I'm currently working with Edgy but you can use the same solution:
in the web search for ntfs-3g and fuse and you'll find the repository from which you can simply
apt-get ntfs-3g fuse
After that you can edit your fstab adding
/dev/hda1 /media/windows/ ntfs-3g user,users,auto 0 0
if you type mount you'll find a rw file system of fuse type which is your ntfs partition.
