Nintendo Switch Error Code 2002-4517 — What It Means & How to Fix It

What Does This Error Mean?

The 2002-4517 error means your Nintendo Switch cannot read the microSD card properly. The card may be corrupted, improperly inserted, or incompatible with the Switch. This error prevents you from accessing any games or data stored on the microSD card.

Affected Models

Nintendo Switch
Nintendo Switch OLED
Nintendo Switch Lite

Common Causes

The microSD card is not inserted properly or has come loose from the slot
The microSD card has become corrupted due to improper removal or a power interruption
The microSD card is counterfeit or low-quality and cannot handle the Switch's read speeds
The microSD card slot on the Switch has dust or debris preventing a good connection
The microSD card has reached the end of its lifespan after heavy use

How to Fix It

Turn off your Switch completely. Hold the power button for 3 seconds, then select Power Options > Turn Off. Do not just put it in sleep mode.

Never remove the microSD card while the Switch is on or in sleep mode. This can corrupt the card.
Open the microSD card slot (on the back of the Switch, behind the kickstand on the original model). Remove the card, wait 10 seconds, then reinsert it firmly until it clicks.

Make sure the card is oriented correctly with the label facing away from the console.
Turn the Switch back on and check if the card is recognized. Go to System Settings > Data Management. Your microSD card should appear with its storage amount.

If it does not appear, the card may be corrupted or the slot may have an issue.
If the card is not recognized, try formatting it. Go to System Settings > System > Formatting Options > Format microSD Card.

Formatting erases everything on the card. Games can be redownloaded from the eShop, but screenshots and some save data may be lost.
If formatting does not work, test with a different microSD card. Use a known-good card from a reputable brand like SanDisk, Samsung, or Kingston.

If a different card works fine, the original card is defective. If no cards work, the Switch's card slot may be damaged.

When to Call a Professional

If the microSD card slot itself is damaged (bent pins or physical damage), the Switch needs professional repair. Nintendo offers repairs through their support website at nintendo.com/repair. Slot repairs typically cost $50 to $80 depending on your warranty status.

Frequently Asked Questions

What size microSD card does the Nintendo Switch support?

The Switch supports microSD, microSDHC, and microSDXC cards up to 2 TB. For most users, a 128 GB or 256 GB card provides a good balance of space and price. Always buy from a reputable retailer to avoid counterfeit cards.

How do I know if my microSD card is counterfeit?

Counterfeit cards often report a large capacity but actually have much less storage. They may work fine at first but start corrupting data once they fill up. Buying from official retailers and checking reviews helps avoid fakes.

Will I lose my game saves if I format the microSD card?

Game saves on the Switch are stored in the console's internal memory, not on the microSD card. Formatting the card only erases downloaded games, updates, and screenshots stored on it. You can redownload any purchased games from the eShop after formatting.
