I tried Carbon Copy again, then rebooted holding Alt and was able to boot off the drive via USB.
I then put it in the computer, booted up to BEEP BEEP BEEP - silence - BEEP BEEP BEEP.
So I took the batter back out, knocked it around a bit, turned it back on, and now it works.
Ohhhh K.
So needless to say I'm keeping the original hard drive in safe storage, this does not seem dependable. Apple blows.
