Just for grins I sent the command: "disklabel cd0". I got back a message
"/dev/rcd0: no such file or directory. The command "disklabel cd0a"
tells me (among other things) that I have 3 partitions labelled a and c.
(Go figure!) It also gave me:
disklabel: partition a: partition extends past end of unit
disklabel: partition c: partition extends past end of unit
Is this bad?

Good advice always! ;-)
