Invalid Sibling Link Encountered during Leopard Install

Help! - I have two Intel 20" iMAC's running Tiger 10.4.10 (1GB mem/250MB HD). I used the Leopard family pack to successfully install Leopard on one computer. However, the Leopard install process has crashed my second computer.
I left for 45 minutes after starting the 2nd install. When I returned there was a yellow triangle on the screen warning of an installation problem and telling me to click to restart. When I did the Apple logo and spinny circle appeared for a minute and then the computer shut off. I've run disk utility and now get the following message.
Verify Disk
Invalid Sibling Link
The volume Mac HD needs to be repaired
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
Mount Point: Not Mounted
Format: MAC OS Extended (Journaled)
I have tried disk repair from disk utility and fsck_hfs -f from the terminal window. Neither has helped, I continue to see the invalid sibling link error.
What can I do other than reformat and clean install. I have data I want to backup first, then I don't mind doing a clean install. Also I would like to deauthorize my iPod.
Any help is greatly appreciated.

+Invalid Sibling Link+ can usually be fixed by the following utility......
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.
I use DW once a month to try and catch errors in my system from getting too far out of hand. It has repaired every little and big issue I have ever had with my three Macs.
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!
Good Luck! DALE

  • Invalid sibling link?

    Hi,
    Today my macbook pro started powering down after hanging during the boot process. going to verbose mode, i noticed an "invalid sibling link" error during the drive check, just before the cpu halted. the hardware diagnostics say nothing's wrong with the hardware.
    I tried booting into single user mode, and running fsck_hfs -r, but that gets to the same point and throws an error, and i still cant boot. i cant get an appointment with the apple store until monday, and i have school work to do. what can i do to address this problem?
    oh, and i've tried booting to the install disk but for some reason that doesnt work. the drive spins up and then it goes to the gray apple screen, which hangs and then powers down.
    suggestions?

  • How can I fix an invalid sibling link error message without my original install disk?

    How can I fix an invalid sibling link error message without my original install disk?

    Hi Jeff,
    It's not even likely the Install Disc could fix that, but if you want to try...
    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...
    http://docs.info.apple.com/article.html?artnum=106214
    You must repair the HD, your best bet is likely DiskWarrior.

    Finally, you should run DiskWarrior if your Mac explicitly warns you of a problem with your disk in the form of an error message. Most of these errors are reported by the built-in Disk Utility whether your Mac OS X version is 10.3 Panther, 10.4 Tiger, 10.5 Leopard, 10.6 Snow Leopard or 10.7 Lion. Here are some of the most common messages:
    Disk Repair: The disk was not repairable by this computer. It is being made available to you with limited functionality. You must back up your data and reformat the disk as soon as possible.
    The underlying task reported failure on exit.
    Invalid node structure.
    Keys out of order.
    Invalid key length.
    Invalid directory item count.
    Invalid extent entry.
    Invalid record count.
    Invalid index key.
    Invalid sibling link.

  • Errors when installing os x 10.4- Invalid sibling link-volume check failed

    I am trying to upgrade my PowerPC G4 from OS x 10.2.8 to 10.4. I bought the Tiger Retail DVD. The install disc boots and runs, but near the end of installation, I get " Error Installing Software- Please try installing again" I opened the disk utility on the installer and tried first aid- which failed.
    "Invalid Sibling Link"
    "Volume check failed"
    Error: The underlying task reported failure on exit
    HFS volume checked
    1 volume could not be repaired because of an error
    I tried first aid repeatedly with no luck. I tried the fsck repair suggested in one of the discussion forums "fsck -fy"
    again, "volume check failed"
    I'm looking to buy DiskWarrior as suggested, but am curious about another option I've read about. I found a macosxhints website http://www.macosxhints.com/article.php?story=20070204093925888
    that suggests running the install disk, clicking on terminal and unmounting the drive that the OS system "lives on". If I do this, will I lose the data already on my computer? The hint does not talk about how to remount the drive.
    I am NOT computer savvy. Would this be getting in over my head? It sounds simple enough, but I don't want to do any irreversible damage. Should I just buy disk warrior, or would the safest bet be to buy an external hard drive and back up everything, then perform an erase an install with Tiger?
    Any help would be MUCH appreciated!!!

