jumper settings for maxtor XT-4380E

[gt1998b at prism.gatech.edu]

We had a heck of a time formatting a Maxtor drive on a Sun 3/60. I can
show you how we did it. You have an XT-4380E but we have an XT-8760E.
After several calls to Maxtor, we got ahold of an informed technician (our
first call got a reply like "A Sun computer? No, our drives only go into
pc's.").

Anyway the Maxtor tech said that we should place the drive in hard sector
mode and hard configure it for 52 sec/track. but our format.dat should say
nsect =50.

Here is our working copy of our format.dat for that drive.

# WARNING: this disk must be driven in hard sector mode and hard-configured
# for 52 sectors/track.
#
disk_type = "Maxtor XT-8760E" \
	: ctlr = MD21 \
        : ncyl = 1616 : acyl = 6 : pcyl = 1632 : nhead = 15 : nsect = 50 \
	: rpm = 3600 : bpt = 31410

partition = "Maxtor XT-8760E" \
	: disk = "Maxtor XT-8760E" : ctlr = MD21 \
	: a = 0, 97500 : b = 878, 63750 : c = 0, 1212000 : g = 130, 561000 \
	: d = 130, 280500 : e = 504, 280500 : f = 963, 489750 : h = 0, 658500

Hope this helps.

PS: Our drive has been running without incident for several months.
