Volume Structure -90 error

I have run Tech Tools Pro, disk utility and nothing seems to touch this one. I can't optimize unless this is resolved. Any ideas what is happening that I can't seem to get past this error code?

Make sure you are running Techtool Pro 4.0.5 or later. If the latest Techtool Pro can't solve it, you might want to get Alsoft Disk Warrior 4.0 which now is Intel Mac compatible. Note, you should only work on machines which are backed up with any utility. My backup FAQ explains this and more:

  • Volume structure failed (error = -92)?

    what does volume structure failed (error = -92) mean?

    The flashing ? folder merely means it has no system folder it can see. A bad directory can cause this problem*:
    http://www.macmaps.com/directoryfaq.html
    The bad directory may also be the result of an automatic shutdown not happening properly like you described, so it is hard to know which came first, the chicken or the egg.
    It is also hard to know if the result of the bad directory has also rendered the power management preferences damaged, or if the power manager itself or battery is damaged.

  • Volume structure failed error #2 techtool deluxe

    Hello,
    can the volume structure be repaired if techtool deluxe cant repair it.I am having major issues here since the latest security update its taken me this long just to startup from TT disc

    Hi
    I believe you will need TechTool Pro, as I don't know if Deluxe can do it or not, or Alsoft's DiskWarrior to repair your disk if Disk Utility can't.

  • Error -694 Volume Structure???

    Ran tech tool cd and it could not fix volume structure error and showed error -694. Does anyone know what this means?
    Just archived and reinstalled OSX yesterday to fix a boot up problem, which it did. But now after doing the needed updates - whenever I try to type something in firefox a gray screen with the power button logo pops up and says I have to restart - and when I try to open multiple documents into photoshop it won't open them - only individually.
    So I figured something must be wrong - and ran the apple hardware test, disk utility and then the tech tool deluxe. Then I got the volume structure error which tech tool could not fix. Could it have something to do with permissions errors? I was trying to fix permissions and everytime I do, I get the same corrections which seems weird. Anyone got any suggestions?
    I have an imac G5 with OSX version 10.3.9. 1.8 Ghz with 768MB Memory.

    "I can still use my computer"
    STOP, you should not!
    "The privileges have been verified or repaired on the selected volume"
    The information you seek is in the details!
    There is nothing wrong with your permissions repair, which should be being done from the Disk Utility version located within your hard drive's Applications>Utilities folder, and not while booted from the install disc.
    HOWEVER - The problem is when you boot from your grey-labeled install disc and then run Disk Utility>First Aid>Repair Disk - apparently it is not able to make any progress at all and simply reports an error -694, is that correct? I would call AppleCare and give them that error code information along with the fact that you are seeing the grey restart screen. After you ran the Repair Disk procedure, did you look in the space below for the "S.M.A.R.T. status:" which should have showed "Verified" next to it? You should also report what that shows to AppleCare.
    I would not use the TechTool Deluxe CD for making repairs, except if Apple requires it, which I doubt they will. They will care much more about the results of Apple Hardware Test and the other symptoms that you are seeing.
    The grey screen that pops up demanding a restart is a kernel panic, caused by either hardware or software. Combining this with your Apple Hardware Test's error code about your hard drive, I think you should be prepared for the possibility that you may, at any moment, lose the use of your hard drive forever. Back up anything important, and do not store anything new on it.

    The error -694 message means that one part of your hard disk is listed as being part of two or more files; using the Disk Utility's Repair Disk option may identify these files.
    The output of the Repair Permissions command indicates that you're using a version of iTunes which the mechanism can't properly handle, and the others are status messages. You shouldn't be concerned about any of those messages.

  • Rebuilds, permissions, volume structure error/fixes ???....

    Just setup a new iMac with OSX4.8 of course. Loaded Adobe suite and MS office. Transferred a bunch of files from my prev Mac G4. So now, only 3 weeks into using it, I've got misc errors that show up when I run Drive Genius or Apple Drive Utility. In fact the Apple Drive Utility failed to repair. Drive Genius seemed to have more success after rebuilding first.
    I'm not a newby to Macs having used them since '84, but I got to say, I'm a little on edge with these file/volume/structure issues or whatever.
    Can one of you experts out there describe in laymen's terms what are these volume/structure/rebuilds/etc error and fixes ? What causes these corruptions in the first place?

