I FTP the files from my XBOX to my PC and put everything in a folder. Then I run GNUGDFImage on the folder to create an ISO files. This normally works for most games, but with a couple of games that I had, I does not. For some reason, after the image is created, I use an ISO reader to browse the files contained in the image. The very last folder is always blank and contains no files. I do not know why my Imaging utility keeps ignoring these files and never including them in the image.
Whoever knows what is going on please let me know if you have any suggestions.
