Cf. section 6.6.6, "DISCONNECT":

"  Targets that break data transfers into multiple connections shall
end each successful connection (except possibly the last) with a SAVE
DATA POINTER - DISCONNECT message sequence."


Anyway, you can't determine the residue from the bytes transfered over
the SCSI bus.  In a multi-block transfer the target might report an
error for the first block after it has transfered later blocks over
the bus.

You don't need to quote my .signature.  Everyone has seen it by now.
Besides, it doesn't add anything to the current thread.
