I have a ms25 drive flashed with xtreme 5.1 where I used 'Make ms25 read as ms25.' Ok, the problem is that whenever I extract a disc using schtrom 3.1 and burn using clone cd, it will give me an error saying "The disc is unreadable" and then it suggests I do a couple of things like clean the disc and whatnot. I have also had the opportunity to try this on another ms25 xbox360 flashed the same way and it gives me the same error. Now when I extract using xbc 2.3 and burn using clone cd, it will work fine. I always use default settings in xbc and always use stealth xtreme 3.0 for schtrom. So far I have had 100 percent success rate with xbc, and 0 percent with schtrom. I have not heard anybody encountering this problem and I really dont understand it. Why do you think this is happening? I realize that I could leave it alone and just always use xbc, but I always like to figure things like this out because theres gotta be a reason.
