I don't think that would make much sense if the journal did not ensure the file data was safe, would it?

Just making sure the FS is in the correct state is no big deal. > > Having a UPS with ext2 is a godsend, but with ext3, a UPS helps but its > > utility is significantly less critical (as far as disk corruption goes). > UPS == good, unless the power supply is really good. > As I said, a UPS is good.
