这是怎么了啊，我怎么就是挂载不上啊

谁来帮我看看啊，我想挂载4。1第二张盘。怎么不好用啊，看看这打的命令对吗，怎么会出来这么多提示！
[root@song root]# mount -t iso9660 -o loop/WinD/RedFlag-4-tool.iso/mnt/VirtualCDRom
Usage: mount -V : print version
mount -h : print this help
mount : list mounted filesystems
mount -l : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
mount -a [-t|-O] ... : mount all stuff from /etc/fstab
mount device : mount device at the known place
mount directory : mount known device here
mount -t type dev dir : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
mount --bind olddir newdir
or move a subtree:
mount --move olddir newdir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using -L label or by uuid, using -U uuid .
Other options: [-nfFrsvw] [-o options].
For many more details, say man 8 mount .
