Hi
This sounds suspiciously like the problem that I have been having with 3940s. I believe that
the current aic drivers are broken for 3940s - As soon as I try to use 2 hds at the same time
(either on the same or different channels) my machine hangs. I am currently using only one
drive on the 3940 and the others on a 2940 which is fine.
Hoping for someone to address this problem soon.
