Why can't I find game data with xplorer 360/ xsata?

I just got an xsata transfer cable for my xbox 360. I also have xplorer360 and Modio. I have windows 7 home premium. I hooked up my Xsata to my 60 gb hard drive. I then hooked up the xsata to my computer. Then I ran xplorer360 as administrator. I opened harddrive\memcard and got the three partitions. part. 0 had a folder an a file with A's and several symbols including trademarks. part. 2 had index, TDBX, and compatibility, which had more things like font and dash in it. part. 3 didn't have a thing. I think this means I only have xbox 360 data, not any of the game data. (Halo 3, Halo Wars, H.A.W.X., and a bunch of demos and originals.) I want to do things like mod halo 3 and bring film clips to my computer, but can't do that without the game files.
