Microsoft has just released a new us based Microsoft connect beta testing for Xbox 360 owners to test a new type of disk format. Rumors from euro gamer is being said that it adds a gigabyte of space extra on the disk. Users who get accepted receive a free copy of halo reach. We can bet that this isn't just a generous gift on Microsoft's part - more likely it is a disc pressed using the new format, and Microsoft is looking for data on performance on as many different systems as it can. There is no one standard Xbox 360 DVD drive: the platform holder has used drives from Samsung, Hitachi, Benq and Liteon across the console's five year history.
