Xbox Doesn't Read Disks Anymore?

My xbox won't read any disk any more, I tried playing Black Ops 2 and just as I get into the main menu, it freezes or says "Disk Unreadable". I tried playing Minecraft which is downloaded to my Xbox, which I do not own a disk for, and it also said "Disk Unreadable". I don't know what is going on, I've cleaned the disks very much too and still nothing works. GTA 5 doesn't work, and neither does Cod Ghosts.

Minecraft for X-Box 360 or Dawnguard DLC for Skyrim?

So I have $20 I'm wanting to spend and I'm deciding on whether to get Minecraft or Dawnguard for Xbox360. I've had Skyrim since a few months after it was released and I really liked it but for awhile now I've not been able to get into Skyrim and just get bored of it. I've never gotten a Skyrim DLC either btw. On the other hand I really enjoy playing Minecraft and I have a few friends i could screw around with on it, online, as well as it's continuing to get add-ons to this day so there's a bit more to work with possibly. So. Do you guys think Dawnguard would be enough to get me back into Skyrim and not just be a waste of $20, or should I take a safer route with Minecraft and stick with something I'm somewhat certain I would enjoy? It'd be nice to hear opinions from those who have played or own both and to get answers with reasons, but any answer is appreciated. Thanks for taking the time to read and/or answer this.

I accidentally pressed b while updating a game on xbox 360?

The game is minecraft and at 75% done I sat on the controller and it pressed b and exited the update and went to homescreen! So I went to minecraft again and the loading screen looked really old, and then it said i needed an update so i updated. Then it didn't update at all! It showed all the old blocks I was already using!

I don't have the horse update, I'm stuck on the older verison.

Minecraft Xbox One vs PC?

I own both, I've had PC way before 360 and Xbox One. Anyway, how close is the content matched up to date with the Xbox One's content?

There aren't horses in the One version so they must be pretty far behind no?

Can you name a survival game for Xbox 360?

When I say survival, I mean this: not horror, no zombies, no supernatural anything. I want a game where I have no food, water, shelter (in the gameplay, not plot), and I have to get these things. No, I can't PC game. I would be satisfied with even an XBLIG.

No minecraft.
