     Dchech for Lev. II wasn't able to deal w/ hard links.  I was
supprised to find my OSk Dcheck didn't complain about a linked directory
on my MM1, though!  I haven't tried it with regular files yet.

"Sector......not in file structure" is not a fatal error.  The file
structure is still intact, but some sectors are blocked off for
aforementioned reasons.  For things you know about, I create dummy files
that hold those sector numbers so I can keep track of things.  For
example, I have a good number of bad sectors on my HD.  In /dd/sys/disk I
have files dead1 through dead4 that are effectively files spanning all of
those bad sectors.  When I first hit a bad one, I wrote a little program
that searched the disk for bad sectors and locked them out, and the ran dcheck
to get a list of these NiFS sectors.  I made /dd/sys/disk.  Used Build to
create a few empty files, and then used ded to fill them with all of the
bad sectors.  One of these days I'll write a nifty tool to take care of it
all at once...  I zapped all of the attributes on those files for now, to
remind me not to move their contents when I get around to writing a
speedisk like routine.  There should be a better way.

"sector ..... in file structure but not allocated" is bad.  Fix this :).
