'volume check failed', and disk utility can't fix it

I was planning to create a new bootable backup today and ran 'repair disk' from an install disk before cloning.
Unfortunately I grabbed a Panther disk by mistake, and only discovered it was the wrong disk as I took it out. By then, DU had run through the 'repair' - changing quite a few things - until it showed 'volume cannot be repaired'.
I've tried to correct them using DU from the Tiger install disk, but without any luck. DU shows:
+Invalid catalogue record type+
+Volume check failed+
+Error: the underlying task reported failure on exit+
+1 Volume could not be repaired because of an error+
My iBook still appears to be running perfectly, but obviously I need to repair the disk before I can clone it. Disk Utility can't do it - could DiskWarrior?
I'd really appreciate some advice on the options open to me, and the best way to do it.

Success!
I powered down and ran DiskWarrior a 2nd time to rebuild the directory. This time I skipped the recommended Preview stage and went straight to confirming Rebuild. Everything now seems to be fine again. DU finds no faults with the disk, and the iBook feels significantly quicker and snappier.
Two things I learnt that might be helpful - the first is, it's easy to be careless for just a moment and end up in a time-consuming mess. It's the first time I've done it, and I won't be doing it again.
Second thing is, when people say DiskWarrior is slow to boot, they mean it - it took at least 10 minutes to show up on screen, which is unsettling. And the Preview stage, for me, was equally unnerving.
Still, it worked - superbly - all my data is intact, the iBook is overhauled and working faster than ever.

  • Help! PB G4 won't boot and Disk Utility can't fix it!

    I have an insufficiently backed up PowerBook G4 1.67MHz (1GB RAM) that suddenly nosedived last night. I was surfing the Web and OmniWeb froze up. I couldn't force-quit it because the Finder was also locked up. So I held the power button until it shut down. When I restarted it, it got to the grey apple screen and hung there. I booted off the Tiger CD and ran Disk Utility, but it couldn't fix it. Then I tried booting into single-user mode and it also failed. Finally I tried reinstalling the system, but the CD couldn't find the hard drive. Aaargh!
    I have a bunch of documents that I really cannot lose, and the most updated versions of them are only on this drive. Anyone know any tricks or third-party utilities that can help? I have another Mac; would Firewire Target Mode or Network booting help?
    Some details:
    Here's what Disk Utility said:
    Invalid volume header (this was written in red)
    Checking Catalog file
    Keys out of order (in red)
    Rebuilding Catalog B-tree (in green)
    The volume [name] could not be repaired (in red)
    Error: The underlying task reported failure on exit (in bold red)
    1 HFS volume checked
    1 volume could not be repaired because of an error (in bold red)
    Repair attempted on one volume (in bold)
    1 volume could not be repaired (in bold red)
    Then it popped up a dialog box:
    First Aid Failed
    Disk Utility stopped repairing [name] because the following error was encountered:
    The underlying task reported failure on exit (in bold)
    Here's what single-user said:
    It all booted normally, then I got these ominous entries in the list:
    disk0s3: I/O error.
    jnl: dojnlio: strategy err 0x5
    jnl: open: could not read 512 bytes for the journal header.
    hfs: late jnl init: failed to open/create the journal (retval 8).
    nfs_boot: networking is not initialized
    panic(cpu 0 caller 0x001F2634): nfsbootinit failed with 6
    [then there's two backtraces here]
    panic: We are hanging here...
    PowerBook G4   Mac OS X (10.4.8)  

    As Mr Peck advised, DW is your best chance of getting out of this.
    The important point of your post is the hard shut down (were you running Classic?) and the mention of Keys Out of Order. Do a search on these boards for Keys Out of Order for a quick education of the problem.
    Make sure of the version of DW you use, get the disk and don't download, and make sure of your firmware version.

  • Disk utility can't fix my disk!

