Will the USB port on a 3TB My Cloud read the full partition on a 3TB My Passport HDD? I have both 2TB and 3TB My Passports. My current router, and no routers I can find, will read the 3TB drive. Router limitations that also seem to apply on USB NAS devices. I am looking at ordering a 3TB My Cloud, but need to make sure it will read/write to the entire 3TB of the My Passport (NFTS) for backup. I see a lot of write-ups on routers, NAS, etc that talk about adding USB drives, but none talk about limitations.
