microSD cards are generally reliable, but problems can occur. Here are the most common issues and how to resolve them.
Problem 1: Switch Does Not Recognize the Card
Possible causes and fixes:
- The card is not fully inserted → Remove and reinsert until it clicks
- The card is formatted incorrectly → Format to exFAT or FAT32 on a PC
- Dirty contacts → Clean the metal contacts with a soft cloth
- Faulty card → Test the card in another device. If it fails there too, replace it
Problem 2: Games Load Very Slowly
If game load times are noticeably longer than before, the card may be too slow. Check its speed class. Cards rated below U1 (or without any class marking) struggle with game data. 업그레이드 to a U3/A2 card for better 성능.
Problem 3: Data Corruption
Corruption can happen if the card is removed while the Switch is on, or if the card is near the end of its life. To prevent data loss:
- Always power off before removing the card
- Use Nintendo Switch Online cloud saves for critical save data
- Run chkdsk (PC) or First Aid (Mac) periodically to check for errors
If corruption occurs, connect the card to a PC and run chkdsk with the /f parameter to attempt repair.
Problem 4: Card Gets Hot
A warm microSD card during heavy use is normal, but excessive heat suggests a problem. Remove the card, let it cool, and test with a different card. If the second card also gets hot, the Switch’s card reader may have an issue requiring repair.
Problem 5: “microSD Card Was Removed” Error During Play
This error appears when contact is lost temporarily. Remove the card, clean the contacts, and reinsert firmly. If the problem persists, the card slot may be damaged or the card may be faulty.
Summary
Most microSD card issues are caused by improper handling (hot-swapping) or counterfeit products. Buy from reputable brands, handle with care, and back up your data regularly to minimize the impact of any problems.
