This questioning is a little like the following question: "I haven't made a backup for 3 years, with nothing bad happening. Are backups a placebo?" Of course the answer is no - you don't need a backup until you need one (and you _may_ never need one). But since you can't predict when you need a backup, regular backups are still a good idea. Journaling is the same kind of thing. The OS uses it for recovery from system crashes. If you never have a system crash, your computer probably will derive no benefit from journaling. Even if you _do_ have a system crash, you may be OK without journaling, but you might experience data corruption, depending on what is happening on your machine. (Of course in the event of a crash, you might have data corruption even with journaling on, but it is less likely.)

It makes no difference to the chance of something bad happening but if something bad does happen then you may be better off with journalling enabled. So no, it is not "just a placebo" any more than wearing a seatbelt or crash helmet. Ian -- Ian Gregory http://www.zenatode.org.uk/
