Hi RTL
Frankly I find your post confusing!
Q1 How are you exporting to an external drive?
Are you using the FCP media manager?
Q2 What have you moved the Project or the Event or both?
From reading your post I am guessing that you have only moved the project and not the Event.
The project is in a sense a child of the Event.
Files in the project will always reference back to the Event where they came from....
