I recently installed a DORS-32160 2.1GB into a sparcstation 2 without
difficulty.  It cost $359.00 from NCA, which seemed like a great price
for a new disk with a 5 year warranty.

Although ibm claims to have sun format.dat entries on their web page
at http://www.almaden.ibm.com/storage/techsup/hddtech/hddtech.htm, I
believe their entry for this particular drive is incorrect.

Instead, I used John DiMarco's excellent scsiinfo program, which
produced the following format entry, which I used.  I was then able to
format the disk and load sunos 4.1.3_U1 from CDROM onto it without
incident.

disk_type = "IBM DORS-32160 !#" \
        : ctlr = SCSI : fmt_time = 5 \
        : trks_zone = 33515 : atrks = 0  : asect = 0  \
        : ncyl = 6760 : acyl = 2 : pcyl = 6703 : nhead = 5 : nsect = 125 \
        : rpm = 5400 : bpt = 73500

I also contacted ibm technical support about the inaccuracy of their
entry. They seemed confused (and disorganised -- e.g. the email
contact address they advertise on their web page bounces). When I
finally got through to a technical support person, she stated that the
entry must be correct "because an engineer supplied it".

Best of luck.
