Formater une carte SD/Linux

Ceci est une section complémentaire sur comment formater une carte SD en FAT32.

Cette page est seulement pour les utilisateurs de Linux. Si vous n'utilisez pas Linux, jetez un œil aux pages Windows ou Mac.

Instructions

Avant de commencer ces étapes, copiez tout le contenu de votre carte SD vers un dossier sur votre ordinateur.

Les commandes dans ce guide sont sensibles à la casse. Entrez-les exactement telles qu'écrites, ou il pourrait y avoir des conséquences inattendues.

1. Assurez-vous que votre carte SD n'est pas insérée
2. Ouvrez une fenêtre du terminal et tapez watch lsblk
3. Insérez la carte SD et guettez l'apparition d'un nouvel appareil dans lsblk
4. Lisez le résultat pour le nouvel appareil. Il devrait ressembler à quelque chose comme ça :

   NAME        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
   mmcblk0     179:0    0 29.7G  0 disk 
   └─mmcblk0p1 179:1    0 29.5G  0 part /run/media/user/FFFF-FFFF
   

5. Notez le nom de l'appareil qui apparaît désormais. Dans l'exemple ci-dessus, c'était mmcblk0, mais il pourrait se montrer comme sda ou sdb, si vous utilisez un adaptateur USB.
   • Si `RO` est défini à 1, assurez-vous que le cran de verouillage n'est pas glissé vers le bas
6. Hit CTRL + C to exit the menu
7. Type sudo umount /dev/<device name>* (do not replace the *)
8. Install the fdisk and dosfstools packages using your package manager of choice
9. Type sudo fdisk /dev/<device name>
10. Enter o, this will create a new MBR partition scheme
11. Enter n, then press enter until you're returned to the prompt
    • The default values will work fine for all consoles
12. Enter t, then enter 0c
13. Enter a and then p - observe the output, and make sure the device is now formatted correctly:

    Disk /dev/mmcblk0: 29.72 GiB, 31914983424 bytes, 62333952 sectors
    Units: sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disklabel type: dos
    Disk identifier: 0x########
    
    Device                Boot  Start      End  Sectors  Size Id Type
    /dev/<partition name>        8192 62333951 62325760 29.7G  c W95 FAT32 (LBA)
    

14. If there are no issues, enter w - this will save changes and exit the fdisk prompt
15. Type sudo mkfs.vfat /dev/<partition name> -s 64 to reformat the new partition
    • If the SD card is over 32GB in size, change 64 to 128
16. Type sudo eject /dev/<device name>, then remove and reinsert the SD card
17. If the SD card had any files and folders on it before the format, copy everything back from your computer, unless you were linked to this by another guide that needs the SD to be formatted and blank

1. Make sure your SD card is not inserted
2. Open a terminal window and type watch lsblk
3. Insert the SD card and watch for a new device appearing in lsblk
4. Observe the output for the new device. It should match something like this:

   NAME        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
   mmcblk0     179:0    0 29.7G  0 disk 
   └─mmcblk0p1 179:1    0 29.5G  0 part /run/media/user/FFFF-FFFF
   

5. Take note of the name of the device that now appears. In our example above, it was mmcblk0, but it could show up as sda or sdb, if you use a USB adapter<
   • If RO is set to 1, make sure the lock switch is not slid down
6. Hit CTRL + C to exit the menu
7. Install the parted and dosfstools packages using your package manager of choice
8. Type sudo parted /dev/<device name> mklabel msdos
9. Type sudo parted -a opt /dev/<device name> mkpart primary fat32 0% 100%
10. Type sudo mkfs.vfat /dev/<partition name> -s 64 to reformat the new partition
    • If the SD card is over 32GB in size, change 64 to 128
11. Type sudo eject /dev/<device name>, then remove and reinsert the SD card
12. If the SD card had any files and folders on it before the format, copy everything back from your computer, unless you were linked to this by another guide that needs the SD to be formatted and blank
