不能正常使用cdrom!

sgga

我刚安装了RH9，在放CD时能正常播放，但却不能mount cdrom!!!
在mount -t iso9660 /dev/hdc /mnt/cdrom时显示：
mount: block device /dev/hdc is write-protected,mounting read-only
mount: wrong fs type,bad option,bad superblock on /dev/hdc,or too many mounted file system
请问该怎么办？请赐教！！！
/etc/fstab:
LABEL=/ / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda8 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0

音乐CD碟由于格式问题，在linux里无法mount上，但可以用CD播放程序播放

用mount -t iso9660 /dev/hdrom /mnt/cdrom试试看

显示：
mount: block device /dev/hdc is write-protected,mounting read-only
mount: wrong fs type,bad option,bad superblock on /dev/hdc,or too many mounted file system
说明你的/dev/hdc错了……
