A possible fix for 'overlapped extent allocation' errors
Authored by: smkolins on Mar 04, '03 01:44:49PM

I agree. There is actually nothing new here. If you happen to know or figure out what's crosslinked you could always delete just those parts and ussually recover pretty gracefully. Figuring out what's crosslinked may be hard. In this case he just guessed and guessed correctly.

This just underscores one thing about the OSX force quit process. Yes the ram/active OS may be ok, but no there's no gaurantee the hd is.

Would turning on journaling help Disk Utility and/or fsck in fixing these problems? Just a thought ;)

A possible fix for 'overlapped extent allocation' errors
Authored by: smkolins on Mar 05, '03 08:26:29AM

Interesting thought....

I'ld like to see some experiments.

However until then... my thoughts are... that it would still crosslink. Journaling does check the sanity of the requests for allocation as far as I know. It just checks that they were accomplished. Still I suppose it's possible journaling would read the incoming requests as undelivered and not execute them, or delivered, find them unfinished, and execute them correctly at boot.

Definately need to test this!

I have had my harddisk journaled since 10.2.3, but the number of the overlapped extents had gone up since then. There used to be about 4, now there are 10!
