IDe CD Burner - Gnome toaster - newb


K, I added my CDR to the PREFERENCES > CD Recorder setup window as;

Device file : /dev/cdrom (like what my fstab says)
Mount Point: /mnt/cdrom
Scsi ID: 0,0 (already assigned)
"This Drive is a CD writer" [CHECKED}

I apply changes, select my burner, select the Ogg files i'd like to burn as data to the CD and get this in the little output window:

cdrecord: No such device. Cannot open '/dev/pg0'. cannot open SCSI Driver.
Child extied unexpectedly
CD recording process finished.

I did the 'cdrecord - scanbus' Im pretty sure it's a IDE/SCSI setting that im doing wrong. Can anyone help me out?

Thank you sooo much.

then at console, (cause toaster told me to do this):

[root@localhost bkeating]# cdrecord -scanbus
Cdrecord 1.10 (i686-pc-linux-gnu) Copyright (C) 1995-2001 J?rg Schilling
cdrecord: No such file or directory. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.


So I assume my system isn't even detecing my CDR? It's a brand new Liteon 48x12x48X

Have a look at the cd-writing howto it tells you all the settings you need to make. I just went through it myself and it works.

Ben, post here the contents of your /etc/lilo.conf file. Basically I am looking for the append line to have the scsi emulation in it. Also, is this a default kernel, and what distro if so? You might need a kernel rebuild, although I haven't come across a distro that didn't include support for scsi's by default so that'd be strange if you did.

Anyway, yeah post both the contents of /etc/lilo.conf and what "lsmod" returns.

Cool

Below are the changes I added to my system that worked for me..


lilo.conf

image=/boot/zImage-2.2.14
label=Linux
read-only
append="hdb=ide-scsi"


ADD TO /ETC/MODULES.CONF ( change the drive letter to suit your setup


options ide-cd ignore=hdx # tell the ide-cd module to ignore hdX
alias scd0 sr_mod # load sr_mod upon access of scd0
#pre-install ide-scsi modprobe imm # uncomment for some ZIP drives only
pre-install sg modprobe ide-scsi # load ide-scsi before sg
pre-install sr_mod modprobe ide-scsi # load ide-scsi before sr_mod
pre-install ide-scsi modprobe ide-cd # load ide-cd before ide-scsi


If your CD-writer is the only CD-ROM attached to your machine, then remember you have to access the CD-ROM in the writer through the device file /dev/scd× where ×=0,..,8. You may want to change the symbolic name cdrom to point to the new device file name. The listing below shows the command to achieve this with the example scd0.


cd /dev && rm cdrom && ln -s scd0 cdrom

should the module sg be loaded?
i don't see it there.

none of your burning software is going to work
if
cdrecord -scanbus doesn't see your drive.

try modprobe sg
