A quick response on this one brought in half-a-dozen entries in two
days - not all the same mind you...
Firstly a quick summary of the most common entry:

Thanks especially to Brian who enclosed a whole table of useful entries,
enclosed below with other replies.
Obviously with these clever SCSI controllers translating requests the exact
numbers can be jiggled a bit, but these are a useful starting point.
Thanks again,
Calum.

Here's what we're using on our Sun 3 with SunOS 4.0.3.
You'll note that it wastes a bit of space to stay under the 2**21 limit.
Remember to make all partitions (except 1) multiples of the 16-cylinder
group size, for the most efficient use of disk space.
I recommend using the default newfs options of optimize time and 10% minfree,
because we had some trouble with one partition when we used newfs with optimize
space and 1% minfree. Other than that, it's worked great since March.
Best of luck! -- Charlie <finnell%mdf@mwunix.mitre.org>

This is the format.dat entry for a Fujitsu 2266sa disk drive on a
Sun computer. You will only get 1.0737GB due to the SCSI limitation
in the SunOS drivers. If you format on a machine which uses
extended SCSI (i.e Solbourne), you can get the entire 1.2GB.
For more information, see Fujitsu Tech Tip #002 from 08 Aug 1990.
