Formatting an SD card/Linux: Difference between revisions

Revision as of 02:43, 23 June 2022

This is an add-on section for formatting an SD card to work with the 3DS.

If the 3DS already recognizes the SD card, this guide is not required.

This page is for Linux users only. If you are not on Linux, check out the Windows or Mac pages.

Instructions

Make sure your SD card is not inserted
Launch the Linux Terminal
Type watch "lsblk"
Insert your SD card into your PC

Observe the output. It should match something like this:

NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
mmcblk0     179:0    0   3,8G  0 disk
└─mmcblk0p1 179:1    0   3,7G  0 part /run/media/user/FFFF-FFFF

Take note of the device name. In our example above, it was mmcblk0p1
- If RO is set to 1, make sure the lock switch is not slid down
Hit CTRL + C to exit the menu
Type in the following for your SD card:
- 2GB or lower: sudo mkfs.fat /dev/(device name from above) -s 64 -F 16
  - This creates a single FAT16 partition with 32 KB cluster size on the SD card
- 4GB - 128GB: sudo mkfs.fat /dev/(device name from above) -s 64 -F 32
  - This creates a single FAT32 partition with 32 KB cluster size on the SD card
- 128GB or higher: sudo mkfs.fat /dev/(device name from above) -s 128 -F 32
  - This creates a single FAT32 partition with 64 KB cluster size on the SD card
