Howdy folks! I have a current model 2tb Time Capsule and I would like to add-on a USB external Hard drive to the TC. Any issues with using a 4tb 4k sector drive with it? I did a quick google and searched here, but didn't come up with a definitive answer. I plan to use the main 2tb drive in the TC as my time machine backup target and use the external USB drive attached to it as my media storage for all the computers and devices in my home.
