I have an external hard drive with a single HFS+ partition on it. I'd like to shrink this partition to make room for other partitions. It is to my understanding that I need to disable the HFS journaling before proceeding, and that journaling may be disabled from within MAC OSX.
I do not have access to an OSX machine so I was wondering if it was possible to disable Journaling from within Ubuntu?
P.D: I would rather not wipe the whole hard drive and create the partitions from scratch.
