You must plug that drive as Master.

[ ... ] >> Bus 0 and Bus 1 are separate (but not equal). Bus 0 is 10 MB/sec; Bus 1 is 5 MB/sec. You can have an ID 3 on the internal bus and an ID 3 on the external bus as well as SCSI Manager 4.3 separated all SCSI buses. These buses were "merged" into one, before SCSI Manager 4.3. On most modern Macs (except PowerBooks), the initiator (the mobo, in this case) is self-terminating. The last drive must be terminated. The unique thing about the external SCSI bus, Bus 1, is this bus is self-terminating for the target (the drive, in this case) as well, meaning that in most circumstances you can have no drive, an unterminated drive (which actually provides a "weak" termination) or a conventionally terminated drive, and all will be OK. -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
