MacBook :: Invalid Node Structure And Invalid Sibling Links On Hard Drive?
Jun 22, 2012
I'm having some trouble with my Macbook. It's running on Leopard 10.5.8. I recently tried to partition my hard drive and while doing so it prompted me informing me that there was an 'invalid node structure'. I could then no longer proceed with the partition. I had planned on updating my OS to Snow Leopard. I wanted to partition my internal HD, so I backed up some files on my external HD. I basically wanted my interal HD to run smoothly with a new OS while minimizing the space used. Now I've come across this issue where there is another message being prompted that says, 'invalid sibling links on hard drive'. I found THESE steps on another forum that informed me that this might restore the hard drive back to a readable/functional state but that didn't work either:
(These were the steps I took and nothing happened except another prompt informing me of an 'invalid node structure')
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.
I then stumbled upon a few different forums mentioning something about Disk Warrior. I was wondering if THAT would resolved this issue. Honestly, I don't really want to spend much money on buying this but I WILL buy a new hard drive if I ABSOLUTELY need to. I was just trying to see if I can troubleshoot this before I decide to throw in the towel and buy a new hard drive or attempt to try out this Disk Warrior thing.

Two days ago my MacBook (OSX10.4) crashed; VLC player froze when I was watching a tv show. I though 'no biggie, happens now and then' and hard-resetted my 'book. Tried opening the file again with Quicktime, again, computer froze up. Waited a couple of minutes, hard-resetted my laptop again. Only this time, the screen got stuck on grey/lightblue-ish screen during boot-up.
Tried a lot but couldn't get my MacBook up and running again. Started up with the OSX cd popped in and went to Disc Utility. Mac then told me there was a 'Invalid Node Structure' and that 'The volume could not be repaired'. During a third or fourth start-up this changed to Mac saying there was a'sibling error'.
I checked some sources online, figured out this should be something fixable. One possible option was Disk Warrior. Supposed to be *the* tool with problems like these. I replaced my malfunctioning HD, put an old HD in my MacBook, reinstalled OSX and put the malfunctioning HD in a stand-alone case and connected it too my MacBook. As we speak DW is busy rebuilding the directory but it has been doing so for over a day now. I've read online that it can take a couple of days though. My HD is 250Gb with 30Gb empty space when it went kaput.
Now, there seem to be a couple of other alternative options. These lads talk about Tech Tool Pro - apparantly some other program that could help: [URL]
Then there's a couple suggestions/methods mentioned online that either involve booting up in single-user mode and type some code [URL]
Has anyone ever had their HD act up like this? Any experience/recommendations regarding the programs/methods mentioned above? I'm pretty new with Mac (used PCs for ages, switched to Mac quite recently) and I'm kinda at wit's end here :/. I was in the process of backing up my stuff, but there's a boatload of data on that HD that I hadn't archive yet.

I recently dropped my even a couple of drops of diet coke near the DVD drive of my MacBook (2009).Turned it off immediately and turned it upside down for a bit. Tune it back on and it worked fine. However, the second time I turned it on it wouldn't go past the login screen. Turned it off as then on again, and started up fine. Ran a disc diagnostic and it gave me the invalid node structure message. From there it started to run slow so I shut it off again. Haven't turned it on since. I'm thinking of taking it in to a shop since I don't want to mess with it anymore.Is there any easy fix to this? If my hard drive is messed up, can I recover my data?

I've been using this external hard drive since Christmas Day and suddenly it doesn't work. I attempted to verify my disk and it came back with "Invalid Node Structure". I've been using this for Time Machine Backups but I don't mind losing them because there isn't really anything majot but I'm currently copying my two largest folders off there because it tells me I need to format my disk as soon as possible. How do I do that?

It is a 2008 intel iMac that had worked fine for the last four years until lion. Everytime there was and update or I rebooted, my Mac would freeze at some point of the login. A permission repair or just repair disk would solve the issue an everyone and a while, a restore from backup. Recently my Mac started to slow down to the point it froze for several hours and force quit would never open. I held the button and since then I have been in trouble. The repair permissions had a ton of errors but successfully repaired. But when I repaired the disk, it's hit a couple of errors but ultimately failed right after "Invalid Node Structure" that error has been consistent every time I have attempted a fix and it failed. I tried restoring from a backup to no avail. Then I wiped the drive and installed Lion (after a convienient 5 hours download) an it booted. I tried using it but it was extremely slow, let it sit over night and came back to it frozen. I had assumed it was slow due to indexing but after 12ish hours this didn't solve the issue. I clicked the apple button and it took a while to finally show up an restarted. Fro
There is wouldn't complete the boot. Froze at the apple logo or white screen with spinning mouse. Left that for several hours and stayed there. Tried repair and same issue. "ivalid node structure" redtating aftet that it just reboots and turns off a little bit after the chime. I have tried everything I could find on different forums without any success. I tried single user mode with the fsck commands and that failed also. I downloaded lion and made a recovery flash drive from another computer. I have since installed several new installations of lion after an erase and repartition. I took it to the apple store and they installed a fresh install of lion and it worked for a day then slowed down and froze. I would like to try everything possible before claiming the hardrive dead. I forgot to mention I have done PRAM resets in between the events I described as well as the SCM i think reset by unplugging. I have left it unplugged for over 12 hours, also have taken out all peripherals minus keyboard and mouse.

