That tells me right there that your CD-ROM is not being mounted. It's in the fstab,
so the system tries to mount it, but the mount fails.

And this is yet more evidence that it has not been mounted properly -- KFM is
showing the contents of the mount point (i.e., nothing =) ) because the drive
hasn't actually been mounted.

So your CD-R is being detected properly,

What it looks like to *me* right now is that you've tried to configure your CD-ROM
as a CD-R. You've got it set to use SCSI emulation, and for CD-ROMs this generally
isn't necessary. What I would like to know is what you did to make your CD-R work,
because I suspect you also did this for your CD-ROM (and you should not have).
We'll need to undo this.
If it says you've got a rw device, then... hmn... it's mis-identifying it (again, I
think that's because you've got it using SCSI emulation).
What's in your fstab? (please *attach* it, don' t paraphrase). Is this an existing
kernel, or have you compiled one?
