救急：AS4系统挂载不了光驱怎么办~~？？？

草原之豹

我的系统内核是2.6,在终端下输入#cd /mnt #mkdir cdrom  #mount /dev/cdrom /mnt/cdrom之后回车，却出现下面的情况：
[root@localhost cdrom]# mount /dev/cdrom /mnt/cdrom
/dev/cdrom: 输入/输出错误
mount: block device /dev/cdrom is write-protected, mounting read-only
/dev/cdrom: 输入/输出错误
mount: /dev/cdrom: can't read superblock


我再试了一下输入#mount -t iso9660 /dev/cdrom /mnt/cdrom之后显示：
[root@localhost cdrom]# mount -t iso9660 /dev/cdrom /mnt/cdrom
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

我再直接输入：#mount /mnt/cdrom之后，显示的内容和上面一样：
[root@localhost cdrom]# mount /mnt/cdrom
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

没办法，再试了输入：[root@localhost cdrom]# mount /dev/hdc /mnt/cdrom
mount: special device /dev/hdc does not exist

却出现同样不能挂载的问题，请教各位坛友高手，能不能帮我解决一下问题啊，，我想用光驱，应该怎么办好呢，谢谢各位！！！！~~~~

/dev/cdrom: 输入/输出错误
mount: /dev/cdrom: can't read superblock

说明：
1.光盘问题
2.光驱问题

换一张光盘，也许就是OK的

zongyongchun

mount: special device /dev/hdc does not exist

这个有点可疑哦，你的光驱不被识别为IDE光驱

是哦，大哥，你说的没错，我换了碟就可以了，我原先用的是CD碟，为什么不行呢？？？
