SD card

micro SD card error. Took drone video footage, then put it into my SD reader. I looked at some footage, then left it in the reader and shut down the PC. The next day, the reader said that I needed to format the card. I have been using TestDisk to try to recover or fix the card, but not having any luck. I could just reformat the card, but I want to save footage if possible. Any suggestions?
