Disc Utility says it fixed the invalid extent entry but it lied!

Hi guys and gals
Just wondering if anyone else came up with this problem:
My powermac G4 running OS 10.2 only starts up to a blue screen and nothing else. I ran Disc Utility first aid on it and it said it had an "invaild extent entry" which it fixed, but the problem is still there.
I ran Nortons Disc Doctor, which never completely finished but freezes about 3/4 of the way through. Can't run Speed Disc because the drive won't mount.
Ran to the Disc Warrior which did fix some bad directories, but then froze at the "Building Report" stage.
Again I may have to suck it up and erase and reformat the drive, but I didn't back up lately (I know I know bad girl) and again there are some important files that I need to get to.
Any help would be much appriciated!
Thanks in advance!

Hi htmlneophytea,
1. disk utility in 10.3.x cannot repair this error. This was only implimented in the Tiger version of disk utility.
2. Your problem has a name: Norton Disc Doctor! Norton Utilities and Disk Doctor were discontinued more than a year ago (for some very good reasons!). It caused much more trouble than it solved.
Here are the articles:
Symantec discontinues Mac Norton Utilities, SystemWorks
Norton Utilities, SystemWorks development halted

Tech Tool Pro and DiskWarrior are presently the most reliable utilities. For more information on regular housekeeping read this: MacOS X 10.3/10.4: System maintenance

  • Safari wont open; disc utility says errors on the drive but cant fix them

    Hi, Safari isnt opening despite my installing it again from the CD as well as trying to install it from the latest version available online (I saved it onto my thumbdrive from another computer). So I ran disc utility and it says there are errors but that its not allowed to fix them since its mac HD that has the errors.
    I couldnt copy and paste the log as it says 'not enough memory to complete the operation' but this is what the last bit said:
    Volume bitmap needs minor repair check volume information. The volume MacintoshHD needs to be repaired.
    Error: The underlying task reported failure on exit.
    Additionally a lot of other applications: tech tool deluxe (from the apple protection plan CD), word etc. have been quitting for no reason. Is this a virus? Is there anything I can download to fix this?
    Please help, I'm desperately trying to fnish my thesis on time...any suggestions would be hugely appreciated.
    Thanks in advance.

    Welcome to Apple Discussions
    I ran disc utility and it says there are errors but that its not allowed to fix them since its mac HD that has the errors.
    There are no viruses on your machine. Macs to date have not been affected by the typical viruses seen on PC's.
    It seems you have directory errors on your Hard Drive. These can be caused by the machine shutting off unexpectedly (power failure), corrupted application code, or even lack of routine system maintenance.
    You cannot correct directory errors on the same drive you are operating from - in this case your Hard Drive. In order to correct the errors, you need to start-up from your Installer DVD. Insert the disc. Once loaded, restart the computer. When the screen turns momentarily dark, hold down the C key. This tells the machine to start up from the DVD rather than the Hard Drive.
    You can release the C key once you hear the CD engaged and the grey Apple screen appears. When fully installed, go to the Installer Menu and select "Disk Utility". When the Disk Utility panel appears, single-click on your Hard Drive on the left side. This will open the First Aid Panel. On the right you'll see "repair disk". Select it. Errors will appear during the process. Once done, continue to rerun until you get a clean pass.
    Once finished, quit DU and quit the Installer. This will automatically restart the computer. From here, the log-in screen ought to appear and ultimately your Desktop.
    When complete, go to the Utilities folder and select "disk utility". Again, highlight your hard drive. In the first-aid panel on the left select "repair permissions." This will not take very long. Refrain from using the computer while it is running.
    Post back with results - there is more to do.

  • Error: The underlying task reported failure on exit / INVALID EXTENT ENTRY

    In trying to verify my HD, I get this error message:
    Verify and Repair disk “Macintosh HD”
    Checking HFS Plus volume.
    Checking Extents Overflow file.
    Checking Catalog file.
    Invalid extent entry
    Volume check failed.

    I've tried Disk Utility (not from startup volume) with no luck. I've also run DiskWarrior several times and still get the same message... What am I missing? How do you repair an INVALID EXTENT ENTRY? Is my HD about to bite the dust?
    Any help would be much appreciated!

    Welcome to Apple Discussions.
    I am surprised that Diskwarrior was not able to take care of this problem, but Handling "overlapped extent allocation" errors reported by Disk Utility or fsck may provide the ultimate solution for you.
    Make sure to use Disk Utility to check the S.M.A.R.T. status of your drive. If you get a good report the drive should be OK.
    This problem is a characteristic of a full Hard Drive. If that describes your Hard Drive, Freeing space on your Mac OS X startup disk, by Dr. Smoke may prove to be helpful.

  • Repair utility says to load the disk, but no disk is provided.

    The Lion comes as a downloard, no disk. But the repair utility says to insert the disk to to the repair.
    I asked tech support if that were true. She said it was not true. I asked them to change the instructions to reflect what one really needs to do to repair the computer if it fails, and she hung up on me. (Really, no profanity, no insults, just a plain question. Must be a rough week with the Lion intro)
    I still need to know if I need a disk available to repair the computer if it fails. Or how one would know how to repair it if it does fail without the disk and without the computer giving me instruction.
    There is no written manual to explain. I am guessing that the we are presumed to be omnicient.