    I have a MacBook Pro 15" with OS X Mavericks. Latley programs have crashed for no reason, so i checked disk utilities, it found a problem, I turned off my computer, held down cmd + R, and disk utilities can't fix it there either. So I know I have to delete my disk, install OS X again, and all that... I know how to do this, but I don't want to loose all my files and programs (yes, not all of them are downloaded from appstore...). But since it's my startup disk that is broken, I can't start it normally, to take a Time Machine back up.
    Is there another way to take a backup without start up normally? Are there some codes in terminal I can use?
    Thanks for all answers.

    I tried CCC, and this happened... I had it on "Administrators" because I didn't want everyone to log on my comuter..
    But since my startup disk is broken, I can't start it and log on and fix it. Is there another way to turn it off?
    I used my hostname to remote clone it, would the IP adress have been better?

  • Hard drive clicking and disk utility can't repair

    I have an iBook G3 that recently started making a clicking noise from the left side of the computer. At the same time it froze up and now it won't start up. I tried to start it in safe mode and it didn't work. I was able to start the OS X install disc and start the disc utility, but I get an error: Invalid Sibling Link, Volume Check Failed.
    Does anyone know if there is anything else I can do to try to repair the hard drive myself? If not, how do I find someone reputable to get the data off of the drive (no I didn't back it up... ever) and install a new drive?
    Thanks for any suggestions!

    Hi, and welcome to Apple Discussions.
    You could buy DiskWarrior and see if it can repair your hard drive. It can often repair a hard drive when Apple's own Disk Utility cannot. No guarantees that it can do it for yours, but DiskWarrior has saved my hard drive several times.
    If you are able to get it up and running, be sure to back things up right away.

  • DiskWarrior and Disk Utility can't repair volume after 10.4.6 upgrade

    I appreciate any advice on the following problem:
    After installing the 10.4.6 update On April 4 (which installed just fine), I did my usual post-installation system maintenance including repairing permissions, running CRON scripts and cleaning the caches. I got a strange Apple Script error that flashed on and off the screen (too quickly for me to document) while I was cleaning the caches, then the process finished. Then when I used DiskWarrior as part of my usual maintenance, it "stuck" while saying that the process was slowed because of a disk error. I waited for an hour, and it never completed. I then restarted using the OS install disk, called up Disk Utility and selected Repair Disk. This is what I got:
    Verifying volume "Macintosh HD"
    Checking HFS Plus volume
    Checking Extreme Overflow file
    Checking Catalog file
    Invalid node structure (in red font)
    The volume Macintosh HD needs to be repaired (in red font)
    Error: The underlying task reported failure on exit (in bold red font)
    1 HFS volume checked
    Volume needs repair (in bold red font)
    I cannot repair this problem using either DiskWarrior or the OS installer disk with Disk Utility. In addition, I was unable to archive & install the system while using the OS install disk! I have tried repairing permissions and using DiskWarrior and the OS Installer disk again with no success.
    I am able to work on my Mac, but things seem slower and I get occasional oddball errors that make no sense. A few times, applications have quit unexpectedly when they weren't before.
    Am I going to have to initialize the hard drive and reload everything?
    Many thanks!

    Mac G5 (dual 2GHz)   Mac OS X (10.4.6)  

    I had a similar experience after installing 10.4.6.
    The messages I got in Disk Repair were:
    Checking Catalog file.
    Illegal name (in red)
    Illegal name (in red)
    Keys out of order (in red)
    The volume Rich's HD could not be repaired. (red)
    Error: the underlying task reported failure on exit. (In red)
    After a long time on the phone with Apple, we decided to reinitialize the hard drive. I have reinstalled the OS and am in the laborious process of restoring my user files and non-Apple applications. What a hassle! And I am not even sure all will be restored to proper functionality.
    Don't know if either yours or my disk failure are related to 10.4.6 but Apple better watch closely for user feedback. These are potentially disastrous problems for users if they have not backed up.

    Because it can not repair the errors I have started "repair disk". It says "can not unmount Macintosh HD". Even if I have started from the external disk?
    So I get my install CD (Mac OS X 10.5) and started from that. I got the same errors with that disk utility.
    Can someone tell me, if this are "right" errors or do I have to try more to repair this errors? My computer is running fine.
    I am a bit irritated now.

