Right. First of all, swap partitions aren't "mounted" as such. You
just have to tell the system to start swapping onto the partition:
# swapon /dev/ad1s1b
To make that happen automatically on reboots, add a line like so to
/etc/fstab:
/dev/ad1s1b none swap sw 0 0
In order to mount your /data partition, either you need to tell the
mount command all the parameters it needs:
# mount -t ufs -o rw /dev/ad1s1e /data
or you need to enter the equivalent data into /fstab so that mount can
look up what it needs to know there. There are some other fields in
fstab that 'mount -p' will give default values, but that you'll probably
want to set to something useful. Try something like this in fstab:
/dev/ad1s1e /data ufs rw 2 2
Oh, and do make sure you've created a filesystem on the partition before
you try and mount it..
# newfs /dev/ad1s1e
> Josh also mentioned "newfs"...
Chris Phillips thanks all as this is now SOLVED!
I was experiencing some difficulty, as if I added the said lines into
/etc/fstab, I would be unable to boot completely. This was possibly due
to the fact that when I used /stand/sysinstall to fdisk the drive &
label the partitions, it would seem to have not done anything... Oh
dear! I tried again (omitting the swap space as already have a big'un
on the 1st drive (ad0). I used the "W" option in the label editor which
seemed to do the trick & now with the fstab file looking like the one
below, things are wonderful again ;-)

I can now get the system back to normal, (having copied the contents of
the /data disk all over the place, while I reformatted it)... /usr
being somewhat crowded at the moment! That's not to mention me XP box
that's completely maxed out with copied data ;-)
