Tengo 7 sistemas que ejecutan la configuración a continuación. De vez en cuando un disco diferente se desconecta, pero en una inspección más cercana el disco es bueno y no está defectuoso y funciona sin problemas durante al menos otro año. Dado que esto sucede en los 7 sistemas, me parece poco probable que haya una sola parte que esté actuando (por ejemplo, un cable), pero que en cambio es la combinación de algunas de las partes que son ligeramente incompatibles.
El problema es localizar el punto exacto donde está la incompatibilidad.
(Si, en cambio, tiene una solución alternativa en la que puede volver a colocar el disco duro virtual desde la línea de comandos, entonces puede responder /server/523315/re-activate-device -que-se-considera-muerto ).
