I do not wish to be disrespectful to the author, but he fails to comprehend that it is not possible to eliminate error messages. There are rules that one needs to follow in order for things to work, and that is not because the developer is evil, it is because of inherent limitations. In this particular example, the error message seems stellar, and properly explained. Personally I would be grateful of not receiving a message that says "ERR_CANT_WRITE_DISK".
