Hi wyattspoppa. Have a look at wii game manager,( i like it it's easy to use/understand.) You can then open one drives files select what you want then copy transfer convert them to your second 320gb drive. Just what you were wanting I guess!

Note for Jax, 1, have a look at earlier options available in thread discussion,
1a, SD + NTFS
1b, SD + WBFS
1c, Fat32 + NTFS
1d, Fat32 only
And so on so Many ways to achieve your goals. OPTIONS is what I was offering.
And thanks for your twopennyworth of advice.
