Hello, Right now I use Time Machine with an external hard drive. However, I'd like to purchase a 2.5" HDD with the same specifications as the one inside my Macbook Pro, place it in an external enclosure and clone my internal HDD using SupderDuper or Carbon Copy. In the event of an internal HDD failure, I could literally just swap in the other drive from the external enclosure and be all set. In your own opinion, which is better for doing this, SuperDuper or Carbon Copy? They both seem to do the same thing. Also, how well does using one of these programs go? If I ever need to replace the HDD with the cloned one, will everything work exactly like the original? Thank you for any help.
