How Do I Format the SD Card on my Mavic Pro?
There are two ways to format the memory card on your Mavic Pro. Both are easy, but one involves an extra step. I'll show you both and you can decide which you prefer.
The Easiest Way
Connect your phone or tablet to the Remote Controller. Launch the DJI Go4 app, power up the Remote Controller, then power up your Mavic Pro. When everything is connected, tap "Start Flight" on the splash screen.
The Aircraft Status screen shown here should open. If it doesn't, just tap the green bar with the words Ready to Go in the top left corner of the screen. Scroll down to the very bottom. Tap on the word Format then tap OK when it asks you to confirm.
Another (still easy) Way
If you are already adjusting your Camera Settings, you can go ahead and format the card right there without needing to go to the Aircraft Status screen. Here's how.
From the DJI Go4 home screen, tap the Camera Settings icon at the right side of the screen.
Now tap on the little gear icon at the top of the screen.
Scroll down the list of options until you get to the bottom. Tap on Format SD Card, then tap OK when you're asked to confirm.
