All of my game saves are gone

No sorry, it's a 120gb from Microsoft, my mistake. I have nothing 3rd party.

I suggest using ur cloud storage

In my view I know losing your saved history is quite bad countless hour's of playing saving up achievements just to be vanshined. However on the brighter side you could play all those game's again to gain back gamerscore and you'll have more hour's of fun
(if your ever bored just sitting playing online)

Hey, thank you for your answer. I am the only one who's using the Xbox, my girlfriend never uses it. I haven't posted it on the Forza forums because all my save games from all my games I've played are gone. So it probably is an issue with my Xbox or the
hard disk.

I have the same problem, I just spoke with Microsoft representative and he admitted that the data are gone. He wrote this: "If your Internal Hard Drive and not your External Hard Drive that's installed inside the console has the issue, it means that we can't
do anything to recover your saved games. But since your games is still on your account you can download it again on the console and play the game again. And I strongly suggest that you use a Standard Microsoft Hard drive for the storage for your games, saved
games and any other items. I do apologize for the inconvenience, I have tried to do my best and to pull all the options in my end. But you will need to play the games again, we can't recover the saved games for you. If we can do it, we already done it on your
first contact to us."
