You can turn it off using "tune2fs -c -1 -i 0". There are some superstitious people who will say you should not do that. However, if the O/S detects a dirty journal during a mount operation, it will run fsck.
I have some embedded boards that run ubuntu, and I turn them off by flipping the switch on the power supply, and I have never seen the journal get corrupted.
The same goes for NTFS. I have embedded boards running embedded XP, and I can turn them off without notice, and the journal is fine.
[RANT]You can create scenarios where a journal gets corrupted, but you really have to go out of your way. This is the benefit of using technology that has been around for many years. Don't ever let someone convince you that something is "bad" just because it is "old". The wheel is very old, but I rely on it for just about everything I do.[/RANT]
