Abstract

La présente invention concerne un procédé d’optimisation d’écriture sur un disque dur, caractérisé en ce que le procédé comprend un balayage du disque selon les étapes suivantes : - définition du nombre de blocs par disque, - définition d’un premier bloc, d’un bloc central et d’un dernier bloc du disque, - écriture de données sur le premier bloc du disque, - écriture de données sur un deuxième bloc du disque, le deuxième bloc correspondant au bloc supérieur au bloc central du disque, - écriture de données sur un troisième bloc, le troisième bloc correspondant au bloc inférieur au deuxième bloc, - écriture de données sur un quatrième bloc du disque, le quatrième bloc correspondant au dernier bloc du disque, réitération du cycle d’écriture de données jusqu’à l’épuisement des données à écrire sur le disque. Figure pour l’abrégé : Fig. 2
