Comprobación de la compatibilidad con medios

En el siguiente script se examinan las características de los medios cargados en el dispositivo de disco. Más concretamente, comprueba el tipo de medio y el estado actual del medio, así como la compatibilidad de grabador y multimedia. Este script se puede adaptar para comprobar los problemas de compatibilidad y estado antes de usar los medios.

' This script examines characteristics of the media loaded in the disc device.
