It has been many moons since I have had to initialise a disk for long term 
use. And since then, many things have changed with VMS.

So, if I am to initialise a 30 gig drive with OSD5 structure, for use on 
VMS 8.3 (and VAX VMS 7.3), are there any parameters to INIT that I should 
focus on, or are the defaults optimal ?

Back in the days of 5.5-2 on my all might microvax II, I had a whole bunch 
of parameters, which I assume are now no longer necessary ?

Here is one original init command:

$!INIT $1$dua0: SHIMANO -
$!      /CLUSTER=12 -
$!      /DIRECTORIES=384 -
$!      /EXTENSION=24 -
$!      /HEADERS=300000 -
$!      /INDEX=MIDDLE -
$!      /MAXIMUM_FILES=490000 -
$!      /OWNER=SYSTEM -
$!      /WINDOWS=60


What is the optimal cluster size these days ?  Any other parameters I 
should tune ?
