Repair Disk is not successful

While going through a verify/repair disk with OSX open, it said I needed minor repairs.
I booted the OSX installation disk and ran verify/repair disk on my HD and drive. Both times the error said "1 HFS Volume Checked; 1 volume could not be repaired because of an error."
I then restarted to sign back on and now nor my administrator and guest password will not work.
I booted the OSX installation disk again to reset the password from there. It said it was successful.
I then restarted to sign back in and the passwords still do not work.
What should I do? If I reinstall the OSX all together should this fix the problem (I have everything backed up)? If so, is there ANY way I can access some files before doing so to make sure my backup is the latest (basically, sign back in before deciding to do so). Thank you in advance for your help!

Hi Matt, and a warm welcome to the forums!
Unfortunately, Disk Utility can't fix all that much, and the only other Apple Options are erasing the HD, or installing OSX to a second drive, then using Migration Assistant to move stuff over to the new HD.
You must repair the HD, if Disk Utility or fsck should fail to repair it, your best bet is DiskWarrior from Alsoft, you'll need the CD to boot from...

There are other ways if you can't get DiskWarrior, let us know.

Repairing Disk Permissions - Not Working with Lion

I simply am not able to repair disk permissions when my Mac is booted normally - the disk utility hangs and never stops - when I boot in recovery more I can run the utility just fine - and then boot as normal. I am wondering what might be causing this or if anyone else is having a similar problem?

With Lion, it is best to do any disk repairs via the recovery partition
And why do you say that? I have heard no such thing, and this was never the case with previous systems. It has always been recommended to repair permissions while booted from the system whose permissions need to be repaired. Do you have documentation that this recommendation has changed?
Joe, repairing permissions works fine for me without needing to boot into recovery mode. Are you giving it plenty of time to finish? Sometimes it may seem to be frozen... sticking on "less than a minute" for well more than a minute, for example. Have you repaired the hard drive (which you do need to boot from the recovery partition to do)?

Repair Disk Permissions not working?

Based on a printer problem, HP suggested that I run Repair Disk Permissions. I did, generating 9 pages of fixes. But if I clear the history and run it again immediately, the same list of repairs is generated, suggesting that nothing was fixed.

It's no problem, see this

HT1199 I upgraded my iTunes player on windows 7 and the upgrade did not complete successfully. Attempts to open itunes gives an error that msvcr80.dll is not installed. Attempte to run the upgrade againa and repair iTunes was not successful.

How to install msvcr80.dll after attempted upgrade to iTunes version 11.1.4 on Windows 7?

This worked for me
Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall press on)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

Windows 7 repair disk does not work

I have a Lenovo T430 laptop (2342CTO). When I wiped my hard drive (after a Windows 7 boot failure), I installed Ubuntu 13.04 instead.
Now, I want to reset my PC back to Windows, and I have the factory reset disks (3 disks). I tried booting into them but it won't work. I can't reset my PC anymore.
My PC had Windows 7 Home Premium 64-bit preinstalled onto it when it was shipped to us. Probably because I have Ubuntu now, there is no recovery partition anymore, and so it cannot reset.
Please help find a way to get my old Windows back. Thank you.

HELP! while upgrading from 10.6.8 to mountain lion on MacBook pro encountered Mac HD error. Verify indicates Repair Disk needs to run but it will not highlight. Verify Permissions indicates I do not have access. Reinstall does not work. Tx. Freaking out

Really nervous. Can't get any of the support instructions to work. Error occurred while installing mountain lion upgrade from 10.6.8. PLEASE HELP!
I know I'll be checking for responses all night. Thanks

Assuming Mountain Lion did not install, you'll need to boot up from your Snow Leopard DVD (by holding down the C key while you reboot).
Once you've booted from the DVD (be patient, it's not exactly lightning fast!), you'll want to go to Utilities --> Disk Utility...and run Repair Disk.
The problem you're seeing is that there's something not right with your MacBook Pro's hard drive, and Repair Disk cannot be run on the same volume you booted from.
If Repair Disk was run successfully when you booted from the Snow Leopard DVD, and you see indications that whatever was wrong was corrected, you can now boot back up again from the MacBook Pro's hard drive. Once you're up and running on the internal hard drive, try installing Mountain Lion again.

Wait... your not talking about trying to repair the Mac OS X Install DVD are you?

Rationale for Repairing Disk Permissions

I repair permissions before and after installations, and I suggest others to do so. However, I have read in some threads in Discussions there there is no technical basis for repairing disk permissions before installation, and that only repairing after installation is necessary.
I realize that there are different opinions about this, but beyond opinions is there a technical basis or rationale for repairing disk permissions before installations?
Thanks.

