fstab & ntfs/fat32 partition

[MOPO3]

Hello,
I am trying to mount WinXP partition on my Fedora FC2, but when I wrote in
fstab the following line :
 /dev/hda1 /mnt/win_c ntfs iocharset=iso8859-1 0 0
then after system restart, on booting I saw an error/ somthing like this :
unknown format ntfs :/ I tried
 /dev/hda1 /mnt/win_c fat32 iocharset=iso8859-1 0 0
then I saw the same error :/

Tell me please, how can I do this ?
