I have 2 Quantum 2.1 GB hard drives (Model - XP32150) and an atlas CD-ROM. I want to add a Quantum 9.1 GB hard drive (Model - VK309100LW). I have not yet bought it, but plan on getting it because of the success I have had with my other Quantum drives. The adapter I have been looking at has "high byte termination." I am currently using an active terminator at one end and the 2940 at the other end. Does it matter where I put the new drive? My guess would be to put the new drive as close to the 2940 as possible. It would then look something like this: 2940 | | |-- Adapter and new 9.1 GB Quantum | |-- 2.1 GB Quantum | |-- 2.1 GB Quantum | |-- Atlas CD-ROM | |-- active terminator At 11:43 PM 6/7/98 +0200, Wilko Bulte wrote: >As thehades wrote... >> I have a Adaptec 2940 narrow host adapter with two hard drives and one >> cd-rom.
