Invalid b-tree node and the disk can't be repaired. Is it worth the reformat or is the hard drive trashed? This is a Mac mini, I've had it since 2010 and already had to replace the hard drive once.
Swapped out the monitor on my Mac mini tonight and it wouldn't start back up. Managed to boot off the install disk and run disk utility, which gave the invalid b tree node error. Wasn't able to repair the disk, suggested a reformat. Is this worth my time? Or is the disk toasted? I got it in 2010, it's out of warranty and has already had the hard drive replaced once. Thanks!

If you want to save the data from the drive, Phoenix might be able to copy (clone) it off on another volume. You can check it out at:
http://scsc-online.com/Phoenix.html
Phoenix does a file copying cloning, not block copy cloning, so a new index is generated on the drive when the copy is being made. If none of the files got lost, meaning just the index is screwed up, I would think this would work.
Regarding the hard drive an index problem isn't a hard drive problem. That hard drive may be in perfect working order, especially since it's fairly new.

Receiving Invalid B-tree node size in Disk Utility
My mac mini has recently bit the dust. I did a hard shut down by holding down the power button. Since then I have not been able to bring it back. It started with a folder with a ? in it. Sometimes it sits at the apple logo, and other times it goes to a gray screen and just reboots eventually. I am running Snow Leopard, and I have booted from the install cd. I have tried running Repair Disk in Disk Utility, but I receive the following error: "Invalid node structure Invalid B-tree node size The volume could not be verified completely. Volume repair complete. Updating boot support partitions for the volume as required. Error: Disk Utility can't repair this disk...disk, and restore your backed-up files."
In the pop up window it says "Disk Utility stopped repairing "macintosh HD" Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files. On the left hand side of the window I see 60.01GB ST96812AS Media, and then I see Macintosh HD offset underneath. The Macintosh HD is in light gray and is not mounted. When I try to Mount it it gives me an error and tells me to repair the disk.
My question is do you think Disk Warrior would work or something like that software? I tried to do an Archive and Install, but since the HD won't mount I can't do an installation. Is my HD dead?
Any help would be appreciated!
Sincerely,
MattAs you can see, I received no help from this forum. I ended up replacing the hard drive after trying disk warrior unsuccessfully! I wish you luck and anyone else who has this issue.

ok so i accidentally remove the USB while my laptop was backing up to the time machine partition on my external HDD. I plug it in again, and no time machine partition. just the other part (fat 32 partition). so i open disk utilities.. the partition is there but grayed out. so I repair it.. and it says it cant repair it i need to back it up and format it. ok great.. i tried to do that and it said it can't access the disk.. super.
any way.. i don't know why i decided to check my other drives and see how they're doing.. and it turns out.. my startup disk has problems.. and you guessed it.. it can not be repaired:D so i restart in recovery mode.. did it again.. and? it can't be repaired.. i need to backup the drive and format it... (like the same problem with the time machine partition) just great! so i restart the laptop.. it safe boots.. I dnno why.. and everything is like it was.. I mean I don't see a problem with my drive.. i can do everything but that "cant repair" thing is scaring me.. what should I do? just leave it? or brace myself for a possible HDD death? I DON'T EVEN HAVE A BACKUP)
help me i feel vulnerableAs you have indicated, you don’t want to touch the partitions on your existing external drive because it has live files in the FAT32 partition for which there are no copies anywhere else. That leaves you with two sets of data that are currently not backed up: your FAT32 partition and your system drive. I suggest you need at least one more external HD for backups.
A “backup” drive should never have live files on it because should that drive fail all the live files on it would be lost. So you need a second external HD anyway for a proper backup scheme.
I would partition a new disk as you have the current one and then copy all the FAT32 files form the old disk to the new one. Then you can try repartitioning the old drive. I would then setup a backup scheme to periodically clone the new FAT32 drive onto the old FAT32 one, using the new disk for your live FAT32 files and dedicating the old disk to backups. You could also continue using the old disk for Time Machine backups.
You can use Mac cloning software such as Carbon Copy Cloner to maintain the cloned backup copy of your FAT32 data.

