I have just completed updating my hdd today. This is how I did it. 1. Made sure game saves and trophies had been synced with ps cloud. 2. Using a 500GB external drive used the PS4 own backup program in settings. Showed 4 hrs to backup a full ps4 drive. 3. Whilst backing up I downloaded the full software V2.57 from Sony (785MB approx) to a usb drive. Need to create a couple of folers and place file there. 4. Backup finishes turn of ps4. Unplug cables then replaced drive takes 5 mins max. 5. Insert all cables and usb pendrive. Press and hold power button on ps4 to enter safe mode. 6. Select option 7 then wait for ps4 to restart. 7. Set up ps4 as you did initially but don't activate as primary device. 8. Plug in backup device and goto settings and restore. Follow instructions and it will take same amount of time to restore as it did to backup. 9. Once complete log in set as active primary device again check your settings. 10. Your good to go. No downloading anything. All games work. 2TB hdd working great.
