ToggleJournaling:
ToggleJournaling does exactly what it's name implies: it toggles file system journaling
on and off. Allows enabling/disabling file system journaling on multiple volumes
individually, so you can have it enabled on some volumes and not on others.FILE
SYSTEM JOURNALING is normally a GOOD THING that helps PREVENT DATA LOSS! Using
this app will absolutely void your warranty! ADVANCED USERS ONLY! USE
AT YOUR OWN RISK! Et cetera. Useful for advanced users who have a dedicated swap
partition or drive so that they can turn journaling off for the swap volume and
leave it on for the boot volume, also for machines that don't have much important
data on their local drives, like machines that start via Net-Boot, machines that
are used only for print servers, machines that are used only as part of a render
farm, et cetera. For machines such as those turning off file system journaling
may result in slightly faster operation and quicker boot-up and shut-down.
Just to re-iterate, do NOT disable journaling on ANY drives that contain important
data. Requires OS X version 10.3 or later and the BSD subsystem.
