I'm having some troubles reading and writing DVD+RW discs. I've
installed dvd+rw-tools and followed the instructions in the FreeBSD
Handbook and searched Google without much luck. Here's the specific
errors I'm getting:
Trying to mount the disc:
server# mount_cd9660 /dev/cd0 /cdrom
mount_cd9660: /dev/cd0: Invalid argument
Trying to burn stuff to the disc:
server# growisofs -Z /dev/cd0 -J -R /root/dumps
:-( unable to cam_open_pass("/dev/pass0",O_RDWR): Operation not permitted
When trying the same operations with a DVD-R disc, I can successfully
mount and read the disc, however I get the same error when trying to
write to the disc. The drive can also mount and read CD media just
fine. I've double-checked the permissions in /dev and I'm running
everything as root, so that shouldn't be a problem.
Here's some additional info to help in figuring out what my problem could be:
server# camcontrol devlist
<TDK DVDRW0404N 1.0A> at scbus1 target 1 lun 0 (cd0,pass0)
Here's some relevant stuff from dmesg:

Thanks for the help!
