You need to put something like this in your /etc/fstab:
/mnt/data /dev/hda5 ntfs defaults 0 0
.......
I think you r correct when you use simple ntfs driver......
but what I had used is fuse & ntfs-3g driver to mount my drive..........
I also mount it like this:::
n terminal
mount -t ntfs-3g /dev/hdb1 /mnt/cdrive
rather than.......
mount ntfs /dev/hdb1 /mnt/cdrive........
