Just a small suggestion, that there may be an incorrect number of SCSI
Terminators in the loop.
There must be two and only two terminators present.
If you already know what you are doing Terminator wise you could try
installing the drives on another computer and swapping them for the other
computer's drives (as a diagnostic).
Hope that this will help.
