More than that, you should see an entry like: at scbus0 target 5 lun 0 (pass2,cd0) ...mentioning the CD/DVD device; the entry for xpt0 is simply the driver interface itself, not a reference to a particular device. > I don't have a cd0 entry in /dev so trying growisofs with it give this: > :-( unable to open("/dev/cd0c",O_RDONLY): No such file or directory > Also dmesg show this line: > acd0: DVD-R at ata1-master PIO4 > which pretty much shows that the drive is being recognized and put at > acd0 Right, but the acd device ['man 4 acd'] and the cd device ['man 4 cd'] are not the same-- that's what the CAM subsystem is for, to provide passthrough emulation for ATAPI devices so that you can send SCSI commands to them. The "burncd" program works with ATAPI devices directly; the programs with dvd+rw-tools need CAM. Hmm, also you should be configuring your device to enable UltraDMA modes rather than PIO; try a "sysctl hw.ata.atapi_dma=1", or equivalent in /etc/sysctl.conf or /boot/loader.conf. -- -Chuck
