Problems recording videos in Hubsan h501 drone.

I’ve been playing with my new drone, Hubsan h501c, and experienced problems capturing videos. I installed the micro SD card in the drone, flew it and “recorded” videos. Once I plugged the card into a computer, it was empty. I read a few suggestions online, but seems they were (somewhat) incomplete. After many trials and errors, here’s my suggested sequence of steps that, so far, worked 100% of the time:

  1. Plug-in the micro SD card in a Windows-based computer and format it with exFAT filesystem. exFAT is a lightweight filesystem, similar to FAT32 but without its limitations (e.g., 4GB max file size).
  2. Perform safe eject/removal.
  3. While the drone is powered off (disconnected battery), plug in the card.
  4. Start the drone and calibrate. Capture videos.
  5. Land the drone, wait 2–3 minutes and only then power it off. (Sometimes the videos take a few seconds (minutes?) to finish writing on the card after you stop recording).
  6. Remove the card and view the videos on the computer.

I format the card each time before I plug it into the drone. Otherwise, it’s not recording. Plugging/removing the card while the drone is powered on also seems to occasionally leave the card empty.

Enjoy.
