2005-0006
Nintendo Nintendo Switch
Severity: ModerateWhat Does This Error Mean?
2005-0006 means the Nintendo Switch detected corrupted game data and cannot start the software. The game's installation files are damaged and need to be repaired or redownloaded. Your save data is usually not affected by this error.
Affected Models
- Nintendo Switch
- Nintendo Switch Lite
- Nintendo Switch OLED
Common Causes
- The game's installation files were corrupted during a failed or incomplete download
- The microSD card lost power during a write operation, corrupting game data stored on it
- The microSD card itself is failing and has introduced read errors into the game data
- The Nintendo Switch experienced an unexpected power loss while updating the game
- The game cartridge has become partially unreadable due to a worn or dirty contact
How to Fix It
-
Check the game's data. From the home screen, hold down the game icon and select Manage Software > Check for Corrupt Data. If corruption is found, the Switch will prompt you to redownload the affected data.
This built-in check targets only the affected parts of the game. It is faster than a full redownload if only a small portion of data is corrupted.
-
Delete and redownload the game. Hold down the game icon and select Manage Software > Delete Software. Then go to Nintendo eShop > your profile icon > Redownload and select the game.
A fresh download from Nintendo's servers guarantees you get a complete, uncorrupted copy of the game files.
-
Check the health of your microSD card. Power off the Switch, remove the microSD card, and insert it into a computer. Run a disk check tool (Windows: right-click the drive > Properties > Tools > Check). Replace the card if errors are found.
A failing microSD card is a common cause of repeated corruption errors. Replace it with a quality UHS-I or UHS-II rated card from a reputable brand.
-
Try moving the game to internal storage. If the game is stored on the microSD card, move it to the Switch's internal storage. Go to System Settings > Data Management > Move Data Between System / microSD Card.
If the error disappears after moving to internal storage, the microSD card was the source of the corruption.
-
Update the Switch system software. Go to System Settings > System > System Update. A system update can fix bugs that cause data to be read incorrectly, resolving false corruption detections.
Some 2005- errors are caused by software bugs rather than actual corrupted data. A system update may resolve the error without any data loss.
When to Call a Professional
If corruption errors appear across many different games and your microSD card tests as healthy, contact Nintendo Support at support.nintendo.com. Repeated, widespread corruption may indicate a problem with the Switch's internal storage chip.
Frequently Asked Questions
Will my save data be deleted if I delete a game to fix 2005-0006?
Usually no. Nintendo Switch saves game data separately from the game installation. Deleting the software does not delete save data stored in the Switch's internal memory. However, if saves are stored on the microSD card (rare), they could be at risk — back them up to the cloud via Nintendo Switch Online first.
How do I prevent 2005-0006 from happening in the future?
Always use the power button to properly shut down or sleep your Switch — never let it run out of battery while a game is saving or updating. Also use a quality microSD card from a reputable brand like SanDisk, Samsung, or Lexar. Keep your system software updated to prevent software-side corruption bugs.
Does 2005-0006 appear with game cartridges too, or only downloaded games?
It can appear with both. For cartridges, corrupted data usually means the cartridge has a physical fault — dirty or damaged pins. For downloaded games, corrupted data means the installation files are damaged. The fix is different: clean the cartridge for physical copies, or redownload for digital copies.
