I was using my MacBook suddenly it hanged and i restarted it by pressing power button. After that when it restarted i got startup problem with spinning gear. Then, to fix it i used Disk Utility. when it stated to repair the disk it was showing 33minutes needed. but after waiting 25minutes it still shows that 33minutes remaining. no wroking progress was seen. then i stopped it and restarted my macbook by pressing power button again.

My Macintosh HD partition is damaged and the disk utility failed to repair it

I cannot boot anymore after I tried to repair the disk with Disk Utility after my Mac became very slow.
This is the second time it happened to me in a week with the same symptoms. When I try to boot, I see a gray screen and the computer just stops
When I use the recovery partition, the disk utility fails to repair the disk, stopping after failing to fix the catalog file.
I started to use TM to backup my data after erasing the disk and reinstalling Mountain Lion but I wonder if my hard drive is damaged because the same problem happened twice. (Thanks TM for keeping my data safe this time)
Any advice or ways to fix that once and for all ?
PS : The worst is that i can still boot with Bootcamp to Windows, not very useful though

Since your Recovery HD and Windows partition work fine, the problem is located in your Macintosh HD partition and I very highly suspect it's bad/failing sectors that's to blame for your troubles.
This can sometimes occur if the computer was moved while the hard drive was in operation, else sectors fail all by themselves, or if the drive is having mechanical issues, which you problem will continue no matter what you do.
This time when you use Recovery > Disk Utility to erase the Macintosh HD partition, use the middle secure erase option, not the far left or right options (the right will work also just take a really long time)
What your doing is with the middle secure erase option is called a "Zero" write, which Disk Utility will write 0's over all the bits in that partition. When it's done it will read it back for confirmation and when it does so, any bits that are failing will be mapped off by the drive. Hopefully this will resolve the issue without needing a drive replacement.
Once that is completed, reinstall OS X from Recovery, any programs from original sources, files only from backup and your problems hopefully should disappear.
What happens is if your data gets corrupted on the boot drive by failing sectors, it gets transfered to TimeMachine (or to bootable clones) and when you restore your right back to square one. So it's important to rule out that possibility with original installs of OS X and third party programs.
If your problems continue, then it's possibly a problem with third party at boot kernel extension files, (and the catalog problem was yet another one) so to solve this you need to make sure all your third party software is updated and works with your current OS X version.
A trick is, if you get gray screen at boot time, is to hold the Shift Key while booting the computer, this will disable a lot of things and allow you to fix the third party software issue.
What I suggest you do is have multiple backup systems, including hold option key bootable clones, this way if your TM drive gets corrupted you can go back in time to a saved state on the clone, restore that and then your files from the TM drive.

Wife about to give birth and Disk Utility failing to repair HD.

Good morning. Starting last night I began having serious issues with my 2007 20" 2.4ghz iMac. I hope someone can help before I employ the "nuke" option.
First a little background. My wife is about to give birth to our second child. I have several in-laws in town and my house is a wreck. So, last night I thought it would be a great time to upgrade my iPhone 3G to iOS 4. I am not implying that updating my phone caused the problems with my iMac but they started about 30 seconds after pushing the "Update" button in iTunes.
The phone did update to iOS 4 after about 3 hours of backing up but immediately the iMac started "hanging up" and the spinning beach ball appeared for minutes at a time. late last night after my iPhone was functioning again, I went to bed.
This morning, the iMac was still responding very slowly and I was getting the spinning beach ball for even longer periods of time. So, I rebooted the machine and upon reboot the iMac would get stuck on the grey screen with the Apple logo and a spinning gear.
I tried all of the methods on this support document.
http://support.apple.com/kb/TS2570
It would not boot into Safe Mode.
I reset the NVRAM/PRAM.
I checked the power cables.
I removed all USB and perpherial attachments. (Including even trying to boot without the keyboard or mouse plugged in.)
After booting from the Install DVD and running Disk Utility, Disk Utility was telling me that almost the entire HD is available and that it could not repair the disk. I was receiving "Invalid Node Structure" and "Volume Check Failed" error messages.
So the last thing the support document suggested was a complete erase and re-install. I have been running Time Machine, but have never actually used it to recover anything, much less the 1000s of photos and 1000s of songs on the iMac.
Is there anything else I can or should try before pulling the plug and erasing the hard drive and praying that Time Machine has worked?
My very pregnant wife will have a heart attack if we lost everything on the computer. (I really am not joking that she might go into labor any second, her due date was last week.)
Thanks for the help and advice. I need it.

