I had just finished playing Gran Turismo 4 and saving it. I decided to see the memory card browser when I saw corrupted data and I couldn't find my GT4 data of course I panicked. I then when into the game and it told me the game data was corrupted. It then asked if I wanted to create a new save and overwrite the corrupted data but everytime the game tried to delete the corrupted data it said it failed to delete it. I then tried delete it manually on the browser but again it failed. Now the game wont let me play without first deleting the corrupted data. Please help what should I do. I had 65.0% complete on the game.
