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

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 ;-)
