The recommended micro SD cards for DJI drones are not cheap and if you have lots of batteries and or more than one drone you need a big one.
I pulled a 64 Gb one from a
M2 Zoom the other day and found it was corrupt. Neither a Mac, Windows or Android OS could even see the SD card.
I was about to shed out $70 Au for a good one when I searched and came across this freebie.
Downloaded it, ran it, stuck my card in the Mac and the software saw it immediately and let me format the old card and saved me shekels.
Thought I would post to share and incase there are others with a similar issue with the new Mavics
