a possible culprit
Authored by: lugal on Mar 05, '03 11:04:57AM

I support over 400 Macs at a school. I usually get about one person a month come to me with this problem. For me, DiskWarrior always repairs the directory, but sometimes I still have to replace the damaged files with intact ones. In every case (under OS 9), the culprit is LimeWire. No lie: the cross-linked files are ALWAYS LimeWire downloads. So far, I've only seen this problem twice on OS X machines, but one case it was with LimeWire downloads, and once (on my own computer, no less) it was in Acquisition downloads. Now I'm very leery of these Gnutella clients--though perhaps the problem is with Apple's JVM.

Regardless of the source of the problem, though, I find that the longer it goes unrepaired the worse the damage to the drive becomes, eventually rendering the computer unbootable from its hard drive (though still repairable by DiskWarrior).

a possible culprit
Authored by: lugal on Mar 06, '03 01:00:45PM

Ok, so I must've pissed off the computer gods with my previous post. Last night, I had a kernel panic. Booted back up in single user mode, ran fsck, and found dozens of files with overlapped extensions and a couple multi-linked files. Using the advice on this thread, I found that they were all Chimera cache files. Deleted them, re-ran fsck, and am humming along happily again. So add my old copy of Chimera (2002122004) to the list of programs that don't clean up nicely after themselves. (Any sense in upgrading to a newer version of Chimera/Camino?)

Limewire
Authored by: WG Sea on Jul 14, '05 04:34:09PM

After 4 days I finally found someone that noted Limewire as being the problem.
I have tried the following repairs:
Disk Warrior found 2 Overlapped Extent Allocation Files but could not fix, ran several times.
First Aid continues to fix the HFS Volume, however I can never a get clean repair.
Target Disk Mode via Firewire does not mount HD on the host computer, however it is visable using Disk Warrior and Tech Tool Pro
I am using a iBook G3 running OS X

I would be very interested in learning how you resolved the issues of fixing the Overlapped Extent Files.

Thank you in advance,

WG Sea