Hi cornelius,
Here is some reading about this topic. Mind that Apple DOES recommend repairing permissions as routine maintenance (see links at the bottom)! My suggestion to Repair permissions before and after an update has a very simple rational: If you forgot to repair permissions AFTER the last update you might get into trouble. Therefore it is safe and costs only a few seconds to do it before and after the update.
mac.column.ted: Unravelling the Repair Disk Permissions controversy
"Ted Landau
May 2006
Repairing Disk Permissions. Not exactly a topic that you would expect to spark much controversy. Yet, surprisingly, it is the focal point of a rather heated debate.
The command itself is innocuous enough. It is included as part of the First Aid component of Disk Utility. Apple's Help for Disk Utility states: "User permissions associated with files, folders, or applications can become damaged and prevent a file or application from opening. Permissions problems can also cause your computer to run slowly. Using Disk Utility, you may be able to fix these permissions problems...Repairing permissions may also be recommended after updating the system or installing new software."
Consistent with this, many users and Web sites (including MacFixIt and at least some postings on MacinTouch) recommend the use of Repair Disk Permissions, not only for specific signs of trouble, but as a part of generic troubleshooting and ongoing maintenance for your Mac.
In contrast, other members of the Mac community (writing in locations such as the Daring Fireball , Unsanity, and the MDJ) argue that running this command just for maintenance, in the absence of any particular symptom, is essentially worthless. Some critics go even further and claim there is no justification for ever selecting to repair permissions. Not only is it useless, they contend, but it may even cause new problems to appear. This viewpoint is often expressed with inflammatory rhetoric such as "covering yourself in Vaseline and rolling around naked in the dirt and repairing permissions are just as likely to fix your Mac OS X problem" (Unsanity).
Regardless of who's right or wrong, I don't believe that insulting users is merited here, especially when these users are simply following advice suggested by Apple itself. As it turns out, I also do not agree with the position of these critics. So, although I may be stepping into a minefield, here's my own take on this subject and my resulting recommendations. [Disclaimer: I was not involved in the authorship of previous MacFixIt articles on this subject. This column is my separate opinion, and does not necessarily reflect the views of MacFixIt.]: Continued"

Worried about need to constantly repair disk permissions

Here is my analysis and conclusions as to why I need to constantly repair disk permissions:
I recently got the top-o'-the-line iMac (see info below) which shipped with Lion but since I wanted Snow Leopard (just because I have a few PowerPC games that I can't live without) I reformatted the hard drive - into 1 partition from the 2 that Lion had - and installed Snow Leopard and went back to business as usual....only with one **** great and fast computer. BTW, as far as I know this computer is exactly the same computer that shipped with Snow Leopard prior to Lion's introduction. I swore that I would never get another desktop computer because this one would last me forever. My only hesitation now is because the need to constantly repair permissions means something is not right. On the one hand I could just keep on repairing (daily?) the permissions for the next 20 years, or.... what? Is it possible (or should I be asking Apple itself instead of in this forum) that there is some other difference between the Snow Leopard and the Lion versions of this iMac - is this what "firmware" is all about? - that produces this constant need to repair permissions? If that's the case, would Apple give me a Snow Leopard-friendly logic board (and/or install the correct firmware) in exchange for the Lion logic board - or am I just going to have to live with having to perform this permissions-update function? Or is having to repair disk permissions not a big deal or something worrying about? Any ideas would be appreciated - thanks!

Error when REPAIRING DISK

"INVALID LEAF RECORD COUNT"
And repair disk does not seem to fix this. Any ideas what this mean and should I be worried?
Thanks

Yup and in fact it's entirely possible NDD made it worse than helped. That's one of the worst pieces of software for OSX every to hit the market, I've never seen anything so incompetent and useless.
That said, What I think you ought to do before running any further repairs, is at the very least copy your data files onto another drive or a DVD or what ever. Backup what you have regardless of what you think may or may not be corrupted. The last thing you need is any of these tools fixing the drive and ending up with unreadable sectors where your files sit, then you're looking pretty stuck.
Forget cloning and all that, just drag and drop files onto a CD-RW and burn them. You can figure out later which ones are busted, and if you drive does get fixed, then you can toss those.
At this point, I think you have an issue with the drive itself, I think it's more than just corrupted files. So I would seriously consider a replacement drive too. I have only seen a drive not fixable by Disk Utility or DW once, and after formatting it, I could not even install the software on it because of errors the drive was totally kaput.
How old is your drive/machine anyway? Over 3 years?

I tried installing Yosemite from 10.6.8 and the install failed. Ran a check and disk needs repai but "repair disk" isn't an option (greyed out). Can't start up under old 10.6.8 because it says "could not gather enough information." Help, please!

