Opensuse will not recognize external drive with blank cd-r

I am running Opensuse 11.1 on a HP dv2000. I have an external optical drive (LG part number GE20LU10). Opensuse will recognize it if there is a cd with anything on it but when I put in a blank CD-R to burn something it disappears in the device notifier and the KDE burning tool cannot find the drive either. I am still very new to Linux so I am proly just doing something stupid. Any help would be appreciated. Thanks in advance.
