Non ho cancellato i file, il mio Hard Disk USB esterno non è rotto, non ha sofferto.
Nella seconda immagine puoi controllare la dimensione dell'1TB HD con la 2a partizione Dimensione di 999.9GB
, ma sul primo puoi vedere 649.69GB
.
Quando seleziono con Finder
l'HD, diventa molto lento. La Finder
non può spostarsi in un'altra posizione appare la ruota colorata. E ho bisogno di spegnere il mio MacBook Air e ricominciare.

La numerazione è diversa per i dischi rigidi?
Mi piacerebbe vedere se fsck corregge il drive ma ha un errore:

Quali argomenti necessitano l'opzione?
