I've observed this behaviour as well on the 2GB wide Quantum Atlas. A test I performed, with tagged queuing enabled and with the maximum number of tagged SCSI commands set to one, resulted in a QUEUE_FULL status every 38 I/O's when doing a one block I/O operation. Setting the FUA bit within the 10-byte SCSI SCB "fixed" the problem but at a substantial cost to overall I/O throughput. As a result, I think a switch to a Seagate Barracuda may be in order - hopefully, it does not exhibit the same sort of behaviour.
