At some point, many of you will encounter an issue with your SD cards not being able to be read.
If you are lucky, the cable has just come loose from the motherboard. If you are unlucky, the motherboard connector is damaged.
The main cause of a broken SD card connector on the motherboard is repeated insertion and ejection of the SD card.
There is a single screw that mounts the SD slot daughtercard to the motherboard. As that screw becomes loose, the board can wiggle, and that causes the cable connecting it to the motherboard to rub on the connector, damaging it.
To minimize this issue, where possible, try using the "Mount SD Card" option in Hekate rather than ejecting the SD card. That allows you to access the Switch's SD card on a PC through the USB connection.
If the motherboard connector is OK and you just need to reseat the cable, tighten the screw that secures the board to the motherboard while you have the switch open. It is the silver screw just to the left of the SD slot. A spot of hot glue to secure the board at another point or two would also prevent it wiggling.
