What to Do:

1. Power off the console and remove the microSD card.
2. Verify that the microSD card is compatible with Nintendo Switch.
   • If the microSD card is not supported, replacing it with a supported type may resolve the problem.
3. Reinsert the microSD card and perform a system update.
   • The system version may not necessarily change after this update.
4. If the microSD card cannot be read on Nintendo Switch, try the following:
   • Format the microSD card.
   • Use a different microSD card.
   • Remove the microSD card and download directly to the console's system memory.

Situation Not Resolved:

If the error persists with multiple microSD cards, then the Nintendo Switch console will need to be repaired.

• For testing purposes, be sure to include one or more of the problematic microSD cards that were being used with the console.
