Microsoft Replaces XBox's That Fail To Read XDG3 Disks.

Even with wide beta testing, Microsoft seem to have missed some units as some users are finding the new XDG3 disk could not be read in their system. One such user, Avery Penn found out and reported to Microsoft. Microsoft responded checked his system via XBox Live (?) and agreed on replacement. This is what he posted  on Redit;

Checking my e-mail earlier today, I found a rather interesting message from Xbox Customer Support, saying that a software update is stopping some Xbox 360s from reading game discs.

Saying they were able to detect this issue over Xbox Live, Microsoft went on to say that, after jumping through all the necessary hoops, they'd send me a brand new Xbox 360 S and a year's free Xbox Live. At this point, my jaw hit the floor.

 Then he went and checked with XBox support if the email was real!

Microsoft Europe is now pointing affected users to the support page to get sorted out. One way or another, affected owners can expect to be mollified by getting their Xbox 360s replaced with new 250GB Xbox 360S
