First Kernel Panic - failed Disk Utility volume repair - Help?

Hello!
Well, you've seen the subject. 2 nights ago, after a long day of iTunes, Photoshop, Final Cut Express, and Halo, my powerbook had it's first kernel panic. When? When I unplugged my Lexar JD Lightning flash drive. I had just copied about 200 MB of music onto it (to copy to my imac), and ejected it. Instant panic.
Well, after a reboot, I ran disk warrior on all of my external drives - 2 USB (Western Digital 120GB, Iomega Exite 80GB), my Seagate 400 GB combo drive (Firewire), with 2 volumes, and my 4G clickwheel iPod - well, it's FAT32, so it didn't check it. (For use copying files to our winbox)
It worked properly, until I tried to repair the Iomega drive. It froze. Force reboot.
So, now I ran disk utility on my internal drive. While it was running, Backup started, and everything locked up. Force reboot again.
It rebooted and loged in just fine, so I restarted to the OS X install DVD (the one that came with the Powerbook - 10.3.7). I ran disk utility on Macintosh HD (boot drive). Permissions verification showed a few "special permissions". Permissions repair worked just fine. Disk verification found issues, and repair didn't work. It gave the following error while running:
"Invalid leaf record count. Should be 1 instead of 302"
In big bold letters, repairs failed. Odd, it checked 2 volumes -
at the bottom, it said
"Repair attempted on 2 volumes: (green text) 1 HFS volume repaired. (next line, red) 1 volume could not be repaired.
Right above this, in the progress window, it stated:
"The volume Macintosh HD was repaired successfully"
So, what? Is the second volume the install DVD?
My powerbook is running just fine, so I ran backup again. (the .Mac backup application from Apple)
Then, I ran Tech Tool Deluxe (3.03) - included on the AppleCare CD that came with our Applecare subscription for my Powerbook. It found no issues at all.
So, i'm clueless. I have not noticed any other issues. At least, since the issue.
Before this happened, I've noticed a few glitches. One is that iTunes has slowed down, particularly when changing tracks. The other is the menu bar battery indicator - sometimes it disappears - rather, the indicator. The space that it occupies in the menu bar remains empty, until you click on it - then it shows up fine. What's odd is that it's only the text - it's otherwise just fine.
What happened before the issue began? Well, I installed a new PNY ram card back around Easter - if that's the culprit, shouldn't it have shown an issue before now? Second: Installs. A few widgets, and a couple of applications: OS 10.4.7 and all other updates Software Update had to offer, Toast 7.1 update, Comic Life's new Universal version (a minor update, actually), Microsoft Office update (heh, probably that), and the trial of Salling Clicker - it's quite cool - Macworld (Aug 06 - new issue) gave the right rating (5 mice!). I dont' run permission checks enough, I know.
A while back, (like 10 months ago) my Powerbook wouldn't go to sleep. It turned out that it was one particular USB 2.0 hub - disconnecting it solved the issue. Its not unlike how my Seagate FW drive will keep my iMac from booting properly every now and then.
So, here are the questions:
1. What is the "leaf record count"? Is it very critical? Is it part of the physical HDD, or the system?
2. Powerbook's running fine, and no other issues. Is it okay to run?
3. If I need to repair/reformat (eventually), will it be sooner or later?
4. This seems rather odd, and very intermittant. How do I find out what the issue is?
5. What is the second, mysterious volume? Macintosh HD is not partitioned. (Could it be Classic?)
6. if the SMART status of the internal drive reports just fine, could it be missing something?
Thanks,
Daniel

Techtool Deluxe you want to be running version 3.0.4. Version 3.0.3 is not compatible with 10.4 and may be causing the leaf count issues. Here's the link to get an updated Techtool Deluxe:
https://support.apple.com/techtooldeluxe/main?id=dl
My suggestion is to start to simplify everything here. Leave everything disconnected from the machine, and boot off the Disk Warrior 3.0.3 CD, and repair the internal drive first. Use the Option key to boot:
http://docs.info.apple.com/article.html?artnum=106178
Once you are able to do that, then see if you can repair the external drives.
RAM issues can crop up at anytime, and without warning. No test can detect all bad RAM, but once detected, then you know it is accurate.