    Disk Utility starts to do it's thing then stops and
    shows "failure to complete". So went to Drive Genius
    to do more in depth analysis, the repair routine
    actually showed 3 tries then failure.
    Hi Thomas,
    This looks like you are running Disk Utility from your hard drive and if so, it cannot repair it because it is your startup disk. To repair your startup hard disk, you need to start up from another source like the install disk that you got with your new Mac.
    1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. In the left pane, delect your Mac OS X volume. (If you do not see it, click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.)
    4. Along the top of the right pane, Click the First Aid tab.
    5. below, Click Repair Disk. (Disk Utility checks and repairs the disk.)
    If it reports any errors, re-run Repair Disk until it reports no errors.
    6. Repair Disk Permissions.

  • Taking a stab at live help from a pro - disk volume structures

    I'm taking a stab at getting some live help on an a 1-month old iMac 24". I'm using my Mac mini right now because the imac is undergoing a TechTool Deluxe Surface Scan at the moment.
    Specs:
    1 month old Intel iMac 24 2 GB RAM 500GB Seagate HD...
    Everything's been fine. I added a firewire 800 external 500GB HD the first week, bought the registered version of Superduper, and have been making bootable images since. They work fine and the iMac is booted from it as we speak.
    System froze today quitting Firefox I believe. Had to manually boot with the power switch. Got grey screen, spinning circle (NOT the colored one), nothing else.
    Booted to OS X startup disk, ran disk utility, got error on disk repair. (Sorry, I don't remember what it was, but I don't think you'll need it after you hear the rest of the story).
    Booted to external Firewire 800 drive, ran disk utility again, same error, wouldn't fix it.
    I have Applecare on it, put Techtool Deluxe CD in, ran all the test except Surface Scan, everything passed except Volume Structure.
    Told it to repair, confirmed it, Wait a few minutes and Techtool Deluxe program acts like it's working, seems to unmount the internal HD, and just quits with no error message.
    bring up disk utility, same error when disk repair tried.
    windowsrefugee takes deep breath
    Now I reran TTD with Surface Scan checked, it's half-way through with no errors.
    Keep in mind, the only problem reported by TTD is with Volume Structure but it CAN'T fix it.
    Now, while it's in the middle of a surface scan that's looking good, here's my critical decision path question to any late-night guru's out there:
    Should I wait til morning and call Applecare, or download Disk Warrior for $99 and fix it myself (I'm new to Macs but a DOS and Windows old-timer with a high level of expertise).
    I'm boiled it down to those 2 options, simply because I don't think there is anything physically wrong with the HD, based on disk utility AND TTD telling me it's a volume structure problem (that neither one can fix).
    Plus, something tells me Disk Warrior is gonna come in real handy sooner or later (looks like sooner to me
    Do I have this right? What are the chances there is nothing physically wrong with the HD and what are the chances of Applecare fixing it over the phone without me having to take it to repair shop (or get a home visit if they do that-which is gonna be a hassle if I have to take in to shop as I'm disabled.
    windowsrefugee inserts a big PERIOD and thanks anyone in advance for their help.
    PS---I love the iMac, my Mac mini, OS X and all things Apple. My MS-based OS machines strewn all over the shop are getting very lonely for human interaction, but they're not getting any from me.

    nothing wrong with HD.
    I 'd suspect the third party applications. If you have the time and energy why not do a clean install and see what happens. You could run Apple Disk Utility to check that HD.
    One thing in the Mac world is always check version and compatibilty with the OS system version you are running. I've run Macs since 1986 and don't use any sort of Disk Utility. No sense in it. I've owned all the ones you mentioned and still waiting for the DEFINITIVE FIX.

