It happens at every time: when I connect the drone, I get warned by windows that the usb drive needs to be analyzed and corrected.
The same thing happens with my little Spark. I let it go and I do not analyze and no correct anything, and everything has always worked
correctly. I opened this discussion to find out if it will happen to you and how you do.

I get it too.  When I take the card out and connect it to the PC.  Just something to live with.

I don't remove the sd card usually, but connect AC with usb cable to PC and download pctures and movies, at this time get the alert. Sure, i don't want my PC, format, or do some like that, at the SD or other drone's memory card they are inside the AC.  So i don't care about that and make my operations.

Hi, thanks for reaching DJI Forum. We do apologize for the troubles. I'd like to know if you already switch and use a different cable? Also, what is the firmware version of your aircraft? We're here to help you. Thank you.

Tanks for try to help me.
My Sparky's firmware is the old version 01.00.0700 and my M2Z wersion is the last 01.00.00.00.
I for each AC use the stock cable to connect to my Windows PC

Hi, thanks for your fast response. You might need to use another computer for you to update the firmware of your aircraft for your Spark. I would like to confirm what is the Mavic series you own?

in relation to the Spark, I have already tried to change pc, with the same result. However I do not intend to update the firmware: the problems that many complain, can not be compared with a warning that i can not consider. My the Sparky that now flies perfectly with OTG and more.
About the M2Z serial is some like OM6DF7T*******
Thanks for the interest
