What You Need

• La dernière version de SD Memory Card Formatter
• La dernière version de guiformat

Instructions

1. Insérez votre carte SD dans votre ordinateur
2. Si la carte SD contient des fichiers et des dossiers, copiez-les tous vers un dossier sur votre ordinateur
3. Lancez SD Card Formatter Setup (le fichier .exe) présent dans l'archive .zip téléchargée avec les droits Administrateur, puis installez le programme
4. Lancez SD Card Formatter depuis le Menu Démarrer
5. Sélectionnez la lettre de lecteur de votre carte SD dans le champ "Select card"

   Assurez-vous de choisir la bonne lettre de lecteur, sinon vous risquez d'effacer accidentellement le mauvais lecteur !

6. Ensure that "Quick Format" is selected
7. Click "Format"
8. Click "OK"
9. Wait for the format to finish
10. Click "OK"

You're not done yet! Your SD card will be formatted to exFAT at this point. The following steps will format it to FAT32.

11. Close SD Card Formatter
12. Run guiformat.exe
13. Select your SD card’s drive letter for "Drive"

    Make sure you choose the correct drive letter, otherwise you might accidentally erase the wrong drive!

14. Select a size for "Allocation unit size"
    • If the SD card is 64GB, choose 32768
    • If the SD card is larger than 64GB, choose 65536 (note that if GUIFormat reverts to 32768, this does not mean it selected the wrong cluster size!)
15. Ensure that "Quick Format" is selected
16. Click "Start"
17. Click "OK"
18. Wait for the format to finish
19. Click "Close"

To confirm that your SD card was formatted correctly, navigate to This PC, right-click the SD card drive, and select Properties. Ensure that the file system is set to FAT32.

20. 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

Common errors with guiformat

Failed to open device: GetLastError()=32

Close everything that may be using the SD card, such as any File Explorer windows. If it does not resolve the issue, try formatting the card to NTFS, then run GUIFormat again.

GetLastError()=1117

Your SD card write-protection switch may be enabled. The lock must be flipped upwards to allow writing to the SD card (including formatting).