  • Directory Scan and Volume Structure Failure

    My imac (white, 24") has been running slow and freezing up while attempting to preview files. Ran Disc Utility and OnyX, which gave me the following permission issues:
    Permissions differ on "usr/share/derby", should be drwxr-xr-x , they are lrwxr-xr-x
    Repaired "usr/share/derby"
    Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/
    But otherwise, both said the disk was fine.
    Ran TechTools failed the Directory Scan, Format Scan, and Volume Scan. I restarted from a second partition on the same HD. This partition passed all tests.
    I repeated all three tests on the original partition. This time, Disk Utility could not verify or repair the original partition and no longer recognized it as a valid startup disk. I erased the partition and restored from a Time Machine backup. Now, I get the following permission errors:
    Permissions differ on "usr/share/derby", should be drwxr-xr-x , they are lrwxr-xr-x
    Repaired "usr/share/derby"
    ACL found but not expected on "Library/Preferences/Audio"
    Repaired "Library/Preferences/Audio"
    ACL found but not expected on "Library/Preferences/com.apple.alf.plist"
    Repaired "Library/Preferences/com.apple.alf.plist"
    Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/
    And while once again OnyX and Disk Utility says the disk is fine, Tech Tools still reports a Directory Scan failure and Volume Structure failure. A subsequent Surface Scan passed.
    Ideas? Is this a software failure or a hardware failure? Both partitions are running 10.6.3. This is the second HD on this imac, the previous 750GB failed completely and could not be restored.

    It says permissions are repaired on those items, but when I verify permissions, they are still not right.
    See Mac OS X: Disk Utility's Repair Disk Permissions messages that you can safely ignore. It isn't that the permissions themselves are wrong but that the database of correct permissions on your hard drive the utility refers to has not been updated to reflect the permissions settings & directory structure changes in the most recent OS updates. This is a known issue that affects everyone, but as the article says, you can ignore it.
    Mac is not experiencing the same slow down on routine items as it was before, but TechTools is still saying there's a problem.
    What version of TechTools are you using? If it is not a current one it may not recognize the recent changes in the file system structure made in Snow Leopard.

  • Tech Tool Deluxe Volume Structure test query

    Hi,
    Sorry if this is elsewhere, but my searches have not supplied a definitive answer.
    As part of my regular maintenance routine on my iMac (mid 2010 i7 quad core) that I purchased just before Christmas, I have run the AppleCare Tech Tool Deluxe scans at regular monthly intervals with no problems, until about a month ago.
    When the program does it's stuff, all tests pass, except the volume structure one (in the window showing the image of the volume structure, it says fail! above the "icon"). The final report that Tech Tool Deluxe comes out with says everything has passed. What's going on?
    Because of this, I''ve also done a surface scan in the program and it was OK, as was verifying the disk in Disk Utility from the Snow Leopard DVD. I've repaired permissions and even reformatted the Macintosh HD and done a complete reinstall of the OS (not from backup), all of which come up with the same result in Tech Tool Deluxe - volume structure fails, but final report passes.
    The version of Tech Tool Deluxe I have installed from the AppleCare disc is 3.1.3, which according to Micromat is the current one, but this is from 2009.
    So my question is this:
    Has the updated Snow Leopard (10.6.6) changed it's volume structure slightly meaning that Tech Tool Deluxe thinks there's a problem as it's scanning, but then ignores it for the final report, or is my HDD failing?
    I've not noticed any issues whatsoever with the iMac and I have both Time Machine and bootable SuperDuper backups, so I'm not worried about my data.
    Would you guys recommend ignoring it for now, or should I get Diskwarrior to check it out further?
    Thanks for any help, or light that can be shed on this issue.

