I was just wondering if there was a way of selecting what letter you want for drives you have?  I'm using XP and rather lost.  I remember being able to do it on Windows 98, but now I don't know.

Basically, what I want to do is make my main drive as C: (already done), my second hard drive as D: (currently E), and my CD drive as E: (currently D).

Any suggestions?  Thanks.
