Hello, There are some weird problems with those dvd burners & atapicam. acd0: DMA limited to UDMA33, controller found non-ATA66 cable acd0: DVDR <PLEXTOR DVDR PX-716AL/1.01> at ata1-master UDMA33 acd1: DMA limited to UDMA33, controller found non-ATA66 cable acd1: DVDR <PLEXTOR DVDR PX-716AL/1.01> at ata1-slave UDMA33 I compile kernel with device atapicam and followed all steps from: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/creating-cds.html#ATAPICAM and on dmesg now I have: cd1 at ata1 bus 0 target 0 lun 0 cd1: <PLEXTOR DVDR PX-716AL 1.01> Removable CD-ROM SCSI-0 device cd1: 33.000MB/s transfers cd1: Attempt to query device size failed: NOT READY, Medium not present - tray open cd2 at ata1 bus 0 target 1 lun 0 cd2: <PLEXTOR DVDR PX-716AL 1.01> Removable CD-ROM SCSI-0 device cd2: 33.000MB/s transfers cd2: Attempt to query device size failed: NOT READY, Medium not present - tray open (cd0 is Light-On external DVD burner connected via USB) While burning DVDs with growisofs is working perfect I have problems reading them :) The only way to mount/read the DVD is to use /dev/acd0/1 - /dev/cd1,2 just does not work. When I try to access /dev/cd1,2 I have : Oct 9 11:50:09 thor kernel: (cd2:ata1:0:1:0): READ TOC/PMA/ATIP {MMC Proposed}. CDB: 43 0 0 0 0 0 0 0 4 0 Oct 9 11:50:09 thor kernel: (cd2:ata1:0:1:0): CAM Status: SCSI Status Error Oct 9 11:50:09 thor kernel: (cd2:ata1:0:1:0): SCSI Status: Check Condition Oct 9 11:50:09 thor kernel: (cd2:ata1:0:1:0): ILLEGAL REQUEST asc:24,0 Oct 9 11:50:09 thor kernel: (cd2:ata1:0:1:0): Invalid field in CDB Oct 9 11:50:09 thor kernel: (cd2:ata1:0:1:0): Unretryable error Oct 9 11:50:09 thor kernel: (cd2:ata1:0:1:0): READ TOC/PMA/ATIP {MMC Proposed}.
