I do not yet own a Mac, but will be buying a MBP soon. Right now I have an old PC laptop with a small hard drive. A few years ago I bought an external hard drive to give me more space. I have my iTunes library on it as well as all my photos and some other stuff. The external drive is NTFS. 1. How can I (or can I) transfer my iTunes library over to the MBP? 2. What do I need to do to get the data from the NTSF external over to the MBP and then make the HDD usable on the MBP? 3. I understand that the first time I plug the external into the MBP, time machine will ask if I want to use that drive for backup. If I say no, can I designate it to use for backup at a later date (I am assuming yes, but I don't want to assume)? Does the drive need to be empty to use as backup or would I be able to use it for time machine with all the data that is currently on there?
