光驱挂载不了~

cooldidi

我的光驱为什么挂不上啊?
放入cd可以听到,当时换成windows系统盘就挂不上~
命令行下挂载,提示

[root@mdk cooldidi]# mount /dev/hdc /mnt/cdrom -t iso9660
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 systems
[root@mdk cooldidi]# mount /dev/cdrom /mnt/cdrom -t iso9660
mount: block device /dev/cdrom is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
       or too many mounted file systems
请问该如何做啊?
系统是
redhat 9.0
mdk10
fedora core 1

参数顺序不对吧。
应该是mount -t iso9660  /dev/cdrom /mnt/cdrom
