Kernel Panic

I have been having issues with my 12" PB having random kernel panic events. A few weeks back I consulted apple care and we determined that the best course would be to "archive and install" or "erase and install". I did an archive and install first to maintain my account settings.

That didn't work, as the kernel panics started again. I then performed an erase and install after finding that there were no issues with my hardware after running Techtool Deluxe. A short time after my erase and install it started randomly hanging again... I think usually after it goes into sleep mode, but I can't pinpoint it to that.

In any event, today I ran disk utility. I booted from the tiger DVD and ran disk utility, repar disk. It failed to complete the repair giving the following:

------------------------------
"invalid extent entry"
"Volume check failed"
------------------------------

I ran disk utility again, this time booted into OSX. I ran the verify disk for grins. This was the result:

------------------------------
Verifying volume “Macintosh HD”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid extent entry
Invalid extent entry
Incorrect size for file libform.5.4.dylib
(It should be 0 instead of 1095216660480)
Incorrect block count for file info.nib
(It should be 0 instead of 16711680)
%)
Invalid extent entry
Checking multi-linked files.
Checking Catalog hierarchy.
)
Checking Extended Attributes file.
Incorrect number of Extended Attributes
Checking volume bitmap.
Checking volume information.
The volume Macintosh HD needs to be repaired.

Error: The underlying task reported failure on exit


1 HFS volume checked
Volume needs repair
-------------------------------

Does this mean that my drive is failing? I've been told that I may "have a hardware issue triggering your directory to fail, though the hard drive can't be discounted as a problem either."... Thanks A Brody

I have not called called apple care again as of yet. I'm afraid that I may have to send the machine in. Any help would be appreciated!

Thanks,
John

Hi John,

Since Disk Utility couldn't repair the disk, and it's obvious there are errors on the drive AND TechTool couldn't see the problem, at this point, (having a 12" PB
1.33Mhz myself, I would use DiskWarrior available here: www.alsoft.com
I've used TechToolPro and DiskWarrior on my PB, but it was DiskWarrior that came to the rescue three times.

If you don't wish to purchase DiskWarrior, I think it's time to call in the calvary and either sent it or take in for service. http://www.apple.com/buy/locator/

Well, here's the report from the latest crash. I don't know how to make heads or tails of these. I'm probably going to call apple care. This is actually my second hard drive...

Thanks for the link Carolyn. I found that theres an Apple repair center at the Circuit City near me. Hopefully I can take it there instead of sending it in.

John
