Abstract

La présente invention se rapporte au domaine technique du stockage, et concerne un procédé de vérification de système de fichiers, un dispositif électronique et un support de stockage lisible par ordinateur. Le procédé de vérification de système de fichiers comprend les étapes suivantes : vérifier si un processus de vérification de système de fichiers existe dans le dispositif électronique; si le processus de vérification de système de fichiers existe, stocker un état d'exécution du processus de vérification de système de fichiers sur un disque, l'état d'exécution étant utilisé pour déterminer une position de départ lorsque le processus de vérification de système de fichiers effectue un balayage complet sur un système de fichiers après le redémarrage du dispositif électronique. Après le redémarrage du dispositif électronique, lorsque le balayage complet doit être effectué, le processus de vérification de système de fichiers peut commencer à effectuer le balayage complet à partir de la position de départ, de façon à réduire les doubles vérifications dans le processus de vérification de fichiers, ce qui réduit la durée de démarrage.
