Invalid node structure macbook 10.6.8

Im new to Macs and have absolutely no clue what to do im not worried about losing anything on it i just don't know how to fix and i don't have the disks i bought it used

You are going to need to get the disks, as the 'invalid node structure' error means you need to erase your hard drive and reinstall everything. Try talking to the person you purchased it from (they should have given the disk to you with the computer) but if you can't get it from them, contact Apple, they should be able to get you a copy of the original disks. There may be a small charge. If you can't get copies of the original disks, you will want to get a Snow Leopard install DVD which Apple sells through the online store - http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
Best of luck.

Macbook Leopard 10.5 is not booting up and not even getting Verified Error : Invalid Node Structure

Hey, I am using Macbook Leopard 10.5, Yesterday while i was working it was on low battery i thought to connect it later, but all of a suddent its stopped fucntioning and everything goes blank. I thought it might be a Battery problem, but even after connecting charger for 2-3 hours, its not booting up. Only the Apple screen comes and then it goes shut down automatically.
I even tried to fix it using Apple CD, Disk utility, When i tried to Verify the disk It shows following error :
Disk cannot be repaired or verify.
And details : Invalid Node structure
Volume needs to be repaired error : Filesystem verify or repair failed.
I have very important Data on this disk, so i cannot even erase it.
Suggest me somehting. It have enough space to install new OS but System shows you need erase it.
I have tried to use Apple Hardware test by Holding D key, But its not working.

Huge problems with my MacBook: Invalid Node Structure and More!

A couple days ago I was browsing the internet, and when I closed Safari, the system froze. I couldn't even force quit out of anything, so I had to shut it off manually. When I tried to turn my computer back on the next day, I couldn't get past the Apple screen. The little wheel would keep spinning, but I could never get anywhere.
Then, I tried to boot from the Leopard DVD to possibly reinstall Leopard, hoping it would work. At first, no drives would show up to install to, but for some reason, they eventually showed up. Problem is, I don't have enough free memory to reinstall Leopard. Furthermore, I've tried to fit it on the space I have, and it says that the install failed, so I can't reinstall Leopard.
I also went to Disk Utility from the DVD and tried to repair the disk. The only option available was to Verify Disk, but when I go there, that fails, and it says "invalid node structure."
I'm not sure what happened to my computer because it seemed to come from nowhere. To sum up, I cannot log in to OS X, or even XP on a separate partition, I can't reinstall Leopard, and I can't repair the disk. I've read about how DiskWarrior might help, but I can't get in to OS X. Does anyone have any idea what happened or what I can do? I haven't backed anything up, so if I'm screwed, then so be it, I guess. Just wondering if anyone has any explanations or suggestions. Thanks.

Interesting how many people have this same issue. A friend of mine has brought me her white Macbook Intel Core 2 with Leopard and it had a folder with a question mark instead of the apple at startup. I was able to boot using the Mac Install DVD and ran Disk Utility. It said something like "Invalid Node Structure" and "Cannot Repair". Unfortunately DiskWarrior will not fix this. I tried it to no avail. I'm resigned to the fact that a new hard drive is necessary.
The HD in there is a Hitachi 120GB.
It also wouldn't let me erase the disk nor partition it. Then, one morning I woke up and it was able to erase! So I erased, then installed Tiger. It seemed to be working fine. So I rebooted from the Leopard drop-in disk and installed Leopard. Then I restarted, and BAM! back to the question mark folder. Now I'm back to where I started. Other threads
I forgot to mention that my friend had photos and music on the HD that she couldn't do without and I was able to recover that data using Data Recover II. First I had to use SuperDuper to clone my own computer onto an external drive so I could use it as a boot drive.
For now the only solution is to buy a new internal hard drive and reinstall the OS. And regularly backup!!
So I guess this issue has not really been solved, but hopefully you have warranty. Unfortunately for my friend, this happened a week after her warranty expired.
Good luck.

MacBook pro stuck on start up, invalid node structure, diskos 1/0 error....

Hello.
After downloading steam and a few games my laptop froze, I tried starting it up but it goes no further than the blue start up screen.
I looked at some forms and used '/sbin/fsck -fy' to resolve the problem, but it says invalid node structure, diskos2 1/0 error... I don't hear and unusuial sounds coming from the harddrive. Other people simply replace their hard drives but I need to retrieve some recent important files that I had not backed up,        Is there any possible way of getting back my files or even fixing this problem ? Help please !

