I say software raid because that is a pretty tentative guess at what I actually want. I have two drives, both with stuff already on them which I want to combine. If they weren't full of stuff (data, not windows installation) I would use software raid to combine them into one big drive or make them into one partition. I could probably do this with some complicated reference system but really I just want to be able to keep saving things to X: without running out of space until both drives are full. Thanks in advance.