My friends Macbook would only boot to a blue screen. So I booted from system disk and checked the HD. Got this error;
invalid node structure
And now it's;
rebuilding catalogue b-tree
It's been like this for over 10 minutes - is that normal? Is there anything else I should do?

It won't start at all or it starts and works really slowly at first. Like the processor would work million times slower, almost like just hangs jammed. Sometimes after hours of trying to get it started, it will start and work normally again for a long time. But when I shut it off or put it to sleep, again it's nearly impossible to get it started again.
The Disk Utility said, that there's an hard drive error "invalid sibling link". I booted from the OS X installation CD and did the repair, but it said it couldn't repair it. Then I did this fix: [URL]. But again it said the same error. Then I booted normally and checked the Verify Disk again and to my suprise it is now saying the hard drive is OK. But it still has the same problem! It just is having really difficult time waking up.

I have a late 2006 iMac, which I know must be at the end of its life now, but at the weekend my main internal HD developed an error, and it wouldn't boot, even from the recovery partition.
I managed to find my old Snow Leapard disks and ran Disk Utility on my HD (when it actually saw it) and the error it came back with was "Invalid Node". After trying many things, I had to reformat and reinstall from my Time Machine back up, which went really well.
However, once all restored it tried to do a backup and it failed. I then went into Disk Utility again and it found the same error on the Time Machine drive.
Therefore, my question is, could the back up process have copied an 'error' to my back up? Or is this a fault somewhere else (Disk Management etc) that I need to watch in case it cases errors with my other drives that have important information on?

I have a 17inch intel iMac, early 2006 (the first release). A couple of days ago it decided it no longer wanted to boot up. Inserting the install DVD and running disk utilities verify/repair, it said that the volume had an invalid b-tree node size, and attempting to repair the volume failed.
Everything is backed up from this computer, so at this point in time I am only worried about getting it running again. So, I dug deeper to resolve the issue.

Since last night, every time i try to connect to [URL] on my macbook the message "invalid URL" comes up and i can't reach my profile.
I thought it may have something to do with my internet provider but it works fine on my ipad...
I have tried with firefox, chrome and safari and all 3 come up with the same invalid message except that the reference starting with #9.54e0fc ends differently...

When ever I use air drop I get an invalid Apple certificate. I then go and delete my Apple user name in Preferences/Users and then reestablish the same user name and password. Air Drop then works but once I close finder it will not work again unless I go through the same procedure. How can I keep the certificate valid permeantly?

I've had this 750 GB external drive for a year or two now, and have used it with no problems. All of a sudden, it can't be read by my MacBook. Finder can't see it. No applications can see it except Disk Utility. But DU can't repair it, and when I try verifying I just get "Verify volume failed: Invalid request." Also, when I'm using DU normally, I can't even eject the drive. But if I boot from my Mac disc, I can. But that's the only difference; still no repairing or verifying, and I get the same error message.

I have two retina MacBook Pros. Since getting them and trying to download software, I've downloaded multiple .DMGs with invalid checksums. Most recently, I downloaded the MacBook Pro (Mid 2012) Update multiple times from each computer using both Chrome and Safari and it took 8 tries before I got a valid copy (each had a totally different checksum). This has also happened when downloading Adobe CS5.5 and CS6 installers directly from Adobe's site.

Safari is constantly not accessing internet pages. It can somehow always load the apple.com site, but repeatedly it will lose google, gmail, yahoo, pretty much any other mainstream website. other times it will get to the page and not load images. just little boxes with question marks. and the thing is, 2 second before it did both of these issues just fine

Running OSX 10.5 and I encounter this problem on a frequent basis. The symptoms are the beach ball when coming out of sleep. I run onyx and find an invalid volume directory. Running first aid from the boot cd fixes it but it always comes back within a few days.

i'm trying to setup isight to take pictures whenever there is an invalid login.
i've searched around and there seemed to be a pretty decent guide from a year ago but the authsight program link is dead.
i've looked into other programs like ialertu but i'm looking for a program that will take a picture(s) at invalid logins and email them to me. ialertu just attracts attention with the alarm noise and i've had trouble with receiving the picture in my email.

I was just finishing writing an assignment for school. I always save while writing. Well after I was finished I saved and wanted to save as .doc. I pressed "save as" and suddenly pages did not respond. I tried to force quit but it wouldn't do that so I restarted. I thought since I already had saved it it would be okay, buy when I try to open it now I get the message "Document cannot be read, invalid file."

I have 3 occurrencces of the same NAS one of which works perfectly, How do I remove the other 2? I have tried previous posted solutions but they keep on returning - I guess because the IP Address is valid and the device active. There must be a system file I can edit??

I have gone through the setup of my newly installed lion server software. I setup a server.example.private host name and have turned on file sharing, and VPN. I bought the server software so I can access my host computer from my IPad and a windows based laptop. When I attempt to setup the profile manager I get to the screen in the directory admin setup that asks for the host name and password, etc. The name and host name are already populated with a generic names and the password fields are blank. Whether I leave the generic fields blank and try and enter a new password or change the generic fields and password to something new I get the same error message every time. It says "Computers host name is invalid. The host name does not resolve to any configured address on this comp. ensure the host name is correct. How do I find out what the correct host name is for my computer?
