Después de leer sobre la página man de fsck_hfs, siento la necesidad de reconstruir los catálogos. Sin embargo, cuando hago una reparación antes de la reconstrucción, tuvo éxito, pero luego imprimió un montón de errores durante la construcción, y luego ninguno de nuevo durante una verificación después de la reconstrucción. Aquí está la salida de la reconstrucción de un disco local (Seagate Backup 5T)
