One of the recent updates (1.5 maybe) removed the ability to delete the files from the internal disk.  I imagine this was a deliberate decision by DJI to prevent people from wiping out the files if they felt they would be incriminating to a warranty repair. ("No, of course I did not crash it into the ocean, why would you ever think that?")

You may install your personal aluminum foil protective devices if you wish to speculate even more nefarious thoughts by DJI.

The only way to get around this would be to get root permissions to the drive which IIRC, has yet to happen.  

Perhaps one of the DJI twins can expound on this.

There is no way to delete the DAT files from the aircraft. The memory is several gigabytes so it would take some time just burning through batteries flying in an area that you don't care if anyone knows about.

Actually that statement was my own opinion as to why someone wouldn't want logs of their flights, I should delete it.

Inferring malice for being able to delete files is ridiculous. I have considered selling my Phantom pro and would prefer to be able to clear the bird entirely. There's no reason I should be forced to give away information such as where and when I flew to a new purchaser simply because I owned the bird previously.

You can say that it doesn't matter to you, but the ability for a user to wipe a smartphone of pictures is not second guessed - regardless of the nature of the content. I should be able to have some way to clear my history from a device when I am choosing to resell it, even if that process involves some unusual step that I wouldn't otherwise take.

For most users that kind of information isn't going to be giving away anything important.
But for DJI assessing warranty issues, they need to know they are looking at data from the latest flights and that the latest flight data has not been deleted or tampered with.
And since that's the whole reason for having a "black box data recorder" in the Phantom, you're just going to have to accept it the way it is.

If you fly your phantom from your home, and then resell it, any new purchaser now has your address. Unhappy with the transaction? Problem with the Phantom? Consider you a good mark for theft? Sure all these scenarios are unlikely.

If you have ever flown your Phantom at your house or any other personal location, you now have the choice of either: 1. Letting any prospective buyer know about those locations and flights, or 2. Not reselling it.

Do I understand DJI's perspective? Sure it doesn't matter to them. But as a customer, the inability to clear your bird for resale is a serious issue. It doesn't matter if it was a one time code that you had to generate from DJI, put into the GO app, and then would clear the bird until re-authorized by DJI. I should not be forced to either bear a risk that nobody will do anything untoward with that information or to not resell my Phantom if that's a concern.

You have full control over this issue. If you don't want to give away the data, don't sell the aircraft.

Can't you just open up the bird and remove the card and just put another in it?
Kinda like the game OPERATION?  "Remove wrenched ankle"   
Anyone remember that game?

Opening the P3 and getting to the data recorder SD card is no trivial matter.
Add to that, it's glued in.

It think it's pretty much the same stuff.  There was a thread on Phantom Pilots about pulling the card.  A lot of work for minimal benefit.  Yep, somebody knows where you live.  Scary that.   If you have flight logs that implicate you in some nefarious scheme, you should probably shred the device when you no longer need it.

Or just fly it around over water until it crashes.

Are you sure you can't delete them?
This must have been a firmware change since 1.3.2
I have deleted all the DAT files on my P3A a number of times.
I've never updated because it does everthing I want it to do and flies great.

Never mind.....just saw post #2

All of this is definitely going to lead to a FW hack.   (If it hasn't already)  Count on it.
