Hello,

I recently acquired a Seagate Cheetah 9.1 Gig SCSI drive. I'd like
to use this to replace my straining 3 Gig drive I'm currently using with
FreeBSD 4.6.2.

Here's where I'm at so far:

WHAT WORKS
- During boot, the disk is correctly recognized as a 9.1 Gig drive
located at da0.

FROM THE try-to-slice-partition-and-label-it DEPT

	- Using /stand/sysinstall, the disk is identified as being half it's
	  actual size, and when I try commit fdisk options with it, a segmentation
	  fault occurs.

	- Using command line tools fails as well
		# disklabel -Brw da2 auto
		 disklabel: /boot/boot2 too large

	(details for both these points are documented in a related PR):
	http://www.freebsd.org/cgi/query-pr.cgi?pr=42217

FROM THE try-to-low-level-format-it DEPT

Since I have no attachment to the current 1024 bytes/sector arrangement,
I tried to low level format it to something that could cooperate better
with FreeBSD. Neither of these commands appeared to change anything.
"dmesg" still identifies the disk as 1024 bytes/sector:

 # camcontrol reformat da1
 # camcontrol cmd -v -t 10800 -n da -u 1 -c "4 0 0 0 0 0"

Any tips on how I can get over these humps and get this disk working?
Thanks much,

   -mark