You have two options:
Buy Alsoft's Disk Warrior that will repair the problem.
Reformat the hard drive.
Option 1 costs $100.00. Option 2 requires having a current backup you can restore, erasing the hard drive, then reinstalling OS X, and restoring your data from your backup. If you choose Option 2:
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Invalid node structure

I have a Hitachi 500GB Go usb disk and its throwing Invalid node structure errors. I tried ripping an image from this disk, after about an hour or so of data copied (approx 100GB in the dmg) it will just close out and delete the .dmg, no errors, no nothing!
Disk warrior and Disk Utility fail to repair the disk/directory.
What's next for low-level access to this disk without having to buy expensive recovery software?
Also, it happens on both mine and my client's MacBook Pros'

Self-resolved:
Fixed by booting into bootcamp Windows 7 (ironic right?) It seems to ignore this HFS error...
Just so you know, the Windows app Recuva + Bootcamp will in fact give you a last-ditch chance to recover your data from a corrupted HFS disk like this one.

I got the dreaded "Invalid Node Structure" Error

Hi All,
I entered the Mac world recently with a spanking new Macbook Pro 15". Updated it online to the latest OS 10.6.4 Snow Leopard.
Today I was trying to install some more free application from the Official Mac Software Site. After installing a couple of softwares, I popped in the included recovery Disk and tryed installing xcode from the 'additional software' folder on the disk. But this failed
After this I thought of restarting the mac and try again. However, the **** thing now wouldn't boot anymore. Just stays on the Gray apple screen with the small ring rotating below it for ever.
Then I tried repairing it using the Disk Utility booting form the DVD. On verify Disk, it shows 'Invalid Node Structure'. So I clicked 'Repair Disk', And it just stayed there for ever without any progress. So I stopped it. And after trying the above 3-4 times, I Hard rebooted the system, and this time entered the console mode (Command + s).
Entered the command fsck_hfs -rf /dev/disk0s2 (disk0s2 is what Disk Utility showed me).
The output of this command shows:
** /dev/rdisk0s2
Executing fsck_hfs (version diskdev_cmds-491.0.2~7).
** Checking Journaled HFS Plus Volume
** Checking extents overflow file
** Checking catalog file
** Rebuilding catalog B-tree
disk0s2: I/O error.
disk0s2: I/O error.
disk0s2: I/O error.
disk0s2: I/O error.
disk0s2: I/O error.
disk0s2: I/O error.
disk0s2: I/O error.
disk0s2: I/O error.
disk0s2: I/O error.
disk0s2: I/O error.
And this goes on and on and on.... :((
Now what to do???

Hmmm, yeah that could be the last option, but I can't format the disk right now, 'cause I've some extremely important (not-yet-backed-up) files in it
So I'd like to try out all possible ways to recover the system before even thinking of a format!
BTW, the above fsck_hfs command I ran was by booting from the DVD itself.

Invalid node structure and Boot Camp 1.1.2

I downloaded Boot Camp 1.1.2 and during the installation of Mac Drivers I kept getting dialog boxes that the software i'm installing did not pass Windows Logo testing- I just ignored it.
After that Windows XP didn't recognise my keyboard, airport, ...
I prepared a new instalation with Boot Camp Assistant and i had an error message when the disk partition was processing.
I run Disk Utility from my Mac OS X install disk DVD and I got the following:
Verifying volume “Macintosh HD”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid node structure
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
Please give me some help to repair my disk and to understand what happened.
MacBook Pro 2 GHz Mac OS X (10.4.8)

If you are unable to repair the drive you will need to repartition and reformat the drive.
I recommend a cloned backup to an external FW drive. You can use this procedure:
How to Clone Using Restore Option of Disk Utility
1. Select the destination drive on the Desktop and press COMMAND-I to open the Get Info window. At the bottom in the Ownership and Permissions section be sure the box labeled "Ignore Permissions on this Volume" is unchecked. Set Ownership and Permissions as follows: Owner=system with read/write; Group=admin with read/write; Other with read-only.
2. Open Disk Utility from the Utilities folder.
3. Select the backup or destination volume from the left side list.
4. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button.
5. Click on the Restore tab in the DU main window.
6. Select the backup or destination volume from the left side list and drag it to the Destination entry field.
7. Select the startup or source volume from the left side list and drag it to the Source entry field.
8. Double-check you got it right, then click on the Restore button.
For added precaution you can boot into safe mode before doing the clone.
You will only have to reinstall your third-party applications. All standard OS X applications will be reinstalled except for bundled applications such as iMovie, iDVD, Garageband, etc. These can be reinstalled using the Bundled Applications installer on the OS X Installer Disc.
If you make a cloned backup all your data will be on the backup. You can restore it afterwards by copying the folders to their respective locations on the startup volume.

