SD Card Not Showing up
SD card not showing up is one of the most common issues for both Mac and Windows users. The SD card is connected and then, nothing, looking like the SD card is not recognized by computer. Most of the time, it's caused by connection problems. Or else, the SD card might be dead.
If the SD card won't show up even after a reconnection and computer restart, you need to check if the SD card reader is working before confirming the SD card is damaged.
