dvd burning problem, dvd+rw-tools, LG GSA-4120B



Hi all,

I just bought a LG GSA-4120B unit yesterday and immediately tried
burning a DVD-R with k3b (which uses growisofs), but it did not work.
I keep getting 03/0C/00 input/output (write) error.

I'm using dvd+rw-tools-5.21.4.10.8 vanilla.

Here are the relevant output and logs:

# uname -a
Linux mambo 2.6.8-gentoo-r3 #1 Fri Sep 3 16:08:26 EST 2004 i686 AMD Athlon(tm) XP 2800+ AuthenticAMD GNU/Linux

This particular kernel from gentoo has the following patch applied, so the
whole fuss about 2.6.8-scsi-whatever-dvdwriting-"bug"(*) should not be a
problem(?):

(Note: I tried with 2.6.7 too, just in case I'm wrong, but same problem.)

So, this is my 4th "coaster" so far :( all of them failed with the
same error, I tried with K3b, dvdrecord, cdrecord-prodvd.

What could be the problem? Any ideas?

In the meantime, I'm going to put the DVD burner in another PC with
Windows XP on it just to make sure that there's nothing wrong with the
hardware. (I could've done this yesterday but I was too pi**ed off to
do anything.) Currently I don't have any other media to try with, but
I'll buy different brands and type just to make sure it's not the
media, well actually I hope it's the media that's causing problem.

There is an official firmware update A111 from LG, I'm going to update
the firmware while it's in the XP box.

Thank you for your time and help.

Ronny
