We got a 360 for Christmas and I thought the drive was very noisy, Grinding and whirring very unlike a computer drive. Now noticed Forza 3 has a circular scratch. I've booked the 360 in for a repair but the man on the phone said it was impossible for it to be faulty and cause a scratch unless it was moved - which it hasn't. They will very kindly replace the disc - for £10 . It wasn't our fault. Is this typical of Microsoft? Anyone had this problem?
