"Journaling" is a feature that helps protect the file system against power outages or hardware component failures, reducing the need for repairs. Journaling was first introduced in Mac OS X Server 10.2.2, then to the non-server OS in Mac OS X 10.3 Panther."

HFS+ Journaling is MAC OS X ONLY and should not be used on any file systems that are to be written/read from Mac OS 9.

A quick tip for those who may have journalling enabled on a disk accidentally:
Journalling can be turned on/off
as noted in this url: http://support.apple.com/kb/ht2355
Note: In Mac OS X 10.4 and later, press Option to make Disable Journaling visible in the File menu.

NOTE:  some DAWs (Pro Tools) recommend your Audio Project Volumes be formatted as Mac OS Extended (Journaled)" format..

Digidesign recommends choosing "Mac OS Extended (Journaled)" format, instead of "Mac OS Extended."

Where some (Logic Pro) recommend Mac OS Extended...

Be sure that any drive you use to record audio is formatted Mac OS Extended. If you are using a dedicated drive or partition for audio recording, it is recommended NOT to enable journaling. If you are recording to your system drive or partition, then journaling should be enabled. Avoid using UNIX formatting, and don't record to drives formatted FAT32.

So it is best after you select your main DAW Host, to do some research...

this info you posted re: digidesign, are u sure this is not regarding PT6+ on Panther?

the main point of my post was that this can be toggled on and off from within disk utility in Panther + Tiger
as some wil have it on, and others will not have it on..
i had previously thought this was a seperate type of fielsystem alltogether (journling vs non-journaling) but it seems from the info in this technote they are the same.. and that this can be enabled/disabled on the fly

You can turn journaling on and off for disks on the server you are logged into by using Disk Utility or command line tools, with or without erasing the volume. For instructions, see "Mac OS X Server 10.2: How to Enable/Disable Journaling or Repair a Journaled Volume".

Yes Chris you are correct, Journaling can be toggled on or off... just like Novell TTS can be enabled or disabled...

I believe Systems like Novell were the first to institute TTS (basically the same thing as journaling), Way before OS X

The Novell Transaction Tracking System™ (TTS™) protects simple database applications by backing out application-based transactions that are incomplete because of a system failure. For example, a banking application might require that all steps in a user’s session be complete before updating the database and ending the transaction. If a system failover occurred and the transaction did not complete all steps successfully, all of the steps would be rolled back to their condition before the transaction began. If all steps of the transaction are complete, the TTS replays the steps and completes the transaction successfully.
To disable TTS on all Traditional volumes, add disable tts to the autoexec.ncf file.
