照着做也加载错误,求原因?

[root@linux /]# fdisk -l

[root@linux /]# mount -o rw -t vfat /dev/hdc1 /mnt/c codepage=936 iocharset=cp936
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 .
我用mount /dev/hdc1 /mnt/c 可以正确加载.
大家帮我看一下原因!!!

编码前也要加-o 参数的。比如像-o iocharset=gb2312

# mount  -t vfat /dev/hdc1 /mnt/c -o iocharset=cp936
