I know, its nothing new, however not many people know about it. Personally I don’t have that many NTFS external drives, mostly because I knew it would cause issues with Mac and Linux/Unix. So instead I use to format most of my external drives as Fat32. However I would have to make a couple of partitions manually because Windows 2000/XP actually limited you from creating partitions large than 32/64GB. You can get the specifics because this covers more than this article at WikiPedia:
Don’t worry about Fat32, partition your drives as NTFS and make them as large as you want. You can now using them on Mac OSX using MacFuse and NTFS-3g from Tuxera.

NTFS-3G from Tuxera – http://macntfs-3g.blogspot.com/
Install both and enjoy!
