Answer to "No power to the disc drive? Everything else fine? Unique issue. X1"I have the exact same problem and took the same steps except for multi reader and 360. I've had my console for about 2 years though and i also dont know what caused it. Heres something weird though. When you press on the front power ribon near where it connects to the console, it turns the console on and off and also makes the disc drive act like it has a disc halfway in it. It sucks it in and spins it, but touching the ribbon isn't very reliable as it takes many tries and sometimes turns off the xbox. Anyway I think the problem is with the ribbon that connects to the disc drive button, but I don't know how to fix it. I doubt you'll reply to this because this post is 2 years old but if you've fixed your priblem maybe you can help me.
