[Drew Jenkins]

How do I access it (through SSH) if it's unmounted?

Yes.   You just have to have everything on that disk unmounted.
Then you can run fdisk either directly or via sysinstall.   I have
lost track of where you have stuff you want to protect, etc, etc.
But a separate disk that you want to wipe and start over again on
can be fdisked, bsdlabeled and newfsed independently from the one
you are booted from and not affect anything on any other disk and
you don't need to be able to touch it, just unmount what is
currently there.
