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.

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[

After a failed disk utility fix my Macintosh hd is gone!

I tried to do a disk utility repair on my wifes white macbook and somehow my macintosh hd has vanished. I cannot even quit and restart unless I have the disk in, which is useless.....Need Help!

Well, I called applecare to see how much this was going to cost to diagnose and they said it was 49.00 per hour for a technician to try to diagnose over the phone. I hung up.....UGH! I had noticed on the front page of the support on apple.com there was a message about macbooks with 120Gb hard drives and a warranty program. This made me feel more confident my out of warranty hard drive had indeed crashed. I looked online at hard-drives at best buy, and found a 320GB for $59.00 This seemed like a decent gamble to me so I bought the new Hard drive. It was super easy to install and OSX started loading right up with no issues. Tomorrow I will try a trick I read about online about putting the old hard drive in the freezer to recover some media. Hopefully it works as my wife would like to get her pictures back. Thanks for all the help!

EMac G4 fails Disk Utility Verify

My eMac has been "on the shelf" since November. I drowned my "new" (rebuilt) iMac's HD so have taken the e out for a rescue mission. It seemed exceptionally slow with a few other quirks so I did a Disk Utility on the Volume HD as well as the HD itself and got this:

Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking multi-linked files.
Checking Catalog hierarchy.

Checking volume bitmap.
Checking volume information.

If you have the Install Disc handy...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
Other way...
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

I think I may have a virus on my MacBook laptop, ran disk utility, "filesystem verify failed." Help!

I'm running a MacBook laptop and thought I might have a virus b/c i was browsing online a couple of days ago when i clicked on a link that appeared to automatically start downloading a file. I tried to stop it from downloading by clicking "cancel" in the downloads box that came up, but it compleatly downloaded before i could hit cancel. No programs automatically opened and started runnning (that i could see), but I've noticed slow browsing since then.
I ran the disk utility, "verify disk," to see if there were any problems. It came back with this error message: "First aid failed: Disk Utility stopped verifying "Macintosh HD" because the following error was encountered:
Filesystem verify or repair failed"
The text is black inside the verifying history box until the last three lines, which say in red:
"Invalid node structure
Volume check failed
Error: Filesystem verify or repair failed."
Does this mean I have a virus? Are there other things I can do to confirm that I do or do not have a virus? How do I fix this problem?
I'm running Mac OS X 10.5.8.
Many thanks for your advice/comments in advance.

Probably because the directory on the disk is corrupt.
The error "invalid node structure" is one that will take either DiskWarrior or a reformat to fix.
It has not to with any malware.

Disk Utility Failed, Mac HD not working and cannot reinstall OSX

Hi,
I am totally frustrated.
Was working on capturing video using Final Cut Pro and the application froze. After repeated attempts, I kept getting the message to restart the G5.
I tried reinstalling Final Cut Pro - and installation failed. I ran disk utility first aid and found an error on the Mac HD (Startup Disk). So I restarted machine from the DVD (pressing the C button when restarting) and ran disk repair from the DVD OSX Utility. Still got the error that "First Aid Failed" Disk utility stopped repairing Macintosh HD because the following error was encountered. The underlying task reported failure on exit. HFS volume checked 1 volume could not be repaired because of an error. Repair attempted on volume 1, 1 volume could not be repaired.
Then I tried reinstalling OSX onto a second internal SATA HD. Installation failed. Try installing again.
So now what do I do?
I am running Mac OSX 10.4.9
Please help...urgent.
Thanks
MQ

Thanks for the answer...that's what I was thinking.
The following are various issues I am considering maybe the cause:
1. Memory - I installed 2GB a few weeks ago - third party.
2. External HDs - I installed an external Maxtor 1.5TB drive 3 days ago.
3. I live in Africa - and power frequently gets disrupted - even though the machine is on a "solatek" (power stabilizer and high end protector against spikes) - 2 days ago my UPS was down and for repairs - and we had three power outtages.
Lastly, as I mentioned I live in Africa - Mombasa - Apple tech support is almost non-existent here...so I am hoping I can resolve this without having to ship it abroad.
Please help and thank you...

