Revision 1.0: Just to help people out ASAP – will be revised with videos and further informaton – however this guide will help you now.
You can first try simply fomatting the card in a computer, then trying it again. If this fails like it did for me, I was able to solve the issue by using a different MicroSD card, which it also wouldn’t format or read properly, and then connecting the DJI Pocket 2 to the computer via USB.
Eventually on-screen it will asks if you want to Connect to Computer. Say yes, and a new drive will appear in My Computer.
Interestingly, it reported the size as 128gb, even though the card was 64gb. The previous and main card however, was 128gb. A Sandisk Extreme MicroSD 128gb to be exact – one which seems to be a common theme amongst DJI users.
What I did then was proceed to format the card, using the Computer Management tool in Windows. DO NOT FORMAT from My Computer in the usual way of right-clicking and pressing format.
Open the Computer Management screen by bringing up the start menu and simply start typing “Compute rManagement” untl you see the option appear, and hit enter.
You will see the following:
The above will look slightly diffeerent for your system; look for the USB MicroSD – it will probably have the highest letter of the alphabet as it is the most recent device to be added to the list of disks. So fo rexample it might be drive D: or drive E:.
Right click on the bar which represents the drive, and select DELETE VOLUME. You may notice there is more than one section, for example some “Unallocated Space”, while the majority of it says e.g. 63 GB exFat (or 63 GB NTFS). None of these details matter – the crucial thing is to make sure you are definitely looking at the MicroSD card – you don’t want to accidentally delete one of your Hard Drives, SSDs or other defvices.
Delete any and all sections until the Blue bar is now Black, and it says Unallocated Space – it won’t have a drive letter (e.g. “D”).
Now right click anywhere inside this bar and select Format – choose exFAT and you can Quick Format; after around 10 seconds or less, you will now have a MicroSD drive again in My Computer. It will have whichever letter you assigned to it duing the format stage.
Disconnect the DJI Pocket from the Computer by removing the USB C cable from the DJI.
Turn the DJI Pocket 2 off by pressing and holding the Power Button, and then turn it back on.
Your device should now be working! Try taking a photograph and if the red light flashes and you see it writing to the MicroSD card – congratulations, your DJI Pocket 2 is back to normal again!
You can now insert your original MicroSD card – and it should work normally; if you have any issues, try Factory Resetting the DJI Pocket 2.
It may be possible to fix this issue without a second MicroSD card – I believe it is but I haven’t tested it as it hasn’t broken on me again since.
I believe this issue has something to do with the DJI Pocket’s management of File Tables (as evidenced by it thinking my 64gb MicroSD was 128gb – it was treating the second MicroSD as if it was the first one).
There is more to this issue, and more detail to be uncovered – I may explore it further and provide more specific, definitive detail – IF the issue arises again. I believe it will, as it happened in the first place without any known cause. Suddenly the recording wasn’t reliable, the menus behaved slightly oddly.
