Coming off a successful launch of its Xbox One gaming console, Microsoft has acknowledged that some of its users are having problems with the device’s disc drive. Users have reported on online shopping sites, social networks and the gaming-focused site Kotaku that the drive makes a cringe-worthy grinding noise when they insert a disc. Kotaku reports that it has received around 150 e-mails in two days from folks who are experiencing the problem; the review unit The Washington Post received had no such issue.

The firm confirmed in a statement Monday to The Post that it is aware of the problem, which is “affecting a very small number” of its customers, and that it is working to replace those units.

“We’re working directly with those affected to get a replacement console to them as soon as possible through our advance exchange program,” Microsoft said in a statement. “Customers have the option for us to send a replacement console right away without waiting until they have returned their old one. This means a customer only has to wait a matter of days, rather than weeks to get back up and running.”

Microsoft announced last week that its Xbox One sold 1 million units in its first 24 hours on sale.

It was the largest-ever release for the Xbox, Microsoft said in a statement late Friday, adding that the console is now sold out in a lot of locations and that the firm will be acting quickly to replenish store shelves. The Xbox One is Microsoft’s first console since 2005, and faces stiff competition from the PlayStation 4, which launched a week ahead of its rival and also reported 1 million in sales in the first 24 hours.

Sony’s launch was also a bit bumpy, with the firm reporting that some of its consumers — less than 1 percent, according to the company — were experiencing problems with its console. Users have reported that the console does not turn on or does not properly connect to television sets; Sony has since published a document offering suggestions to fix a variety of problems that have been reported to the company since the PS4’s launch.