Invalid B-tree node and disk stuck
Last night my 2 year old iMac froze up. When I re-started I received the flashing question-mark folder. I ended up inserting my OS X install disk and attempting to run the Disk Utility. I tried to repair the disk, but got the "Invalid B-tree node size" error with "The volume needs to be repaired."
I have tried a lot of things and will probably end up buying Disk Warrior and hoping that fixes it. BUT, I have another problem. I can't eject the OS X install disk. The option to eject is greyed out on the Disk Utility, the eject key doesn't work, and I can't find any way to unload the disk. Help would be appreciated.If you have an external hard drive it would be easier to clone your system to the external then boot to the external and run Disk Warrior from there. However if your system won't boot in the first place that won't work. You could pick up a copy of Disk Warrior from the Apple store.

How can you repair "invalid node structure and invalid b-tree node size"
I have a MacBook Pro 17" and the original install disk is Mac OS 10.4. I have an update 10.6 install CD, but I cannot use it to boot up my computer. My computer had been running on 10.6 when the problem occurred.
It seems my harddrive has crashed. It only boots to apple logo and spins. I have reset the pram. Started up in safe mode with shift pressed down and started up on the start up disk, where I did repair disk and got this "invalid node structure invalid b-tree node size". Then it said repair failed to complete. I tried booting again but it still failed. I thought doing a restore might solve the problem. I have a month old backup with time machine which is on a lacie external drive, but when I try to restore using my original 10.4 install disk, I can only choose the lacie hardrive icon (by dragging) and cannot choose the folder in the backups with the latest backup. When I tried to restore, it says my source is not a valid option. Is this because it is a 10.4 startup disk.
Basically I have two questions: Is there a way to fix my problem without doing a restore and if I have to restore, how do I restore my time machine backup? Will I need to do a reinstall with 10.4 and then update to 10.6?
I really hope to find a way to have my computer back to how it was when it started spinning and if not, at least as it was when I did the latest backup 3 weeks ago.
Please help me!!!
RebeccaYou should be able to boot to the Snow Leopard upgrade disc — you had to do so to install the upgrade in the first place. If you can't boot to it now, either the disc is scratched or dirty or your drive's lens is dirty; for the latter problem, a drive cleaning disc is an inexpensive, frequently-used and often successful remedy, available at any store that sells DVDs.
Because you're running Snow Leopard now, you should repair your hard drive directory using the Snow Leopard version of Disk Utility, not the one on your Tiger installer disc. If you aren't able to do so even after trying to clean your drive, you could buy and use DiskWarrior to rebuiild the damaged HD directory. But DW costs nearly $100, and though it would probably do the trick, that's a bunch of money. You'll have to weigh its cost against the value of the new or changed data on your drive that hasn't been backed up in the last three weeks. If you can get along without that data, then erasing your hard drive and restoring from your last backup is the no-cost, immediate (as opposed to waiting for a DW startup disk to arrive in the mail) solution. -
I have an iMac mid 2010. After Disk utilities said the drive was corrupt, I ran the hardware test (extended) 3 times. No problems. I than ran Disk utility again and got 2 messages in red…keys out of order, and ……Volume corrupt, can't be repaired.
I tried to do a system install, but message said…disk can't be changed. Will a complete erase and install fix this ?
Everything is backed-up.There's hardware and software.
Your drive could physically be in good condition but something has caused the file structure to be messed up (it just happens sometimes). The directory that keep track of files is corrupt. Disk Utility can help determine if that is the issue. In some cases it can repair the problem but it cannot do it to a drive that is being used to boot the system while you are doing that. You have to boot from another drive. Some things DU cannot repair and you need to try a stronger utility such as Diskwarrior.