Copying a drive with Disk Utility

I have a USB drive used for Time Machine that is failing. Disk Utility says it can't fix it, but says I can copy files from it.
I attached a new drive and am using Disk Utility's "Restore" function to clone the new drive from the failing one (both are 1TB drives).
Disk Utility says on the screen that it is "copying blocks". Does this mean it's doing an image copy rather than a file-by-file copy? It seems to me an image copy in this case might be bad, because it could cause any file or directory corruption on the old drive to be copied to the new drive.
Are my worries justified? Would I be better off just using the Finder to copy files? Are there third-party programs that might be better? (DiskWarrior says it can't fix the old drive because of insufficient memory.)

I have SuperDuper! but didn't have it installed on that machine and thought I would give the Disk Utility process a try.
I'm fairly sure SuperDuper! must use file copying, not image copying, and I suspect Disk Utility does too. But that "copying blocks" message made me wonder.
BTW, Disk Utility is telling me it's going to take over 24 hours to copy the terabyte. Both drives are connected via USB 2.0.

Disk Utility Error "no valid packages"

Hi,
I have a PowerBook G4 with 1GB RAM.
I've noticed a significant system slowdown lately. Programs take longer to open and respond, and it's rather annoying. I came to the forums to seek some remedy, and tried to run a Disk Utility to check that everything there is at least okay. But when I click on verify permissions, I get an error that says "no valid packages." Does anyone know what this means and how to fix it (if it needs fixing; I'm assuming this isn't a good thing, whatever it is!).
Thanks.
Lori

Hi librarygirl and Welcome to the Discussions!
Mac OS X 10.3, 10.4: Disk Utility shows a "No Valid Packages" alert
Disk Utility can't verify or repair permissions on the Mac OS X 10.3 or 10.4 volume if the "BaseSystem.pkg" file is not in /Library/Receipts.
This alert appears when you try to repair permissions with Disk Utility:
"First Aid failed
"Disk Utility stopped repairing permissions on '(volume name)' because the following error was encountered: No valid packages"
In the Disk Utility text window, this message appears in red text:
"Error: No valid packages (-9997)"
This happens when the BaseSystem.pkg file is not in /Library/Receipts.
Solution
If you've moved this file, move it back to /Library/Receipts. You shouldn't normally remove any files from /Library/Receipts.
If the file has been deleted, replace it by copying it from a different computer that uses Mac OS X 10.3 or 10.4, or by reinstalling Mac OS X 10.3/10.4 from an installation disc.
"Reinstall" means you can install 10.3 or 10.4 from a disc, if it's the same version of 10.3/10.4 (such as 10.3.3 on both the installation disc and computer). If the version of 10.3/10.4 on the computer is newer than what's on the install disc, then use the install disc to perform an Archive and Install installation instead, then update to a later version of Mac OS X.

Disk Utility Unable to Repair External FireWire Hard Disk

Hello all.
This is the External FireWire Hard Disk that has been giving me problems for days, it is a Backup/Clone Disk of my sis's Mac mini Core Duo, and may explain why it was so hard and took so much pain to copy some of the data out, at times it failed to mount, and I manage to rescue some data after using Disk Warrior, but Disk Warrior was also unable to replace it with a new directory.
Anyway, so I (was able to) mount the hard disk, and I was successful in erase and reformating it.
But when I (try to) repair it with Disk Utility's First Aid, this report is what I get:
(The usual 'Checking...' text lines, text in BOLD indicates RED colour text)
Checking HFS Plus volume
Checking Extents Overflow file
Checking Catalog file
Checking Catalog hierarchy
Checking volume bitmap
Volume Bit Map needs minor repair
Checking volume information
The volume Untitled could not be repaired after 3 attempts
Error: The underlying task reported failure on exit
1 HFS volume checked
1 volume could not be repaired because of an error
Repair attempted on 1 volume
1 volume could not be repaired
Then a window dropped down from the top says:
First Aid failed
Disk Utility stopped repairing "Untitled" because the following error was encountered:
The underlying task reported failure on exit
(OK Button)
I guess this hard disk is really a gone case?? I am quite OK just to replace it with a brand new one... maybe all the trouble I had in the beginning is because I may already have a faulty backup drive to begin with???
Thanks and cheers

