### Lectură obligatorie

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.

Această pagină este doar pentru utilizatorii de Linux. If you are not on Linux, check out the [Formatting SD (Windows)](formatting-sd-(windows)) or [Formatting SD (Mac)](formatting-sd-(mac)) pages.

### Instrucțiuni

1. Make sure your SD card is **not** inserted
1. Launch the Linux Terminal
1. Type `watch "lsblk"`
1. Introduceți cardul SD în calculator
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
