I'm in need of the format.dat entry for a Conner CFP2107S 2.1 GB hard drive
  for my SunOS SPARCsystem.  Actually, I've got everything except the
  controller.
I received no responses before I obtained the entry from Artecon:
disk_type = "Arte Conner CFP2107S" \
        : ctlr = "SCSI" \
        : ncyl = 3380 : acyl = 2 : pcyl = 3999 : nhead = 10 : nsect = 124 \
        : rpm = 7200 : bpt = 63488                         
partition = "Arte Conner CFP2107S" \
        : disk = "Arte Conner CFP2107S" : ctlr = SCSI \
        : a = 0, 52080 : b = 42, 132680 : c = 0, 4191200 : g = 149, 510880 \
	: h = 561, 3495560
Thanks to any who may be sending me a response before reading the summary.