Kernel Panic and Disk Utility

I have a 12" 1.5 gHz PowerBook that runs almost flawlessly. Today I experienced my first kernel panic while running Call of Duty. My PB has Photoshop Elements 4, Popcorn 2, Dreamweaver MX, Macaroni, Tinkertool, and LittleSnitch as the only software other than what came with it. I am running 10.4.7. I also recently downloaded and installed the firmware update for my superdrive.
When I did the update to 10.4.7, I did all the things to make it go right, no problems until today and I don't think it is the update. I ran disk utility, verified disk, it indicated it needed repair so I attempted to repair it. It had something about 8 or 20 leaf? in the window and when it completed repair, it said HFS was repaired but volume could not be? Now when I verify, it says, "Incorrect number of extended attributes? and it won't repair. Now I am flummoxed. Ran TechTool Deluxe since I am on Applecare and it could not find anything, and I assume that the problem is something it won't find or repair. What is my next step? The PB is running well and this is the first time it has had a kernel panic. El P

hi el perdido--
did you try running disk utility a number of times?? also, you should repair disk and then select the first drive (not macintosh hd, but the other one) to see if smart status is available. it should say "verified". smart status is not always available. if you can't get it repaired, you could always try disk warrior. and if diskwarrior doesn't fix it, you will have to back up all info (which you should do right now anyway, if you think it's possible you can't repair your volume) and then erase and install. you can back up your info on an external drive, on disk, or if you have access to another mac, you can use firewire target disk mode. http://docs.info.apple.com/article.html?artnum=58583. let me know how it going.

Kernel Panic - nothing changed after volume repaired

Hi,
I have Kernel Panic and can only boot up under Safe Mode.
So, a bit of research via this forum, and I inserted the CDs belonging to my nephew to boot up using Mac OS disk as start-up disk.
After serveral tries with "C" key held down, finally got into the page with a nice background, and went on to Disk Utility.
So far so good, proceed to Repair, and the volume repaired.
Re-started, but back to kernel panic screen again.
Someone please help me.
I don't remember having my own CDs that come with the purchase.
My battery is dead so I am using direct AC power permanantly.
I thought problem solved if the volume is repaired.
I can't install using my nephew's installation disk either.
Someone please tell me what to do next. Thx.

Re: "kernal panic" or "gray screen of death"
I've just started having this problem on 2 of my 3 Macs. They are an eMac and an iBook, about 4 or 5 years old. Each is running OS 10.4 My 2 year old iMac, running 10.5, is fine (so far).
I get the gray screen with the instructions to restart (in four languages).
Since it just started happening on two separate computers, I would think that a hardware problem is ruled out (unless it's an extraordinary coincidence). Also, I see a lot of discussion about people having this problem after upgrading to Snow Leopard. Obviously, that's not the case either with these two older computers.
I've just installed a new Airport Extreme and an Apple TV in my house. When I did it, I created a new network rather than reconfiguring the old one. Could that be the cause???
For now, I've zapped the PRAM on each machine and that seems to have helped.
Here's the panic log from the most recent incident:

First Kernel Panic ever -- I would really apprec help on what this log mean

While charging up my ipod, I forgot to eject it before turning off itunes -- then I turned Itunes back on, then got my first kernel panic. Is this something to be concerned about? The message I got was as follows:

Disk Utility cannot repair startup volume, and where's my AppleCare cover?

Hi all,
The 250GB SATA drive on my Power Mac G5 Dual 2.5GHz has some 'issues' that Disk Utility cannot repair. It says, "Invalid sibling" and something about "key not found" or "keys out of order". I've run fsck -fy in single-user mode but it drops out saying "(4, 18880) error".
I have AppleCare Protection for it until November, but when I log into Apple's site, it says I have no current agreements. I'm at work at the moment and don't have my serial number, so I can't really call them up (and I don't have their phone number to hand...).
Is the hard drive covered under AppleCare?
I don't want to purchase any more software to fix the disk, i.e. Alsoft's DiskWarrior, unless it can be delivered instantly and will work on these problems?
Any help is much appreciated :o)

Thanks for that.
I was willing last night to re-install the OS to see if it was a software problem, but booting into the Tiger install DVD reported the same problems, however it was a little more informative than fsck. It says there are issues on the first two partitions on the boot drive. (I have OS X, Apps and Games partitions on that drive.)
I tried repairing the partitions in different orders, just in case it would help, but it still failed.
If I were to call AppleCare while at work, without the serial number, would they be able to locate my agreement and sort out a repair? APP was bought with the machine and I assumed it would've been registered at that time, but the website says I have no agreements...? Anyone got their phone number?

