Double-check what's going on with your devices, what does "camcontrol

Here's what camcontrol had to say: # camcontrol devlist -v scbus-1 on xpt0 bus 0: < > at scbus-1 target -1 lun -1 (xpt0)

I'm guessing there should be something there between the < >.

More than that, you should see an entry like:


<NEC CD-ROM DRIVE:465 1.03> 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 <Memorex DVD+/-RW Dual-X1> 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.
