On Sunday, I flew my Mavic Air, taking a video (4k) for the first half of the flight, followed by a couple of panoramas. All seemed normal - as the recording was running, I could see the elapsed time counting on the Go4 display, so I assumed it was recording.
I had some videos on that SD card that were shot earlier in June, in addition to the 06/21/2020 videos. I did my usual copy of the entire SD card to a folder on my PC for storage, and all seemed OK.
Yesterday, I got around to looking at the videos, all were there EXCEPT for the ones from 06/21/2020! I thought maybe somehow they got recorded to the internal storage on the MA, but that was not the case.
I scanned the SD card and internal storage with Rescuva undelete program, and there WERE deleted files on the SD card with sizes that I was expecting, and the prognosis for recovery were Excellent. I restored them all to a folder on my PC (nothing was written to the SD card since the flight on 06/21/2020).
Unfortunately, none of those files were playable, except for a small jpg thumbnail.
Has anyone encountered a situation like this? I looked at the flight record file with CSView, the camera data groups, and confirmed that recording was going on for the first half of the flight, followed by the panorama series. It would seem that the video file was correctly closed, since the recording was terminated normally, as opposed to letting the recording stop on its own when the drone shuts down.
It looks like my only hope for these videos is to work with Rescuva tech support to see what they suggest. Does anybody know of a better undelete program for Win10?