    Way back in Jaguar Disk Utility would pop up dozens of "advisory" messages of no interest nor meaning to anyone except possibly some programmers. This needlessly alarmed regular users. The same thing is happening again in Leopard. The SUID messages are not meaningful nor are they errors, in effect they are announcements that some list being consulted by the utility says one thing, the actual files say something else, Disk Utility is going to assume there is a reason for actual setting and not going to change it, but you (it's kind of assuming you are the programmer) should know this. If the "Die Zugriffssteuerungsliste" is German for ACL (Access Control List) it is the same deal: an ACL was found, but no one told Disk Utility there was suppose to be one.
    If the messages bother you download the whole 110MB 10.5.1 update and run it. It quiets down the output for all the SUID statements save one. Might even shut down the ACL advisories--don't know because I haven't bothered to download 110MBs of updater, I just ran the patch update.

  • Grey folder with question mark and Disk Utility can't find HDD.

    I have a 2010 MacBook Pro and for some reason the OS X does not boot up. Therefore I see the grey folder flashing. I tried booting into Recovery from holding options button but there are no available startup disks. So I installed Apple recovery on my USB and I boot up with that. I opened disk utility but it does not seem to find the hard disk. I also tried reinstalling Mac OS X and it gives me an error. Is there another bootable software except for Disk Utility that can check the HDD and see if there are any errors or is the HDD just dead?

  • Iphoto won't start - disk utility can't fix file volume

    I've posted my iphoto problems on the iphoto forum and they suggested I post here on the Tiger forum.
    It all started when I completed the automatic software upgrade for iphoto and other applications (can't remember which) and when I started iphoto, all my pictures disapeared in front of my eyes. Tried a number of tricks suggested on the iphoto forum and one worked for a while but now iphoto won't even start up.
    One suggestion was to fix disk permissions. This did not work and got a message that there was on error in one of the file volumes. When trying to fix that using disk utility, the application can't exit properly and the problem persists. Another suggestion was to use DU from the start up disk and I did that with no results, same problem as before.
    HELP! I can't use iphoto and it appears I have something wrong with my hard drive. All other applications appear to work fine and I have all my photos and music backed up on a backup drive.
    Do I need to re-install Tiger? Help Please
    Intrepid 007

    If you have run Disk Utility and it cannot repair the drive then you have a couple of choices. First, you could purchase a more robust utility such as Disk Warrior or Tech Tool Pro or Drive Genius. Disk Warrior is an excellent program for repairing the disk directory.
    You could do a reinstall, just make sure to backup all of your files first. If it were me I would do a reformat and reinstall rather than an archive and install just to insure that whatever corruption is on your system is gone, but that is me.

    Permissions repair complete
    Is this OK? If so, why it does show this? If it's not OK, why it can't fix this problem?
    And it takes 4-5 longer to run "Repair Disk Permissions" than it was on OS X Tiger.
    I sent this report also to the Apple Mac OS X Feedback. Just wanted to know is this Disk Utility report normal?

    But this repairing process takes about 4-5 minutes, while on Tiger it took about 1 minute.
    That is normal in Mac OS X 10.5.

  • Disk Utility can't fix error...

    Hi people...
    I have a G4 iBook, 933mhz, 640ram, 80g HD. It's on OS 10.4.11. Everything has been running fine, no problems for a long while, until this morning.
    I turned the computer on, and it loaded/booted fine up to the 'Login' screen. I popped my password in, pressed Enter. Usually, with in a matter of milliseconds, my current wallpaper appears, followed by the menu bar and the HD icons etc. However, today, after entering the password, the login box disappeared and left the Aqua default wallpaper in the backround. I left it for about 5 minutes and it just stayed as it was, so i powered down. I put in my install DVD and booted up Disk Utility. I got the permissions checked and verified, all were fine. I then done the disk verification. Within a matter of minutes, it came up with an error in bold red (apologies in advance, i didn't record the code). I tried both the repair and varify options and neither could solve the problem.
    I restarted the computer and it loaded fine, until i'd put my password in again. So this time i left it for about 15 minutes. When i returned, it had managed to load my current wallpaper, but nothing else.
    Does this sound like a serious problem? I don't want to re-install as i'll lose lots of information on the computer. Has anybody else experienced similar? Could i re-install if there's a HD error?
    Any advice welcomed!
    (if i remember correctly, the error on screen was something like: "HD error, 90, unable to complete process" or similar).