Invalid node structure. Free solution!

Invalid node structure. Free solution! Jan 2007.
Disk problem on an Intel Core Duo Macbook with 1.25 gig RAM and updated to OS X Tiger 10.4.8
Background.
About a month ago I ran into a problem with expose behaving oddly and after posting a question on this forum, the very helpful Dr Smoke advised me to clear my caches and to run 'repair disk.' from the installation CD. (This because I reported that a couple of times I had to do a hard reset.) I got expose fixed but discovered that my disk had serious errors in the directory structure, reported as "invalid node structure," and which Disk Utility could not repair. The laptop was running perfectly but several people posted advice that I should not leave this problem unattended to. Reporting this crisis again on the forum I was advised to buy Disk Warrior for a whopping $100 for what might be a once in a lifetime problem -or else I should back up my data and re-install everything. And I thought the Mac was more stable!! Up to 6 months ago I was a Windows user who often had such problems with the FAT but I was always able to cure them with Checkdisk or Scandisk. In fact MS Windows repaired it automatically after a hard reset. I feel that it is most unfair for Apple to not provide an effective utility to correct this kind of disk corruption. They bundle wonderful programs like iPhoto and iWeb but leave you in the lurch with a fundamental disk problem. With help again from Dr Smoke, I made my firewire disk bootable for Intel Macbooks (must be partitioned with the "GUID" option selected) and searched the forums for a way to get going again without forking out $100. I wouldn't mind if it was a program that did other useful jobs like on-the-fly partitioning but it was going to be an overkill for me. Learning a little from each of several other posts (sorry I didn't record the links) I put together the following solution which is easy to execute and the time consuming elements can be left to run at night or when away from the computer. You may see possible short cuts as you read through to make it even simpler, but here is my full story! Actually I was travelling around Eastern Europe and couldn't easily get disk Warrior or Tech Tools sent to me. I needed to find a solution from reading advice and downloading disk utilities off the Web.
I have a 40 gig ext. disk, mounted in a "hotdrive" enclosure which is useable either as firewire or USB 2. http://www.byteccusa.com.
My Bacbook disk is 60 gig but only 25 gig was in use.
My Macbook was up todate with every part of OS X including the firmware. except for Garage band which I do not use.
Step 1a. I downloaded 2 free disk cloning programs - Carbon Copy Clone and SuperDuper. I preferred the latter. Step 1b I read about Migration Assistant - part of OS X Tiger.
Step 2. I partitioned the Firewire disk in two (32 and 8 gig) for future convenience, and zeroed the disk after Dr Smoke's advice.
Step 3. I installed the basic OS X package onto my 8 gig "Firewire 2" using only Install (DVD) disk 1 which takes up less than 5 gig. (In Setup one chooses to not install the additional programs - iPhoto etc.) I checked that I could boot from it and that it was healthy by running "verify disk" when booted from the internal hdd.
Step 4. While booted from my internal HD, I cloned Firewire 2 onto Firewire 1 (32 gig) I verified the disk (no problems) then booted from it and assured myself that I had a fully working copy of OS X.
Step 5. I booted from firewire 1 and used Migration Assistant to import EVERYTHING - files, programs, the lot, from my internal HDD with the node structure problem. My firewire disk was now 25 gig the same as my internal HD. It had now two users, both shown as administrators. I booted to my newly-imported user ID - the original one that was on my internal HDD. The only problem reported by Migration Assistant was that Missing Synch for Palm might need to be re-installed which would not be surprising given what it does. Later when all was done, I discovered that the migrated programs had been placed in a folder on my desktop so I opened it and moved them all into the 'normal' Applications folder created by my new basic install. (Some programs don't like running from anywhere other than the Applications folder.)
Step 6. I worked from Firewire disk 1 for a day, trying out every program and it was working normally. One thing I noticed was that iTunes seemed to import as the original tiger 10.4.6 version so I needed to install the update to 7.02 which I had kept in my download folder. I tried to install the OS X update to 10.4.8 but a dialog informed me that I could not do that on this (external) disk. I don't know why, but later on I updated to 10.4.8 overnight using Mac Update.
Step 7. Make sure all your data has been backed up somewhere, and that there is nothing of value on your internal disk. Take a deep breath, and wipe it!! I did this using Disk Utility (from Firewire 1) and took the chance to partition my HD into 32, 18 and 6 gig. I chose GUID partitioning and zeroed the disk. No going back!
Step 8. I booted into Firewire 2 and installed SuperDuper. Then, from Firewire 2, I cloned Firewire 1 onto my internal HD 1 partition of 32 gig. SuperDuper does not call it cloning but rather 'copying all files.' It booted and works fine (as of Jan 10). Then I verified the disk when booted from one of the firewire partitions and all was well. Phew!
I ran sofware Update and it offered to update Java, OS X for Intel, Garageband and Quicktime.
So my node structure is cured and my internal hdd is partitioned without spending a penny and without having to re-install my programs one by one.
Note: There may be a few things to re-install or some prefs to reset but in general this method worked well. I mentioned having ro re-update iTunes.I also had to reset the Quicksilver prefs, and maybe I will yet come across something needing to tweaked again. (QS is a free launcher.) Oh yes, FireFox did not run well so I re-installed it.
I share this in appreciation for the help of Dr Smoke and others who answered my questions and for those whose posts were helpful to read, and for the benefit of others who may find them selves in the same predicament as me. And, oh yes, the trouble was not enough to cause me to go back to that other OS! Louis J

