Xbox 360 USB Details

New xbox 360 update which has let you use usb drives as hard drives to store data on, many have been looking into it, here is some info:

Data0000 – System Information
Data0001 – Partition (XTAF) header
Data0002 to end – Directory Tree / File Data

To load a usb device, just merge all the data files and load the FATX partition at 20000000h. To save the partition back, just split the file like:
0h to 20000000h – Data0001
20000000h to 2005C000h – Data0002
2005C000h to end – Data0003/others

Me and Jizzabeez are too believe that for each GB a new data file is created but we are not sure so if anyone will confirm this please do.

I have made a application for File2Image and Image to file programs to manipulate the files, I am also going to be making this application open source so others can help improve it. I've been talking to Jizz nate and mojo to try and find out more about these files and a better program is in development.
