==================== Original Query =========================================== Hello all.
I am looking for the format dat for a Fujitsu M2652S 2.0 gig drive.
If anyone has got one could you please send it on ?

Here is a disktab entry I created for my NeXT, along with the key to
the format. I suspect the obvious translation will work fine on the
Sun, but please summarize anyway so I can put the Sun version in my
format.dat list.

I've been using:
FUJITSU M2652SA: ncyl=1935 acyl=2 pcyl=1937 heads=20 sectors/track=88
I didn't create a format.dat entry, these are the values that the
drive came with from Dilog (now called Open Storage Solutions). I
have no idea if this is the best that can be done or not, I haven't
had time to play with the parameters.

Hi Larry, I just posed this question in comp.sys.sun.admin and here
is a reply that I received.
--sandra
-----------------------------------------------------
Here's one I got directly from Fujitsu support that's
working perfectly...
disk_type = "Fujitsu M2652SA" \
: ctlr = SCSI : fmt_time = 4 \
: ncyl = 1935 : acyl = 2 : pcyl = 1944 : nhead = 20 : nsect = 88 \
: rpm = 5400 : bpt = 52864
==================== Rafi Sadowsky <rafi@tavor.openu.ac.il> ==================
this is not optimal but it works ...
[I have an untried entry built according to the OEM manual somewhere
if you'r feeling adventerous - mail me and I'll dig it up
you might gain ~30+ M as far as I recall ]
---------------------------
# You should leave all jumpers in their default factory settings except
# you must open jumper 5-6 on CNH1 and open 11-12 also on CNH1.
disk_type = "FUJI-M2652-2G" \
: ctlr = MD21 : fmt_time = 3 \
: ncyl = 1934 : acyl = 2 : pcyl = 1936 : nhead = 20 : nsect = 88 \
: rpm = 5400 : bpt = 52800
