Disk Repairi Error

i'm not able to empty the trash so i tried disk repair. it fails with the following errors.
disk utility stopped repairing macintosh hard disk because the underlying task reported faliure on exit
invalid sibling link
volume check failed

Disk mounting while booted from a CD happens via a "RAM disk" and I don't recall off hand how it works, plus I'm not sure what utilities are present on an installer disk (ie. 'mount', 'mount_hfs', etc - it would probably be easier just to reboot.
If the "RAM disk" is actually called "/Volumes", and if the CD contains 'mount_hfs' or 'mount' in the usual places, then it should be possible to mount a disk that has been un-mounted using 'umount' by using either of:<pre>/sbin/mount_hfs /dev/diskXsY /Volumes/diskname
/sbin/mount -t hfs /dev/diskXsY /Volumes/diskname</pre>Of course, use the correct values in place of "diskXsY" and "diskname" as it applies to your situation. But seriously, it probably would be easier just to reboot.

Time Machine Disk Full and Disk Repair Errors?

I have an external USB drive connected to an iMac that I use for TM backup. I received severel disk is full messages today, and the iMac told me that is was going to delete older backups and that's fine. But, I also have a MacBook backing up through the network (Airport) and that the Macbook was giving me the backup disk is full errors, and now it's saying: Time Machine Error: The backup volume is read only. To select a different volume...etc. And now that error is followed by a Disk Repair error saying the disk needs to be reformatted? Any help would be appreciated.

I'm sorry to see that no one has replied to Christopher in the two months since his post.
After 5 weeks of successful back ups I am now getting this same TM Error followed by Disk Repair error. The first time it happened I moved the sparsebundle and let TM start over. That worked fine and lasted one week, but now the errors are back. Today I tried repairing the sparsebundle in Disk Utility and it too failed with the following:
Invalid key length
Volume check failed.
Error: Filesystem verify or repair failed.
The same Airport attached 500GB HD has been receiving TM back-ups from another Mac for over a month with no incidents, and houses my iPhoto library along with a hundred gigs of other stuff.
The other Mac connects exclusively via ethernet. My PowerBook uses ethernet or wifi.
Something with my TM is corrupting the disk image. I'd sure like to figure this out.

How do i fix the disk repair error that pops up when i plug my iPod into my computer?

every time i plug my ipod into my mac a "Disk Repair" error pops up. how do i fix that?

Try a low level reformat of your iPod using Disk Utility and the instructions in this article.

Disk Repair Errors

I generally run the Disk Repair Utility when I install new software due to some software not abiding by the rules. When I did this a few days ago I came up with the following errors:
Warning: SUID file "System/Library/CoreServices/Finder.app/Contents/Resources/OwnerGroupTool" has been modified and will not be repaired.
Warning: SUID file "usr/bin/lppasswd" has been modified and will not be repaired.
Group differs on "private/etc/cups", should be 0, group is 26.
Permissions differ on "private/var/spool/cups/cache/rss", should be drwxr-xr-x , they are drwxrwxr-x .
In reading most of the postings regarding this condition, there was some hope that it would be fixed in 10.5.5. This is exactly when the errors occurred for me. As soon as I updated:
2008-09-17 13:39:38 -0400: Installed "Remote Desktop Client Update" (3.2.2)
2008-09-17 13:39:40 -0400: Installed "Digital Camera Raw Compatibility Update" (2.2)
2008-09-17 13:41:05 -0400: Installed "Mac OS X Update" (10.5.5)
The modification date on the Finder.app is 2008-09-17 13:41:05, same as the 10.5.5 update. Coincidence? Not likely.
The Disk Utility blurb that these are expected did not include the Finder.app error.

The only real problem here is that the programmers who designed
the Repair Permisions did not have the good sense to just run the
program, and then, when everything is done, simply report
"Repair Completed," or "Everything is A-OK. Nothing to worry about."

