It shouldn't be, but some times hardware misbehaves, etc...  I've had
a machine that ran SU+J on a CF to IDE adapter, and after some crashes,
a normal fsck would not make the fs clean, and required a manual fsck
to restore the file system to correct state...  I believe that it was
an issue w/ the hardware, but never tracked it down exactly...
