How do I get content from an external HDD to my co-star? I have a Seagate 3TB external with a lot of music and video that I would love to have access to. Specifically, I've got every known episode of Doctor Who and would love to be able to view them on the "big screen." Is this something that can be done with the co-star. I tried connecting it via the usb and all I get is a notice, "Preparing USB storage "Seagate Backup Plus Drive." Any help is appreciated.
