I never had this problem before only the past couple of days. I have tried checking my usb for errors, used different usbs, opened up Horizon or 360 rev as an admin. everything and I am getting corrupt files. Here is what I am trying to do. Copy a save file from one USB to another. Everytime I do this with, for example, Dark souls 2 or Dungeon defenders, I get corrupt data. Here is what I am doing. I use horizon, extract to desktop, save it into USB#2, save, rehash resign. Put it back into the xbox, start the game, corrupt file... Has ANYONE at all had this issue before? The weird thing is this. I tried to copy Border Lands 2 and it worked. I am currently trying with other games but I never had this problem before.
