When Apple first introduced journaling as the default with OS X 10.3, 
their tech notes made it sound as if running FSCK was a bad idea.  Even I 
was concerned about this.  (In fact my routine maintenance Web site still 
talks about this, I haven't updated it yet.)

But, finally, Apple clarified things.  You can still run FSCK, even with 
journalling enabled.
