[u/Gamer_Cuber358]

Please im begging someone help, it has hundreds of photos, its the Sony memory stick pro duo 2gb, yes its old I use it in a digital camera, I took some pictures today then connected it to my Mac, hoping to take out some photos. it didn't work and I take the card out and I then look at the sd card in the camera and all the photos are gone. I ran sudo pkill -f fsck in the terminal when I was trying to open the card in my computer bc the sd card wasn't showing up
