I have an SD card known to have about 200 files when I removed it from my MP3 player. When I put it in my PC to copy files I wanted, a message came up saying that there was a problem with the card, and the PC immediately trashed the directory, as best I could tell. When I put it back in the MP3 player, the player showed "Unsupported Card Format". I installed my licensed copy of Recuva on my Windows 10 desktop and ran it with the deep scan enabled, and it found only one file. I wonder wy Recuva didn't find more files. Any help to recover the card will be appreciated.
