You'll never gat any partition to see another partition ever, no matter what you try. Paritions just don't have that capability. What you need is a third party utility that enables your operating system to access ext3 partitions. It is going to be much easier finding support in linux for ntfs than vice versa.
A linux ext3 partition CAN see an NTFS, all you have to do is mount it. Unfortunately, an NTFS can't see an ext3, unless there are 3rd party programs out there that im unaware of, but that's what these forums are for right?
