Thank you.  I see the error of my ways, now.  I had tried just
about everything except -oro and that worked perfectly.

	Funny thing, it was /dev/sdc1 in this case but that was
pure coincidence.

	We normally have a stable power situation, here, but
recently we had 4 small glitches in one day plus several more
before and after that day and anything mounted rw usually needs
the fsck procedure afterward to be sure it is still any good.

	Nothing like power interruptions to make a fellow truly
paranoid.
