Model-specific
What is true of this model and not of its siblings
- Cause not stated
- Nintendo's article gives steps, not a cause.
- Memory card
- Compatibility is part of the fix.
- Why updates and cards go together
- A system update unpacks data to the console's storage and, on some setups, to the memory card, so removing a card halfway through can leave partial files that later show as an error. Nintendo tells you to keep the card inserted during updates for that reason. After the update, restart the console once so that every service loads the new files.
- Compatibility of cards
- The Switch 2 accepts the faster microSD Express type, while the original Switch takes ordinary microSD, microSDHC and microSDXC cards. A card that suits one console may not suit the other, and an old card that is slow or worn can cause read errors even when it is the right type. Testing the card in a computer, or with another card in the console, shows whether the card or the console is the cause.
- When to go further
- If the error continues after a clean update and a known-good card, Nintendo's next step is service, and the article gives no further home fix. Back up what you can, with cloud saves if you have Nintendo Switch Online, before you send the console in.
