how to configure CD-RW to burn AND play

cpv204 · 06-10-2003, 09:16 AM

Hi, I'm trying to configure my system to burn CD's. I set up scsi emulation for my drive by putting hdc=ide-scsi in my grub.conf and adding insmod ide-scsi to my rc.local. I run cdrecord --scanbus and my device is listed in the resulting output.

However, now that I have turned on scsi emulation, I can't play CD's through xmms any more. It doesn't even recognize that there's a cd in /mnt/cdrom

What do I need to do to configure my system so that I can burn and play CD's without having to change configurations in between?

Thanks

Run the following command in the /dev dir
"ln -s scd0 cdr"
Add the following to the /etc/fstab
*/dev/cdr /mnt/cdr iso9660 noauto,owner,ro 0 0

mount it like this...
mount -t iso9660 /dev/cdr /mnt/cdr

thanks phishy!

So I was only one symlink away? I'll report back tonight.

No problem, that set-up has worked for me many times. I assume it will work for you.

Hmmm, not working. I made the symlink from /dev/cdr to /dev/scd0:

Code:

bash-2.05b$ ls -l cdr
lrwxrwxrwx    1 root     root            4 Jun 10 19:50 cdr -> scd0

and created the entry in /etc/fstab:

Code:

bash-2.05b$ less /etc/fstab
/dev/hda5        swap             swap        defaults         0   0
/dev/hdb2        /                ext3        defaults         1   1
/dev/cdr        /mnt/cdr        iso9660         noauto,owner,ro   0 0
/dev/hdd4        /mnt/zip         auto        noauto,owner,users,kudzu 0 0
/dev/fd0         /mnt/floppy      auto        noauto,owner,users,kudzu     0   0
/dev/hda1        /mnt/winc        vfat        auto,owner,users,umask=000 0 0
/dev/hdb1        /mnt/wind        vfat        auto,owner,users,umask=000 0 0
/dev/hda3        /mnt/rh          ext3        defaults 0 0
/dev/hda2       /mnt/rh/boot      ext3        defaults 0 0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0

and made sure that xmms is configured for device /dev/cdr and directory /mnt/cdr (which does exist). Still, xmms "sees" nothing on an audio cd.

Interesting to note: if I put in a data cd and run mount /mnt/cdr, I can see the files on the data cd and xmms can see them, too, but when it comes to an audio cd (can't mount one of those) xmms comes up empty.

Any thoughts?

Try this:

The instructions originally were written for Slack 8.1 but I've got Slack 9.0 installed, and they work perfectly. I similarly was having a bear of a time trying to figure out why things didn't work, but these instructions solved the problem in no time flat. Good luck with it. -- J.W.

PERMISSIONS!

I hadn't run chmod 666 /dev/scd0

Everything had been configured properly, but I just needed user access to /dev/scd0.

Thanks J.W., it was a simple thing, but I wouldn't have spotted it. The MP3 CD Burning HOWTO doesn't mention this...interesting.

Since MP3 are tecnically data, it's entirely different then an audio CD. That's why you would need the symlink.

But don't you need permissions to /dev/scd0 when you burn?

hmmm... I have never changed the permissons on my scd0. Although, I might be root whenever I burn. I haven't done it in awhile. I'll have to try with a non-root user and see.

cpv204 · 06-11-2003, 10:46 AM

OK. The point is kind of moot since I've change the permissions anyway. Just thought that if you'd need to change them to burn, that would be in the HOWTO.

So...maybe you don't after all...

I got this same problem... my cdr and cdrom are the same drive. Prior to appending my lilo, I could read cds just fine... now, I'm able to burn, but I can't read.

Any suggestions?

*edit*

By the way, I get this when I try (after putting a newly burned cd in there... America's Army if you're curious)

Code:

Could not mount device.
The reported error was:
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)

So... anyone?

Here it is:

Code:

/dev/hda3        /                ext3        defaults         1   1
#/dev/cdr /mnt/cdr iso9660 noauto,owner,ro 0 0
/dev/cdrom       /mnt/cdrom       iso9660     noauto,owner,ro  0   0
/dev/scd0 /mnt/scd0 iso9660 noauto,users 0 0
/dev/scd1 /mnt/scd1 iso9660 noauto,users 0 0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0

Although it didn't used to have the /dev/scd0 or /dev/scd1, and the /dev/cdrom wasn't commented... I was just kinda trying random shit, hoping it would work...
