linux - Wodim can't open SCSI driver in Debian Jessie?

I'm attempting to write an ISO image to a CD on Debian Jessie. I have the CD in the drive, and it appears that all of the symbolic links are pointing where they should be, and the kernel recognized my CD-RW drive. (Which is connected via IDE by the way)


I installed Wodim from the official Debian repository. With either wodim --devices or wodim -scanbus I receive...


wodim: No such file or directory.
Cannot open SCSI driver!
For possible targets try 'wodim --devices' or 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.
For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from
the wodim documentation.

Although I don't think it should make a difference, I'm doing this via remote SSH.


The error says specifically that I need to read README.ATAPI.setup. I would be more than happy to do that if I had any idea where that was. I did a Google search for that file, but only found questions on various forums about issues similar to mine. After finding this question I ran some test commands to see if I had the same problem.


lsmod | grep sr_mod yields...


sr_mod                 21568  0
cdrom 46828 1 sr_mod
scsi_mod 164132 4 sg,libata,sd_mod,sr_mod

lsmod | grep sg yields...


sg                     25573  0
scsi_mod 164132 4 sg,libata,sd_mod,sr_mod

ls -l /dev/sr0 yields...


brw-rw---- 1 root cdrom 11, 0 Mar 12 17:20 /dev/sr0

That article mentioned that /dev/cdrom should link to /dev/sr0. Results of ls -l /dev/cdrom are...


lrwxrwxrwx 1 root root 3 Mar 12 17:20 /dev/cdrom -> sr0

Running any of these commands as root with sudo, or with a root shell do not affect the outcomes of any of these commands. Furthermore telling Wodim what device to use with wodim dev=/dev/sr0 --scanbus yields the same results as not declaring the shell variable.


What's the issue?
