I have a Western Digital 250gb Scorpio drive in my Rocstor external hard drive, currently used by Time Machine. Is it possible to remove the drive from the case, and put it in my 'Book? Could I go out and buy a 1tb hard drive, and put it in the case? What would be my best way of coping data if the Time Machine backup is on the now internal hard drive? I have other a bunch of movies and T.V. shows on the drive, as well.
