I found this procedure on the webs and used it slightly modified, as outlined below.

Become root with sudo su -
Insert the USB drive, and find its device name.


sdk                 8:160  1  31.6G  0 disk
└─sdk1              8:161  1  13.7G  0 part /run/media/gill/OCTD

Unmount the partition.

umount /dev/sdk1

Run fdisk with the device name and remove existing partitions.
