My camera is a rather old DSLR which still uses CF cards. In order to get the images, I would take it out of the camera body, put it into a card reader and then transfer the images. Afterwards the card was inserted back into the camera body. This has worked fine for years, but one day the card reader would not work any more. I didn't understand, and just bought a new card reader. One day in 2016, the new card reader stopped working. I then looked into the card reader and saw that a pin was bent.
So I took a simple screwdriver and tried to fix the pin and bend it back.
