### 중요

이곳은 3DS와 쓰기 위한 SD 카드를 포맷하는 부가 섹션입니다.

만약 3DS가 이미 SD 카드를 인식한다면, 이 가이드는 따를 필요가 없습니다.

이 페이지는 Linux 사용자를 위한 페이지입니다. 만약 Linux에서 하는 것이 아니라면, [SD 포맷하기 (Windows)](formatting-sd-(windows))나 [SD 포맷하기 (Mac)](formatting-sd-(mac)) 페이지들을 찾아봐 주세요.

### 진행 방법

1. Make sure your SD card is **not** inserted
1. Launch the Linux Terminal
1. Type `watch "lsblk"`
1. Insert your SD card into your PC
1. 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
```
1. 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
1. Hit CTRL + C to exit the menu
1. 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
