Some early Xbox One adopters have reported problems with their console failing to read optical discs.
Videos of the issue appeared online overnight following the console's midnight launch and appear to show faulty Blu-ray drives, with the console making a clicking noise after a disc is inserted and reportedly failing to install the game.
It isn't yet clear how common the issue may be. Microsoft has yet to formally acknowledge the fault.
Xbox One's hardware fault follows an issue experienced by a small number of PlayStation 4 users last week, which left affected users unable to use their console. Sony claims that less than 1 per cent of PS4 users experienced problems.
Xbox One launched across Europe, North America, Australia and New Zealand last night.
