how comfy are you with taking things apart?
you may be able to retreive the data your self.
if the tech at frys connected the external drive circuit card to their PC and it messed up, then the problem is with the circuit card, and maybe the Hard drive is ok.
but there are other ways to do this.
remove the drive from the enclosure.
use a gizmo like this (frys has them as well)

I have one and love it. you can connect to ANY type of bare hard drive, power it up and get the data.
if this wont work, then you need a data recovery specialist.