    Hi Den,
    Thanks for this, I emailed them and they are giving the usual story of "this product was developed for Apple, so you'll need to speak to them".
    I've bit the bullet and purchased DiskWarrior 4.3 and by installing it onto my SuperDuper backup drive, I was able to check out the iMac's internal HD.
    DiskWarrior was able to find errors in file structure and permissions etc (it didn't give details) and was able to repair them. After rebooting into the internal HDD, I ran TechTool Deluxe 3.1.3 again, and this time it said that it failed the volume structure during the test and then in the final report. It tried to get me to download the repair version of the software, but the web page that opened had nothing to do with TechTool's download. As a little self test, I ignored it and ran the test again. This time, it failed during the test (as normal) and then said that it passed in the final report.
    I have therefore come to the conclusion that if Disk Utility AND DiskWarrior say that it's fine, then the issue must be with TechTool Deluxe. At least it doesn't seem to be an issue with the actual drive.
    I admit that I was getting suspicious of TechTool when a fresh install on a reformatted HDD said that the volume structure failed and then passed. There must be something different about the current version of Snow Leopard comared to that at the time of release of version 3.1.3 of Tech Tool Deluxe.
    Thanks for all your help guys.
    Obviously, if someone can prove me wrong, that would help me ascertain as to what is going on.

  • IMac btree or volume structure problem?

    When I turn on my 8 year old iMac I get a gray screen with the Apple logo and a narrow horizontal bar just above the logo. I tried doing a Safe Boot, but after a few minutes it restarts itself. I started it up from various CDs that came with it, and these are the results:
    Apple Hardware Test CD shows no hardware problems.
    OS 9.1 CD got me to the System 9 desktop. I ran Disk First Aid from the CD. The last item it checked was catalog BTree. Right after that it said unable to read from disk. I was able to copy items from the System 9 desktop to my laptop. But when I opened the Users folder on the HD to copy items from the OS X side, all I found were .localized documents. I was hoping to get to my pictures.
    OS 10.0.3 CD Disk Utility - First Aid said "Reserved fields in the catalog record have incorrect data. Keys out of order." When I click Repair, it does not fix the problem.
    I then downloaded Tech Tool Deluxe for Power PC and started up from that CD. It says Volume Structure failed. If I choose to rebuild, it will make some drastic changes to the original directory data, such as total files going from 193,111 to 8,595 and volume content size going from 18.6 GB to 12.1 GB. I was afraid I might lose something important, so I did not do the rebuild.
    I feel like I might be in over my head. Should I take it to the Apple Store and let them deal with it? Any ideas about how to get to my pictures so I can copy them onto my laptop?
    Thanks!
    April

    +Keys out of order+, in my experience and others here, can only be repaired with the following utility and only if it's not too far gone. It repaired that issue for me.
    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.
    TechTool is just not a robust enough repair utility to fix your very serious directory corruption.
    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
    p.s. Here's a rewiew of DiskWarrior 4.

  • 10.5.8 update corrupted the Volume Structure of my MacBook Pro and iMac

    After installing the 10.5.8 update on my Macbook Pro AND my iMac, BOTH computers refuse to boot up. If I boot from a TechTool Deluxe DVD and run the system scan, It fails both the Directory Scan and the Volume Structure test. The only common application on these computers is the Fusion PC emulator. I was reading that the newest update fixed problems with this application. PLEASE HELP!!!

    Some general advice on updating:
    It is worth noting that it is an extreme rarity for updates to cause upsets to your system, as they have all been extensively beta-tested, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
    So before you do anything else:
    If you can, make a full backup first to an external hard disk. Ideally you should always have a bootable clone of your system that enables you to revert to the previous pre-update state.
    Turn off sleep mode for both screen and hard disk.
    Disconnect all peripherals except your keyboard and mouse.
    1. Repair Permissions (in Disk Utility)
    2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
    At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
    3. Download the correct version of the COMBO update from the Apple download site.
    The Combo updater of Leopard 10.5.8 can be found here:
    http://support.apple.com/downloads/MacOS_X_10_5_8_ComboUpdate
    If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
    Full details about the 10.5.8 update here: http://support.apple.com/kb/HT3606
    More information on using Software Updater here:
    http://support.apple.com/kb/TA24901?viewlocale=en_US
    Using the Combo updater ensures that all system files changed since the original 10.5.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.5.7 to 10.5.8. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
    Now proceed as follows:
    4. Close all applications and turn off energy saving and screensaver.
    5. Unplug all peripherals except your keyboard and mouse.
    6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
    7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
    8. Once your Mac is awake, repair permissions again, and you should be good to go!
    If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious!
    9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them compliant with the latest version of your operating system. Give them a weeks or two while you regularly check their websites for updates. This applies particularly to plug-ins for Safari 4.
    N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
    Lastly, Apple's own article on the subject of Software Update may also be useful reading:
    http://docs.info.apple.com/article.html?artnum=106695
    If you are updating Safari (or just have):
    Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up. If you have installed an OS update and Safari is crashing, the very first thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
    So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari.
    Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party add-on.
    Additional tips on software installation here:
    http://docs.info.apple.com/article.html?artnum=106692
    To reiterate, Input Managers reach right into an application and alter its code. This puts the behavior of the affected application outside the control and responsibility of its developers: a recipe for problems. That's not to say that issues absolutely will ensue as a result of Input Managers, but you, as a user, must decide. If the functionality of a specific Input Manager or set thereof is really important to you, you may well choose to assume the associated risk.
    Again, the advice is to remove all Input Managers from the following directories:
    • /Library/InputManagers
    • ~/Library/InputManagers
    especially prior to system updates (they can always be added back one-by-one later).

