Abstract
EN UN SISTEMA DE CACHE DE DASD, EN EL CUAL LAS PAGINAS DE LOS SECTORES DE DATOS SON ALMACENADAS LEYENDO EN UN SECTOR DETERMINADO Y BUSCANDO PREVIAMENTE UNA PLURALIDAD DE SECTORES ADYACENTES PARA ACCESOS POSTERIORES, LOS ERRORES EN EL MEDIO DE ALMACENAMIENTO DE DISCO PROVOCAN SEÑALES DE ERROR QUE SERAN GENERADAS. TALES ERRORES SON MANEJADOS ALMACENANDO INDICACIONES DE CUALES SECTORES TIENEN ERRORES Y CUALES NO, Y ACCEDIENDO A DICHAS INDICACIONES EN RESPUESTA A PETICIONES POSTERIORES DE TALES SECTORES. DICHAS INDICACIONES SE ALMACENAN EN CADA PAGINA EN EL CACHE. ADEMAS, SE MANTIENE UN HISTORICO DE LAS PAGINAS Y SECTORES QUE FUERON COLOCADOS EN EL CACHE EN EL PASADO.
