Ah yeah - OK. On my system drive, there is also a second partition. But my setup uses StableBit drivepool - basically, I use the partition as a 'quarentined' zone from my drive pool. The pool sits on the three other drives. Errr... so - you could just leave the partition on your system disk blank, or use it for things like server software downloads etc. Basically nothing that has regular read/write. Then StableBit will pool your other drives. In short - don't sweat it an dive in. So, looks like: C: and D: being on the same physical drive, and E, G and I being the pool drives.
