I have got a problem which is quite frustrating recently. For my XBOX 360 games, my old dumps are 7.05GB (DOA 4, Moto GP 06 and 07 ...) and new ones are 7.29GB (Lost Planet, Rainbox six Vegas), I am not able to play 7.29GB dumps, the discs are still the same. XBOX360 says it is unrecognizable disc or dirty. Any reason? Xbox 360 drive is HL-GDR-3120L V47 version flashed with iXtreme1.2 Rev2 FW by FW flash toolbox 4.0. The drive I use to dump games are Samsung D-162C Kreon V0.81. And I use XBOX Backup Creator latest version which is 2.6 something (the new version does not require any installation). Have wasted so far 5 D5 discs. Please help guys. Thank you very much.