startup disk fail

Not lame at all. It's annoying that in order to salvage a disk the "official" way is reformat it. It's just a lack of documentation.
Diskwarrior is actually a software from Alsoft. www.alsoft.com
It's been around for ages and usually it's the last resort when everything else failes.
If you don't have the software, you could try one option.
Restart the malfunctioning computer and press T when you hear the startup sound. This will start the computer in transfer mode. You will see a huge firewire icon on the screen that just floats there.
Connect the computer to a healthy mac with a firewire cable and it should appear as a HD, just as an external hard drive would. (don't worry if it doesn´t)
Open Disk utility and in the left pane the malfunctioned Hard drive should appear. Run disk repair on the HD if possible. Once the repair disk has finished, with our without errors, open a new finder window and select the external hard drive.
You could backup the data on the Drive at this stage onto the healthy computer... just to be safe.
On the root of the Malfunctioned Disk there should be a folder named "OS X install data" or something like that. Basically something that normally would not be there...
Delete that folder.
Run Disk repair once again in Disk Utility. If successful, reboot the machine and see what happens.
If that does not work at all, then perhaps you should consider purchasing Disk Warrior. Run the same process as before, connecting the malfunctioning mac via firefire, but this time run Diskwarrior on the healthy machine, locate the malfunctioning HD and select Rebuild for that Hard drive. It will take a little while but once its done processing it will ask you if you want to copy the new build, select yes. That did it for me at least.
I hope that helps. You could check the app store or search online for software that is similar to Diskwarrior, there's probably some app that does the same thing. The only reason I used Diskwarrior is it has proven a good utility for Mac breakdowns and I've used (rarely though) it for years.

Disk Permission Repair failure after partially successful update

The 10.5.2 update of my PowerBook G4 stalled at 'Writing Package Receipt'. After a hard reboot, I was able to access the desktop. The About This Mac showed 10.5.2 but there were no appropriate confirmation files in Receipts/boms or in the Console Log.
Attempting to complete the update using the Combo Package was not successful.
Tried to repair disk permissions from Disk Utility: never completed. So tried to repair permission using Disk Utility in the Leopard Installation DVD. This showed and warned that many of the permissions were changed and none of the permissions were corrected.
I have no clue what to do at this point other than an archive and install. Any suggestions from the wise folk who frequent this discussion board?

I finally resorted to an 'Archive and Install' option from the Leopard Installation DVD followed by Software Update. It installed 7 items including 10.5.2 Combo update. This was followed by the Graphics Update. I checked Installed Updates, Console and Library/Receipts/boms. All show that 10.5.2 was installed. I had a few anxious moments while the computer kept rebooting during the update process, but I kept my fingers away from the keyboard or power button! The update process did not take that long either.
Everything looks good to go-I will keep you folks informed if OS behavior is unusual.
Thanks everyone for your suggestions.

Can not update my system and not able to repair disk

I havn't used my macbook pro for about a year, and recently I need to travel to another place and need it with me.
I see in AppStore that there is an update for my ios, I downloaded it, and run the install.
however, when updating my system. I run into some error, the installer says the update installation failed, and I should restart the computer and repair the disk before continue.
I tried to restart in safeboot, not working, the screen stucks at the apple logo for over half an hour.
And tried to restart with my harddrive, the system tells me I can not select that disk to restart.
I an able to run disk utility from the installer. I can verify disk permissions .
But when I run the disk verify, it gives me an error:
Verifying volume "Macintosh HD"
Checking file system
Performing live verification
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
The volume Machitosh HD could not be verified completely.
Error: This disk needs to be repaired. Click repair Disk.
But the "Repair Disk" button (and the repair permission button)is gray and can not be pressed, when put my mouse over the "repair disk" button, a line of text shows up:
"repair the structure of the disk's file system, if necessary
Not available becaue the selected disk can't be written to."
the repair permission gives me "Not available becaue the selected disk can't be written to." as well.
What do I do now?

QiaQiaC,
which model MacBook Pro do you have, and which version of OS X is installed on it?

DisK Utility Not Repairing Permissions

Hello, I have a problem with my iMac.
The problem is as following: I cannot repair permission using Disk Utility.
What happened first was that I wanted to install a program from a mounted drive, however a Pop up occurred and said the framework of installer was incorrect.
After that, I went to Disk Utility and clicked repair permissions when a Pop up like this came up:
http://img219.imageshack.us/img219/2582/picture1mt4.png
What is the problem?
Thank you for any help,
Daniel

-are you running Disk Utility from the HD or booted to the instal disk?
-what are the affected files?
If the file(s) was not installed by the mac OS X installer, Repair Permissions will not fix the issue
Tip:
If the files are located in your home folder,
boot to instal disk#1,
choose Reset Password Utility from the menu bar
and "Reset Home Directory Permissions and ACLs".

Gray screen on start up and not able to repair hard disk and not able to take back up.

My macbook pro bought in early 2011 with snowleopard software and than upgraded to lion is now running on system 10.7.5 .
My problem is i get a gray screen on startup with apple logo and spinning ball.
I tried all the solutions mentioned in the apple support for "gray screen appears during start up". This Disk utility says that the Hard disk cant be repaired.
Before i format my disk and erase all data and install Mac os x again, i want to take back up on a external hard disk. I bought a new 2tb external hard disk so that i can take a back up.
As i try to take the backup of the image, it gives me an error "cannot allocate memory"
i tried to change the configuration from compressed to read/write and tried different encrption methods but unable to take backup.
i sometimes get error "input/output".
how do i take a backup. somebody please help

See OS X- Gray progress bar appears under Apple logo during startup. If you need to reinstall OS X, then do this:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. 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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.
