In the middle of my most recent backup - my computer's hard drive crashed. The backup did not complete and so it was not restored to a bootable state. I was running a smart update so the information from the previous backup is still on my external drive.
I just got a new hard drive in my machine.
What is the best way to recover this data? If i copy the external drive onto my new hard drive using Super Duper will it screw up the new internal drive's "bootability" - this is obviously the drive that needs to run the computer.

Please help asap.
Thank you!
