If you want to leave it NTFS & have both R/W access to it then you have no choice but to use MacFuse & NTFS-3G ( this is a prog & driver that needs to be used together, it will become clear once you look for MacFuse ). MacFuse & NTFS-3G is free but their is a paid prog that does the same thing called paragon
Sorry not sure about this one, hopefully someone else might ??
