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 I still cannot get Gnome rw tools to behave and K3b is complaining about few outdated packages which I am afraid to update since probably the Gnome depends on it but who cares.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

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

device          ses             # SCSI Environmental Services (and SAF-TE)

I also edited my load.conf file with


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:

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.
