Please excuse me if this is already a known and documented issue, but I was unable to find anything by searching the forum, so I'd like to know for sure.
I have found that the disc version of Resident Evil 5 apparently cannot be recognized by the Xbox 360 S model for some reason. I never had any problem with it on the original "fat" Xbox 360 model, but when I try to install or play it on an S model, I get an "unrecognized disc" error 03-80-00.
I have tested this on two different Xbox 360s of each model. Both of the original-configuration models are able to read and play the disc without any problems. Both of the S models get the same read error. One of those had no USB or storage units attached at the time.
The disc itself is spotless but I have tried running it through a professional-grade CD buffer anyway; no effect. Clearing my Xbox 360's system cache had no effect either.
I have only experienced this problem with this one, single game (Resident Evil 5). My Xbox 360 S reads every one of my other 40 Xbox 360 discs without any problems whatsoever. This leads me to wonder if there is a known issue with this game. Can anyone confirm this?
