A bit more info... why do I always figure these things out right after I
send a message?
It appears that the problem lies in the negotation of wide SCSI transfers
with the drive (which should support them):
----

Things appear to work fine in this configuration. The question is, why
does the wide transfer negotation fail? The drives use SCA connectors to
attach to the HSB, I don't know if that's relevant or not.
Thanks again,
