Here the (rather strange IMO) output in dmesg: cd0: Removable CD-ROM SCSI-0 device cd0: 66.700MB/s transfers (UDMA4, PIO size 65534bytes) cd0: Attempt to query device size failed: UNIT ATTENTION, Power on, reset, or bus device reset occurred cd1 at ata0 bus 0 scbus6 target 1 lun 0 cd1: Removable CD-ROM SCSI-0 device cd1: 33.300MB/s transfers (UDMA2, PIO size 65534bytes) cd1: Attempt to query device size failed: NOT READY, Medium not present - tray closed I haven't the foggiest why cd0 behaves diffrently from cd1, which is a vanilla DVD drive and just works. --- Gary Jennejohn
