You are on the right track with fx.  The Wren IV has been shipped on
all of the 4D platforms, and is a fairly reliable drive.  There have
been a few firmware revs on this drive with problems that show up
primarily on the PI (or the IO3 board) due to the higher transfer
rates.

Start up fx as 'fx -x' since you need to be in expert mode.  Since you
have a non-SGI drive anyway, just use the 'auto' choice.  This will set
parameters to default values, format the drive, create a partition
table, and write it out.  You should then be able to make a filesytem
on it with mkfs or 'Add_disk', add it to your fstab, and away you go.

Life would be so much easier if we could just look at the source code.
