Typical error:

--> Zapping: /dev/sdu1
Running command: /usr/bin/dd if=/dev/zero of=/dev/sdu1 bs=1M count=10 conv=fsync

-->  RuntimeError: Unable to detect the partition number for device: /dev/sdu1

in this case, `udevadm info --query=property /dev/sdu1` returns this :

we can see "ID_PART_ENTRY_NUMBER=1" is well present.

there might be a race condition.
