The micro SD card size is incorrect.
The micro SD card size is incorrect.
I purchased a 256 GB Samsung Evo Micro SD card for my Nintendo Switch and it has functioned adequately over time. After reinstalling Windows on my laptop and wiping the card again, it now shows 20 GB when connected to the Switch. I attempted to reformat it using Windows 11, trying EXFAT, FAT32, NTFS, but none resolved the issue.
Find the partition manager. It probably generated a 20 GB drive, which is what remains after formatting. You’d need to remove the existing partition and set up a fresh one.

SD cards offer poor performance for long-term use. Many photographers use two SD cards in their gear but discard one as soon as it fills up.
