Hello there; I have replace the drives, I have replaced the controller.
I will replace the external cable, and switch from 'external active
termination' to 'drive built in termination' for the scsi bus.
It cannot be a driver/software issue, there are two busses involved, and
it is always the same one the on with the problem.

Is tehre something I am missing ?

I keep getting this on the console:
