My internal hard drive is 750 GB, of which about 180 GB is free. One more question: I've backed up some files on my new external drive - about 200 GB in several folders. I've done that with Carbon Copy Cloner before.Īnyway, that's my main question - can one boot up a MacBook Pro on a virtual clone created by Time Machine instead of using the internal hard drive? If so, how do you access it? I think I recall having to hold down a key (Option?) while the computer is booting up, which forces it to give you a choice of hard drives. I later realized that I might be able to boot up with my external drive and work with my cloned hard drive if my internal hard drive.

It's one of the new models that don't need a power cord you just connect it to your computer.Īnyway, a guy at the Genius Bar told me that I can use Time Machine to create a virtual clone on an external drive. I haven't backed up my data for a while, so I bought a new 1 Terabyte Seagate Drive for Mac.

I just learned that my hard drive is failing.