Disk Repair Error (Time Machine Partition)

For the second time, my Time Machine backup partition reports errors when I try to mount it (exists on my external hard drive via USB).
As soon as I plug in the USB external, I get this error:
*Disk Repair*
The disk "Backup" was not repairable by this computer. It is being made available to you with limited functionality. You must back up your data and reformat the disk as soon as possible.
I tried looking at it through Disk Utility, and I found "Repair Disk" grayed out, and when I click on "Verify Disk", the output is:

Checking Extents Overflow file.
Checking Catalog file.

Its worked fine for about 1.5 months since it did this last. My other partition on the external hard drive has always been fine.
Any ideas on the causes of this, or how to fix this aside from reformatting every 1.5 months?
Thanks in advance for your help!

I've had a very similar problem. When I tried to put Leopard on the first time, it wiped out my hard drive directory... Disk Warrior to the rescue. I then bought a brand new internal SATA drive and an external firewire drive for the back up. I formatted both drives and did a fresh install of Leopard on the internal. So far so good-ish. All other weird Leopard bugs and issues aside for now, I am now getting the error message that my Time Machine backup drive (which has been working fine) is irreparable and needs to be formated as soon as possible.
I have the back up drive partitioned and the non-Time-Machine-backup partition, that is the normal simply-storage partition is working fine. The Verify Disk Permissions, Repair Disk Permissions, and Repair Disk are greyed out in Disk Utility. Here's what I get when I Verify Disk.
Verifying volume “G5 Backup”

Checking Extents Overflow file.
Checking Catalog file.
Invalid catalog record type

Error: Filesystem verify or repair failed.

The volume Scratch appears to be OK.
Is a re-format of the back up drive my only option? How did this happen? and How can I prevent this from happening again?
Thanks!

Disk Repair Error

While repairing permissions on my 17" PowerBook G4, I decided to verify the drive as well. Drive Utility indicated the drive needed to be repaired, so..
I then came across this error message:
"First Aid Failed
Disk Utility stopped repairing DRIVENAME because the following error was encountered:
The underlying task reported failure on exit.
Checking extents overflow file.
Checking catalog file.
Keys out of order.
Rebuilding catalog B-tree.
The Volume DRIVENAME could not be repaired.
Error: The underlying task reported failure on exit."
My question is, will formatting the drive, reinstalling the OS and running updates fix this problem?
Thanks!

Thanks.
Moving on, I've encountered another problem. My startup disk does not appear when I begin the re-installation from from my PowerBook G4 installer Disk 1.
Disk Utility recognizes it, but I am not able to select this drive at the SELECT A DESTINATION step.
Where is my startup drive?
If I launch the Drive Utility from the Installer (booted off of the DVD) I can see this drive, but I still get the same error message while verifying/repairing.
Also, removing the installer DVD and restarting doesn't work - my startup drive is missing. The blinking folder icon with the question mark shows up.
What happened to my startup drive? How do I get it back so I can reinstall?
Thanks!

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.

Error in Disk Repair - PLS HELP

Dear All,
I have posted a message a week ago, about Error in Verifying Permission and Onyx Error -1. Then ~Bee (thanks for the suggestion, really appreciate it) replied and suggested me to try Disk Repair. I tried it this morning and the result was not very promising.
Below are the message:
Verify and Repair disk "Rich's HD"
Checking HPS Plus volumn.
Checking Extends Overflow file.
Checking Catalog file.
Invalid node structure
Volume check failed
Error: The underlying task reported failure on exit.
1 HFS volume checked
1 volume could not be repaired because of an error.
<--end of message-->
I also tried to verify Permission and it ran until 85% and it stopped without any activity until I 'stopped' the verification.
I really hope my HD is not up to something bad. What I have done were only installed CS3 (only installed Photoshop and Illustrator) and it was running fine until recently.
If anyone has any idea or suggestion, please let me know.
Thanks a lot!
Worried,
chityc.

