Thanks Mike, /dev/da18 works fine for me although I notice that
/dev/da18s1 does not.  There seems to be some inconcistencies
in this area.

Please tell me (and for the benefit of the list) as to why
I cant use /dev/da18s1c ?

Note that the disk has been set up with "fdisk -I da18" and
then "disklabel -wr da18s1".
