Abstract

L'invention concerne un procédé et un dispositif de traitement de données, destinés à être utilisés pour résoudre le problème de corruption de données dans l'état de la technique, dû à la non-exécution d'une opération correcte lors du retrait d'une carte SD. Le procédé comprend les étapes consistant : au cours d'un processus d'écriture de premières données sur un dispositif terminal dans un dispositif de mémorisation de données amovible couplé au dispositif terminal, lorsqu'il est détecté que le dispositif de mémorisation de données amovible est retiré du dispositif terminal, à mémoriser des secondes données des premières données non encore écrites dans le dispositif de mémorisation de données amovible dans un support d'informations prédéfini du dispositif terminal ; et, quand il est détecté que le dispositif de mémorisation de données amovible est couplé à nouveau au dispositif terminal, à écrire les secondes données du support d'informations dans le dispositif de mémorisation de données amovible.
