OK think I have a picture in my head now :-)
Have you checked the ID numbers of the drives ?
Have you made sure that none of the drives have there on-board termination set ?
Are any of the drives providing termination power to the bus ? (TERM POWER ... you need at least one drive providing it)
What drives are they ?
Just to be sure, do you have the terminators in the right places ? :-)
Are all the drives powered ? :-)
Are all the drives in the drive tray connected up OK ?
Is the drive tray earthed ? (ie. is it screwed into your case ?)
You came for answer and got more questions! :-)
