I am trying to write the image to an SD card on a Win10 machine. I have downloaded the current zip file, unpacked it and tried writing it with Etcher; Result:

I have tried different SD cards and two different SD drives. I have also tried using win32diskimager. All with the same result.

Hi Bernard
Basil's advice isn't totally correct, for some Draw Hats you need to
include in /boot/config.txt the line:
dtoverlay=
as well as the other lines. So the extra lines are (as per UDRC & UDRC II
hats )

dtoverlay=
dtoverlay=draws,alsaname=udrc
force_turbo=1

That is what I had to do with my Draws Hat
