I was using it too.  But even with verified different scsi addresses for 
the drives, all I could get was a bus contention lockup.  I am told that if 
a separate ribbon is installed to the the disto's missing center lines are 
connected from drive to drive, that its supposed to work, so I cobbled up 
the other 16 connections with a separate piece of ribbon cable, but it 
didn't seem to make any diff, so I bought the TC^3, which does have a full 
50 pin interface.  They co-existed long enough to dsave the Maxtor to its 
own directory on the first Seagate.

Never looked back.  Didn't have to.
