Today I had several flights and hooked up my P3P to my PC to get the .dat files...Ummmm...None to be fond exept the ones on the 16th?  On the 17th I did a firmware update to current.  Where are my .dat files.  Like I mentioned, the ones from the 16th ar in there but nothing else.  I have had several flights since then.

On another note, Litchi is updating however it does online.  I just wat the .dat files jsut in case DJI needs them for somethign someday  ;)

SOmething odd as well, the way I get them is via MACBOOK so I have to go thru some conviluted way to get them but found a link online that shows how to do it.  Short is it used to be under a disk2s1 directory..now it's not there  its disk1s1.  Very ODD!

Can someone help please
EDIT:  Yes, I connected the USB cable to the correct port on the front of the P3P..not the gimbal

Joe

FYI

Here is the link how to do it on a MAC..used to work until after I did the update..Now..Nope

You should still see them all of your computer, do you have view hidden files enabled.
Can you try on a PC as well.
It is strange that it starting doing it just after you updated. There is the slight possibility that something got corrupted in your flight data recorder.

Hidden files are enabled.  I can see the files from before the update.  So, corrupt..how do I resolve that one?

Also, if my bird crashes and I cant recover it..How do I send DJI flight records?  I have all the flight .txt files .  Even todays flights show up..Thats what is odd!  Great flights today and it made me think what if!

I think it;s odd the disk2s1 changed

I find it odd too. an you reapply the firmware and see if it cures it. if not, then downgrade to 1.8 ad see if it generates a .DAT file after restarting the aircraft. if so, then update to 1.9 again and see what happens.

Nice, glad you have them now.
Here's some notes I found that may help with your Mac.
And to reinstall the same firmware that's already on the aircraft, just format the SD card and and run the firmware update. If something didn't take for some reason then it should now.

This method will be more clear and detailed. But it is much more convenient to use Windows:
Here are the steps to access the .DAT files stored on the hidden SD card permanently mounted inside the Inspire 1.

1. Power up everything with the Inspire 1 as if you were going to fly (except the props), and launch the DJI GO App.
Enter the camera view.

2. In the MC Settings menu, choose Advanced Settings. You can find the MC Settings on the top left corner of the screen,
directly to the right of the Home icon.

3. Scroll down, and select Enter flight data mode.

4. The DJI GO app will prompt you to connect the drone to a PC or Mac via the USB to mini-USB cable included with your drone package.
Plug the regular USB plug directly into your Mac (not a USB extension port box).
Note: This was done using a 2013 iMac running OSX 10.8.5, there may be some differences with different models and OSX versions.

5. Once you connect the drone to your computer wait to see if by chance it does mount to your desktop.
When it doesn't, open the application Disk Utility.

6. Select the disk DJI DATA LOG. It will show listed in the left column of disks in Disk Utility.
You can select it even though it is not mounted to the desktop.
(Be sure to choose the root disk DJI DATA LOG file and not the DJI FLY LOG file).

7. When the disk DJI DATA LOG is highlighted, select the New Image icon in the top row.
This will present the dialog box shown, asking what to name it, where to save it and what format.
(I've chosen compressed with no encryption).

8. Be prepared to wait a long time. The amount of time depends on how many .DAT files there are.
The entire SD card could be full. The Inspire 1 records a .DAT file every time it is powered on,
regardless of flight or not. It only erases them when space is needed for newer files.
(I wouldn't start with the Inspire 1 battery less than 50% charged).

9. Once the Disk Image is created on your Mac, double-click it, it will un-compress to a new window
(in temporary RAM memory only). Drag the files you want from there to a newly created folder on your computer.

I'll give that a go on the Macbook..Thanks

Question still remains, if I crash and can't recover the drone, how do I get the flight info to DJI if needed.  Just trying to be proactive.

Thanks a million

If the aircraft is lost then we just use the flight data from the the app.
When you play back the flight in you flight records tab that's pretty much what we use BUT there's additional flight data that DJI has access to.
So if there was a malfunction it DJI will see it. The only time we cannot get any more data is when the video and RC transmission is gone, then it stops sending data.

Most outstanding.

BTW, the mac way you listed here is working and downloading the .dat files.  OUTSTANDING.

Do people do this often to keep the files?  Has to be a faster way for sure.  I use healthy drones but seems like the logs are a bit limited.  I want to keep track of it all.
And

Thank you DJI for the help today!!  AWESOME WORK

There's really no reason to keep the files, it's only needed if there is a problem. And if there is they woudl look at the last few records.
When you connect the aircraft to the computer it uploads any that are new, so if you did it weekly then it would be a fast process.
