How to clone a Windows HDD on a Mac?

My neighbours old Dell has died and I need to clone his old Windows HD on my Macbook, so when he gets a new PC I can copy it back to the new drive. Is it possible to clone an external windows HDD using my Macbook?

I have a HDD caddy
His old drive
A spare external USB backup drive
My Macbook

Forget it, I found a solution. Thanks for the pointers.
