Thanks Jerry, the disktab was just what I needed to get the ball rolling.
For the benefit of the archives, here's a step by step to create a ready
to use Jaz cartridge that uses the entire 1Gb in one partition.
0) Find out where your jaz drive lives:
Look for 'iomega' in /var/log/messages e.g.
Jan 8 10:49:56 localhost /kernel: (ahc0:5:0): "iomega jaz 1GB H$70" type 0 remo vable SCSI 2
Jan 8 10:49:56 localhost /kernel: sd1(ahc0:5:0): Direct-Access
^^^
Later steps use "sdX" instead of "sd1" to try to avert disasters
==============
1) Low-level format the cartridge with:
scsiformat -w sdX
(this takes several minutes)
==============
2) Add a new entry to /etc/disktab
jaz1gb|Iomega Jaz 1GB - FreeBSD: \
:ty=removable:dt=SCSI:se#512:nt#64:ns#32:nc#1021:rm#5394:\
:pa#2090976:oa#0:ba#4096:fa#1024:ta=4.2BSD: \
:pc#2090976:oc#0:
==============
3) Label the disk
disklabel -r -w sdX jaz1gb
(this takes several minutes)
==============
4) Prepare a filesystem on the disk
newfs /dev/sdXc
==============
At this point you can do whatever you prefer, but here's what I did..
5) add the disk to /etc/fstab e.g.
/dev/sdXa /jaz ufs rw,noauto 1 1
mkdir /jaz
==============
6) Mount the new disk when needed
mount /jaz
corrections/improvements welcomed.

Thanks again to Jerry for getting me started. I was going around in circles.
