LG GSA 4081 B - Combo

2 months ago (before updating the system) my LG cd writer was working properly, I've been trying to burn an ISO image file (with k3b), recently and fineshed with a cdrecord error 254. It burns till a certain point and gives this error output.

I've done a google search on this errror but was not able to find any final solution to my problem, so I read

this tutorial and figured out that my lilo.conf file doesn't mentioned any "hdc=ide-scsi hdb=ide-scsi" line.

1)lilo.conf:

boot=/dev/hda
map=/boot/map
default="Linux-2.6.3-9"
keytable=/boot/us.klt
prompt
nowarn
timeout=200
message=/boot/message
menu-scheme=wb:bw:wb:bw
image=/boot/vmlinuz
label="failsafe"
root=/dev/hda5
initrd=/boot/initrd.img
append="failsafe acpi=ht resume=/dev/sda5 devfs=nomount"
read-only
other=/dev/hda1
label="windows"
table=/dev/hda
other=/dev/fd0
label="floppy"
unsafe
image=/boot/vmlinuz-2.6.3-9mdk
label="Linux-2.6.3-9"
root=/dev/hda5
initrd=/boot/initrd-2.6.3-9mdk.img
append="devfs=mount acpi=ht resume=/dev/sda5 splash=silent"
vga=794
read-only

 

2) k3b stuff:

[root@poseidon william]# rpm -qa | grep k3b
k3b-dvd-0.11.1-15mdk
libk3b1-0.11.1-15mdk
k3b-0.11.1-15mdk
libk3b1-devel-0.11.1-15mdk

3) cdrecord output

It reads cds and dvds quite well. The only issue is related to its writing capability. Any prompt reply would be very much appreciated.

Thanks.

If everything works properly, kernel 2.6.x doesn't require scsi emulation in order to burn cd. So the hdc=ide-scsi and hdd=ide-scsi line is not needed.

 

I'm afraid in Mandrake 10, cdrecord has a problem with supermount. I disable supermount and use magicdev for my laptop, so that I can burn properly. However my desktop hate magicdev, so I have to mount everything manually.

 

Although it is somewhat strange that cdrecord doesn't detect your IDE cdrom. Also, from what I see in your /etc/lilo.conf, it seems that you have a scsi harddrive? (from the line resume=/dev/sda5). My detected DVD-RW looks like this from cdrecord-scanbus

As you can see there is a line saying ATA interface. Since my DVD-RW is /dev/hdb, it is located in the second device of the scsibus. Do you enable devfs so that /dev/hdc and /dev/hdd goes into the right places?

I'm sorry DragonMage, but I'm completely ignorant regarding these issues: SCSI and ATA/IDE. I have a USB Maxto HD as cdrecord-scanbus properly detected, but that partition sda5 in lilo conf. is related to a swap partition I've created on this HD, so that I could be able to try other linux flavors. Why the hell it's there in lilo.conf?

"Do you enable devfs so that /dev/hdc and /dev/hdd goes into the right places?" How to check it?

Thanks all .

I got it working after playing around (un) plugging my external HD and zip drive, my gentoo ISO file was finally duly burnt. I figured out that the USB zip drive was fighting with the LG CDRW/DVDRW for a SCSI positioon, tried gcombust (device not recognised) even with the zip drive unplugged, upgraded from -9mdk to 2.6.3-14mdk, reinstalled k3b and at this moment these are the system's output:

My current fstab. I reformatted the 2nd HD and it's just waiting for gentoo (if I succeed in got it installed here) :P

[william@poseidon william]$ cat /etc/fstab

The zip drive is there in fstab, but before booting the system I unplugged it.

DragonMage, after the kernel update I went to MCC in the boot loader section and let the system choose for the default mode in the append part of lilo setup.

That is it...I'll keep playing around with these devices here in order to get both working together. In case of any query I'll don't hesitate to let you know.

 

Thanks!

This is my new fstab after attaching the zip drive to the computer.

[william@poseidon william]$ cat /etc/fstab

none /dev/pts devpts mode=0620 0 0

none /mnt/hdc supermount dev=/dev/hdc,fs=auto,--,umask=0,user,iocharset=iso8859-1,codepage=850 0 0
/dev/hda1 /mnt/windows vfat umask=0,iocharset=iso8859-1,codepage=850 0 0
none /proc proc defaults 0 0
/dev/hda6 swap swap defaults 0 0
none /mnt/zip supermount dev=/dev/sda1,fs=ext2:vfat,--,codepage=850,kudzu,iocharset=iso8859-15 0 0
none /mnt/zip2 supermount dev=/dev/scsi/host0/bus0/target0/lun0/part4,fs=ext2:vfat,--,umask=0,iocharset=iso8859-1,kudzu,codepage=850 0 0

zip1 despite of being mounted has no file on it while 2 is also mounted and full of files.

hotplug is stopped, harddrake is not. I've already seen an issue like this here.
