USB reading as raw, trying to recover files

[AmandaPanda]

So my wedding photos were given to me on a USB drive and when i plugged it in windows told me I needed to format the disk. I have tried it on other computers and it does the same thing. When I tried to run it in command prompt it told me the files are raw. So currently I have downloaded TestDisk to try and recover files. However the program is not recognizing the drive (the computer does and assigns it a letter). Is there anything I can do to find my drive in TestDisk? Or anything I can do in general to try and recover my files?

Update I have now also tried Recuva and it says my file type cannot be determined
