You probably heard about the Xbox One disc drive problem that many users reported in the past few days, where inserting a game into the Blu-ray drive will start a grinding sound, making impossible to play any disc-based game. According to Microsoft only a small number of customers received a faulty console and the company not only is granting free Xbox One replacements, but also it is offering free game download codes (Dead Rising 3, Forza Motorsport 5, Ryse: Son of Rome, or Zoo Tycoon) to ease out the pain a bit to those affected.
All that said, apparently there is a quick fix for the grinding and knocking sound in the disc drive of Xbox One. According to a support forum a method came up that is believed it fixes the issue, many Xbox One owners have tried it and it seems to work. The fix is pretty simple, remove any disc from the drive, disconnect all the cables, making your the console is completely turned-off, flip the device upside down, and firmly (but gently) smack the console with the palm of your hands about three times. Then flip the device over, connect all the cables, turn it on and try the game one more time.
Apparently, this method works because there is gear inside of the disc drive of Xbox One that isn’t quite align, and smacking the console upside down, somehow, puts the gear in alignment, fixing the grinding sound.
Although, hitting your Xbox One isn’t the way to go and I don’t recommend, if you’re careful, you can keep playing games until you get your replacement from Microsoft.
