Hi All,
	Here is the summary to my recent post about getting
a write error with newfs.

Seems my parition sizes were slightly too large. Even using the original
Maxtor disk manuals before me for the ESDI disks XT4380E and XT8760E 
I couldn't seem to get the right number of total blocks. I got a couple
of excellent suggestions, but one in particular that worked great. Lets assume
as in my e-mail that my ESDI partition /dev/rra4f was larger than 
the physical amount of disk left(since it was my last partition). I can
use dd to find out the exact number of bytes on that partition that are
usable with this command,

# dd if=/dev/rra4f of=/dev/null bs=10k

This will output the exact number of bytes left on the disk. You can then
go back into edlabel and change the numbers for that partition. After I did
this newfs worked fine! Just for the record here is some of my labeling of
the 2 disks which currently works quite well! I only include the c partition
since that is all you should need to know for partitioning purposes. Please
note that the numbers for sectors, tracks, etc are what I pulled from
the Maxtor manuals I have! I found some different numbers online at
http://www.mm.mtu.edu/drives/maxtor/esdi/xt-8760e.txt
http://www.mm.mtu.edu/drives/maxtor/esdi/xt-4380e.txt
I don't know which numbers are truly correct, but what I have below
DOES work for me currently.

>From edlabeling of disks:

Numeric disk type? 5
Disk Name? xt4380e

interleave? 1

Thanks goes to David Brownlee, Lloyd Parkes, Carl Lowenstein and Erik Manders
amongst others for help in this AND the tms(0,0,0) *discovery* by
Alan Byer which solved my miniroot copy problem from before.
Thanks a million guys. Great job!

	Cheers,
