I have a huge problem.  My videos delete themselves from my card automatically without me deleting them.  As I'm sure you are aware, this is a very serious problem for me.  I recently took a vacation on the Gulf of Mexico.  I recorded several videos, some of them with my children in the ocean.  When I returned that day to view them on my computer, I only had 3 videos, and I had recorded at least 6!  The videos appear on the DJI GO app, but they are no longer on the card.  Today, I had my nephews soccer semi-final game.  I recorded 6 videos again, and only three of them were on the card, it appears it kept the last 3 videos I recorded.  I am using a SanDisk Extreme Plus 64GB XC1 U3.  I'm desperate, Phantom 3 Professional is useless if I keep losing the video!  Is there a way to retrieve the 4K footage from the DJI GO app?  Why is this happening?  Although the files were probably the last 3 I recorded, they were labeled DJI_0001, DJI_0002 and DJI0003.  The operating system created 2 folders in the DCIM folder, 100MEDIA and 101MEDIA.  My videos were stored in 100MEDIA and there is nothing in 101MEDIA.  I can't believe this has just happened.  Anyone out there with the same problem????

have u tried another sd card.
is the sd card formatted to full capacity?
r u sure, if using windows, the os is not automatically copying vids and pix from sd and then deleting them?

There is a setting to make your recordings continuous and not start from 01 each time.

yes but that wouldnt delete his videos, it would just reset the index

Never seen my P3 create the 101MEDIA folder. Thought this was only created when there was 10,000+ items in 100MEDIA..

Could be a bad file system on the card. Try formatting the SD using the Go App or using the 16Gb SD card that came with the P3..

Thanks for your reply.  As a test, I inserted the 16GB card that came with the P3.  I recorded 8 videos after formatting the card and starting clean.  On each video, I had a paper in which I wrote down 1 and recorded, stopped, the recorded again a sheet of paper with the number 2, and kept going until I recorded the number 8.  If it was going to delete a video, I wanted to know which one it deleted, if it did the same as with the Sandisk card and deleted the older videos and replaced it with he newest videos.  When I removed the card (on a Mac system), it kept all 8 videos.  I am going to perform the same test with he Sandisk card.  I hope it's just bad sectors on the card.  I'll keep you guys posted.  I am sorry to say, I lost a few videos I took of my kids on the beach in Destin Fla.  Oh well, good excuse to take them back!
