First off this is very confusing and I have looked literally everywhere to find an answer to this but I can't.
I currently have a 2TB HDD (internal) in my old PS4 (PS4-1) . I want to use the 2TB HDD into my new PS4 Pro (PS4-2) as an external HDD. I have over 1TB of data in the 2TB drive so I cannot do a system transfer - because in the PS4 Pro theres a 1TB Internal drive, and it won't allow me to transfer to a spare 2TB external drive.
So I took the 2TB HDD out of PS4-1 and put it into PS4-2 via usb, but the data wouldn't show up from my 2TB HDD. It only asked me to format the drive but I didn't want to.
So let me make this clear - I would like to use my 2TB HDD with all my saved games from PS4-1, as an external for PS4-2. Very confusing process.
borrow another 2tb drive?
