Not really sure what the F drive is. I don't know how big it is. When I first open the file manager, it says Err: 1005 to the far right of F and when I select F, it switches to Err: 3. I am not sure what is going wrong. I watch a lot of movies on my box but have never had any problems with games.
Oops, forgot the rest of your post. I don't have a G drive. I have a C, D, E, F, X, Y, and Z. I have been using my modded box for about 3 and a half years. Again, I am not really sure what the F drive does so I don't know if I have been using it or not. This is the first time I have seen this error.
