Question: The hard drive has all my games but it also has windows. I have windows installed on my SSD is that going to interfere with anything? Also how do i use the hard drive without formatting it ?
Answer:You don’t. At least not yet. I would not even begin to think about doing it for at least 3 months just to see what I actually need to retrieve from it.
You can delete the unnecessary folders once you sure they aren’t needed. Keep in mind that many of your game saves are in your Users folder. I suggest making a backup before experimenting so you have a way to recover the folder if needed.
