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(?): Index: linux-2.6.8.1-ck/drivers/block/scsi_ioctl.c =================================================================== --- linux-2.6.8.1-ck.orig/drivers/block/scsi_ioctl.c 2004-08-19 19:58:28.041430003 +1000 +++ linux-2.6.8.1-ck/drivers/block/scsi_ioctl.c 2004-08-19 19:59:01.705207615 +1000 @@ -193,8 +193,6 @@ static int sg_io(struct file *file, requ return -EINVAL; if (copy_from_user(cmd, hdr->cmdp, hdr->cmd_len)) return -EFAULT; - if (verify_command(file, cmd)) - return -EPERM; /* * we'll do that later (Note: I tried with 2.6.7 too, just in case I'm wrong, but same problem.)

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