    Hi guys
    Well, last night, i ran Disk Utility, an the error was that bad that it still couldn't fix it. I started the computer up as normal, and after login, i left it for nearly 2 hours. Desktop eventually loaded up, and once loaded, the whole computer behaved as normal. I backed-up my files/pics etc (not alot thankfully as i'm a regular back-upper (you learn after losing a hard-drive with major projects on!)).
    I then ran DU in situe, and it reported the same error-"Error -9445. Keychain length not long enough: 0 volumes repaired". As i had backed up the info, i restarted it and tried again. This time it booted up as normal. So i ran DU again, but it still reported the same error. Everytime i tried to 'Repair' on first aid, the option was ghosted-so upon selecting Verify, it started to check, telling me it needed to be repaired, then Repair wasn't a option. Unfortunately i was without Internet access last night, so was unable to accesss this information, and i can't tell you what the S.M.A.R.T. status was.
    I figured that as i had backed up the info i needed, i'd start up with Install the disk, try erasing the HD, and then run First Aid Repair Disk, knowing full well that i would be 'Zeroing' the HD and reinstalling in the next few days. So. i bravely erased the HD.... i ran the Repair Disk....the result? Tune in tomorrow folks!
    No, just kidding-the result was fine. No errors reported, volume 'Dan's G4 was successfully repaired' (in green type, something i had begun to miss!). So i now know that i'll need to install the OS again, but at this moment in time it appears the the HD is ok. Obviously i won't know until the system is re-installed, but i do have access to a PC with internet connection at the moment, so if it all goes pair shaped then i can report back. However, when i'm all up and running, i need to learn about partitioning, so i'll be back to report regardless...
    The only further question i have is concerning re-installation. My iBook came with OS 10.3.4 over 3 CD's, plus the 4 software CD's. I upgraded and bought OS 10.4.7 on DVD. So what do i use for installation? Do i use the original 10.3 CD's, or do i use the 10.4 DVD? I'm not sure if the CD's contain vital info that the DVD doesn't? Sounds a silly question i suppose, but i don't want to spend 2+ hours installing, then another 2 upgrading when i put in 10.4!
    Cheers for your help, and thanks in advance for your info!

  • Stuck at "starting login window" and Disk Utility won't fix it...

    I downloaded some security updates, and since restarting my computer as required, I have never been able to start it up since. It gets stuck on the "starting login window" screen, with the little blue bar still shimmering and mouse still moving, but just won't ever load the login screen, even after hours.
    I've seen a few other people have had this problem, and tried to follow some of the recommendations, with no joy. I tried several times to repair the disk permissions with Disk Utility, but it has an internal error saying it lost the connection to the disk manager, or something similar.... when I try to repair the disk, it fails saying something about "overlapped extent allocations" and an "invalid node structure".
    I can start up in single-user mode, and doing a fsck had the same result.
    What can I do??? Some people suggested an Archive and Install manoeuvre, but I'm scared of losing all my files! Will it erase them all? Do I have to back up all my files before doing this? How can I back them up if my computer won't start?
    I know almost nothing about computers - all I know I have found in the past few days searching through these discussion boards trying to find an answer! I have an important essay due on Monday which is stuck in my computer, so I'm a little scared!
    I'm using Mac OS X Panther or something.... not sure how to find out exactly which one, as my computer won't start!
    Any help would be greatly appreciated!
    iBook G4    

