SBLive creation fails during write (2)

Hi,

I have been trying to create a bootable usb using a 8,1 GB Sblive just done by Systemback but I got an error message "Live Write aborted. An error occurred while unpacking the Live System files". I tried few times and got the same result even after previous formatting the destination USB Drive (16 GB).
Here under in the output code for command DBGLEV=3 systemback-sustart
