I'm having difficulty getting a Maxtor XT-8760S to work in my Sparcstation
1+.  The data in format.dat is as follows:

disk_type = "Maxtor XT-8760S" \
	: ctlr = MD21 \
	: cache = 0x11 : trks_zone = 15 : asect = 5 : atrks = 30 \
	: ncyl =  1614 : acyl = 2 : pcyl = 1632 : nhead = 15 : nsect = 54 \
	: rpm = 3600 : bpt = 31410

partition = "Maxtor XT-8760S" \
	: disk = "Maxtor XT-8760S" : ctlr = MD21 \
	: a = 0, 32400 : b = 40, 64800 : c = 0, 1307340 : g = 120, 1210140

What seem to happen is that the controller reports an error whenever it
tries to access cylinder 1615. The error looks like this:

	Block 13089113 (1615/14/7) Fatal non-media error (illegel request).

This error occurs when it tries to access any sector/head on cylinder
1615. Note that that is the first cylinder where the label is written.

A low level format works okay until it reaches cyl 1615 and then it
reports the same error.

The drive is configured for drive select 2 (sd2) and LUN 0. It is the
second drive in the External Unit. The first drive is a SUN0669 (an almost
indentical drive to the maxtor) and it has been working flawlessly. The
system finds and recognizes the drive. probe-scsi also reports every thing
correctly.

The Sun manuals didn't say what this error means.

Any help/pointers would be greatly appreciated. I have spent about 3 days
playing with this thing.

Thanks,
