How to slave a new WD for cloning with a laptop?

A friend asked me to fix his HP dv2715nr notebook.  Turns out the original HDD is going bad.  I stuck a used 320GB HDD into the laptop, and I’m reinstalling Vista using genuine HP recovery discs.  Which are horrendously slow, BTW - it’s been going for over 4 hours now and still not done. 

I’d like to clone the new Vista install from the used HDD to a brand new 500GB+ WD Blue.  My question is this - how do you use the Acronis software when you’re cloning a laptop? 

I’ve got a dock - can I use that?

Yes, you can use a USB dock to clone the internal hard drive.
