Probably a higher disk speed... well it should happen with any system that spins a disk, I bet if you shook a PS3 you'd get the same damage too.
Well yes and no. You would definitely damage the disc in the PS3 (never a good idea to shake a disc drive while it's reading something), but I doubt it would be as bad as the 360's. A major part of the reason is because M$ (AKA Microsoft (which is still infinitely better than Apple)) was too cheap to install tiny little rubber bumpers in their consoles that would prevent disc drives from completely eating discs if they are bumped. And seeing as how the new "slim" consoles are much smaller than the old ones, I doubt that it has been fixed (the label on the console there was a pretty big tipoff too)...
Sorry to say this but you are *vulgarity*ed. But no worry do you have a warranty?
Huh, oh yeah no worries. That happened last New Year's Day. *Cues flashback transition effect and settles in for a long story telling session*
You see, initially when she jumped the disc was destroyed, but my older cousin (er yeah the brat is actually my 1st cousin once removed) payed me back for the game before they left. However, about five months later I started noticing that the disc drive wasn't always reading the discs. Over the next month it got worse and worse until eventually it wouldn't even detect that there was anything in the drive (never thought I'd miss the console saying that my Halo 3 was a malfunctioning DVD that much). So as you can imagine, I was pretty pissed off. Now I'd bought a service plan from Best Buy for my Xbox when I first got it, and had actually turned it in once before (RROD) and gotten a replacement, but as luck would have it, the plan expired the month before. Naturally this just made me even more pissed off, and I was about ready to punch a hole through the nearest wall when I found out. Luckily though, it turned out that my current system was still under the 1 year factory warranty.
So come the week before finals, I packed up my console and shipped it off to Mesquite, Texas to be "repaired" (all they really do is give you a refurbished console). Then, with absolutely perfect timing, I get "my console" back in the afternoon just after school ended! Needless to say, I stayed up all night playing Live.
*Cues return to real world transition*
Er, so yeah there's my exciting end of school story...
Anywho, recommence with the praise of Halo: Reach.
