Check out Xplorer360, a free program that allows you full access [read-write] to your xbox360 hard drive by hacking its way through the closed-source file system of the new game console by Microsoft.
From the Site:
The program allows you to browse the entire 360 and even lets you drag files from your original XBox over to the 360, which, as we know, used to be impossible. There is even a new site, 360gamesaves, where you can trade saved games with others.
