I prefer peaceful and quiet life during vacation,but sometimes I watch football match if my favorite club performs brilliantly in that season. And I love reading, painting and calligraphy, thus I send my friends festival handwriting cards every year.
The Steam Deck, a handheld gaming device developed by Valve Corporation, has garnered immense attention in the gaming community. With its powerful hardware and the ability to run PC games seamlessly, the Steam Deck has become a favorite choice for gamers worldwide.
However, when some users wish to use a larger SD card after formatting on Steam Deck, they receive the notice like “Format Error - The micro SD card failed validation tests and cannot be formatted. Contact your micro SD card manufacturer for support.” The SD card can well work on other device, then how does this occur?
In fact, the error is caused by file system.
The Steam Deck operates on the LINUX platform and utilizes the ext4 partition standard, which is specifically designed for compatibility with UNIX file and folder permissions. This file system is not supported by Windows or Nintendo systems.

In such cases, sending it in for repair is the only option. However, if you are certain that your SD card has not suffered physical damage, you can attempt the troubleshooting method outlined below to resolve the issue.

Step 1. Format the SD card initially using the Switch.
Step 2. Stick the card in the steam deck
Step 3. Then, you must restart the deck completely.
