The iPod Classic was released in September 2007, so it's less than a year old and well within its guarantee period. Technically, you don't need a receipt, so take your faulty iPod into an Apple Store - there's a list here: http://www.apple.com/uk/retail/ - and book a meeting with the Genius Bar - it's best to book, here: http://www.apple.com/uk/retail/geniusbar/ - to get the player fixed or replaced.
