Can I upgrade from a 80gb to a larger hard drive?

Can I upgrade from a 80gb to a larger hard drive?
The hard drive on my Ipod 5th Generation late 2006 80gb seems to have quit. I'm thinking of trying to replace it, and was wondering if it is possible to install a larger drive and would it be advisable?

ANSWERS:

While Technically possible, the Low demand for these types of drives yield high costs and low availability, generally making it not cost effective to do so.
