We own 2 M210's and 2 Z30 cameras.  One is used as a back up ship.

When formatting the SD card on the Z30 I started getting a message that the camera was busy.  We tried firmware updates and all sorts of different fixes and nothing worked.

We used all combinations of the 2 ships and cameras and nothing worked.  Then we discovered the problem has to do with 64GBb cards.  When using a 16GB card everything works with both cameras and drones.

So the bottomline appears that eveerything works fine with 16GB cards but not 64GB when formatting.