    I've noticed that Lion creates a Recovery partition on your hard drive. Did the message say Repair or Recovery?

  • Invalid Extent Entry error

    I have an iBook 9.2.2 and am getting an error message "Problem: Invalid extent entry, 44165, 4075" when running Disk First Aid. It says Disk First Aid cannot repair this problem. Does anyone have any suggestions on how to repair this problem? THis is a laptop for special needs children.

    Welcome to Apple discussions!
    The directory on the Hard drive has been corrupted. The "index" of what files are where is out of whack, and there is no way to repair it that is completely risk-free. You will need to take one of two approaches:
    1) use an Industrial strength Disk- or File- Repair Utility. Popular ones include alsoft Disk Warrior and Tech Tools (now supplied by Apple when you have an Applecare contract). DO NOT INSTALL these programs until the damage is completely fixed -- Get the CD version and boot from the CD, do the Repair, check again with Disk First Aid, THEN they can be installed, if you wish.
    Norton Utilities for Mac has repeatedly failed Mac users by not keeping their software appropriately upgraded to match the Mac Operating System. Using the wrong version can wipe out your Hard Drive.
    If you are working within a School System, the school's Tech Support should have a plan and the necessary Utilities and know-how to address these sorts of problems. When you have a large number of computers to look after, these problems come up regularly in Macs and PCs.
    -OR-
    2) Back up the files you can still read and re-initialize the Hard drive.

  • Kernel Panic (Invalid extent entry)

    While trying to run CampTune to expand my Windows partition, I encountered an error. With each OS X reboot attempt, I get a Kernel Panic. Windows partition was not affected. I attempted to repair the disc using the install disc, but initially was getting "no valid packages,"message, but now it says "Invalid extent entry." Fortunately everything was backed up days ago in TM. I first tried an Archive and Install, but that failed. Now as I attempt to re-install Leopard, it's saying that the destination disc needs to be erased.
    Re: "no valid packages" "Invalid extent entry" messages; will a clean install fix the problem?

    You would need to use Disk Warrior to rebuild the directory in order to fix the error. Erasing the drive and reinstalling OS X should also fix the problem.
    "No valid packages" occurs if the /Library/Receipts/ folder or its contents is deleted or corrupted.
    Using third-party software to alter the Windows partition will result in the partition no longer being manageable by Boot Camp Assistant. This is not advisable because if you later decide to remove the Windows partition you will have to repartition and reformat the entire hard drive.

  • 'fsck -fy' yields "invalid extent entry, invalid node structure"

    Hello all,
    System seems unstable. Many different apps, including System Preferences, crash on launch.
    In Single-User mode (Command-S at boot), ran 'fsck -fy' (multiple times) and the receive the following errors that cannot be repaired:
    Invalid extent entry
    Invalid node structure
    Volume check failed
    What options do I have to fix this? No claims by Alsoft (or other disk-fixing utilities I know of) that DiskWarrior works on Intel-based Macs to resolve an issue such as this. Are there really no disk-fixing tools for Intel Macs?
    Is the only option to format and reinstall and if so do I have to "zero all data"? And if I have to zero all data, how long will it take?
    Thanks for any insight.
    Cheers,

    Thanks again, iVmichael.
    Thanks for your suggestion... So I did boot off of Install DVD and ran Disk Utility from there and here is what it reported:
    Checking HFS Plus volume
    Checking Extents Overflow file
    Checking Catalog file
    Invalid extent entry
    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
    I tried another suggestion I got from the EIMS-L list which was to use another Mac to repair the MBP in FireWire target disk mode. I did that and was able to run Disk Utility from my other Mac (1.33GHz PowerBook G4) but it reported same errors. On the other Mac I tried to run DiskWarrior 3.0.3 (latest) but it failed to "see" the MBP's disk even though it was mounted and Disk Utility saw it.
    So I will probably reformat and reinstall everything!
    Thanks for your suggestions...

  • What now? I got repair failed  "Keys out of order" and "Invalid extent entry"

    What now? I tried to verify & then repair disk and I got "repair failed"  "Keys out of order" and "Invalid extent entry"

    You've booted from your OS installer disk, ran Repair Disk from Disk Utility? If so then you need a stronger disk repair utility like DiskWarrier to rebuild the directory.
    BTW, update your profile information.

  • Missing Thread Record and Invalid Extent entry when booting

    Hi all,
    When I boot up my PowerBook G4 it freezes. When I boot into single user mode and run fsck -fy I get the following messages:
    ** /dev/rdisk0s3
    ** Root file system
    ** Checking HFS Plus volume
    ** Checking Extents Overflow file.
    ** Checking Catalog file.
    Missing thread record (id = 72)
    Invalid extent entry
    (4, 14531)
    ** Volume check failed.
    I do not have Disk Warrior nor the Apple disks with me. Any help you can provide is greatly appreciated. Navigating my disk in single user mode seems to have all my directories etc.
    Thanks!