bob:
Disk Utility reports "Underlying task reported failure" when repairing a volume is a serious directory error which Disk Utility cannot repair.
•I suggest you read through the article.
•Then, if you do not have an up-to-date backup, it will be a good idea to try to save as much as you can of your data.
•The article suggests using a third party utility. Disk Warrior and Tech Tool Pro are the best utilities for this job. You will need to get one of them and run it, by booting from the CD, or installing it on an external firewire drive or on a second Mac which you can then run in Firewire Target Disk Mode.
Please do post back with further questions or comments.
Good luck.

My first Kernel Panic

I had my first Kernel panic on this PB. I bought it last May...has worked flawlessly until this afternoon when I turned it on for the first time today and immediately after desktop came on I got the black box message in 5 languages to "hold down power button " etc. No additional hardware has been added to this machine.

Any ideas what may have caused this???

Even if you didn't log in, the kernel extension for the Cisco Client still loads, and the panic would occur at that time.
As Maxit suggests, take a look at the panic.log file for other clues. I'm no expert at reading panic logs, but once in a while something sticks out that's worth following up on.
The DIY instructions for replacing RAM modules on the 15" PB are here:
http://www.info.apple.com/usen/cip/pdf/pbg4/pbg415fw800mem.pdf
Just because the problem hasn't recurred, doesn't mean that it won't come up again. On the other hand, anomalies do happen. Being aware that there may be an issue isn't ignoring the issue. Sometimes the only proactive steps one can take are keeping everything up to date, and running a clean system. When panics occur, it's always a good idea to run Disk Utility's Disk Repair tool from your Install and Restore DVD, or fsck -fy from single user mode or Disk Warrior just to be sure directories are in order.
Good luck!

Time machine: An error occurred while copying files. The problem could be temporary. If the problem persists, use Disk Utility to repair your backup disk.

Time machine backups are failing. I've followed the instructions I found on the Time Machine troubleshooting page (http://pondini.org/TM/Troubleshooting.html) but have gotten to where I don't know what to do next.
Sequence of events:
The main error message is always:
An error occurred while copying files. The problem could be temporary. If the problem persists, use Disk Utility to repair your backup disk.
Yesterday, I opened Disk Utility and verified the disk. Got this error:
Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.
I ran Disk Utility and repaired the hard drive. Then I manually started the backup before going to bed, figuring it was going to take a long time to run. When I got up this morning, the backup had failed with the same "could be temporary" error. I checked the log, which says:

Does anyone know what the problem is here and what I should do?
Thanks,

You have repaired your boot drive (which is good) but have you repaired your time machine drive? I don't own a Time Capsule so I don't know if disk utility can operate on it. If it can, you should repair it as well. You may need to erase it and start a new backup. That happens to time machine volumes from time to time and is why people who are serious about their data never rely on a single source of backup.

Have a mac book pro that crashed. ran disk utility to repair. comp booted and ran for short time. then crashed. ran repair again. disk utility said it could not repair files and i needed to format hard drive and start again. now nothing works

have a mac book pro that crashed. ran disk utility to repair. comp booted and ran for short time. then crashed. ran repair again. disk utility said it could not repair disk and needed to format and start again.
comp said it could not unmount disk and now when comp trys to boot all i get is a question mark on the screen. help

Erase and Install
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Quit DU after formatting completes and return to the installer. Install Snow Leopard.
5. After restart into Snow Leopard download and install Mac OS X 10.6.8 Update Combo v1.1.

Got my first kernel panic last night...

Last night, I got my first kernel panic on my mbp c2d. I've had it for about 3 months. At the time, I was downloading a file and surfing the web. I clicked on a youtuble link and all of the sudden i got that grey screen where it says to restart.
Right after the kernel panic, I restarted as it said and did a repair disk permission and it said it repaired a a flash player plugin or something like that. Do I need to worry about anything? I'm not very good with computers, and this has me a little worried. It seems to be working just fine. Thanks!

here is the actual log.

