$1E means that a WD-transfer command has been completed
successfully and that the next SCSI phase is a message-out
phase. Interestingly enough, the driver usually doesn't use
the transfer command!

Right.

IMHO, that sounds a bit weird!

Nah, probably won't make a difference.

Make sure the termination resistors are set up properly. Try
changing the order the drives are connected to the SCSI bus,
maybe reverse their SCSI-IDs. If this still doesn't work,
disable disconnect for both drives.
