OK Andy,
Let's start again; first of all, are you partitioning a new drive, or are you trying to partition one that contains your data?
Partitioning with data in place can be tricky. Before we start talking about how, can you first get into what it is exactly that you want to do, and why. That way we can give you the best advice on what you actually are trying to accomplish.
Looking forward to your reply,
TTFN
LGW