    Hi confused- I just fixed my invalid sibling link error on my HD. Stop using your HD!
    It will only get radically worse. I went to http://www.alsoft.com/DiskWarrior/ to see which version of Disk Warrior I needed which was 4.1. Then I went to a retail store & bought the CD $99. On the box, it must say 4.0 with 4.1 included + CD rev 42. You must use the CD as the download won't boot up your HD. In the box is a 1-pager of simple instructions. Put disk in CD drive, follow instructions, click rebuild HD, wait 15 minutes. My HD is perfect!!!now. It fixed permissions, rebuilt my directory, fixed my CS3 Adobe applications, fixed corrupted prefs, found & restored ALL files. I lost nothing! Plus made a PDF detailed report. Best $99 i ever spent. Good luck!

  • Start-Up: Folder with gray question mark / Disk Utility: Invalid Sibling Link

    Yesterday, I was working on my computer and it froze up. My only option was to reboot by holding down the power key. When the computer restarted, the screen was all grey with a folder in the middle of the screen with a question mark.
    I tried the following:
    1) Boot up computer while holding down the "Option" key. - Didn't work.
    2) Boot up the computer while holding down the "Shift" key. - Didn't work.
    Since the first two options didn't work I inserted the original system install disk and booted up while holding down the "C" key. I selected "English" as the language and then opened "Disk Utilities." I pressed "Repair disk" within First Aid. The message I am getting is as follows:
    "First Aid failed. Disk Utility stopped repairing "Macintosh HD" because the following error was encountered: Filesystem verify or repair failed."
    The details screen shows the following:
    "Verify and repair volume "Macintosh HD"
    Checking Journaled HFS Plus volume.
    Checking Extents Overflow file.
    Checking Catalog file.
    Invalid sibling link.
    Rebuilding Catalog B-tree.
    The volume could not be repaired.
    Error: Filesystem verify or repair failed."
    I ran the "Repair disk" function about 6 times but it was not successful.
    I was then going to try to do an "Archive and Install" from the original system disk but when I go to do that no destination options appear at the "Select Destination: Where do you want to install Mac OS X?"
    I have not backed up my data very recently (and a lot of what I have stored on this computer is work - I am a freelance designer) so I would like to do something that at least allows me to transfer my data off of my hard drive before reformatting or anything like that. Of course, if there is a less intrusive fix that can leave my hard drive in tact, that would be ideal.
    Any advice? Tips? Solutions? I have a MacBook Pro, 15" that I purchased 3 years ago (my 3 year Apple Care plan just expired about a month ago).     

    You are in a tough situation.  The disk appears unusable according to Disk Utility.  As was suggested you may (only may) be able to salvage it with Disk Warrior (not sure about Data Rescue).  DW can sometimes recover a drive that DU can't.  But nothing else can be suggested. 
    If you can get that disk recovered then back it up ASAP, wipe the disk, reinitialize it, and verify it.  But I'm the paranoid type, and with the kind of errors you show for that disk, I am not sure I would ever trust it again.  At most I would relegate it to a scratch disk.
    Note, if it is a drive that you bought, most drives have a 3 to 5 year warrantee period, so you could get it replaced by the manufacturer if it is within that warrantee period.

  • Invalid Sibling link, Crashing, Unmounted HD?

