So heres the situation, I have a Hitachi 47d drive that I want flashed. I am easily able to get into Mode B and have it seen in My Computer. After that I restore the Hitachi 47d with iXtreme 1.4 using restore.bat in safe mode. The restore seems to go well. So once I have accomplished that, I go to flashix.bat and run it. I type in the drive letter, preferred read speed, and name of backup file and run the flash. Like the restore, the flash seems to go well and says 100% complete and I can shut off the system. So, I do that and test the Xbox 360 on my TV, I first use an original disc, and it works fine, HOWEVER, when I try a backup, the disc makes a "whirring" noise and it later says "Unplayable Disc". I have modded 3 other 360's in the past, including a Hitachi, but for some reason this 360 is stubborn. I don't know how to fix something that is not broken if you know what I mean. Anyway, if anybody knows of someway for me to fix this problem, that would be great. Thanks.