  • "Volume Structure Failed" in TechTool Deluxe

    I tried to run Disk Utility on my laptop last night and it said that it "stopped reapiring "XXX" because the following error was encountered. The underlying task reported failure on exit (-9972)" It said there was an invalid catalog record type and volume check failed.
    I then ran the lastest update of the TechTool Deluxe CD. Everything passed except the Volume Structure.
    There were some "used nodes" and "free nodes" that differed--those numbers showed up in green as "favorable changes". "Leaf Record Count" showed up in red as an "unusual change". When I go to repair, it says that "unusual values in the volume structure have been dectected. Before repairing the volume structure, it is suggested that you back up your data. FAILURE TO BACKUP YOUR DATA MAY RESULT IN PERMANENT LOSS OF DATA!".
    I do have a Retrospect Backup on my external drive, but I'm still a little nervous about clicking the "repair" button. How likely is data loss with this particular error that it's trying to repair?
    I'd like to call Apple Support (I'm still under AppleCare for another week or so), but I'm not sure if they have Saturday hours.

    Okay, here's what I ended up doing. I did end up calling Applecare Tech support, but mostly only to inquire about potential coverage if I needed it--since I was one week away from the expiration of Applecare. They opened a "case" for me and Applecare would remain in effect for 30 from the opening of the case. This was good news.
    I tried using Disk Utility to repair the problem but it wouldn't work. I had repaired permissions and attempted to run “Check and Repair Disk”. Disk Utility said that it “stopped repairing ‘xxx’ because the following error was encountered. The underlying task reported failure on exit (-9972)”. It then said that there was an invalid catalog record type-volume check failed-volume was not repaired.
    A friend of mine has DiskWarrior for Panther so we were going to try that before trying the TechTools Deluxe CD that I had just updated from the Apple site.
    Went over today to do that. Unfortunately, we couldn't get the computer to boot up with the DW disk. It would boot up with the Install disc & TTD, but not DW. We tried booting with the option key. It did show that we could boot from "utility CD", but the minute we hit the arrow key after selecting it, we got a circle with a slash through it. We called DW support and they said that my computer was newer than the CD. This was strange since my friend's larger G4 Powerbook was only a couple of weeks older than mine and DW works fine on hers.
    Anyway, we ran TTD and let it repair. Ran DU again and it still showed a problem that it could not repair. Ran it again--same thing. Ran TTD again--just to test. It showed that there was nothing that needed repairing. Ran DU yet again--3rd time for the afternoon. Did repair permissions first, then Repair Disk. Strangely enough, now it said the volume was fine and needed no repairing.
    So, at least for the moment, things seem okay. Not sure exactly which step worked or if it was just a combination, but I'm just happy that it finally passed DU check.
    I will continue to monitor for the next few weeks.

