PASF partición inaccesible

Bueno, nadie respondió, pero yo era capaz de recuperar mi APF volumen. Es importante mencionar que se debe tener conocimiento de la distribución de la partición para el éxito de la restauración. Híbrido MBR se extiende por todo el volumen, y cuando me quité las mal colocado volumen de los Híbridos MBR se reduce hasta el punto de no dejar espacio adicional y tengo el error:

gpt add: /dev/disk3: error: no space available on device

Yo era capaz de solucionarlo mediante:

sudo gdisk /dev/disk6
Password:
GPT fdisk (gdisk) version 1.0.5

Partition table scan:
  MBR: hybrid
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with hybrid MBR; using GPT.

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!

Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/disk6.
Warning: The kernel may continue to use old or deleted partitions.
You should reboot or remove the drive.
The operation has completed successfully.

Que convierte de Híbrido a MBR de Protección regular (GPT). Pero todavía APF no tiene el código correcto:

sudo gdisk /dev/disk6
GPT fdisk (gdisk) version 1.0.5

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.

Así que, yo era capaz de emitir:

sudo gpt add -i 2 -b 409640 -s 707245575 -t apfs /dev/disk6
/dev/disk6s2 added

sudo gdisk /dev/disk6

Ahora la APF restaurado el código correcto AF0A y reapareció en la utilidad de disco y pude examinar mis archivos de nuevo.
