As Alex said, the scsi driver has a problem on your machine, but not all the messages indicate real problems. At one time I had a cdrom attached which didn't respond well to requests for synchronous working, and the driver couldn't cope. What devices do you have on your scsi bus? Can you disconnect everything except the Quantum HD as a test? You can try booting with sim700=nodisc:0xff in case it is a problem with disconnect/reselect, and you could try sim700=nodisc:0xff,noneg:0xff in case it is a probem with sync/async negotiation.