I know that I am a bother and asking alot of questions in quick succession, but I am hoping to take care of this before the baby makes its appearance.
I'm getting you have a lot on your mind right now, try not to not worry about it. Might be time to take a few deep breaths and try to relax.
If you have had your machine connected to Time Machine and it has been doing backups (I'm sure it has been) you have done everything necessary.
You can attempt an erase and restore however if your disk is dodgy or has failed at best it's a temporary solution. As I stated I would recommend taking it into an AASP and have it looked at.

Disk Utility failing to repair permissions after 10.5.7

I have upgraded to 10.5.7 and now I am unable to repair disk permissions. I have tried using disk utility and that does not work. It says it has completed after less than a second, when it says that it will take several minutes to read the permissions database. I need the permissions repaired as Final Draft will not work at all with the current settings.
I have tried repairing from CD but my Superdrive does not recognise the install disk. My other machine shows it as readable. I think that I have a problem with the Superdrive and am dealing with that as well.
I have also tried TechTool Pro 5 and that did not work either. Any suggestions?

Firstly I never delete anything in the library folder. So nothing that I have done.
My Library/Receipts folder is very small, the actual db folder is less than 400 kb and none of the pkg's is older than 16th of May 2009, and all of them are for programs that I reinstalled since.
I can wipe the drive and reinstall Leopard and restore the data via Super Duper. Is that practical as a way of rebuilding the database? Or shall I reinstall applications? I can use Amnesia to clear everything if that helps.

Disk Utility Failing to Repair HD

I ran Disk Utility this morning from the Tiger installer CD for the sake of general maintenance. It failed, returning this:
Verifying volume “Macintosh HD”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid node structure
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit
Disk Utility stopped verifying “Macintosh HD” because the following error was encountered:
The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
I've been searching the forums here, but most of the similar posts seem to dealing with newly-installed hardware, or a disk with a S.M.A.R.T. status "Failing" (according to Disk Utility's Log window). Neither of these is the case. Has anyone seen this before?

Disk Utility Failing to Repair External HDD

I was in the midst of running a Time Machine backup from my MBA (2012, running Mavericks) to an external HDD when I moved the laptop and managed to knock the cord out of the HDD, causing it to disconnect abruptly (the drive pulled away from the plug and hit the floor). Since then, I have been unable to to access the HDD at all, although the drive itself seems to be working, insofar as the light still comes on and the disc is spinning.
The HDD isn't visible in Finder. I can sporadically see it in Disk Utility - sometimes I plug it in and see nothing, sometimes it appears in Disk Utility after an extended period of time. It won't mount through Disk Utility, however I have managed to eject it a few times.
I have tried both verifying and repairing the HDD when it is visible; all attempts have ended in an error stating that I needed to backup the files and restore the drive. I've tried a number of tools to clone the drive, including Disk Utility itself, Carbon Cloner and a few others, but all have resulted in errors.
Is there any way I can salvage the data on the HDD? There are a few files on there I really don't want to lose...

Remove the drive mechanism from the enclosure and install it in another one.

