RE: How to add another HD

You probably want to look at the ccd (concatenated disk) device in
FreeBSD. This allows you to do interleaving of multiple physical devices
into a single logical disk. On a FreeBSD sytem take a look at the manual
pages for ccd and ccdconfig. This should tell you everything you need to
know.
