Are SD/MMC cards the same as regular SD cards?

Useless SD cards or Useful SD cards?

• Hello, I have collected two utterly useless SD cards over the years. One that contains a demo for a treadmill we bought(iFit), and another for this wii package we bought(switch and carry). So i thought id use the SD cards for something better, like my camera, however, whenever I put either sd cards in my camera, I get a error message saying “card error” I have tried formatting the disk and I made sure the card was on read/write mode... these cards also do not work in my computer's built in SD card reader which is fine since it still works with my lexar SD card.... any suggestions?

• Answer:

  Are you sure that your camera can handle regular SD cards and doesn't required the newer SDHRC cards? I have a Nintendo switch and carry that I use in my camera, but that camera is 2-3 years old. Can you blow through the card error and get to the format command in the camera and format them there? (Sorry, wasn't clear if you were trying to format them from the camera or computer). You shouldn't format camera cards in a computer as it can easily initialize them into a format that cannot be read by the camera.