    I convinced my friend to purchase a mac because I have yet to have a single problem with mine. I fear that perhaps I lead him astray because he has had a slough of difficulties. Perhaps the quality standards at apple have faltered?
    He has a Mac Book Pro (purchased 2 months ago perhaps?) with 10.4.9
    This is the problem he has:
    The computer froze while using the internet. After shutting it off and turning it on again it progresses to the gray screen with that little circle, the chime is heard, and then it shuts down after a minute by itself.
    When using the installation disk it does not recognize the hard drive in order to install. When using disk utility, the following occurs:
    When verifying the volume:
    verifying volume
    checking hfs plus volume
    Checking extents overflow file
    Checking catalogue file
    Invalid Sibling link - this is displayed in red
    The volume (macintosh hd) needs to be repaired. Error. The Underlying task reported failure on exit. (1 hfs volume checked, volume needs repair)- This is also in red
    Then, in pop up window:
    First aid failed. Disk utility stopped verifying (macintosh hd) because the following error was encountered: The Underlying task reported failure on exit.
    When verifying the said volume, the same errors are given:
    verifying volume
    checking hfs plus volume
    Checking extents overflow file
    Checking catalogue file
    Invalid Sibling link - in red
    and so on...
    He also noticed that the hard drive appears to be unmounted. Is this normal? When he pushes the mount button he says it does not make any difference.
    Any help? Please?

    If Disk Utility is unable to repair the damage, which is not entirely surprising, then you're going to have to resort to a more capable tool like TechTool or DiskWarrior.
    One thing you can do is to connect his MBP to yours using FireWire Target Disk Mode…
    http://docs.info.apple.com/article.html?artnum=58583
    … as this may make life easier as you'll be able to install these tools to your MBP.
    Regardless, directory damage is always a possibility whether you use Mac OS X or Windows. The trick is to avoid a hard shutdown as much as possible as this is a common cause for such damage.

  • Invalid sibling link error

    I have a 15" PB which gave an "invalid sibling link error" one month ago and I was not able to even repair it using DiskWarrior. I have Apple Care Protection plan, so I sent it for repairs and the repair guys replaced the motherboard as they suspected it was the reason. On return, I reformatted the HD and installed everything from stratch. Everything was working fine till last Saturday morning, when computer would not boot up. So I checked using Disk Utility from PB DVD, and the dreaded "invalid sibling error" came up again. Since I have a bootable backup of the HD, I formatted the HD and tried to load the system on the HD from the backup copy. But the writing of backup using CCC hung up and I had to quit it. After that I was not able to find the HD using Disk Utility from DVD.
    I have sent it for repairs again, but can anyone help me understand the core problem here. Since last time they replaced the motherboard, I think they will replace the HD this time around. Is the logic board, motherboard or the HD that is the root cause of the problem?
    Powerbook G4   Mac OS X (10.4.7)   100GB HDD, 1.5GB RAM

    I had never heard of "invalid sibling link error" until you post, and when I ran a search on it the best explanation I could find is that it is a directory-related problem. See the following (assuming it is correct): http://www.computing.net/mac/wwwboard/forum/2584.html The suggestion there, though, is that DIsk Warrior should be able to fix the problem, and you've already told us that you tried using Disk Warrior on it and it did not work.
    Very puzzling. Please post back what happens when you get your PB back from being repaired.
    Good luck.

  • Macbook not starting up - Invalid Sibling Link

    Hi,
    I have a Macbook Pro 13 inch (Early 2011). It refuses to start up anymore. I have done the following tests/checks
    1. Try booting into safe mode. It gets stuck there as well.
    2. Boot into single-user mode and run fsck. It get a "Could not repair Macinotish HD" (or something similar, I ran this a long time ago and am recalling what it said)
    3. Booted using the OS X Install Disk, and ran Disk Utility. Tried repairing and got
    Invalid sibling link
    Rebuilding catalog B-tree
    The volume Macintosh HD could be repaired
    Volume repair complete.
    Updating boot support partitions for the volume as required.
    Error: Disk Utility can't repair this disk...disk, and restor your backed-up files.
    4. I also ran fsck_hfs -r as some sites suggested, but this didn't work either.
    I believe this is not a hard disk fault, since I can boot into my Windows partition without issue.
    Is there any way to fix this problem WITHOUT having to reinstall the OS?
    In cases reinstallation is the only option, how do I go about backing my data? Should I create a New Image (using Disk Utility) and back up everything on an external HD? Won't this also image the corrupted part?
    Here's my problem with reinstalling the OS. I have a software that I have absolutely have to use in 3 days. However, I do not have access to the installation disks for that software. Thus, I would really not like formatting my HD. If I back up my data using the New image feature above, can I retrieve that software?
    BTW, I also have access to another Windows laptop, if that will help at all.
    This is a time urgent matter and I would be grateful if I get a reply asap. I really need my laptop to work. Thanks a lot!