Disk Utility Failed permission repair

Hi, Just recently I've encountered a strange and hopefully not serious problem.
When I try to repair permissions on the volume Macintosh HD, I receive the following error:
+Repairing permissions for “Macintosh HD”+
+ Reading permissions database.+
+ Reading the permissions database can take several minutes.+
+Error: The underlying task reported failure on exit.+
+Permissions repair complete+
Any help would be great.... thanks

Ok, here's the thing. I'm abroad right now and although I did bring my Install DVD, which I was required to present along with my computer in my two previous visits to the Certified Apple Dealer in my area--even though these were both purely hardware issues(busted fan on one occasion, failing optical drive in the other), this time when my issue is purely software based it seems that the DVDs didn't work properly; they mounted, but the finder showed no content in the window. I found this rather odd, because 2 days prior to visiting I was able to boot from the DVD and repair permissions on the drive in a vain attempt to resolve the software issue I was having which was that the system wouldn't boot. Anyway, this is usually no problem in the states, where I once called applecare and told them my Install discs weren't working and was promptly shipped a new set no questions asked.
However, they seemed to insinuate that this was too much red tape or work for them, although they didn't say this outright. Instead, they simply installed Leopard on my system I guess as a concession cuz I was originally running Tiger, and suggested that it'd be most efficient if I called for new Discs upon returning home.
SO, as you can see, I'm kind of in a quandry here with no Install discs from which to repair permissions.
Can you suggest anything, anything else that might work.
I even ran TechTool that came with applecare but that doesn't seem to have a permissions repair facility.
SO I'm in DIRE, DIRE need of some HELPFUL suggestions to circumvent this temporary hurdle, and would love to get this issue SOLVED.
I'm remiss to go back to the same dealer b/c not only is it a quite long and painstaking journey there, they seem to like to hold on to the computer at their leisure even when it's clear that there only plan is a fresh install. NOTE*** by no means is this a dis to them, as they are using their due diligence and adhering to policy, but I'll be back home in a coupla months and was looking for an alternative.

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.

Keys out of order, disk utility fails

PowerPC (?, whatever came just before Intel-based machines) iMac running 10.3.something failed to boot - hangs at "Logging into OSX" window but never gets there to log in. Booting from Install CR-ROM and running Disk Utility fails to repair Catalog. Booting in single user mode results in "Keys out of order (4, 51882)" "The volume Macintosh HD could not be repaired". Also tried to boot from Prosoft "Data Rescue II" CD-ROM but no help
Any suggestions to repair/recover?
Files all appear to be there - can navigate around in Unix and list them. Also have external Lacie hard drives connected (unconnecting does not resolve problem) - Would there be a way to cp or rcp some key files to these external drives to at least recover some?

Welcome To  Discussions jeff_st!
If all else fails, and you have access to another Firewire enabled Mac, you can also use Firewire Target Disk Mode, to backup as much data as possible.
Then reformat the HD, zeroing all data, and perform an Erase & Install.

Macbook Pro (mid 2012) Disk Utility can't repair HD

I have a friend's MacBook Pro in my possession that is not working and has not been used for about two months. After startup, seeing the loading bar, and getting stuck on the spinning wheel of death, I have taken some steps to try to get a boot into Mac OS X. I've reset the PRAM, tried booting in safe mode, and lastly tried to repair Macintosh HD via Disk Utility in the recovery partition. No luck. I get this message after an attempted repair.. "Disk Utility can't repair this disk...disk, and restore your backed up file".
This is a similar problem to this discussion thread here:
Disk Utility cannot repair Macintosh HD
However, in this scenario, my friend does not have any Time Machine backups and would like to recover his files.
I know that I can re-format and do a fresh install of OS X...but where does that leave me with file recovery?
Is it possible to retrieve the files at all?
Any help from the community would be GREATLY appreciated!
Thanks

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,
Matt

Macbook pro won't boot and when I tried to back up the hard drive I got "disk utility can't repair this disk backup as many of your files as possible"

My macbook pro froze and initially would not even recognize the power chord. Now it charges, but will not load up. I opened in in disk utility to try and back it up so that I could take it to apple to have it fixed but I got the message that said "disk utility can't repair this disk backup as many of your files as possible". How do I back up the files???

