After few months in storage I powered up my never-crashed P3P with its well-behaved stock Lexar Class 10 U1 16 GB SD card that I always reformat in the AC.
In the Main Controller MC settings or in the main screen there was a new alert "Reformat Recommended" or "Advice Format". But MC reformat failed with an error "SD Card Format Timeout" and the camera settings reformat failed with an error "SD Card Formatting Failed".
In my repeated attempts I managed to successfully reformat the card just 2-3 times and eventually it always failed.
I could however take video and images to the card via the RC buttons while trying to take footage via the tablet's GUI did not do anything (DJI GO v3.1.23, iPad Pro 9.7", iOS 11.2.1). I even managed to update the P3P FW from P3X_FW_V01.10.0090 to P3X_FW_V01.11.0020 from the SD card which could be reformatted in the computer just fine (MS-DOS (FAT), Master Boot Record -- I also tried ExFAT but it made no difference).
I assumed that the SD card had gone bad and got a new Transcend Class 10 U1 16 GB SD card. But reformatting it in the AC failed in the same manner. Also an old 3rd (too slow) SD card failed to reformat in the AC (main screen warned that it is too slow).
Then in desperation I fired up my old iPad mini 1, downloaded DJI GO and, surprisingly, the Transcend card reformatted successfully many times.
Then I deleted the DJI GO from the iPad Pro 9.7", re-booted, re-downloaded DJI GO app, logged in to DJI and could reformat the card a few times until it failed and then succeeded again. Now I'm afraid to take the card out or try to reformat it.
What is going on? It seems the three SD cards are OK. Is the P3P disk drive going bad? Or is this a software issue?? What should I do if the disk drive is bad?
