Absolute success!!! Media is completely readable. I still cannot get
Gnome rw tools to behave and K3b is complaining about few outdated
packages which I am afraid to update since probably the Gnome depends on
it but who cares. Command line rules!
Thanks a lot body one more time!

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
You need to use ATAPICAM if you want to use ATA cd-writers, see the
FreeBSD handbook:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/creating-cds.html#ATAPICAM
A small addition to the handbook:
You don't need to reboot your machine, the command:
$ kldload atapicam
Will load the module at runtime.
Use /dev/cd0 instead of /dev/acd0 for all writing purposes.
Maybe PCBSD does this automagiclly? Can't comment on that since I
don't use PCBSD.
