Unsealed documents in a lawsuit over an Xbox 360 that repeatedly scratched a dude’s games reveal that Microsoft knew all about the problem, but rejected all three possible solutions prior to the 360′s launch.
Of course, this isn’t exactly shocking—Dean Takahashi revealed just how startlingly troubled the Xbox 360 was from the get-go. Hiro Umeno, a Microsoft program manager, said in a declaration about the disc-scratching problem that “This is … information that we as a team, optical disc drive team, knew about. When we first discovered the problem in September or October (2005), when we got a first report of disc movement, we knew this is what’s causing the problem.”
The solutions considered—and rejected—were to increase the magnetic field of the disc holder (could’ve interfered with the disc opening and closing), slowing the disc speed (could’ve increased load time) and to install small bumpers (too expensive, costing between $US35 million and $US75 million). Instead, they went with a warning in the manual not to move the console with the discs still inside, a warning that Microsoft itself thought was insufficient, according to an internal email. A consultant for the plaintiff notes that Sony and Nintendo “almost always incorporate the possibility that a console could be moved while a disc is rotating inside in the designs of their products.”
Moral of the story seems to be not to buy rev. A hardware from Microsoft, perhaps the only major company to not pass muster under our maxim it’s safer than ever to do so. [Seattle Tech Report via Xbox 360 Fanboy]

Tuesday, December 16, 2008 at 11:19 PMThis is not an exclusive 360 problem and applies to many DVD drives. Anyone who has taken a few a DVD drives apart will probably recognise the problem. Around the lens is a plastic surround which sits close to the disk as it spins. Some drives have a small rubber collar but most don’t. Moving a drive while it spins risks crashing the lens mechanism into disk. Not so much a problem for low speed drives but in high speed drives it can be nasty for the disk. Aside from being common sense, Microsofts warning is pretty reasonable and applies to just about any high speed drive not designed to be portable. I can’t imagine what bonehead would be deliberately moving a going 360 around but accidents happen. Usually the “scratching” looks worse than it is as it’s plastic on plastic and will polish off with Brasso or perspex polish.

When i contacted Xbox to tell them what had happened, they refused to replace the discs even though it was their faulty hardware that ruined them! So $200 worth of games rendered useless, and xbox knew about the problem the whole time.

There is no mystical design fault in the 360 drive. They are garden variety drives found in countless products and are even supplied from several different manufacturers. Get a 360 drive and take it apart and compare to a PC DVD drive. I personally have only ever seen one drive that exhibits non-movement related scratching and that was in a $1500 Denon DVD player. That was caused by the laser not focusing and driving the laser head into the disk trying to focus. I’m not saying you didn’t experience something similar but it would be a uniquely faulty drive not something affecting all 360s. Given there are 10 million+ 360s some probably have this problem.
After reading some of the posts last night I tried my own experiment and used an “Arcade unplugged” disk and deliberately tried to get the 360 (manufactured April 2006) to scratch it. I didn’t drop the 360 but no amount of twisting or shaking (within reason) induced any scratching at all.
