smartmontools, si tu disco soporta smart, y los modernos lo suelen
soportar, es terrorificamente bueno. 

The pongo un ejemplo con mi disco duro. El cual esta demasiado caliente,
pero no tiene fallos de Current_Pending_Sector, que son los peligrosos.
Y en el resto de cosas es normal. 

Me imagino que si no usas linux, podras bajar alguna distro live como
knoppix que venga con las smartmontools, pero antes de bajarte una ISO
para esto, asegurate en tenga la herramienta esta. Tambien asegurate de
saber como entrar como modo root en esa distro porque lo requiere la
herramienta.
