10/5    From a reliability standpoint, on an IDE hard disk, if you
        have write cache turned off, is there any advantage to using
        data=journal mode versus data=ordered mode? Related question, if
        I'm using data=journal mode, does turning write cache off have
        any reliability advantages?
        \_ I think the answer to the first question is yes, since
           I just read that data=ordered can result in corrupt data
           if power is interrupted while overwriting of a file.
