Abstract

UN SUBSISTEMA DE RECUPERACION DE ERROR DEL DISCO DURO, QUE ESTA EN UN SISTEMA DEL ORDENADOR (10) DEFECTUOSO CONSTA DE UN SUBSISTEMA DE REVISION QUE SE COMPONE DE UNA REGION DE DIVISION DE REVISION ESPECIFICADA (16) SOBRE UN DISCO DURO (24) DEL SISTEMA DEL ORDENADOR. LA REGION DE DIVISION DE REVISION ESPECIFICADA TIENE UN CAMPO DE ENCABEZAMIENTO DE REVISION (28) Y UN CAMPO DE MEMORIA INTERMEDIA DE REVISION (30). CUANDO EL SISTEMA DEL ORDENADOR ACCEDE A LA FUENTE DE DATOS PARA MODIFICAR UN DATO ALLI, EL DATO ORIGINAL SE TRANSFIERE AL SUBSISTEMA DE REVISION, EL CUAL RETIENE EL DATO ORIGINAL Y UNA HISTORIA DE LA MODIFICACION Y UNA HISTORIA DE OTROS SUCESOS QUE OCURREN EN EL SISTEMA DEL ORDENADOR. EL USUARIO PUEDE RETROCEDER A UN ESTADO PREVIO DESEADO DEL DISCO DURO USANDO LOS DATOS ORIGINALES RETENIDOS. LA HISTORIA RETENIDA DE LAS MODIFICACIONES Y LA HISTORIA RETENIDA DE LOS SUCESOS QUE OCURREN EN EL SISTEMA DEL ORDENADOR.
