Windows 7: Raid 0, what options are there for the rest of the space?

Hello,

I have recently changed hardware and also raid controller. This meant I had to move all my data to a "normal" hdd, because I had to rebuild the array. So I figured I would only make new array as large as the OS would need and then have the rest as jbob or something. But when I make the array, raid 0 over 2 hdd's, I can't see the remaining unpartitioned space in windows disk manager. I tried to make jbob's from the raid controller but it wants min. two drives and when I did that it said something about there already was a logical disk. Propably meant the raid 0..

So is it not possible to have a raid 0 on a part of two hdd's and use the rest of the space "outside" a raid setup, so I don't have to move the data next time?

Thanks..
