How to find the mount point for my cd-rw in cdrecord

sirius57 · 03-25-2006, 08:30 PM

I am setting up cdrecord using gnome toaster as the front end. While trying to set up the cd rom and cdrw info, I was unable to locate the mount point and scsi id for the cdrw to plug into the gnome toaster software. I tried the scan bus button, but it did not autodetect the device. My box is using an atapi ide cd rom and a cd burner. Would also like to know what the command line syntax would be to use cdrecord in a terminal to copy files to the burner and to duplicate a cdrom.

If you're using an ATAPI CD, have you tried using cdrecord dev=ATA -scanbus to find your device? On my system I use the following to burn an iso:

Code:

cdrecord dev=ATA:1,1,0 padsize=63s -pad -dao -v -eject /tmp/cd-contents.iso

Also, I use the following from http://www.troubleshooters.com/linux/coasterless.htm as a shell script to create an iso from a CD:

Code:

#!/bin/bash
#
# See <http://www.troubleshooters.com/linux/coasterless.htm>
# Reads directly from the CD or DVD device specified on the command line amd dumps it to STDOUT
#
# Typical usage:
#                copy-raw-cd.sh /dev/dvd > /tmp/dvd-contents.iso
#
# To use this script to check the md5sum of the CD, do the following:
#                copy-raw-cd.sh /dev/cdrom | md5sum
#   compare the result with:
#                md5sum /tmp/dvd-contents.iso
#

device=$1

blocksize=`/usr/bin/isoinfo -d -i $device | grep "^Logical block size is:" | cut -d " " -f 5`
if test "$blocksize" = ""; then
	echo catdevice FATAL ERROR: Blank blocksize >&2
	exit
fi

blockcount=`/usr/bin/isoinfo -d -i $device | grep "^Volume size is:" | cut -d " " -f 4`
if test "$blockcount" = ""; then
	echo catdevice FATAL ERROR: Blank blockcount >&2
	exit
fi

command="/bin/dd if=$device bs=$blocksize count=$blockcount conv=notrunc,noerror"
echo "$command" >&2
$command

Hope it helps...

In terminal, I entered the cdrecord dev=ata -scanbus. I am pasting the results. It looks like some issues were noted by the scan and I am not sure how serious they are and if they need to be resolved. I am assuming the scsi address for the cendyne cdrw is 0,1,0? If the unit is atapi, why does gnome toaster need a scsi address?

That's correct, you'd refer to the Cendyne with:

Code:

cdrecord dev=ATA:0,1,0 blah blah

Whether the message for the other one needs investigation... I'd say try it and see - it may just be that with no CD in the drive it couldn't probe it properly, or that since it couldn't retrieve a brand name it tried its generic specs.

Although I haven't used gnome toaster, it's not unusual for applications to want to use SCSI for CD recording. CD recording with ATAPI drives was usually done with SCSI emulation under 2.4 kernels. With 2.6 series kernels it seems to be the preferred way is to use the device as ATAPI. Some apps like xcdroast will complain in ATAPI mode but still use it.

I am making progress. So far, I managed to drag and drop files, but could not make a recording. The top line says something like gnome filesystem. A right click on it opens a file dialog box. I point to the cdwriter, but nothing happens. In short, I do not know how to set up gnome toaster to record. I did a google search for gnome toaster docs, but what I found was scant help. I noticed in the terminal window when I closed gnome toaster, a bunch of repeated errors, something about not being able to set up the file system and filesystem does not exist.

You can get the user guide from http://gnometoaster.rulez.org/docume...s_guide.pdf.gz. Hopefully it'll have the info you need.

Thanks alot! That was the reference I was looking for. I had to configure the cdrom as atapi and the cdwriter as scsi. The cd rom reads and when I put a data cd in the writer, it listed the disk fill state. I am going to read the rest of the pdf file before I try to make a data cd and will post my results.

I read the docs and have the following errors:
In terminal window: 'couldn't create symlink'
and when I tried to burn a cd-r of mp3 files:
'The filter program for the suffix 'mp3' couldn't be found on your system.'

I have not tried pure data file yet, so I am not sure if this is just an mp3
issue or not. I am able to read the cd-rom and cd-rw drives, but unable to burn.
