I think I caught every thread on this, so forgive me if I am restating old news... Remember that some Quantum drives have buggy firmware. I believe it's the Atlaas series that have this bug. It seems they respond with QUEUE_FULL messages when their queues are not full. You can tell if you've got buggy firmware by checking to see if the revision level is L912. The most recent firmware is L915 and solves many problems aic7xxx users were seeing with these drives. ftp.qntm.com has all the tools and the firmware files needed to upgrade these drives.
