Still in the SX50 test mode and I have a question

I shot a couple junk shots today with both RAW and JPG and then formatted the SD card.  None of my free recovery programs would recorver the RAW files but they all got the JPGs.  So does anyone know of a recovery program (I prefer FREE) that will recover SX50 RAW files from formatted cards?  I always like to have a safety net just in case :0)
