ext3 is a journaling file system, ext2 is not. If you shut off the power to a machine that is running ext2, you will have to go thru the "equivalent" of scan disk to get things back in order. With a ext3 system, the journal takes care of this for you. Greatly simplified explanation, but that is the gist. ext2 will take long time to boot up after power cycling a machine.