Nichelle215,
you can try the method described on this Apple page, in the “Instructions for backing up to an external hard disk via Disk Utility” section. (You can skip step 6, since you already know that your disk is irreparable.) Note, however, that this method is not guaranteed to work. Once you get your disk straightened out, you might consider purchasing an external hard disk for use as a Time Machine backup destination, so that a similar problem in the future won’t wipe out the only copy of your files.

MB pro shuts off after bootup chime, hd damaged/volumeheader related - disk utility can't repair - how do i recover/backup my files??

Hi guys,
My macbook pro late(dec) 2011, doesn't boot up anymore, it just turns off after the chime (whilst a gray bar is loading a bit and then the MB shuts off)...
This all happened after I upgraded to mavericks, safari and chrome were spontaneously shutting off, my macbook kept restarting (all after recommended app store updates), it had kernel panics etc. Last night after an update it just wouldn't boot up anymore! Pff.. what should i do?
Disk utility can't repair the damaged HD, it had something to do with volume headers..
I basically want to access my macbook's files and documents so that i can transfer them onto an external hd or back them up.. i just want my files afterwards i can reformat or whatever as long as i get the files and contents of my hd back..
Ive read of diskwarrior? Can i burn that on a dvd and insert it into my mac, then start my mac and then it allows me to drag and drop all the contents of my hd onto an external hd?
I need a genius to help me!! A step by step guide would really mean the world to me!!
Thanks in advance mysterious genius!!!

Step 4(a) open Disk Utility from Utilities on the menu bar, then proceed to highlight the external drive in the left sidebar as you say and choosing Partition from the row of buttons that appear top center in the main window of DU.
5(a) click Restore on the bar of buttons top center of the main DU window, then what you say. But use the name you have given the external drive in step 4, Mac OS X Extended (Journaled) is the way it has been formatted, use a name such as Backup or something obvious to you.
Step 7, On the menu bar, click File, then New Finder Window. In the left sidebar you will see Devices and the internal and external drives will be listed. Click the name of the external drive and then in the main part of the window you should see the contents of the external drive. You can click on the folder for Users, then your user name, and see what folders appear...make sure the folders such as Documents, Pictures and whatever else you use appear and have the content you expect to be there.
You want to be sure all the content has been copied over since the step of erasing the internal drive is going to permanently remove it from that drive.
And then after step 8, add step 9, from Utilities on the menu bar, choose Install Mac OS X, and if it asks where to install, choose the internal, Macintosh HD, as where to install.

Macbook w/ whole slew of problems...Won't Start Up, Disk Utility Can't Repair Disk, Horizontal Lines on Screen, Etc.

I purchased my Macbook in the summer of 2011 and before it went berserk it was running Mavericks. 3 years later, it's finally seemed to have run its course.
It won't start up normally and it won't start up on safe boot. Attempting to use disk utility to repair the disk only gives me the message: "Disk utility can't repair this disk. Back up as many of your files as possible." There are also horizontal lines across the start screen (before it inevitably shuts down) and the screen looks very faintly purple-ish/off-colored.
This actually didn't come out of the blue. On Monday, my macbook suddenly froze, went white, and beeped three beeps repeatedly. I restarted it and backed up all my important work files and set up an appointment at the genius bar for Friday once work ended. It remained buggy during this process with the beeps returning an occasionally a blue screen popping up.
Unfortunately, there wasn't enough space to back up my important photos and by the time I returned on the next day with an external hard drive to store them on, my macbook would no longer turn on.
Is there anything I can do to bring my macbook back to life? Ideally I'd like for it to last one more year before I graduate college. Is it still salvageable, and if so, is it worth salvaging?

I hate to spread gloom, but that computer has serious problems. The only people who can diagnose the problem(s) are technicians. I would take it back to the Apple store for further testing.
