    I have the identical setup. I just use
    "cdwrite -v /dev/scd0"
    and it works for me (with an adaptec 1542 and a reasonably fast processor,
    both CDroms are on the same scsi bus).

    Generally, if your SCSI bus is clean, it will write clean. I knew someone
    who kept trying to load his system to the point that console switches were
    taking several seconds, but the CD wrote properly.
