Save data is tied to each user account and is stored on the system memory.
If there are multiple user accounts on the console, verify that you are using the correct user.If a user account has been deleted, all save data associated to that user will also be deleted and cannot be recovered.
Start the game or software application and select your save file.
If the save file for a given user is missing, you will need to start your game progress again.
Remember to always save your progress correctly and close the software application before shutting down the console.
Verify if the issue is happening with other games or applications.
If possible, try starting a different game or application. Then attempt to save your progress.
If the game progress cannot be saved, or if an existing save file cannot be read, try initializing the console via maintenance mode without deleting the save data.
Situation Not Resolved: If the issue persists, the console will need to come in for repair. Be sure to include any problematic game cards, or indicate with which downloaded software this issue is occurring.
