CD Burning Issues


I am running slack-current plus DLG, which has the lastest and greatest with kernel 2.6.11.11. I am trying to burn CDs but everytime I get errors.

When I try the built-in GNOME burner I get "Disc full" error. I have tried multiple brand new CDRs and the error remains the same. I have looked up the properties on the discs and they are empty.

When I use Graveman I get a "cannot access /usr/bin/mkisofs" error. mkisofs is there, in that same place.

Anyone else experiencing these issues? Ideas/advice?

Thanks.

First thought, make sure that you aren't using ide-scsi emulation. I think you are supposed to be able to use it if you like. but I KNOW that you can get it to work without it.

Second thought, is you are getting an error about /usr/bin/mkisofs, have you checked permissions? I didn't see if this was a root+users or just a users issue.

Final thought, are your permissions for your burner set correctly? Is it recognized properly?

I don't know what DLG is, but are you open to burning CDs from command line?

This is one of the first things that intrigued me about *nix. It is more efficient than using a GUI, and you can get verbose output to see what is actually happening. You can even use the -dummy switch and just try it to see what would happen if you actually burned a disc.

This is the command I use to burn iso images to my CD-RW
Code:
cdrecord -v -eject  dev=/dev/hdc /path/to/file.iso
You'll need to replace hdc with the device name of your burner.

If you want to just try one, issue
Code:
cdrecord -v -dummy -eject  dev=/dev/hdc /path/to/file.iso
and see what it outputs.

Now, for the kernels after 2.6.8.1, you can burn as user or root. If you burn as user, you might have buffer underruns if you don't have enough free memory. That is because the silly author of cdrecord has it turn BURN-Free off. I would suggest you run it as root just to be sure.

Here's the details of a test run using -dummy
Code:
mingdao@james:~/iso/KNOPPIX_V3.9-2005-05-27-EN$ su -c "cdrecord -v -dummy -eject  dev=/dev/hdc KNOPPIX_V3.9-2005-05-27-EN.iso"

So you can see that would make a successful burn, in less than 3 minutes.

If you use the CLI a little bit, I think you'll learn to like it.

I think that it is a permissions issue. I can burn CDs as root. But burning from the GUI (xcdroast) or the commandline both gave me errors regarding fixatinng the cd at the end. This is the first time I have had issues with this burner under kernel 2.4 and 2.6. DLG is dropline gnome. I have now removed it and restored KDE and slack-current. I had to run the dropline remove script. I then removed the left over 20 or so packages. I reinstalled the rest with slackpkg. Worked great. I will re-try burning with the new system.

Try a -dummy burn with the command I suggested. I don't like to run
as root, so I use the su -c "command" option. It works fine, because
cdrecord is in users $PATH. Other than that, I don't know what you
think could be the permissions problem.