    I am trying to back up my data now. I only have my FAT32 formated iPod with me and I'm trying to mount it to backup my photos before I reinstall. Unfortunately I do not see my iPod popping up in /dev at all so I cannot even mount it.
    It's a USB connection so I suspect that single user mode doesn't pick it up... Any advice on how to mount a filesystem from my iPod in single user mode is much appreciated.
    Thanks.

  • I purchased an ablum thru itunes on my phone and it says i purchased the songs on itunes but when i go on my music it says i have to repurchase all the songs how can i get the songs with out havin to pay again

    I purchased an ablum thru itunes on my phone and it says i purchased the songs on itunes but when i go on my music it says i have to repurchase all the songs how can i get the songs with out havin to pay again

    Whether you can redownload music depends upon what country that you in. If you are using your computer's iTunes then does music show in the Purchased link under Quicklinks on the right-hand side of the iTunes store home page (on your phone you might be able to redownload media via the Purchased tab in the iTunes store app) ? If music shows there, but not that album, then check to see if it's hidden : http://support.apple.com/kb/HT4919
    If you aren't in a country when you can redownload music and it's still on your phone then you should be able to copy it over from the phone via File > Devices > Transfer Purchases.

    i bought a second hand ipod 5 and the original owner forgot the email and password and i can't restore the ipod and it says i need the original apple ID but i dont know it could anyone help me??

    If you can access the device: Tap Settings -> General -> Reset -> Erase All Content and Settings.
    If you can't do that then you need to Restore it as New:
    Locked Out, Forgot Lock or Restrictions Passcode, or Need to Restore Your Device: Several Alternative Solutions
    1. iOS- Forgotten passcode or device disabled after entering wrong passcode
    2. iPhone, iPad, iPod touch: Wrong passcode results in red disabled screen
    3. Restoring iPod touch after forgotten passcode

    5. iOS- Understanding passcodes
    6. iTunes 10 for Mac- Update and restore software on iPod, iPhone, or iPad
    Forgotten Restrictions Passcode Help
    You will need to restore your device as New to remove a Restrictions passcode. Go through the normal process to restore your device, but when you see the options to restore as New or from a backup, be sure to choose New.
    Also, see iTunes- Restoring iOS software.
    You can also try using DFU mode:
    Placing your device into recovery (DFU) mode:
    Follow these steps to place your iOS device into recovery mode. If your iOS device is already in recovery mode, you can proceed immediately to step 6.
       1. Disconnect the USB cable from the iPhone, iPad, or iPod touch, but leave the
           other end of the cable connected to your computer's USB port.
       2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds
           until the red slider appears, then slide the slider. Wait for the device to turn off.
                  * If you cannot turn off the device using the slider, press and hold the
                    Sleep/Wake and Home buttons at the same time. When the device turns off,
                    release the Sleep/Wake and Home buttons.
      3. While pressing and holding the Home button, reconnect the USB cable to the
           device. The device should turn on. Note: If you see the battery charge warning,
           let the device charge for at least ten minutes to ensure that the battery has some
           charge, and then start with step 2 again.
      4. Continue holding the Home button until you see the "Connect to iTunes" screen.
           When this screen appears you can release the Home button:
      5. If necessary, open iTunes. You should see the following "recovery mode" alert:
      6. Use iTunes to restore the device.
    If you don't see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.
    Additional Information:
    If you have a problem getting into recovery mode then try: RecBoot: Easy Way to Put iPhone into Recovery Mode.
    Note: When using recovery mode, you can only restore the device. All user content on the device will be erased, but if you had previously synced with iTunes on this computer, you can restore from a previous backup. See this article for more information.

  • Disc utility says it has repaired "X" but when immediately rerun says the same

    I run "repair pemissions" - it says it has repaired seven items.
    Without doing anything else, I immediately repeat the repair - with the same result.
    I reboot and run "verify permissions" - same seven items are "unrepaired".
    Can anyone tell me what exactly "repair permissions does"?
    I'm running OS X 10.7.3 on a 2.16 GHz core 2 iMac

    Although immensely popular, repairing permissions is a waste of time unless you have a specific indication of a permission error involving system files, which is rare, or a boot failure. It always spews bogus warning messages that mean absolutely nothing. The built-in help for Disk Utility says:
    Repairing disk permissions
    If you see an alert or a message that says your permissions are set incorrectly, you can correct the disk’s permissions by clicking Repair Disk Permissions.
    It’s not completely irrational to repair permissions after running a third-party installer, since such installers have been known to set incorrect permissions.

  • Disc Utility can't verify the HD

    Today i had a problem with an application hangging everytime i tried to load it. So i went to Disk Utility to verify permissions, but first I decided to do a verification to the disc.
    After 5 or 10 seconds i get an error saying (in spanish, so i will translate it) *Node structure no valid*.
    Does anybody knows what this means and how to fix or repair this?
    Thanks

    Yes, it means you hard drive directory is damaged and needs repair. See:
    Repairing the Hard Drive and Permissions
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
    If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    In the event you may need to reformat the drive, I suggest backing up your files ASAP.
