SCSI bus's are prioritized by id, with 6 having a higher priority than 4. It might be interesting to try swapping the ids on the two devices, and see if the problems follows the id, indicating it's a controller or bus problem, or the burner, indicating it's a problem with that burner. It may even go away, if the HP can deal with being at a lower priority better than the PLEXTOR, but I wouldn't expect that. BTW, what the data sources for the two cds? Are they on the same SCSI bus? http://www.mired.org/home/mwm/ Q: How do you make the gods laugh? A: Tell them your plans.
