I currently have a 4TB My Book. I have previously used it to back up data on my PC laptop. Unfortunately, my house was broken into and my laptop was stolen - thankfully, my external hard drive was left untouched.
I have the opportunity to purchase a MacBook that is far nicer than what I could get with a PC of the same price. Obviously, this poses a problem for my external hard drive which has been formatted to a PC. How can I convert My Book without losing all my data? Will I have to have access to a secondary hard drive? If so, should this hard drive be optimized for Mac or PC, and should I complete the process on Mac or PC?
