MicroSD card not showing up on Steam Deck after swapping?

I have a 256 GB Steam Deck. To extend storage, I got two Sandisk Extreme Pro microSD cards. I then formatted one of them in gaming mode, installed games on it, and played a bit. After that, I removed the first SD card and replaced it with the second. Then I repeated the things I did with the first card on it and swapped back to the first one afterward. The SD card now works in Dolphin but doesn't show up in Steam. I formatted the cards on my PC and they work totally fine on Windows. Any suggestion?

Try the following tips to show your microSD card in Steam Deck:

  • Reboot your Steam Deck.
  • Format your microSD card again in Steam Deck.
  • Make sure your device isn't undercharged.
  • Try safely eject the microSD card and reinsert it again.

Since the issue rises after you eject the SD card, it may be caused by improper ejection. Improperly removing the SD card may corrupt it and render it not showing up in Steam Deck.

Although "ejecting and swapping microSD cards while in game mode is safe," it shouldn't be done while a game is running. To safely remove a microSD card from Steam Deck, you should shut down the device, remove the SD card, then turn it on and insert the card.
