This is so similar to what I've been going through it's frightening.

Similar situation, where drive 1 appears to be causing failures on 
both disk 1 and disk 0.

My old configuration:

Disk 0                              Disk 1
Seagate 4096 (80M)                  Seagate 251-1 (40M)

This worked well.

New configuration

Disk 0                              Disk 1
Seagate 4096 (80M) 1                Seagate 4096 (80M) #2

BY ADDING A SECOND 4096 I got those same brutal errors that you are describing.

Either 4096 works find as drive 0 alone;  either 4096 works along with 
the 251-1 as drive 1.

I had concluded that either it was a fluky drive or uport 2.4 is having 
a problem with two 4096s in the system.  Now your posting suggests that
the problem could be related to having the 4096 as drive 1!!!!


SO,   anybody out there successfully running either TWO ST-4096s or running
a 4096 as drive 1?

I'd love to get this thing nailed down.  BTW, my new 4096 has been returned
to the vendor on the supposition it is faulty.