  • Volume Structure Failed message

    When I run the Techtool Deluxe software on both hard drives, the original hard drive from Apple and another WD 320 drive I bought and installed I get the Volume Structure Failed message on both and Techtool Deluxe cannot repair either. Anyone have ideas on what is causing this problem and what it means?
    Volume Structure
    Failed
    TechTool Deluxe can scan volumes for problems related to the numerous structures that are necessary for the volumes to operate correctly. If problems are found, TechTool Deluxe can attempt to repair the damage to help reduce the chance of future problems.
    If TechTool Deluxe has discovered problems with the volume structure of a volume, allow the program to repair the problem. Quite often these issues are minor, but sometimes they can be indicative of a more serious problem. If the problem persists, consider backing up the device, reformatting the media, replacing the data, and then testing again.

    Disk First Aid's repair process only works on a single pass basis. That is, it will make a pass, and attempt to repair the first problem it encounters, then exit. In order to successfully use Disk FirtAid's repair process, you must perform the repair numerous times, until no error message is displayed.
    When Disk First Aid completes without any error message, then any repairs were performed successfully. If the error messages always continue, then it was unable to make the needed repairs.
    The only problem with this process is, how many times to try the repair process before giving up, since the process doesn;t give you any idea of many more passes will be needed. You know a message, like, "Hey, almost done, maybe two more passes" would be helpful.
    Instead you just need to guess, and if it takes more then four or five passes, it is probably beyond the ability of Disk First Aid to repair. However, it is still possible that fsck (file system check) may be able to complete the repair that Disk Utility was trying to fix. Actually Disk Utility uses the fsck program, but fsck when run from the single user mode can be more effective, since the file system can be completely unmounted and checked.
    To run fsck from single user mode, restart your Mac and hold down the Command key plus the S key (apple key and the S key held at the same time while restarting). The screen should show lines of text flowing by ending with a command prompt. at the command prompt, enter /sbin/fsck -fy and hit return.
    If problems are encountered an repaired, a message saying FILE SYSTEM WAS MODIFIED will appear. Like Disk First AId, you need to run fsck multiple times until the above message is not displayed and instead a message says the volume xxxx appears to be OK appears. When this happens, or when you decide that no amount of running fsck will work, then at the command prompt enter reboot and hit return.
    Good luck.

  • Volume structure, surface scan

    I have a new imac, it's been with me for about 2 months total. I noticed some silly little things happening occasionally....so I used tech tools and did a scan. The volume structure failed....and the surface scan has 2 errors.
    What's the significance of this? What should I do?

    Probably nothing. If you used TT Deluxe I would not rely on it's results. The standard repair tool is Disk Utility which is in your Utilities folder. If you need to repair your drive do this:
    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 and/or Tech Tool Pro 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.

  • How to fix failed volume structure

    I ran tech tool deluxe and got the diagnostic that the volume structure failed the test.  Tech Tool Deluxe doesn't offer an option to "fix" this problem.

    Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
    /sbin/fsck -fy
    Repeat until it shows no errors fixed.
    (Space between fsck AND -fy important).
    Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

    Just recently I ran into a problem when I tried to Verify my hard disk and when it tried to verify the catalog, it responded "Invalid sibling link." Repair Disk didn't work. I searched the web and Apple's site, and couldn't find anything useful except to buy DiskWarrior or reformat the drive. Knowing that OS X is built on Unix gave me a few clues on how to proceed. The solution is pretty simple:
    Boot off the OS X CD (reboot, hold C while booting).
    The installer will load up, go to Utilities in the menu and run Terminal.
    Type df and look for the drive that has your Mac system mounted---you'll have to unmount this. On my MacBook Pro, it was /dev/disk0s2.
    Type umount /dev/disk0s2, replacing disk0s2 with whatever disk your OS lives on.
    Type fsck_hfs -r /dev/disk0s2. If you umounted the wrong thing, it will complain that you can't repair a mounted drive. Go back and umount the right thing and repeat this step.
    Just for fun, you might want to run another fsck_hfs on your disk (use the -f option because your drive is probably journaled). Hope this helps someone so they don't buy a program that's going to do pretty much what we did with fsck_hfs, and so they don't waste time searching for an answer to no avail. By the way, TechTool Deluxe (3.1.1) didn't find the Catalog problem for some reason (you'll have this on a CD if you have AppleCare), which is why I resorted to fsck.

    Your best bet is DiskWarrior, you need the CD/DVD though.
