I just bought a brand new camera with dual slot. So with the new camera I thought I go and update my SD cards and got the 128gb version twice.
Went out tonight to test my new camera and used both new cards. I just got home and put them in my card reader (tested it on 2 different ones) and both cards are unreadable. I get the error code "The file or directory is corrupted and unreadable."
I spent hours!!! outdoors testing the cameras and now I ended up with no pictures on 2 brand new cards!
