Mount NTFS partition

[Fedora List]

Hi list

I'm trying to mount an NTFS partition.
FC1 on hda and Winnie XP Pro (NTFS) on hdb.
I've RPM'ed the correct kernel-ntfs rpm.
cat /proc/filesystems reflects ntfs available.
I've created /mnt/hdb1
When trying to mount hdb1 error message:

...not a valid block device

I've run almost all conceivable combinations and permutations of mount
-auto etc

Is there anything I haven't done?

TIA
