Well, this isn't just happening to me...found out it was happening to my friend too.
Basically, we eject the disk, the power button flashes for about 5-10 seconds, then the disc drive closes, and gets stuck.
We then have to move our xboxs around and try to get the drive to open.
Anyone else having this problem? Although a solution or explanation would be nice.
If its a new model Xbox look for a local repair shop, they pull the drives and replace them with working ones all the time, i have one locally that does it for 50 bucks.
