This is not good, there is nothing that can be done to retrieve your data by any standard method. If it was a problem with the memory component, there would be hope. But, the fault you are describing here is with the controller. Even with the specialist gear I use, this sort of fault has only a 50/50 chance, or less. Sorry to tell you this.