  • Disk Utility- Invalid Sibling Link

    I had a similiar problem and posted this
    http://discussions.apple.com/message.jspa?messageID=3486224#3486224
    I have erased and installed the complete system (10.4) again and only been using Safari and ichat for a few days. I have updated all software etc.
    I was about to migrate all my files back from an External HD FW and decided to Verify the disk quickly and this message came up.
    Do i have to buy another hard drive?
    If so what do you recommend? (about 250gb)
    G5 2.3DP   Mac OS X (10.4)   G3 Pisimo 400, Maxtor 250gb External FW HD, ipod etc

    If you have erased (but not zero'd the drive) and re-installed 10.4 after the first problem, and then it has happened again, you could try an erase with zeros (select 'Security Options' in Erase) and a complete new install of 10.4 and combo update to 10.4.8
    http://www.apple.com/support/downloads/macosx1048comboupdateppc.html
    'Zeroing' is supposed to map out the bad blocks on the drive so that they are not used.
    When you have re-installed, you could run Disk Utility(the one on the 10.4.8 drive) and Verify Disk on the boot drive a couple of times. If there is any sniff of an error, see below.
    But you may feel happier to replace the drive, as they are not that expensive. I have a Seagate 300GB as the second, 'data' drive, which was a good size/price combination at the time of purchase, but you may want a smaller, faster one as your boot drive. You will find many recommendations if you browse/search the forum.
    Note that it is not impossible that other problems are causing the directory corruption - but getting the drive running right would be my priority. Good Luck.

    This is a directory issue that Disk Utility cannot fix. Although it manifests itself as a software issue sometimes it may be hardware based. See DiskUtility reports "Underlying task reported failure" when repairing avolume http://support.apple.com/kb/TS1901?viewlocale=en_US". You can try using a utility like TechTool Pro, Drive Genius or Disk Warrior to repair and replace the directory. Another option would be to use the Archive and Install feature to reinstall. If the problem returns after correction you may have a failing or failed HDD.

  • Re: Invalid sibling link came the reply

    Hi Folks, I have a big problem, I was saving a document when the spinning beach ball arrived.
    The computer just quit, i've never had Mac quit like that before.
    I ran Disk Utility, (Invalid sibling link came the reply) I can see the drive greyed out, I highlight the
    drive, the blue Mount button lights up but the HD doesn't mount.
    I re-booted from my Diskwarrior cd and that way managed to bootup from an external HD.
    I ran diskwarrior. When I reached the point to replace the directory I get a flag telling me that there
    is not enough free disk space to perform a fail-safe replacement of the directory.
    Does anyone know: How much space is required to replace the directory (I have 2.5 gig available)
    Is there a way to pull stuff off the HD. !!!!
    At this point I think a couple of glasses of vino calapsso is what I need.
    What can I do next. Thanks very much in advance.......... B Taylor

    Hi-
    Does anyone know: How much space is required to replace the directory (I have 2.5 gig available)
    Oh my! 10 to 15GB minimum free space, or no more than 80% capacity. You have problems....
    At this point I think a couple of glasses of vino calapsso is what I need.
    No, you need another hard drive.
    Buy a new hard drive, and install it in the other hard drive bay. Format the new drive with Disk Utility, and install OS X. Boot to the new drive, and then you can move files to the new drive.

  • Error: Invalid sibling link...what to restore and what not to restore

    I am two weeks from having done a reinstall and partial restore. My system has been locking up again frequently and my Disk Utility shows this error.

    When I did my previous restore, I only had a limited back up to my iMac account available. Just address info, stickies notes, iCal, preferences and Keychain data I think. Because a similar problem is recurring so quickly, my assumption is that I imported the corruption back in to my system.
    First, is this a good assumption? Second, my system is still slighty operational now, so I was wondering what from my new back ups I should restore after a reinstall and what I should leave alone.

