No eliminé los archivos, mi disco duro externo USB no está roto, no sufrió una caída.
En la segunda imagen, puede verificar el tamaño del HD 1TB con el tamaño de la 2ª partición de 999.9GB , pero en la primera puede ver 649.69GB .
Cuando selecciono con Finder el HD, me vuelvo muy lento. El Finder no puede moverse a otra ubicación, aparece la rueda de color. Y necesito apagar mi MacBook Air y comenzar de nuevo.

¿Es diferente la numeración de los discos duros?
Me gustaría ver si fsck corrige la unidad pero aparece un error:
$ sudo fsck -f -l /dev/disk2s2
