NT file system mounting

I have a dual boot system. I am trying to mount an NT file system.
My NT file systems are NTFS.

I have tried the following, with the following results...

[root@polaris /root]# mount -t vfat /dev/hda4 /mnt/msd/c
mount: wrong fs type, bad option, bad superblock on /dev/hda4,
       or too many mounted file systems
       (aren't you trying to mount an extended partition,
       instead of some logical partition inside?)

[root@polaris /root]# mount -t vfat -v /dev/hda3 /mnt/msd/c
mount: wrong fs type, bad option, bad superblock on /dev/hda3,
       or too many mounted file systems
       (aren't you trying to mount an extended partition,
       instead of some logical partition inside?)

Any thoughts???


Thanks in advance for your help.
