Microsoft has responded to reports that owners of its new Xbox One console are experiencing problems with the disc drive by offering a free download.Some users have said the drive makes very loud noises when they try to insert a disc and in some cases is not reading discs at all.Microsoft said only a very small number of users are affected.The Xbox One was launched on Friday and sold more than one million units in the first 24 hours.In a statement Microsoft said that those customers who had reported problems and were waiting for a replacement console would be provided "with a free digital download of one of the launch titles published by Microsoft studios."More than 150 people contacted Kotaku, a gaming news website, claiming their new consoles were faulty. Other users uploaded videos apparently showing the problem to the gaming forum NeoGAF.The Xbox One is the first new console from Microsoft in eight years and it broke all previous Xbox first-day sales records when it went on sale in the UK and 12 other countries last week.The company said it had now sold out at most retailers and it was working to replenish stock as fast as possible.
