I was under the impression that when i set new partitions and wrote them too disc it was going to reformat my drive , and wipe everything from it. It says it will on the tutorial , and i definitely know it is installed i have run it it runs just fine.
Any thoughts on why this is?

My homebrew apps were all their still my gamesaves , and 1 of my profiles. I it just that it used up the first empty slots and hasn't hit the ones on my other partition yet? I am really confused by this , i would figure the 360 wouldn't see the drive after it was ext3 formatted.
