¿Hay alguna manera de limpiar discos posiblemente no válidos que solo se muestran en la Recuperación de Mac OS a través de la "lista de discos" en la Terminal? ¿La recuperación los usa?

6

Espero que la pregunta sea lo suficientemente clara, y espero que esto sea solo una tontería. Cuando inicio en la partición de recuperación, entro en la Terminal y ejecuto 'diskutil list', obtengo unos cuantos discos pequeños y aparentemente no válidos (que comienzan en / dev / disk2):

Ejecuté 'información del disco' en cada uno de los discos y recibí el siguiente resultado:

Algunas de las unidades se montan en lugares conocidos (como / Volúmenes) y algunas de ellas se montan en lugares menos conocidos (como / private / var). Sin embargo, no recuerdo que ninguna de estas unidades aparezca montada la primera vez que tengo mi Mac. ¿Alguien sabe tal vez por qué aparecen estos discos y / o si puedo eliminarlos? Gracias!
