After I swapped my HDD

Now I cant save games.
When I save a game, it says "Wait dont turn off your Xbox" and then "Save Complete"
Then when I restart my xbox I cannot load.
Either the game doesnt show up or says the save game file is corrupted.
What can I do to fix this?

 

was the hard drive you installed on the compatibility list?
What did you use to format it?

 

Yeah it was compatable and I used xboxhdm from xbins to set it up and used UnleashX to format the G drive.