A failing hard drive (one with mechanical issues) can be a cause of file structure issues but this is by no means always the case. Apart from looking at the SMART diagnosis feature of Disk Utility (and smart isn't totally reliable) there often isn't a way to tell if a drive is failing until it suddenly happens, which is why you need to maintain backups.
In your situation it does sound serious and not just minor directory corruption. You can try erasing (formatting) the drive, You may need to do this if it is really corrupt, in which case there could be underlying physical issues. I use old technology but if you have the patience you can try erasing the drive with the security option of writing zeros once (don't do more unless you are going on a 3 week vacation). This makes the drive not simply assume everything is okay by forcing it try every part of the drive by writing data. If something is gong wrong you may find it marks a lot of bad sectors, or flat out refuses to format. Then you know you need a new drive. -
I have had IPhones since their inception. Last phone was the 5. A few months ago, I upgraded to the 6 Plus.
Here is my issue.
On my 5, my car radio (which has USB port) allowed me to plug in and listen to radio or music from my phone and the bonus was it charged the phone as well. All worked great.
Now with the 6 Plus, neither of things work. The message on the radio (Kenwood) says I Pod error. The message on my phone say's "this device is supported".
I have called on this before and was told you are aware and that the issue will be addressed in a future update. There have been several updates on IOS 8 and the issue remains.I have a Kenwood KDC-X695. When I purchased this stereo and had it installed, I had an ATT iPhone 4.
It worked with the stereo, but had a few issues. I had purchased a few audio books that I would listen to while driving. When I plugged it in it would immediately begin to play the book from the beginning or if I had been listening to music, it would start playing the song that was at the top of the song list.
The stereo came equipped with Firmware version 3.05. I upgraded to the iPhone 5 a year later. I had that phone for approximately 2 years. The song or book issue remained the same.
I just recently upgraded to the iPhone 6 and the Bluetooth function still works, however the USB port on the stereo that the phone plugs into to allow files on the phone to play through the stereo no longer works.
I contacted the service provider (Verizon) and after speaking to several different technical support technicians, they provided me the phone numbers for Kenwood and Apple because they were unable to help me.
I spoke with Kenwood technical support the following day and after a few fumbling miscues from the technical advisor, it was suggested that I upgrade the firmware, even though the Kenwood literature warns against this if the Bluetooth portion is working, because if there is a problem with the upgrade, it can render the Bluetooth useless and non-functional. The advisor did suggest the latest firmware on the second or third attempt, after I pointed out what I was able to glean from my initial search.
Later that day, I went back to the Kenwood site (from their homepage) and by using their selection tools, discovered that this particular model was only ever intended to be used with the iPhone 4S (the technical advisor was not aware of this, even though I mentioned this during my phone call earlier in the day). According to the Firmware selection tool, my iPhone 5 should not have worked with it.
I performed the Firmware upgrade, and it took 13 minutes. This was less than the 15 minutes that was forecast in the Kenwood literature. The Bluetooth still works but the USB cable connection still causes the unsupported device message that I received prior to the upgrade. I am incredibly annoyed and disappointed.
By upgrading to the iPhone 6, I have three choices; (1) only use the Bluetooth for phone calls without the ability to play other files from my iPhone 6 (2) forced obsolescence of my stereo, requires buying a new stereo (3) return my iPhone 6 and go back to my iPhone 5.
I do not believe that I should have to be a software/Firmware/hardware engineer, vetting every single device that I own; prior to upgrading a cell phone.
I am incredibly annoyed with Apple at the moment.
I have a separate Bluetooth headset that worked with both my iPhone 4 and iPhone 5 that the iPhone 6 simply does not recognize. That is another story for another time.
Currently, I am incredibly underwhelmed with Apple. -

