This may or may not be helpful, but I've noted that no one seems to be asking
or mentioning this fact.   (I could be wrong, I may have just missed it).

Here, Blaine specifies that his drives are external drives.  So I'm assuming
that they are set up as 

Internal - Lun 0, Unit 0
External - Lun 1, Unit 0,
           Lun 2, Unit 0,
	   Lun 3, Unit 0.

Hence, the LUN changes, but they are ALL unit 0.  Is this the common config,
or is someone else trying to use LUN 0, Units 0 and 1?  

I mention this because I have dealt with other types (non-Amiga) of SCSI 
controllers that DO have problems with multiple units on the same LUN, but 
DO NOT have problems with Multiple LUNS, all using unit 0.

Just a thought.
