It is possible to use the Wren 7 on the 817 under 8.0 or later, and it is
possible to partition this drive (within some restrictions) into multiple
data and swap areas. I've done this with other non-HP drives quite
successfully.

At the most basic level you should reference the device file/partition
cLUd0s2, where 'LU' is the logical unit (from the ioscan -f command),
and 's2' refers to the second partition;
well, in HP notation, the entire disk drive. Newfs s2, mount it & away
you go.

(Personally, I use disksecn to define the sections and create the disktab
entry.)
