A Big Thank-you, and how long should an inital back-up take?

Woohoo, it's finally finished, after just over 27 hours!!

Trouble is I've tried selecting the clone as the start-up disk just to check that it has worked OK but when I click restart within the start-up disk pane of System Preferences I just get a spinning beachball for a while followed by a 'boink' noise and then nothing else, it doesn't restart... I had assumed it would simply restart from the clone albeit slowly over the USB 1.1 connection?
