Basic / new user. I've tweaked commands, but mostly use GUI.
I hastily removed an SD card before ejecting.
I then inserted a different SD card, which is now corrupted in all systems and readers, including the original board mounted reader, camera and external USB reader.
What can I use / do to recover the photos from the second SD card?
My user level is that I am able to use the terminal for commands and most any GUI program. Any help is appreciated so I can recover valuable photos from an Opera photo shoot.
