debian:~# mount /dev/hdd /mnt/cdrom2
/dev/hdd: 输入/输出错误
mount: block device /dev/hdd is write-protected, mounting read-only
/dev/hdd: 输入/输出错误
mount: you must specify the filesystem type

debian:~# mount -t vfat /dev/hdd /mnt/cdrom2
mount: block device /dev/hdd is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdd,
or too many mounted file systems

debian:~# mount -t ntfs /dev/hdd /mnt/cdrom2

CD-ROM的话
mount -t iso9660 /dev/hdd /mnt/cdrom2
DVD-ROM的话
mount -t udf /dev/hdd /mnt/cdrom2

另外，有可能是你的光驱读不动你的光盘（盘片不好）。
