If you're a Windows user like me and you don't want to give up your NTFS partitions and still use Linux, there is a way! NTFS-3g is a driver that allows for read and write access to NTFS partitions without having to boot up Windows.
I was looking around on my OpenSUSE install and came across this guide for installing ntfs-3g (and fuse). It should work for Mandriva as well (I'll definitely be trying it as soon as 2007 final is released and post if it works there too).
Anyway, the guide is here.
