Adding Another HDD

Hello,

I have windows 2000 installed on my computer.
Samsung HDD 16.02 GB.
I have installed windows 2000 on D:\ and it is full. I want to add another HDD to the computer of 20 GB. I want my existing operating system which is on D:\ to be shifted to new HDD (E:\).
How to do that… ? As I want to use entore 20 GB new HDD for win2000 without reinstalling it on new drive.
Thanks