Disk Utility: cannot Repair Permissions, even on Leopard installation disk

After reinstall of iLife '08 and Software Update completed, I ran Repair Disk Permissions. Got an immediate red note "error: The underlying task reported failure on exit (sic)." with a flag: "First Aid failed. Disk Utility stopped repairing permissions on 'Mac HD...' because the following error was encountered: The underlying task reported failure on exit."
I went to my Leopard Installation disk and ran "Repair Disk." No problem found. From the Installation disk, ran Repair Disk Permissions. got the same RED INK comments and flag, First Aid failed.
Restarts don't help. Also, so far I have not found an application which is NOT working despite this Disk Utility problem, happy to report ;-))
Additional background. I was reinstalling iLife to fix iPhoto after a clean reinstallation of Leopard and reincorporation of files and apps vis Time Machine. It had been several weeks and iPhoto appeared to be the only app which was not quite right.

Disk Repair can trigger "underlying task" but I've never heard or seen a Permissions Repair do so.
You should never use the DVD to repair permissions. You should be using the same OS version. And of course you can always repair permissions from your boot drive; or from backup/clone or alternate "emergency" drive. Otherwise, the DVD and older version of DU will be wrong.
I know I read that on MacFixit, but I am not sure I bookmarked it.
Don't rely on Apple First Aid, even a clean bill of health doesn't mean there aren't problems which Disk Warrior can deal with.

Failed Disk Utility Software Raid

My external RAID hasn't been mounting as easily as normal so I opened Disk Utility to repair disk or whatnot and it shows one drive as failed. Not sure what this means or how I should proceed. I'd be surprised if that drive is dead. What does the Rebuild button do? I have backed up all the data on the mirror, but am not sure how to proceed. I'd like to keep this info on the RAID if possible.
Dual2 G5 & Powerbook G4 Mac OS X (10.4.4)

From Disk Utility's Help:
A disk in a RAID set has failed or is missing
Disk Utility monitors the status of the disks in a RAID set. If you see a message that a disk is missing or has failed, there are several things you can try to solve the problem.
If a disk is missing, make sure it is connected to power and turned on, and that it's connected to your computer. If you are using a FireWire or USB disk, you may need to disconnect it then connect it again.
Use the First Aid pane to repair the disks in the RAID, then check the RAID set to see if it still reports an error. You may need to unmount the RAID set to repair the disks.
In some cases, you might need to quit and reopen Disk Utility or restart your computer and then check the RAID set.
If you are using a mirrored RAID set, there might be an error while writing data to the disk. Click Rebuild in the RAID pane of Disk Utility.
If you are using a striped RAID set, delete the damaged RAID set. Your data may be lost. Be sure to back up the disks in your RAID set and other data regularly.
If you have a persistent problem with a disk in a mirrored RAID set, you may need to replace it. After you replace the damaged disk, click Rebuild to rebuild the RAID set.[/i[

DISK UTILITY STOPPED REPAIRING MACINTOSH HD!

So initially, my mac just was stuck on the white screen with grey apple logo and the spinning wheel. It wouldn't move! So I held down the power button and turned it off, let it rest for good 8 hours, turned it back on and it was still the same! With the help of some online postings: command + control + p + r, I got to the Disk Utility page and I tried checking for any damage. For most part everything was"ok" or "clear"! Then I ran 'VERIFY DISK' for MACINTOSH HD and some problems occurred. I clicked on 'REPAIR DISK' as promted. It said "DISK UTILITY STOPPED REPAIRING MACINTOSH HD: Disk Utitlity can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
I HAVE ABSOLUTELY NO IDEA HOW TO DO THAT ! I have not backed up a single thing on my mac!

If you want to preserve the data on the boot drive, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot from the Recovery partition or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

Disk Utility stopped repairing Mac HD - Now what?

My computer has been running slow so I cleaned up my desktop, trashed a bunch of old files and went to verify permissions. I was then told to use disk repair.
In the middle of doing so I got this message - "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."
Besides occasional slowness, my computer is working fine and I was able to get back to my desktop. Is this slow down issue going to get progressively worse if I don't reformat the disk? Should I do what the message says? If so, how? I've never reformatted before...it sounds a little scary.
I back up about once a week (just did so this morning) so I should be good to go there. I have AppleCare. Is this something I should bring the computer in for or can I fix this issue on my own?
Thanks in advance for any help.

Do as instructed. Get your self a backup drive if you don't have one. Backup your files. Then erase your OS X volume and reinstall Mountain Lion.
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.
