Original problems:
===============================================================================
1) can anyone give me a format.dat entry for a Micropolis 3243 4.2 GB
disk
2) after installing a format.dat entry, I get weird errors.
===============================================================================
The crux:
The questions really should be unnecessary since I received essentially 2 kinds
of reply: RTFFAQ and look at www.micropolis.com. Both sources give the entry:
(Note: this has been corrected so the partition entry works!)
-------------------------------------------------------------------------------
disk_type = "Micropolis 3243-19" \
: ctlr = SCSI : fmt_time = 9 : rpm = 7200 \
: ncyl = 3154 : acyl = 3 : pcyl = 3956 \
: nhead = 19 : nsect = 139 : bpt = 65536
partition = "Micropolis 3243-19 v1" \
: disk = "Micropolis 3243-19" : ctlr = SCSI \
: a = 0 , 66025 : b= 25, 132050 : c = 0 , 8329714 \
: g = 75 , 4193908 : h= 1663 , 3937731
-------------------------------------------------------------------------------
I used this and it works fine. This is very DIFFERENT from the format.dat entry
from ftp://ftp.ra.mcs.anl.gov/sun-managers/format.dat:
-------------------------------------------------------------------------------
disk_type = "MICROPOLIS 3243-19" \
: ctlr = MDF21 : fmt_time = 9 \
: ncyl = 4139 : acyl = 2 : pcyl = 4141 \
: nhead = 19 : nsect = 106 : rpm = 7200 : bpt = 63282
-------------------------------------------------------------------------------

My problems came from a wrong entry I "cobbled together" (as John DiMarco puts
it). It is not intuitive how ncyl, acyl, and pcyl fit together in the entry
that works.

Important quotes and tips:
1) USE SCSIINFO. Source for this is given in the sun-managers FAQ
A VERY useful tool for Unix systems.
2) On SunOS 4.1.2, partitions are limited to about 2 GB
3) The bigger vendor companies have web pages with lots of useful information.
4) Barry Leibson had problems with more than one of this model disk. Maybe
a bad production run. Mine is working fine right now.
5) Read the FAQ -- I finally read it when Fuad Khalid sent it to me.
