Cómo modificar particiones y crear un sistema de archivos en un dispositivo de almacenamiento masivo USB

Idioma:

Los siguientes pasos describen cómo suprimir una partición existente, crear una nueva partición y luego crear un sistema de archivos PCFS en el dispositivo USB. Asegúrese de realizar copias de seguridad de los datos antes de llevar a cabo esta tarea.

Conviértase en un administrador.
Modifique las particiones de la siguiente manera:
1. Inicie la utilidad fdisk.
```
# fdisk device
```
2. En la interfaz interactiva que se muestra, seleccione las opciones adecuadas para las acciones siguientes según se le solicite.
  - Suprima la partición.
  - Especifique el número de partición que desea suprimir.
  - Cree la partición.
  - Seleccione el tipo de partición que desea crear.
  - Especifique el porcentaje de espacio en disco para usar para esta partición.
  - Especifique si la nueva partición estará activa o inactiva.
  - Actualice la configuración del disco y salga.
Desmonte el dispositivo, si es necesario.
Para obtener más información sobre el desmontaje de un dispositivo USB, consulte Cómo montar o desmontar un dispositivo de almacenamiento masivo USB.

Cree el sistema de archivos PCFS en esta partición.

# mkfs -F FS-type -o FS-type-specific-option raw-device-file
