I have the hard drives > on channel A (LVD ultra everything) and the tape drive *alone* on channel > B. Does that make a difference? Yes- normally that'd be the case if the second bus was indeed high voltage differential. *I* was confused by this too when I first got an LVD controller- I don't know of any that support low-voltage differential, single-ended *AND* high voltage differential- as far as I know, and maybe Ken/Justin will correct me on this, the LVD controllers we know of support SE/LowVoltageDiff- this does not include your DLT4000.
