Quindi, ho un Apple USB Thumb Drive modello USB A1384 , e mi piacerebbe cancellarlo (in particolare, per creare un simpatico stick per l'installazione USB di macOS Sierra con marchio Apple); sfortunatamente, non sta andando bene adesso:

Qualcuno sa come posso riparare / ripristinare questa unità? Mi piacerebbe davvero usare questo disco specifico , per ovvi motivi; quindi "comprare un nuovo disco, sono economici" non è davvero una soluzione.
