You want this second disk for extra storage, right? Not for dual-boot or 
something?

Assuming extra storage, you could do what I did: Shut down the machine, 
install the second disk, power up the machine. Once you're booted, look 
at dmesg to see how the new drive was detected (maybe ad4? depends on 
your mobo's controllers and how/where the new disk was connected). I 
then ran /stand/sysinstall (this was back in the 4.x days) and created 
and newfs'd one big partition on the new disk. Then did #mkdir /usr1, 
and added an entry to /etc/fstab:

/dev/ad5s1c       /usr1       ufs     rw       2       2

...and suddenly there was another 160GB available under /usr1. Effect on 
the first drive: zero.

HTH... YMMV.
