beaglebone-black-make-microSD-flasher-from-eMMC.sh does not write anything to microSD

When I attempt to create a backup of eMMC to a microSD card, I am left with a blank microSD.

@GeorgeSellner who says it's 'blank'? Windows?

Ubuntu

Won't mount. Shows up as only free space in disk utility. No partitions appear. Marked as 'unknown'
Normally, it would just mount it as 'rootfs'

New SD card. Have gone back and written a base image to it, will try again and see if something different happens.
