SSD via USB angeschlossen angeblich nicht formatiert

OFFTOPIC:

Single partition without MBR — This option is available for USB flash drives only. Normally USB flash disks do not have an MBR and their single partition is placed starting from sector 0.
Nevertheless it is possible to create a flash drive with an MBR.
It might be the preferred option when drive must be made bootable.