Hi Kappy,
I knew there was something about "not mixing" PPC and Intel versions of dealing with the external drive.
The drive was originally prepared on an Intel Mac mini Core Duo. But it should also mount normally on a PPC mac as an external hard drive right?
Here's the sequence of events:
1. Tried to boot from the Back Up/Clone Drive of the Mac mini Core Duo, through my MacBook Core 2 Duo, but failed to boot up
I had to shut down the MacBook (prolonged Bluescreen)
2. When I reboot the MacBook, and tried to mount the ext drive as normal, nothing happens, I knew something was wrong
3. Able to reach the vendor, use the Mac mini again to erase and reformat the drive, then check with DU, everything is OK
Clone with SuperDuper
After that check again with DU, not everything is alright, there are errors.
4. Brought the drive home, try to mount on my iMac G5, nothing happens.
I did a check on this forum, and the reply was that I should be able to use Disk Warrior 4 (Universal) on a PPC to fix an Intel-based ext drive. I was very specific and detail in my post/question
5. So anyway, I have no other option, I ran Disk Warrior 4 from my PPC iMac G5 and scan the ext drive, trying to fix it.
It reported the drive is too damaged to be replace with a new Directory, but gave me a Preview Mode. I use this to copy some data out.
But not sure if the data is OK or not.
6. After that, I was able to mount the drive in my iMac G5, so I just use DU and erase and reformat the drive, with Zero Data
7. Ran DU again, and that's where I am now, at the very first post, getting error messages that I cannot fix the drive
Thanks and cheers

Help! PB G4 won't boot and Disk Utility can't fix it!

I have an insufficiently backed up PowerBook G4 1.67MHz (1GB RAM) that suddenly nosedived last night. I was surfing the Web and OmniWeb froze up. I couldn't force-quit it because the Finder was also locked up. So I held the power button until it shut down. When I restarted it, it got to the grey apple screen and hung there. I booted off the Tiger CD and ran Disk Utility, but it couldn't fix it. Then I tried booting into single-user mode and it also failed. Finally I tried reinstalling the system, but the CD couldn't find the hard drive. Aaargh!
I have a bunch of documents that I really cannot lose, and the most updated versions of them are only on this drive. Anyone know any tricks or third-party utilities that can help? I have another Mac; would Firewire Target Mode or Network booting help?
Some details:
Here's what Disk Utility said:
Invalid volume header (this was written in red)
Checking Catalog file
Keys out of order (in red)
Rebuilding Catalog B-tree (in green)
The volume [name] could not be repaired (in red)
Error: The underlying task reported failure on exit (in bold red)
1 HFS volume checked
1 volume could not be repaired because of an error (in bold red)
Repair attempted on one volume (in bold)
1 volume could not be repaired (in bold red)
Then it popped up a dialog box:
First Aid Failed
Disk Utility stopped repairing [name] because the following error was encountered:
The underlying task reported failure on exit (in bold)
Here's what single-user said:
It all booted normally, then I got these ominous entries in the list:
disk0s3: I/O error.
jnl: dojnlio: strategy err 0x5
jnl: open: could not read 512 bytes for the journal header.
hfs: late jnl init: failed to open/create the journal (retval 8).
nfs_boot: networking is not initialized
panic(cpu 0 caller 0x001F2634): nfsbootinit failed with 6
[then there's two backtraces here]
panic: We are hanging here...
PowerBook G4 Mac OS X (10.4.8)

As Mr Peck advised, DW is your best chance of getting out of this.
The important point of your post is the hard shut down (were you running Classic?) and the mention of Keys Out of Order. Do a search on these boards for Keys Out of Order for a quick education of the problem.
Make sure of the version of DW you use, get the disk and don't download, and make sure of your firmware version.

Disk Utility's "Verify Disk" does not work

For some reason I am not able to run the "Verify Disk" option in the Disk Utility application. I open up Disk Utility, I can click on the button, and it begins. However, while it says it is verifying the disk, and the status bar appears (just shows it working, doesn't show a time remaining), it continues like this for an inordinate amount of time. Eventually, the entire computer freezes up; I can move the mouse, but nothing responds to keyboard or mouse clicks. I am forced to hold down the power button to shut-down.
To get more information I decided to run this command in the Terminal. This is what I get:
+mycomputername~ root# diskutil verifyVolume /+
+Started verify/repair on volume disk0s2 Macintosh HD+
When I press enter after typing the first line, the second line appears, and it appears but nothing else shows up. Eventually, like in Disk Utility (which makes sense), the entire computer freezes up. (I've waited hours)
Does anyone know why this tool might not be working? I know, when using the terminal, more dialog should show what it is working on, which is why I find it strange it doesn't even get past the "Started verify" point. For example, the following is supposed to show up eventually, but doesn't:
+Checking HFS Plus volume.+
+Checking Extents Overflow file.+
+Checking Catalog file.+
etc...
I used the command line to verify with fsck too. +(sudo fsck_hfs -l /dev/disk0s2)+ This worked. From what I can tell, the problems it generated were benign.
On a different note, the reason I want to do this is because I am trying to use Bootcamp Assistant 1.4 Beta to create an XP Partition (after I had to get rid of it due to a virus), but it gets stuck on the "Partitioning Disk", and the status (which doesn't show remaining time) just continues to stay the same after a few hours, eventually freezing the computer in the same way the Verify Disk does. See a theme here? I'm not sure if this is related or not.
So why does the Verify Disk tool not work for me? Anyone have any ideas? I'm hesitant to try to use the Disk Repair tool, without the Verify Disk tool working.
Thanks for any help! Oh, and Happy New Year!

