During the course toward FreeBSD 10 the ATAPI subsystem (acd devices) has been removed, and the access to the optical devices, connected to PATA or SATA ports, now relies on the "SCSI command language" (cd devices). Older tools that rely on ATAPI commands will probably not work anymore (cdcontrol and burncd from the base system come to mind). Also the kernel option "device atapicam" is not needed anymore; on FreeBSD 8 for example, it allowed you to use both "infrastructures" in parallel, e. g. acd0: DVDR <HL-DT-ST DVDRAM GSA-H42N/RL00> at ata1-master UDMA66 cd0: <HL-DT-ST DVDRAM GSA-H42N RL00> Removable CD-ROM SCSI-0 device You will now have to use programs like cdrtools, growisofs or cdparanoia to interact with optical discs which use the "SCSI command language". -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
