error: unrecognized disk label

[jerabaul29]

I hit an error when running the script (rpi-clone the SD card of the built in reader into a USB SSD drive). However, things look fine. Any idea what this implies / how to fix? See the Error: /dev/sda: unrecognised disk label below.

pi@raspberrypi:~/Git/rpi-clone $ lsblk