This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in safe mode.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it:
for k in /Sy*/L*/Ex*/{,.?}*.kext; do test -f "$k/Contents/Info.plist" && /usr/libexec/PlistBuddy -c "Print :CFBundleIdentifier" "$_" | egrep -qv "apple|Accusys|ArcMSR|ATTO|CalDigit|HighPoint|hp-fax|JMicron|print|SoftRAID|stex" && echo $k; done | open -f -a TextEdit
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. Post the contents of that window, if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
sudo defaults read com.apple.loginwindow LoginHook | open -f -a TextEdit
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
Repeat with this line:
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null | open -f -a TextEdit
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 4
osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null | open -f -a TextEdit
Remember, Steps 1-4 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal. -

Is my hard drive dead? Invalid B-Tree Node Size
When I turn on my powerbook it goes to the grey screen with the apple in the middle comes up and then it goes to loading Mac OS X which I am trying to do but when it comes to Select a Destination my hard drive is not listed. I click on utilities and go to utilities and disk utility. My hard drive is listed on the left side so i click it. I then click verify disk and it sais Invalid B-Tree Node Size and Volume needs repair. Then I click repair but the same thing comes up. What can I do? PS-I did a search but none of the info I came up with helped me at all.
they are about $100 and available from most Apple dealers:
http://alsoft.com/DiskWarrior/index.html
http://www.micromat.com/
if there are no important files on the drive, erasing the drive and reinstalling OS could possibly fix it unless it's caused by failing drive hardware.
if erase/install does not work properly, could be bad drive.
"B-Tree" message could simply be caused by messed up files and there is nothing wrong with the drive itself. -
I am trying to log onto a Mac Mini I haven't used in awhile and I forgot the password. I am trying to reset the password with my apple ID but the computer keeps saying the Apple ID and the password are incorrect whenever I know they are, as I am using the exact same ID right now.
I have switched my password in the past, so my theory is my mac mini thinks that my password has not changed and it will not update because The Wi-Fi password has also changed so it cannot connect to any servers...Does that sound like I am on the right track?
Is there a way to update my Wi-Fi password (saved into the computer) without logging on?If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password.
Otherwise, boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar.
In the Terminal window, type this:
resetpassword
That's one word with no spaces. Then press return. A Reset Password window opens.
Select your boot volume if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
Select
▹ Restart
from the menu bar.
You should now be able to log in with the new password, but your Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as your login password), there's no way to recover it. -
I purchased a mac book pro in oct 2011, I restarted it after updating and it,s stuck on apple symbol, I hit command R while restarting and clicked on disk utility. It says disk can't be repaired, apple wants $249 to tell me what's wrong. Please help!
What Apple store told you they wanted $249.00 to tell what is wrong?
If this is a 13" Macbook Pro then that is the cost of the Extended Applecare warranty. As you are outside the 90 days of Free Phone Support then what Apple told you is that to get Phone Support you would either need to pay $45 per phone call or pay $249.00 for the Applecare extended warranty which comes with 3 years Free Phone Support from date of purchase.
Or you can take it to a Apple Genius Bar and have them look at it for Free.
Every Mac comes with 1 year warranty and includes only 90 days of phone support. You can buy the extended Applecare warranty anytime within the first year of ownership, IE until the 1 year warranty runs out.
I suggest you have your computer looked at by either an Apple Authorized Repair Center or Genius Bar and then before the 1 year warranty runs out buying the extended warranty -
My Macintosh HD partition is damaged and the disk utility failed to repair it
I cannot boot anymore after I tried to repair the disk with Disk Utility after my Mac became very slow.
This is the second time it happened to me in a week with the same symptoms. When I try to boot, I see a gray screen and the computer just stops
When I use the recovery partition, the disk utility fails to repair the disk, stopping after failing to fix the catalog file.
I started to use TM to backup my data after erasing the disk and reinstalling Mountain Lion but I wonder if my hard drive is damaged because the same problem happened twice. (Thanks TM for keeping my data safe this time)
Any advice or ways to fix that once and for all ?
PS : The worst is that i can still boot with Bootcamp to Windows, not very useful thoughrpignard wrote:
Any advice or ways to fix that once and for all ?
Since your Recovery HD and Windows partition work fine, the problem is located in your Macintosh HD partition and I very highly suspect it's bad/failing sectors that's to blame for your troubles.
This can sometimes occur if the computer was moved while the hard drive was in operation, else sectors fail all by themselves, or if the drive is having mechanical issues, which you problem will continue no matter what you do.
This time when you use Recovery > Disk Utility to erase the Macintosh HD partition, use the middle secure erase option, not the far left or right options (the right will work also just take a really long time)
What your doing is with the middle secure erase option is called a "Zero" write, which Disk Utility will write 0's over all the bits in that partition. When it's done it will read it back for confirmation and when it does so, any bits that are failing will be mapped off by the drive. Hopefully this will resolve the issue without needing a drive replacement.
Once that is completed, reinstall OS X from Recovery, any programs from original sources, files only from backup and your problems hopefully should disappear.
What happens is if your data gets corrupted on the boot drive by failing sectors, it gets transfered to TimeMachine (or to bootable clones) and when you restore your right back to square one. So it's important to rule out that possibility with original installs of OS X and third party programs.
If your problems continue, then it's possibly a problem with third party at boot kernel extension files, (and the catalog problem was yet another one) so to solve this you need to make sure all your third party software is updated and works with your current OS X version.
A trick is, if you get gray screen at boot time, is to hold the Shift Key while booting the computer, this will disable a lot of things and allow you to fix the third party software issue.
What I suggest you do is have multiple backup systems, including hold option key bootable clones, this way if your TM drive gets corrupted you can go back in time to a saved state on the clone, restore that and then your files from the TM drive.