Invalid Node Structure is not a hardware failure, it never was (you may still have a hardware failure, but the Invalid Node error is not indicative of this problem.
Still, Disk utility will certainly fail to fix it, and DiskWarrior will probably fail too.
But don't despair. Try this, and don't give up till you've tried it at least three times.
First, get the name of the partition of the failing volume.   You can get it most easily by finding your disk in Disk Utility, selecting your partition (not the drive) and type cmd-i.    Look for "Disk Identifier" right at the top.
Then, open up Terminal, and type this:
sudo /sbin/fsck_hfs -yprd /dev/disk5s2
substituting your disk identifier for the one already here.   Keep the "/dev/" part.   Enter your password, and wait. It may take a while. I have had this fail several times before finally working so its important to keep trying.   It's faster than a reformat!!!
If the afflicted disk is your startup disk, you will need to do this in recovery mode: restart the computer, hold down option, and wait for the disk options to appear.   Select that, then proceed to Disk Utility and then Terminal as described above.
Good luck, and always keep a backup!

Invalid Node Structure on SSD

so i got a vertex 2, 120gb ssd drive a couple of weeks ago, but suddenly my computer crashes hard, my cpu turns out 89c (about 180F) in temp and "quickload D" uses up most of the cpu power. i force quit everything and DMG files just get some error i cant remember now. so i try restart right. but i just get the apple logo and some gray bar at the bottom that goes maybe 10% of the way and then it just shuts off. tried to boot a couple of times but nothing.
so then i boot from the snow leopard disc and run diskutl. and find "Invalid Node Structure" thats not reparable when verifying the disk. so now i have to reinstall. because i haven't come around to getting a system backup yet.
this goes without a hitch and the macbook is just fine now. no invalid node when running verification.
after scouring through OCZs forums i find this to be a reoccurring theme, but mostly on the vertex(1), and that not letting the computer go into hibernation will/might solve this.
so my long winded question is this. anybody else have this happen to them? have you fixed it? and what kind of SSD do you have?

