I had bus problems with my DNES until I upgraded the firmware to: da2: <IBM DNES-318350W SAH0> Fixed Direct Access SCSI-3 device In general, I have often seen bus problems when a lot of different devices are hanging on the same SCSI bus and some drives are being hit really hard. They always went away with a new fw, especially on my IBM DDYS drives. The Plextor fw seems a bit old as well (at least compared to my PLEXTOR CD-ROM PX-40TS 1.13) but I don't know if the 32TS uses the same as the 40TS. I have written a program to upgrade the firmware on IBM and Plextor (and some other devices) under FreeBSD in case you are interested... However, IMO one should play with the fw only in case of problems and not just to get lastest version... -Andre To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
