Games disappeared from library after a crash

So I was in a Halo: Reach custom game last night with a bunch of people. Friends think this is an HDD failure and that I should delete my profile and items but I wanna see if there's another way before doing that. Anyway, back to the subject!

I don't know if this messes things up or not, so forgive me for being ignorant if I was here, but when my game froze I thought it would be a good idea to unplug my power supply because pressing the power button doesn't seem to work right away, and I probably
should have waited. Anyhow, when I plugged it back in and got online, all my games were gone. I checked my storage, my hard drive, and it is completely empty. My memory unit has most of those games, but they still don't show up in the "my games" library. Everything
is in my download history, but I can't download them back, it doesn't give an error it just says that it can't download. When I try to play a game on disc though, it tries to update and fails, showing a status code: 4467 - 0000 - D080 - 0200 - 8007 - 0003.
I'm honestly not sure what to do now, what would be my best bet, and is it possible to save my games with those save files intact? Thank you so much for reading and trying to help me out here!

Game disappeared from library

I bought Dead Space 2 on may and I used to play in on my xbox one via backwards compatibility . Today I went to my library to install the game and it was gone. I went to the store and it was like I never had bought, but I certainly did, it is registred on
my history and I have the bill of the credit card that I used to buy it. So what's going on?

 

Forza Horizon 3 Disappeared from library

As a start to a problem on the FH3 store page the button says "Manage" instead of "Install".

The first time i clicked on "manage" i got redirected to My library and the game was listed, i clicked on the download symbol and gave me an error window saying "Try again later Something happen on our end"

After a while it simply disappeared from the library, i checked the hidden apps it´s just not on the library, and the game page still says "manage" on the button. any help?

 

Heya CommanderKailyn.

Really sorry to hear about the storage trouble you're having. Unfortunately it's definitely sounding like a storage failure. Do you possibly have a USB drive you can try and copy the save files from to keep them intact before trying a factory reset of your
HDD?
