OS X Script to Enable/Disable Journaling
Journaling is a feature of Mac OS X that is intended to protect the
integrity of the files stored on your hard disk drives. Using this
feature can protect against some of the kinds of file corruption that
frequently caused crashes, startup problems, etc., in Mac OS 9.
To learn more about journaling, read the excellent article at:

The
scripts below will turn on (or off) journaling for all connected
drives.
While these scripts have been tested by me and appear to
work fine on OS X 10.3.x and 10.4, I provide them here without warranty
or support, just “as is”. If they work for you and solve
a problem for you, great! If they don’t work, cause you to lose
data, lose your hair, or anything else, you agree that you assumed all
responsibility and liability when you decided to try the script out on
your system.
The scripts can be executed from the command line or
a cron task.
