Hardware :: WD Essentials 1TB Hdd - Invalid Node Structure - Need To Format (HOW)
Dec 31, 2009
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?

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.

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?

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 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.

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?

Alright, so far I have tried an Upgrade and an A&I and it still fails with that message. I don't know what to do. I have an unusable computer, and the install keeps failing.

My old 120GB hard drive seemed to be flaky, and I needed the increased capacity, so I upgraded to a 500GB hard drive on my white MacBook. Install was not hard at all, I formatted and partitioned the drive, but I can't seem to install MacOS X (10.5) on it from the DVD's that came with my MacBook. It will boot to the installer DVD, allow me to select the hard drive, and starts the install. However, each time it ends with something along the lines of "Error verifying Essentials package", and advises me to contact the software manufacturer. (Strange that it advises contacting the "software manufacturer" rather than "Apple."). The DVD is pristine, no evidence scratches. I also had problems earlier performing an Archive & Install on the old drive, but I thought this was because it ran out of room. I can also boot the MacBook through my old drive, attached to a USB enclosure. Can that drive be used to install a new system?

I just purchased a new Samsung HM640JI hard drive to replace my old 250gb fujitsu hd. The problem is, if I put the new samsung hdd inside and try to do a clean install of snow leopard, the setup always hangs at "extracting essentials" and I have to keep the shutdown button pressed to close my laptop. I thought I have a ram problem or that my dvd is busted but that's not the case because I inserted the samsung hdd in an enclosure, connected it via usb and the install went just fine. After the setup was over I rebooted a couple of times (still in usb enclosure) and everything was fine but after I inserted it in my mac everything went to hell: excruciating slow boot and runtime. I repeated the process twice to be sure. My mac is a 15" 2.53 core2duo 9400m

The setup: VirtualBox (latest), Snow Leopard and Windows XP.
The situation: I installed VirtualBox, all seems fine. I then installed Windows XP. All seemed fine. I installed Gust Additions. Then I installed Safari. Then I went and downloaded and installed Microsoft Security Essentials. When it attempted to install, it would fail, and asks me to restart and try again. I went ahead and restarted. When the virtual machine restarted, it'd get all screwed up, squashed video and frozen. Then I'd get a dialog saying that the virtual machine disk image has a problem or some such, and claims that a likely cause is a problem with the harddrive. After I clicked OK, it beachball'd. I force-quit the program.

Everytime I try to convert old Quicken data files so I can use the new Quickens Essentials I get the message: "There was an error installing and launching the Quicken File Exchange Utility." So I can't launch Quicken Essentials until I can convert the old data.

I turned off my connection sharing (bridge mode).
I was wondering, since the Airport is no longer a node on the internet, why does the configuration still allow me to enter TCP/IP information, and does it make a difference what I put in there?

This is my first post, I hope I am sending it to the right place. I want to use a new mac mini (not yet purchased) as a compute node to run day and night on some modeling code. I don't want to connect a keyboard or monitor - but I have access to these to set things up. The model accesses data on the internet, and I want to connect (wired or wireless) to my cable modem to get at these. Once set up and running I just need ssh access to see how things are going and scp to copy stuff onto and off of the mini. I have a MacBook that I plan to use for this purpose, that I want to connect wirelessly to the mini. Is this possible? Is it difficult? I don't really want to shell out for expensive remote desktop software when I only need terminal type access to the mini - to check on progress, copy stuff on/off and compile programs.

I have two disks containing data organized in a RAID 0 array. I have a MacPro running Snow Leopard. Recently, the RAID array does not show up in the Finder and is not accessible. Disk Utilities can't inspect or repair the disks because of the dreaded B tree node size error.
Can these disks be salvaged? Can the data be recovered?

I set up a RAID using 4 Segate 320GB SATA drives in it's own box. It is connected to my G5 (OS 10.4.1) via a Highpoint RocketRaid 2210 card. After 2 months, I have gotten the b-node tree error twice. The drive fails to mount and drive utilities (including Drive Genius, DiskWarriror) can't fix it. I was able to use Drive Rescue 2 to get the info off of it, but I am concerned as to why this keeps happening. I can reinitialize the drive and get it working again, but this is not a solution.

Starting out on iPhoto 09. At the moment all my photos are organised in folders, eg Holiday July 08, New year 07, Childs 4th B_day, Funfair March 05 etc I would like to keep them in this order if possible, and start using iPhoto to tag, and organise them all. Reason I want them still in folders is that I also have a Windows PC, Xbox 360, and want to be able to sort them on here to, which wont have iPhoto's organisation and so need the folder structure.

I just got my new 24" iMac, and within a few days I'll be making the switch. After reading countless forum messages and tutorials, I'm still a bit unclear about file structure (PC) vs folder structure (Mac).
I know the finder will show me folders and sub folders, which seems similar to an explorer file structure. However, I'm not sure how I'd set some things up.
For example: On my PC I have a folder for MY FILES and under it I have folders such as Photos (with sub folders) and Documents (with sub folders). I also have a folder for my pet photography business, which is called NYPetShots. Under that I have a folder for the Pet Photos (with sub folders for shoots etc.), another one for my Promotional Materials (which includes jpgs of flyers and postcards), another for Non-Photos (which includes documents and correspondence), and another for Web Stuff (which includes my web back-ups and Photos used for the web - also in some sub folders).
I am not wedded to using the exact same structure. However, it would certainly make sense to me to keep it. What would it look like on the Mac? I will be importing my entire Lightroom Catalog into the Pictures folder, and that will include my business photos as well as my personal photos. However, they will keep logical structures and will have keywords. I assume there is a folder for documents; however, I have both personal and business, with sub categories in each. So, could I continue to use a folder just for my pet business, even though it consists of different types of files?

my iMac has been running strong for about 9 months now. The only gripe i have had is that is has begun to get SLOW booting up and mundane tasks such as opening apps. iTunes takes a good minute to get up and going. I never even noticed the slowness until i got a MacBook with much worse specs that blew it away.
So I decided to run TechTool Deluxe and see what happened. My iMac did great until the Volume Structure. I repaired it a good five times. The last two times it couldn't find anything to fix and it is still failing!
I don't want to have to buy DiscWarrior (i think thats right), or reformat my drive, mainly because i haven't the foggiest on how to do that. Any options available to me besides these? And do you think the slowness is more due to a growing amount of files, or maybe even a *virus* *gasp*, or to the failing structure?

I am trying to move my itunes data over to a new mac. So I moved the iTunes media folder to the new mac, but none of the mobile applications are (which are placed in the mobile applications directory in the itunes media directory) are displayed in iTunes on my new mac. I already changed the iTunes media folder in the preferences. What I managed to do is transfer all purchased items from my iPhone in iTunes, but now each iOS app appears 2 times in the mobile application folder. The next problem is that if i now what to sync my iPhone on the new mac iTunes completely messes up my app folder structure on the iPhone but I would like to keep my structure. How can I move copy ALL of my iTunes data from the old to the new mac correctly?? I don't know why apple made it so hard to do such a thing.
