[comp.unix.xenix] 2nd disk with Microport: Warning

rcw@qetzal.UUCP (sysop) (06/28/87)

I have attempted to add a second hard disk to my AT clode (an
IMS 286). My main disk is a 40 meg atasi, the second disk is
just a seagate 225 that was sitting around. Before I could afford
the ATASI, microport ran on the trusty seagate.

My machine has 1 control cable for two disks, the last connector
has a twist in it. Manual said to set both drives to "D" position,
remove the terminator resistor from the middle of the chain. 
This never worked, so I made the last drive (ATASI) "C" and the
seagate in the middle of the cable "D", and removed the terminator
resistor from the seagate.

So far, so good. Microport booted up off the ATASI. As per
the microport instructions, I typed:

format -s /dev/rdsk/1s10 

Low and behold, the seagate formatted. When it was finished, it
tried to update a block on the ATASI, thus destroying the 
partition information. I was never asked, it just did it. This
has happened to me twice, and am about to give up on using 
two disks. It takes half the night to get unix and news
reinstalled after a disaster like this. Possibly related:
the ATASI had to be formatted with special software, the seagate
can and has been formatted correctly with Microport's format.

FLAME ON: I've installed a fair amount of hardware on other 
machines. It seems like I have to fight every peripheral I've
ever purchased for these damn ATs. The documentation seems to
omit the most crucial information in an attempt to be "user-
friendly." The everex manual, for example, for the ram 3000
(which I also can't get to work) is friendly to the point of
nausea, but neglects to give solutions to my problem. (256k base
384k extended at boot when it should say 640k base, 1408 extended)
If anyone is interested, we could stage a public computer
document burn in protest.
FLAME OFF:
