I am going to be fedexing my Mac Pro tower from Vancouver to New York. I have the original box and I am sure that will be strong enough to protect the computer seeing as that is what it was shipped in. I am wondering if I will need to take the hard drives out of the computer to be extra safe? What are the chances that the drives will be damaged during shipping? I will of course have everything backed up on external drives that I will be carrying on the plane. Any advice is much appreciated!
