Move Exchange Store

Good day Everyone,

My Server has only 5 gigs left and is dropping quick. I think it's because we a getting a lot more emails now. I have Small Business Server 2000 which includes MS Exchange 2000 (all in one). I went ahead a purchase a Maxtor 500GB Network drive, so i can move all my data to that drive and give me more space on my server. it looks like exchange is taking 90% of my server with all those emails. How can i move my exchange data files to my new 500GB drive, and have all new emails stored on this new drive from now on?

Thanks Guys
