So let's see I went back into the beginning of the thread and reread everything. Here is the sum: You have an internal CDRW (AOPEN CD-RW CRW5232 1.03 20031013) that is recognized by the kernel (that is good news) that when you mount valid CDs on it they mount no problem (since in earlier posts you fixed the little typo in your /etc/fstab). The only problem is that when you try to burn things with 'cdrecord' you can't get exclusive access on the drive even though you are using k3b or cdrecord as root. cdrecord -scanbus dev=ATAPI recognizes your CDRW correctly but still you can't get exclusive access on it. So the only thing that I have in mind is try to remove your CF Card Reader and then run /sbin/lsmod and post the results. Afterwards try to put an empty or CDRW cd in your CD drive and give something like say cdrecord -v gracetime=2 dev=ATAPI:0,0,0 -dao -data <some file here> and see what happens. Does it work now?
