I need the format.dat entry for a 3,5 inch SCSI disk drive from
Hitachi, type is : DK312C-25. What I found out up to now is:
--------------------------------------------------------------
disk_type = "Hitachi DK312C-25" \
: ctlr = MD21 : fmt_time = 4 \
: ncyl = 1074 : acyl = 2 : pcyl = 1076 : nhead = 12 : nsect = 38 \
: rpm = 3600 : bpt = ?????
--------------------------------------------------------------
As you can see above, the bpt-parameter is missing. I'd like to know
the appropriate value for that drive, or, better, a algorithm to calculate
it. The SunOS-Manual says about "bpt":
> must be assigned the physical number of bytes per track for the disk type.
> This number is used to calculate the boundaries for defects [.....]
Any help would be greatly appreciated.

Here's what we use:
disk_type = "Hitachi DK312C-25" \
: ctlr = MD21 : fmt_time = 3 \
: ncyl = 1074 : acyl = 2 : pcyl = 1076 : nhead = 12 : nsect = 38 \
: rpm = 3600 : bpt = 19456
