The Steam Deck doesn’t ship with a lot of onboard storage, especially if you purchased the base 64GB model. This makes a Micro SD card an excellent option, allowing you to considerably boost the storage space so you can install additional games.
But if you’ve used the SD card on a previous device, such as a Windows PC or Nintendo Switch, then it most likely won’t work until you format the card.
Fortunately, it’s very easy to format an SD card on the Steam Deck, and we’ve created this guide to help you through the process. So keep on reading to find out how you can format an SD card on Steam Deck.
What you’ll need:

Insert Micro SD card into the Steam Deck
You’ll find the Micro SD card slot on the bottom-right of the Steam Deck. Gently press the card in until you hear a little click. It shouldn’t be hanging out of the device.
From homescreen, press the Settings button
On the Steam Deck homescreen, you should be able to see a cog icon on the top row, which we’ve circled in red above. Click on this to enter the Settings menu.
Click on System
You should be hovering over System by default, so click on this to enter the System Menu.
Scroll down until you find the System Settings header. A couple of rows down, you should be able to see the Format SD Card option.
Select Format, and then Confirm
Now select Format. You’ll then get a pop-up window asking you to confirm. Press Confirm, and then your Steam Deck will begin the process. It may take a couple of minutes, but once complete, you’ll be able to start using the extra storage.
If the option to Format SD Card is greyed out, there could be several reasons as to why. Make sure that the SD Card is fully inserted in the correct way, and that your Steam Deck has enough power. Then try restarting the Steam Deck. If it’s still not working, it’s possible that the SD card is faulty or damaged.
We recommend turning the Steam Deck off before removing an SD card. That said, it is safe to remove while the Steam Deck is running, just as long as you don’t have any games running.