    Boot in safe mode. Hold down the shift key when powering on the machine. This will run a disk repair program.
    See this article:

    You will need to boot from you installation disk. I have not done this, but here are some hints:

    Or from mrtotes article :
    Boot from the OS X Install disk and from the Menu Bar choose Disk Utility. Then run "Repair Disk" and "Repair Disk Permissions" on your hard disk.

  • Invalid Sibling Link & Catalogue Errors

    Alright. First the MBP: It's got 10.4.7 installed on a 72gb partition with WinXP SP2 (running MacDrive) filling up the rest of the 100gb. I left the MBP on last night to download a couple files and nothing seemed worng with it. I shut it down and took it to work where I used Windows all day without a problem. I shut it down again and brought it home. Left it to boot into OSX and when I came back I was looking at a bunch of Unix command line speak. Lots of 'file not founds' and the three big scary ones: A couple about checksum errors (mach should be 1, found 0; mach.sys should be 147 found 47) and one invalid sibling link.
    I booted from the install disc and ran Disk Utility's Verify and Repair. Both crapped out early citing the three scary errors and an internal error that prevented it from completing. I immediately tried backing up my OSX Partition to an external. That went swimmingly until the end when it simply said, "An error has occurred Error -3087" (don't quote me on these exact error messages, I'm now doing this from memory. read on and you'll see why)
    I booted into single user mode and attempted to fsck the problem away (following the suggestion from http://docs.info.apple.com/article.html?artnum=106214) but that too met the same fate as Disk Utility, failing on the Catalogue check.
    Now, really frightening things are happening. I boot it up into Verbose mode to see what's happening and it simply repeats "SATA PROBLEM Completing a zero block transfer." ad inifinitum.
    The weirdest thing about this whole thing is that Windows still boots and operates flawlessly. With MacDrive I can still look at all my OSX files too. Opened up a couple movies and mp3 which worked fine.
    Helps me please!

    Shaun,
    You have suffered a major disk error. This doesn't mean that your HD is "fried," only that the file system on that one volume (the one with OS X) is damaged. It happens.
    Since you can boot into Windows and access that volume using Macdrive, I recommend you use that facilty to make a backup of your HOME folder on the OS X partition by copying it, preferably to an external drive.
    Based on the fact that this is a new machine, you might have a bad block on the HD. This is common with new HDs, in my experience. If a format (erase) of the OS X volume and a reinstall doesn't work the first time, you might need to consider "zeroing" the entire drive. Yes, including the Windows volume. By choosing the drive (or "device," as it's called) in Disk Utility, then "zeroing" the drive, Disk Utility will "map out" any bad blocks that are on the drive, thereby helping to prevent further disk errors. Many of us like to do this with any computer, right out of the box. It avoids having to go through what you now must.
    If you need instructions on doing any of this, just ask.
    Scott

  • "Invalid sibling link" prevents my computer from starting up

    I have a MacBook Pro running 10.4.10, and recently it crashed and restarted itself. As usual, I got the gray Apple logo screen with the spinning progress indicator, but after a couple of minutes of this the computer simply shut off. This happened again repeatedly when I tried to turn the computer on.
    I booted from my TechTool Pro DVD, and all of its hardware and drive tests passed, but it couldn't see any volumes on my hard drive! (My hard drive consists of one big partition, HFS+, not journaled... the standard MBP setup, I think.) I started up from my Mac OS X install CD and ran Disk Utility. DU could see the volume, but upon verification informed me that I had an "invalid sibling link" and then that the "underlying process crashed on exit". Trying again to verify and repair gave the same result.
    I am planning to take my computer to an Apple Store in a couple of days, but obviously it would be a lot nicer if I could simply fix the problem myself. Other forum posts about this error have inevitably ended with recommendations for DiskWarrior, but I can't even start up to run such a program! (I don't have DW installed, but would certainly pay $100 to fix this problem, if necessary.) Any advice?

    DiskWarrior is well worth the expense and is probably the best thing to use for an an *invalid sibling link* problem.
