Finally picked up an external HDD for my PS4. (WD 4 TB passport) since this is powered through the USB port, what's everyone doing for powering down their PS4? I typically put the PS4 into rest mode, so do I leave the the USB ports always powered? Prob not the most ideal but I read where some people got had gottened error messages about the drive was not powered down correctly doing different options. I figured I could safely disconnect the HDD before rest mode, but then game updates won't install I would assume. Thanks
