I've got a 9404-400 running v4r5. The system has a Qic tape drive and CD. I have a 8mm drive that I want to add to the system. The expansion chassis has room and open connectors. I hooked up the new drive, but I cannot seem to make the system 'see' it. What do I need to do to make the system see the drive so I can use it?? Any suggestions are appreciated, Thanks in advance Terry
