You cannot mount even a conventional CD drive as a writable
cd9660 filesystem. Creating a cd9660 fs is normally a one hit
prossess in which the fs is created fully populated and can't
then normally be changed except on RW media by overwriting the
I don't know the device you are using but would expect that you
can write a populated cd9660 file system directly using cdrecord
(or perhaps burncd) without attempting to mount; just as you
would on a conventional ATAPI or SCSII CD drive.
