Installing Debian on USB HDD

[Johnson, Chad]

Hi,
 
I just bought a USB harddrive and I want to install Debian on it. I have a base 
Debian installed on a miniCD, and when I boot to the Debian installer and I get 
to the partitioning part, my drive is not listed, so I can't partition my drive.
 
I'm just starting out with Linux, so I have a very limited knowledge. I'm a CS 
major, so I know a lot about computers, but not Linux.
 
How can I install Debian on my drive?
 
 
 
Thanks!
