I have a very strange problem with my DVD-RW drive. Namely the drive is for some reason recognized as read only acd0: DVDR <LITE-ON DVDRW LH-18A1P/GL0C> at ata0-slave UDMA66 I am running FreeBSD 6.2 stable with generic kernel (I didn't compile nor install my own kernel) so the following lines are present in my GENERIC [pedja@ /usr/src/sys/i386/conf]$ more GENERIC # ATA and ATAPI devices device ata device atadisk # ATA disk drives device ataraid # ATA RAID drives device atapicd # ATAPI CDROM drives device atapifd # ATAPI floppy drives device atapist # ATAPI tape drives options ATA_STATIC_ID # Static device numbering # SCSI peripherals device scbus # SCSI bus (required for SCSI) device ch # SCSI media changers device da # Direct Access (disks) device sa # Sequential Access (tape etc) device cd # CD device pass # Passthrough device (direct SCSI access) device ses # SCSI Environmental Services (and SAF-TE) I also edited my load.conf file with hw.ata.ata_dma="1" hw.ata.atapi_dma="1" I altered the permissions devfs.conf and fstab file so that I can read and write but that is not even important since I can not write anything even from the command line I also get [pedja@ /usr/home/Pedja]$ dvd+rw-mediainfo /dev/acd0 /dev/acd0: unable to open: Inappropriate ioctl for device [pedja@ /usr/home/Pedja]$ dvd+rw-mediainfo /dev/cd0 /dev/cd0: unable to open: Inappropriate ioctl for device Whole behavior is even more strange since the optical drive was working flawlessly on PC-BSD 1.3 which is FreeBSD 6.1 stable. Any suggestions. Thank you so much
