I had succeeded to place the image of Raspbian Jessie on the FAT32 formated HDD with 1 TB, copied the required files to the boot partition on the microSD and have the new Raspbian Jessie start. Now I followed the instructions to have the data partition of the USB-HDD be expanded to include all available space on the 1 TB USB-HD! This failed and resulted in the screen remaining black when the GUI of Raspbian Jessie should appear and a irregular blinking image of a cursor as in a command line...
