I just found one rather odd item. I've been using
https://etcher.balena.io/ for writing image files and it does not seem to care if what the image file extension is. When I wrote the kobo_libra2.raw file, there was no issue. When I used the USB Duplicator Image Writer tool, it wrote the image and then threw a write error message. I then used the
SD Card Association formatter to format the card before writing and the error did not occur.
