CD-Burner

[ferreter]

Hello all,

I installed knoppix to my HD via knoppix-installer. I set up the Nvidia drivers, get netoworking going, and upgraded my kernel to 2.4.21. But when I try to use K3b to burn a CD the drop down control for selecting the device is empty. Am I missing something here?

Thanks.

Ok, here's the deal. I can play a music CD from cdrom0 but can't seem to mount it in kde to display data CDs. I can mount and view CD's in my CD-RW but cannot burn CDs to it. wtf? Now I had to manually create the CD-RW icon on the desktop (right click, new, CD-ROM), does that have anything to do with my issues?

Thanks again.

First you'll need to configure k3b. Here is a post about it. Secondly if you've done the k3b setup your /etc/fstab file is probably hosed. If you could post it please. Also post the output of cdrecord -scanbus. Since you have a cdburner in your system Linux is using SCSI emulation to access your drives. Therefor they will be listed on the SCSI bus. Try this:

ls -al /dev/cdrom It should be a symbolic link to one of your drives. If it is a symlink to the wrong drive then it's not going to work. Post some details and we can go from there.

In K3b I attempt to add the /dev/cdrom1 device (as it correctly points to scd1) but it states that no device was found.

Thanks for your assistance.

Change the /dev/cdrom1 to /dev/scd1 in the /etc/fstab and it should work fine you may want to make sure that the mount point /cdrom1 actually exists I usually use mkdir burner as root in the / directory and then use this for a mount point eg. /dev/scd1 /burner iso9660 ....

I did this, but still k3b has my burner listed under the reader section of the devices rather than the writer section and quite obviously will not burn anything. I changed the fstab entry to not be ro but rather rw as well if that makes a difference.

As for the other odd issue, I was able to setup a new icon in my desktop to allow a right-click mount option where on the other icon it only gives me the option to play the CD. Can I not have both functionalities for the CD-ROM in one icon (both audio and data)?

Does not suprise me K3b seems to have many problems you may want to try installing XCDRoast the few times that I have used it, it worked without problems. If you want to test if your burner is working you can from the command line cdrecord -v -dummy -eject speed=4 dev=0,1,0 file.name which would run a test burn at 4x speed with the file you choose. Also you do not need the rw option in the /etc/fstab.

Never knew the audio option existed I usually use the command line to access CD's so I can't be much help there.

I had the same problem when I upgraded cdrecord etc a while back.

IIRC
- Under K3B the writer shows up only as a reader.
- Works if logged in as root
- Even if you are listed as a user in K3B setup it still doesn't work

It was a while ago so bear with me as I try to remember........................
I think it had something to do with permissions. Something was changed
when the newer version was installed!?

Let me know if it runs as root.

Good Luck

Most Linux apps will try to use /dev/cdroom by default. If this is the case with k3b then you just need to symlink /dev/cdromk to your burner. It's easy:

As root...
rm -f /dev/cdrom
ln -s /dev/scd1 /dev/cdrom

That should have made a symbolic link from /dev/scd1 (your cd burner) to /dev/cdrom. How do you find out?

ls -al /dev/cdrom
lrwxrwxrwx 1 root root 9 Aug 3 06:53 /dev/cdrom -> /dev/scd1

If your output looks like the above then you were successful. Also make sure you have selected the proper cdrdao driver in k3b configure. Usually generic-mmc will work.

Desktop icons? Hmmmm heard of em but that's about it. It's just easier to mount them manually, besides do you actually ever see your desktop? I don't but that's just me.
