Gears of War 3. Burned truncated (ImgBurn). Burn verified (ImgBurn). Loads on 360 no problem. Plays from disc with no problem. Installs to HDD with no problem. Won't play from HDD, disc still spins. Same results with both Verbatim and Memorex. Is this normal for truncated (97%) games (since they are missing data)? Tonight I think I will install it from the retail disc, and see if it will run from the HDD using the truncated disc.
