Tengo un disco duro externo Toshiba MQ01ABD100 de 1TB en una caja externa. Recientemente ha dejado de ser accesible. Cuando se conecta a un Mac, aparece el mensaje "El disco que ha insertado no puede ser leído por este ordenador" con 3 opciones: Iniciar..., Ignorar y Expulsar. Me gustaría recuperar los datos de este disco duro externo ya que he copiado allí algunos archivos de trabajo como copia de seguridad antes de rehacer mi Macbook. Estoy usando el iMac en el trabajo para publicar esto y estaría haciendo el trabajo de recuperación aquí también.
Aquí están los resultados de algunos de los comandos que vi correr en otros temas...

He intentado leer otros posts que aparecieron buscando en Google los mensajes de error y parece que apuntan a la corrupción de la tabla de particiones? Espero que alguien pueda aconsejarme y guiarme en este proceso. Es super frustrante ya que no parece que pueda encontrar nada similar a esto.
Saludos, chris

¿Qué esperabas encontrar? ¿Cuántos volúmenes? ¿Qué tipos de volúmenes? Hay APFS, JHFS+, NTFS, FAT, ExFAT, etc. ¿Sabes si la unidad utilizaba un particionamiento de tipo MBR o GPT?

@ David Anderson - Sólo hay 1 volumen en este hdd ext. Está formateado con la Utilidad de Discos. El tipo de volumen es ExFAT y utilizando el tipo de partición MBR.

Por cierto, "Deberá eliminar esta partición o redimensionarla en otra utilidad"... ¿qué utilidad?

@David Anderson ¿alguna idea?

El valor de 2 en la columna de inicio de la salida de fdisk parece sospechoso. Podrías publicar la salida de
dd if=/dev/disk1 skip=1 count=2 2>/dev/null | hexdump -Cv
. Es posible que tenga que hacer undiskutil unmountdisk /dev/disk1
antes de introducir el comando.0 votos
@David Anderson actualización de resultados arriba. gracias de nuevo por ayudar con esto.

@David Anderson He leído muchos otros hilos pero no he encontrado nada similar a mi situación. Así que gracias de nuevo por la ayuda.