The reason you need to boot from the DVD and run Disk Utility is that an active, mounted disk cannot be repaired.
If you want to save some time (bypassing the need for the DVD) on this and don't mind using single user mode (type a command similar to DOS on a PC) then do the following:
- Restart the Mac and hold down the Command (Apple) and 'S' keys simultaneously. This will put you into what is known as 'Single User Mode' (white text on a black background like DOS).
- At the prompt, type the command fsck -fy and press the 'Return' key.
- This will run through the same check/fix as Disk Utility.
- Repeat if errors are found (you can either retype or press the 'Arrow Up' key of the keyboard to revisit the command.
- If the error is resolved, type the command reboot and then press the 'Return' key. The Mac will reboot into its usual GUI interface.
Note 1: When in Disk Utility, look to the bottom part of the application window for the drive's 'S.M.A.R.T.' status. If it is 'Verified', your hardware is okay.
Note 2: I prefer to install a free app called AppleJack that gives you more functionality (disk check/repair, caches flush, preference checks etc..) in single user mode without needing to know the actual UNIX commands.
- If the error does not resolve (here or with Disk Utility from the DVD), your problem will require either a more powerful tool like DiskWarrior (commercial software) or backing up your present drive, reformatting it and re-installing.

Since hard drive restore, backup gives Disk Repair, Read-only errors

Hi all -
After a hard drive crash last week, I restored the new HD using my historically reliable wireless Time Capsule (TC) with Time Machine (TM). But ever since, backups have ceased to work. Now, TM spins for about an hour before returning the following errors in sequence:
(1) DISK REPAIR: "The disk 'Backup of [my name] Macbook' was not repairable by this computer. It is being made available to you with limited functionality. You must back up your data and reformat the disk as soon as possible."
(2) TIME MACHINE ERROR: The backup volume is read only. To select a different volume, open System Preferences and choose Time Machine."
I very much doubt there is an actual problem with the TC disk itself; my wife's iBook G4 continues to backup to it without any problem whatsoever. Related threads have suggested:
a) doing clever things with Preferences, such as deleting the com.apple.TimeMachine.plist file and re-booting. However, for some reason (perhaps related to the source of the problem?) I have no such file...
b) using Disk Utility to re-format and/or re-partition (these terms mean little to me) the TC disk. But my Disk Utility doesn't see the TC. (Perhaps related, I no longer actually see the little backup disk icon on the desktop.) And as I've said, I doubt very much it's the TC disk itself that it is the problem.
I have of course tried re-booting everything, as well as un-mounting and re-mounting the TC: Computer, heal thyself! No luck.
Any guidance is appreciated...
(PS If there's a log file I should post that might help with diagnostics, just let me know where to find it.)

I have suffered the same error messages, but without a hard disk crash before it.
I copied the backup-file from the TC to a separate drive, erased the TC, re-installed it, copied the backup-file to the TC en re-initiated TM only to be welcomed with the 'The backup volume is read only'-message again.
Beats me why this happened. Most frustrating part, however, is that I am not able to restore from the backup-file. Any suggestions are highly appreciated!

Disk Repair Utility Full Disk Error

Today, my MBP froze, as in it no longer responded to keypresses or moving the mouse, so I held the power button until it powered off. Whenever I try to power it back on, it comes up with the apple logo on a gray screen, and a progress bar briefly appears beneath the apple logo, flashes a few times and dissappears, then the computer turns off.
By running the disk repair utility from the OSX install disk, the OSX partition of my hard drive needs to be repaired. When I try to repair it, it gives me an error saying that the disk is too full to do a repair on (I probably have ~10GB free, so this makes sense), and I need to wipe my disk and reinstall OSX .
I have windows installed via bootcamp and I can still boot into that and see my contents of the OSX partition (e.g. I can play my music, watch movies, open documents all of which are on the OSX partition, I just can't boot to it.).
Although probably unrelated, I've run the diagnostics, and everything came up okay. I've also tried holding shift during boot (trying to get OSX into safe mode) and holding command-option-P-R (clear the PRAM) during boot, neither of which helped.
My current strategy is copy a lot of data off my OSX partition from within my windows partition to an external HDD, in order to free up space on my OSX drive, so that hopefully disk repair can do its job. Does anyone know if this will work, or if not, can anyone recommend an alternate work around?

