drive using disk utility. This is the safest route, then go from there.
good luck!

Your backups may be hopelessly corrupted, but there's a chance an (expensive) 3rd-party Disk Repair utility might be able to fix them. For the moment, eject and disconnect the TM drive and try to repair the internal.

Partition errors - "Disk Utility can't repair this disk"
I partitioned my external 1TB WD HD into two drives (950GB + 50GB) using Disk Utility (OS X Mavericks 10.9.1). However the 950GB partition will no longer mount. It is recognised in Disk Utility, but grayed out. "Verify Disk" and "Repair Disk" in Disk Utility lead to the worrying error message "Disk Utility can't repair this disk."
From the Disk Utility logs, the initial partition was successful:
Partition 1:
Name: “Media Centre”
Size: 948.13 GB
File system: Mac OS Extended (Journaled)
Do not erase contents
Partition 2:
Name: “Media Centre 2”
Size: 50.03 GB
File system: Mac OS Extended (Journaled)
Do not erase contents
Mounting disk
Partition complete
Afterwards, I changed the name of the second partition “Media Centre 2” to "BOOTCAMP" (I was going to try to install Windows 7), but then changed my mind and tried to remove the second partition. At that point the log gives the error "Mount of “Media Centre” failed".
Partition 1 ("Media Centre") now seems to be in limbo, stuck as 950GB, and "Verify Disk" and "Repair Disk" in Disk Utility lead to the worrying error message "Disk Utility can't repair this disk". Also in Disk Utility, Partition 1 ("Media Centre") now has the format classification "Mac OS Extended" rather than "Mac OS Extended (Journaled)".
Any idea how I can get my hard drive to mount and get the data back?In Disk Utility select the Top most entry on the left, the drive model and or manufacturer name and size entry, then click the Partition tab and Repartition it to your liking. If that fails the drive is bad.

Macbook Pro not booting after update. ''Disk Utility can't repair disk''. Help needed!
I have recently updated my macbook pro as I had some pending software updates. I left it to do the job over night and the next day I noticed it was not letting me sign in to my account session as usual.
I restarted the computer and ever since then when I boot it, it just shows the apple grey screen with a bar that loads to about a 3rd and then it turns off again. I have contacted apple but they were unable to help me with this.
So far I have tried to:
1. Re-install OS X 10.8 - but it says the disk is locked or OS X cannot be installed on Recovery HD.
2. Verify and Repair the disk and I errors but it cannot fix them. Some are:
'invalid leaf count''
''missing thread record''
''incorrect number of file hard links''
''overlapped extent allocation''
and it finally says ''the volume Macintosh HD cannot be repaired'' Error: ''Disk Utility can't repair this disk.. disk, and restore your backed up files.
I would like to know a way to back up my files so that i can completely restore the disk without any data loss as I havent backed up for a while!
If anyone has any solution to this issue it would be much appreciated!I just ran the Disk Utility, and cannot very disk. It gives me an error message;
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
and when I run the repair, this is the message:
The volume GERRARD could not be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
1 volume could not be repaired because of an error
Repair attempted on 1 volume
1 volume could not be repaired
Prior to running Disk Utility, I have already tried DiskWarrior, and could not repair my disk. Anyway I can fix this problem??? Formatting the disk would be my last option (though I am unsure if it will fix the problem). Any advise would be greatly appreciated. Meanwhile, I will continue to back up my file, and delete unused data and try to run it again.
Thank you all very much for any input.
Cheers,

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?
Imac :OSX 10.9.4 , 2.7 GHz Intel Core i5, 8 Gb Ram.Nico,
Did you find a way?
This just happened to me too.

Can I fix a disk with this message?
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.Some problems can indeed be fixed this way. But working from Recovery_HD or Disk Warrior DVDs and working in the restricted environment those provide can be difficult. You can literally spend days working on this problem (while your regular work is unavailable) only to discover the old drive is unsalvageable.
There is no way to know up front whether you are facing a major Hardware failure or a minor software glitch, or something in between. Often you are forced to work from the drive you no longer trust. I continue to recommend you do this work from a different, fully functioning Mac OS X booted from a different drive.
If you have had the foresight to (as The hatter often recommends) clone your virgin install onto another drive for use in such situations, you will be able to recover from such problems in record time. If not, my previous recommendations stands:
Buy a new Drive. Or two. Install Mac OS X from scratch on a new drive, and get your Mac running again. Later, you can use the full power of Mac OS X to attempt to rescue your data, if needed. Then Zero the old drive, to see if it can hold data again reliably.
If the old drive eventually provides some needed data, and is salvageable, Merry Christmas. -
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. -

You can't have received an error message "Disk Utility can't repair this disk...disk, and restore your backuped-up file." since that is pure gobbledegook and isn't even good English.
What may have happened is that
(a) your hard drive has become so full that the operating system can't find any space in which to.... operate.
(b) as macjack says, it has crashed - possibly as a result of (a).
(c) you have been allowing Time Machine to back up to your internal hard drive instead of to a backup disk, which has caused (a) to happen.