For some reason that didn't cross my mind. I booted with the OSX installer disk, and used DU and the Verify Disk worked!
Oddly enough when it finished I got an error message. Maybe that's just because the Verify encountered errors. It said:
+First Aid failed+
+Disk Utility stopped verifying "Macintosh HD" beause the following error was encountered: The underlying task reported failure on exit+
Here's the results of the scan:

+Error: The underlying task reported failure on exit.+
I'm going to repair the disk, only after I backup my data. Not sure if these problems are 'benign' or not. Maybe that will solve my Boot Camp problems, maybe not. If not, well, it's either a complete reformat of the drive, or I'll have to buy Leopard so I can get Boot Camp support.
Thanks for your help again! So nice to see something working right on my Mac, finally
Michael

I used the "erase free space " option in disk utility and now my imac says the disk is full and wont let me download songs. please help!

You could try repairing permissions with disk utility, I don't think you will have the option to repair the drive but you could verify it.
This may help you delete the files that DU made but did not remove when erasing the free space.

When you get your SL disk it will not have the iLife applications, that would have been on the second install disk that should have been with the computer. I forget which version of iLife you will need for SL but I think it is this http://www.amazon.co.uk/Apple-iLife-Single-User-Mac/dp/B003XKRZES/ref=sr_1_1?ie= UTF8&qid=1409607702&sr=8-1&keywords=apple+ilife+11
A search of the forums will confirm or deny this.
As to whether a clean install will cure your problem, i.e. partition the HDD and install I would expect it to be yes, but there are no guarantees it is an old machine.

Can't repair disk with Disk Utility

I had the spinning wheel of death on my G5 Imac so booted from instal disk and ran Disk Utility and got this message :-
First Aid failed
Disk utility stopped repairing disk 1 because the following error was encountered:
The underlying task reported failure on exit
In the list window when it got to checking catalog file I got
checking catalog file.
-Invalid sibling link
Rebuilding catalog B-tree.
-The volume disk could not be repaired
Error: The underlying task reported failure on exit
1 HFS volume checked
1 volume could not be repaired because of an error
Repair attempted on 1 volume
1 volume could not be repaired
Any suggestions? or is this the end of the road for my Hard Disk?
Would another disk repair program be able to repair this problem?
Thanks
John

Hi
I tried diskwarrior but but couldn't get to the rebuild directory page.
When I hit the agree button the screen goes grey with a spinning wheel then Imac reboots itself.
Tech support at D.warrior suggested resetting pram and open firmware but this makes no difference I'm awaiting further suggestions from them.
Any ideas here?
I ran a hardware test which showed nothing wrong.
Just read about target disk mode can link up and access my imac from my Ibook and repair the Imac with diskwarrior through the Ibook?

Disk Permissions will not run using Disk Utility app

I just recently (yesterday) ran disk utility to repair permissions and this is the message I received "First Aid Failed - Disk Utility stopped repairing permissions on “Macintosh HD” because the following error was encountered:
No valid packages" I ran it multiple times, restarted 3x and still the same message.
What in the heck in this? Never got this error message before.
Mike

Open the /Library/Receipts/ folder and look at the items inside; there should be roughly 62 items inside, which may significantly vary depending on your configuration. Some of these receipts are necessary for Repair Permissions to operate; if you've deleted these, you can copy them from another system. If you cannot get these back, you need to create another Mac OS X installation or reinstall Mac OS X on your existing system to get new ones.
