Sounds like a SCSI ID problem (2 items with same ID #) or a termination problem. If the Mac can be booted with each drive as a single drive try this:
Boot the Mac once with each drive attached so it can be read. Look at each drive in Apple System Profiler to get the ID # of that drive. Compare the 2 ASP profiles to see if they are the same # or not. Then you will know what # they are set at for sure. Change jumpers if needed. After you have the 2 profiles showing different drive ID #'s put both drives in at the same time and it should work. If not....termination is most likely the problem. A good program for SCSI drive mounting is SCSI Probe and can be found on any of the download sites. It's great for mounting all kinds of SCSI drives (Zip, HDD, etc..) without re-booting the Mac. Great for testing (mounting) SCSI drives without having to re-boot.