Is your computer still under warranty? If so you might want to bring it to a genius bar. http://www.apple.com/retail/geniusbar/

Invalid Node Structure error

Hi All,
I need some information on how I might solve a problem. I ran my Disk Utility earlier today to verify the HD on my MacBook Pro because my computer just seemed a bit off. It froze the other night when I shut it down.
Here is the message I received:
Verifying volume "Macintosh HD"
Checking HFS Plus volume
Checking Extents Overflow file
Checking Catalog file
Invalid node structure
The volume Macintosh HD needs to be repaired
ERROR: The underlying task reported failure on exit
1HFS volume checked
Volume needs repair
I booted the computer from the original OS X Install Disc and tried to repair the hard drive, which didn't work. That's when I started reading the Tiger Forum. I have since discovered that this error cannot be repaired from the Install Disc and probably will require an erase and re-install. However, I did read about a 'fsck' command.
I would like to give this a try, but am not at all comfortable with running commands. Would someone be willing to walk me through this and/or offer any other suggestion for fixing this?
Thanks

Michelle,
Sounds like you are really learning a lot in a hurry. That's good. I can't tell you how long it will be before your system "acts up." I would take this opportunity to backup any really important data to DVD/CDs while you are in the process of getting an external drive and Disk Warrior.
Good question about whether your file system error will be copied to you external drive when you clone with SuperDuper or Carbon Copy Cloner. I don't know exactly but it will certainly be better to have a backup that may be slightly imperfect than to have no backup at all. Of course, after you fix the error on your internal drive with Disk Warrior, then you will reclone your repaired system to your external.
Regards,
Steve M.

Dreaded "invalid node structure" dealie

The MB had been running slowly and a lot of applications (particularly web browser) were having a hard time shutting down. I was occasionally required to do a hard restart. That being the case, I ran DU and got the "Invalid node structure" alert, saying the drive could not be repaired. I took it to a "genius" at the local Apple store and he said that such an error is due to a software issue and, as such, not repairable under warranty. "You have to get Disk Warrior or Tech Tool. That should fix it."
Well, I shelled out $100 for DW4 (which I know I should have, anyway) and it didn't fix anything. It said the directory couldn't be replaced due to disk malfunction (or somesuch). So, I figured it must be a bad HD, potentially. I even arranged for a take-in repair.
Well, today I decided to run an fsck in single-user mode, just to see what I could see. It, too showd the invalid node structure, as well as B-tree. It also stalled at the end. I thought, "OK, now I really did it." After a hard reboot, I ran DU again to verify disk. This time, it came up with no errors found, disk does not rquire repair, disk verified, etc.
I guess the question after all that - think I'm in the clear? What could the problem have been?
macbook 1.8GHz - PB G3 (Lombard) 333mHz Mac OS X (10.4.9)
macbook 1.8G - PB G3 (Lombard) 333mHz Mac OS X (10.4.9)

Thanks for the response.
When I got home from work, I ran DW. Unlike prevous attempts, it was able to rebuild and replace the directory. Re-ran Disk Utility once again, to be sure, and it came up as all good. Also, both DW and DU gave an A-OK to S.M.A.R.T. status.
After rebuilding the directory, everything's running much faster and I no longer have to force quit all the time. Seems to be doing its thing.
Fingers crossed ...

Invalid Node structure/ computer running slow?

Hi everyone,
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 never backed up (I know, I know..) so needless to say I'm a little stressed.
Thanks!

That does sound stressful. Sorry to hear you have had these problems.
The good news is that you can probably get your data back. Follow the steps in this document to remove the hard drive from your MacBook. Put the hard drive in an enclosure - you can get these for about $10-15. Connect the hard drive to another Mac and see if it shows up on the desktop. If it does, extract the data.
After that, take the whole thing in to a shop to have them see if they can correct the liquid damage. This may or may not work.
Best of luck.

