Hi there, the other day I went for a flight with my phantom standard, all normal but message on the app said reformat ad card, brought  it in and did the reformatt through my laptop, tried another flight and now it's saying reformatt recomendent , still records though, never happened before, what to do?

Try formatting the SD card in the aircraft, there is a function in the Go App to do that. For future reference, it is always best to format the card in the camerra rather than on an external computer.

Thanks geebax  will give it a try after work

Hello Rick, you can try to format the card in DJI GO app.Besides, you can also format it into FAT32 with 32KB unit in your computer.
