Si busca en el administrador de discos, verá el disco montado con el tipo de sistema de archivos RAW.
El proceso 'nsriscsi' se ejecuta y no se detiene hasta que se utiliza Finalizar tarea en el Administrador de tareas. 

Este error proviene del nivel del sistema operativo.

Solución alternativa:

1. Ver el disco en el administrador de discos. 

2. Haga clic con el botón secundario y elija Propiedades. 

3. En la pestaña Herramientas, haga clic en "Comprobar" para analizar la unidad en busca de errores. Esto puede hacer que la unidad esté operativa para acceder manualmente desde el Explorador de archivos.

4. Si la unidad entra en funcionamiento, acceda a ella a través del Explorador de archivos para copiar los archivos necesarios. Es posible que se requiera Robocopy o una utilidad similar para mantener las ACL o las propiedades de propiedad de archivos.