    Hi, you have some serious directory damage there, and it was probably there before the updates. An Archive and Install would not be recommended. If you did that you would likely have more problems then you have right now.
    If it were me I'd run Diskwarrior and Tech Tool Pro on it. DW for the invalid node structure and Tech Tool Pro for the Overlapped Extent Allocation. But you probably would have to buy both of them, and there's no guarantee either one will fix it.
    Apple doc.#25770, talking about Overlap..... says the easiest way to fix it is to Erase and Install. If you are running 10.3.9 and had access to a retail Tiger disk, you could try booting up on it and running Disk Utility. Tigers DU has the ability to fix Overlap.... sometimes, Panther's does'nt.
    This is the best way to Erase and Install. First backup all your important stuff, if you can, as the following will erase everything on your drive; it will be unrecoverable. Put your install disk in your Mac and Restart while holding down the C key. In Tiger, When you get to the install screen, don't click install and go to the title bar at the top of the screen and click on Utilities (in earlier OS's click on the installer menu).
    Click on Disk Utility and choose the hard drive you want your OS on. Then click on the Erase tab. In Tiger, click on the Security Options button near the bottom (it's similiar for Panther and Jaguar).
    Once in there choose Zero Out Data (write zero's in earlier versions). This will map out any bad blocks on your drive and bring it back to almost new condition (providing there's nothing wrong mechanically with it, bad bearings, defective or damaged surface, etc.).
    Once this is done, go back to the install screen and begin the "Erase and Install" installation. This will put a factory fresh system on a clean hard drive.
    Cheers!

  • RAID drive is listed as "failed" in disk utility - how to fix it ?

    hello all. I set up a RAID with two LaCie 250GB drives about two months ago and have been using it to handle my itunes library and some back up files. It was working fine but launched disk utility the other day i looked at the mirrored raid and it said it was "degraded" and that one of the drives has failed. The first question is how do i fix the situation - do i need to "rebuild" the drive through disk utility ? and if so will i loose info or since it is mirrored, the other drive will simply overwrite it with the redundant information ? I was just intimidated by the warning after clicking the rebuild button...that my drive will be wiped. I have looked and some suggest I restart, plug unplug the firewire, etc and i have doen all of that.
    Any help would be great.
    thanks

    Two things. First for the permissions check, reinstall the 10.5.2 COMBO update and repair permissions. That should fix things. Alternatively, search these forums for ACL, sort by date, and read the responses and the article Apple posted three months ago: http://docs.info.apple.com/article.html?artnum=306925
    Second, for the *Incorrect number of file hard links* error, follow smithrj's advice. If DU can't repair the disk, you'll need something stronger, such as DiskWarrior.
    BTW, please update your *My Settings* profile info. It still shows that you're running Tiger.

  • Disk utility can't repair disk, back up and restore files......I need help, I'm worried I'll lose all my photos, files etc

    Mac started hanging up while streamlining a kids show. Restarted and got the screen with the apple and the circle. restarted with control-option p and r. Ran disk repairitem got the following results;
    invalid index key,
    it rebuilds catalog b-tree,
    volume repair complete,
    updating boot support partitions for the volume as required,
    Error disk utility can't repair disk
    I'm then prompted to back up all files, reformat the disk and restore backed up files.
    Obviously need help here as I think I'm in danger of losing my files, photos etc if I don't do this right.
    Can anyone help
    Steve

    You might want to back up the disk as soon as possible, do the repair, then back it up again. First time will have the issues that Disk Utility can't fix, however, you'll have the data saved.  Then, once you get things repaired, make a new backup, and go from there.
    If you're going to use a hard drive directly connected to your iMac for backup, this is what I mentioned earlier: http://twelvesouth.com/products/backpack/ Great way to use space behind the iMac without adding something else to the desk top. You can buy it through Apple online/stores or Amazon, and there are probably other sources too.
    For external hard drives, I like those sold by OWC at http://eshop.macsales.com/shop/firewire/ as many of them use Oxford chip sets, wihch work well with macs (I've used several for years with no issues). Most pre-packaged drive/cases have a 3 year warranty, although you can buy a case and add your own hard drive. I like Western Digital Scorpio Blacks that have a 5 year warranty.