Backup your files, if possible. Your only recourse is to reformat the drive and reinstall OS X. Do not copy or backup files from Windows. If at all possible boot from another drive like your external HDD by installing OS X on the external drive (unless it is already a bootable drive.) You can then copy your data from the faulty OS X volume before erasing it.
You should never permit your free space to drop so low. One should maintain 10-12 GBs or 10-15% of the volume's total capacity, whichever is greater.
Since this problem will likely recur I suggest you consider just replacing the drive with one that is considerably larger. I would also be sure to arrange to maintain a bootable backup on an external drive in case problems such as this one occur.

Repair Disk Permissions Error: The underlying task reported failure on exit

Hi All...
any idea about this error when trying to Repair Disk Permissions using "Disk Utility" :
"Error: The underlying task reported failure on exit."
No repair is made at all! It just stops right after being launched
It happens either when booting on the Leopard CD or on external FW drive...
Cheers guys!!

Someone help!!!
It sounds as if you transferred the errors when you migrated your files from the G4. Something in that old filestructure that is not right. It might be the ownership of a single file somewhere.
Have you considered DiskWarrior?

Disk utility errored out when attempting to repair Macintosh HD

My iMac suddenly got really slow this morning, occasionally freezing for a few minutes. I ran disk utility to repair permissions, MacJanitor and then restarted to no avail. Then I started up using the original install CD (10.4.4), ran the hardware test and passed, and attempted to repair the disk with Disk Utility. I got through the first steps, but then when checking the Catalog File, I got the following error:
Invalid Node Structure
Volume Check Failed
Error: Underlying task reported failure on exit.
Before I exited, I repaired disk permissions again, and this time it found a bunch of bad permissions...when I restarted, system was still slow, so I know I still have a problem
Any suggestions on what to do next?
Thanks,
Eric

Try that disk repair a few more times, you never know!
But more then likely it won't be able to repair an Invalid Node Structure. That's a pretty serious error.
If Disk Utility can't fix it, you'll need a more robust utility for the repair. I would recommend DiskWarrior. It is the best at directory repairs. It rebuilds then actually replaces your old directory. I feel every Mac owner should have a copy. Make sure you get the disk so you can boot up on it to run repairs. You can also install it on another drive and run it from there to repair this one. DW works faster that way.
I use DW once a month to try and catch errors in my system from getting too far out of hand.
If you have a good backup, hopefully a clone of your system before you had issues, an Erase and Install will also rid you of this issue. But, beware! You will lose everything on the drive with this procedure. Let us know if you need help with that!
Cheers! DALE

Is anyone able to help with a Mavericks to Yosemite upgrade error: Disk Repair Failed?

I upgrade my Mavericks OS on my MacBook Pro to Yosemite this morning and it's stuck on "Installing on Hard Disk" but then produces errors in the Cmd+L log such as:
+ Disk Repair failed. Will attempt to wait for kextcache
And then it fails suggesting I restart or change to another startup Disk, but when I do, it says "You can't change the start-up disk to the selected disk. Startup disk could not gather enough information on the selected disk."
Does anyone know of any resolution?
Kindest Regards and pleads

I figured out my problem. If yall are having the same issue, don't use (Quick) format, use the complete format option.

Repair Disk Permission Error Message

I routinely run Disk Permission Repair through the DU as part of maintaining my Mac (I can't help it - I was once a Windows user :)). Today when I ran this on my primary drive, I received this error:
Warning: SUID file "usr/bin/quota" has been modified and will not be repaired
I checked previous posts and this ISN'T listed as one of the disk repair messages I could safely ignore.
Any ideas as to how to fix this and how serious an error this is?
Thanks.
