Even my backup showed a Disc unreadable error the first time but it played fine since then. So the first step in solving the errors would be knowing that, 1: The Disc 1 content of the GTA5 is DRM free so there is no need to burn the 1st Disc rather it could be done by just copying the Content from the Disc1 ripped iso to the XBox 360 internal Hard drive( should also be true for external USB). The above mentioned step could be done by: a) First Using the tool "Xbox Image browser" extract the "Content" folder from the GTA 5 disc 1 iso to your PC hardrive. B) Now after extracting there would be 4 files inside the "\content\0000000000000000\545408A7\00000002" amount to 7.7 GB(2gb,2gb,2gb,1.7gb) to be precise. Please make sure you got all of them. c) The next step is to copy these files to you 360 hard drive using a USB flash drive. This could be done easily by using a 360 USB drive and connecting it to the PC and using a software called "horizon". i.) After the USB device is detected in Horizon, choose to inject file in the game folder and select the 4 file inside the \content\0000000000000000\545408A7\00000002 folder. Horizon will automatically create all needed folders for the game files to be detected by the XBOX you just need to inject those 4 files. d) After successfully injecting the files to the USB, now copy the files from the USB to the hard drive. It will take a long time depending upon your USB speed. So I guess, now all the DISC 1 problems should be solved, considering there was no burning involved it was simple copy an paste. I would like all of you to know that I did the same exact thing, and I burned the DISC 2 backup image with XGD3 and 100% verify. But I still somehow got the Disc Unreadable error when I started playing from the Disc 2. Solving Disc 2 problem: What worked for me was to install the disc to the hard drive or the USB drive, even after getting disc unreadable error the Disc 2 installed to the XBOX 360 100% without any errors and then when I started the game it ran pretty smoothly with no noise at all from the drive(should be because of the installation.) I don't know why I got the disc unreadable error while playing straight from disc 2 in the first place but it is now solved after installing the game to hard drive. So anyone facing problems playing the game should consider the steps mentioned above. Thanks to Akram for mentioning that DISC1 could be installed without burining.