Invalid Node Structure, Mac Not Starting

*THE PROBLEM*
My MacBook does not start. All I see when I press the power button is a gray screen with an apple logo and a spinning wheel.
*WHAT CAUSED THE PROBLEM*
I changed the input languages settings in international in system preferences to “Devnagari-QWERTY”. Then I typed my name in 'Devnagari' in Textedit and copied it. I created a new folder on desktop and pasted my name copied earlier. It worked. So I went ahead and tried renaming my startup disk (Macintosh Disk) in the same manner. I clicked on its icon, hit enter and command+v. Immediately my mac froze. Noting happened. Even commandoptionesc did not work. After a long time I pressed the power button for 5 sec and tried a restart. Now it won't start.
*SOLUTIONS I TRIED*
1. *Safe Boot (shift while startup):* No result, all I get is a gray screen, an apple logo and a spinning wheel appears after a minute and its stuck there.
2. *Tried Single User mode (command+s):* Computer does not start and is stuck with the following text.
Probe booting in single user .. do not match
disk0s2: 0xe003005 (UNDEFINED)
Load of /sbin/launchd, errno 85, trying /sbin/mach_init
disk0s2: 0xe003005 (UNDEFINED)
Load of /sbin/launchd failed, errno 85
3. *Tried Verbose mode (command+v):* Computer does not start and is stuck with the following text.
disk0s2: 0xe003005 (UNDEFINED)
Load of /sbin/launchd, errno 85, trying /sbin/mach_init
disk0s2: 0xe003005 (UNDEFINED)
Load of /sbin/launchd failed, errno 85
4. *Disk Utility from OS X Install disk:* Tried using repair disk. But it does not work either. All it says is
Verify and Repair disk “Macintosh Disk”
Checking HFS Plus Volume
Checking Extents Overflow file
Checking Catalog file
“Invalid Node structure”
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.
*5. Reinstalling OS X from install disk:* I tried this as a final resort.
a) The normal install did not work because my startup disk had OS X 10.4.11 and my install disk had 10.4.6, so it gave an error that I have a “newer version installed”.
b) I can not do an archive and install because I have only 4 GB free space and it requires at least 15GB.
c) I do not want to do erase and install because I do not want to loose my data.
*MY MACBOOK*
1. I have a first generation MacBook, Intel Core Duo 1.83 with 512 MB Ram and 60 GB HDD with Mac OS X 10.4.11.
2. S.M.A.R.T status of the disk is verified
3. I can browse my files on the disk if I click on new disk image in Disk Utility from Install Disk.
4. There is no problem in mounting the disk.
LIMITATIONS
1. I am not at my university so I do not have any other external HDD or any other Mac for a “Target Disk Mode” for data backup.
2. All I have is my Mac and 10.4.6 install disk.
3. No broadband so can not download large files.
4. I can not loose my data.
Is there any way of fixing the Mac, given the limitations given above. Something using command line, or anything that will make it work again. How do I fix the invalid node structure. I really do not want to loose my data and I am in transit so I really need my Mac to work.
Any help would be appreciated.

Ambarish:
The article Disk Utility reports "Underlying task reported failure" when repairing a volume gives more information about the issue you are experiencing. The reference in the article to a third party utility is the utility referenced by BGreg, Disk Warrior.

Problem when booting - Invalid Node Structure

Hey!
I decided to put my MacBook G4 up to date. So I installed several updates of my software. So far so good. Then I tried to check with Disk Utility wether there were any problems on the file system. I ran "repair Disk Permissions" and some errors where found and corrected. I tried "Verify Disk" and it announced there where some errors namely "Invalid Node Structure". As I couldn't repair the disk as it was the current boot disk I decided to run Disk Utility from a CD. Unfortunately I didn't have my original cd so I asked a friend to use his. He gave me his "MacBook Pro - Mac OS X Install Disc"s (Mac OS X 10.5) and I ran it on my PowerBook G4 (Mac OS X 10.4 installed). It gave the same result like when I ran it from my hard drive. When I tried to repair it, it started and stopped after some seconds (between 20 and 40 seconds) saying it was unable to repair it.
After that the computer does not mount from hard drive (10.4 installed) anymore, only from cd. I tried booting in single user mode and executing /sbin/fsck -fy but I had the same result ("disk0s10: I/O error. Invalid node structure (4, 7698) **Volume check failed.").
I think I can resolve the problem by starting my mac in firewire mode, backing up my data and reinstalling Mac OS X (would a repair from 10.4 Disk Utility work?) but I would be happy if there were any faster / more elegant way to do so as I cant use my install cds for 10.4 right now as I am in an other country for some time.
Any help?

Hi Ja!, and a warm welcome to the forums!
Unfortunately DU & fsck can't fix all that much, your best bet is DiskWarrior, you need the CD though.

If DW can't fix it, you might try Data Rescue II...
http://www.prosofteng.com/products/data_rescue.php
(Has a Free Demo to see if it could or not, but you'll need another drive to recover to).
Or FileSalvage...

to recover what you can.
PS. Don't use Leopard Install Disk to work on Tiger Hard disks, it's always messed up my Tiger Disks ehen I did.
Also, not a good idea to even Repair Permissions if there are Disk problems like you have, you don't want to write anything to a disk that has problems, that means even trying to boot off it until you fix it.
