Hi everyone, it's my first thread here 
I've got my drone for 3 years and unfortunately i came with a problem i cannot resolve myself i hope someone can help me. I see this errors for the first time.
Problem?
My drone don't read any SD Cards, on controller i get notification "SD CARD ERR CHECK APP", also in DJI app i got notification "Unknown internal storage error"
Was unit in a crash?
No
What have you tried so far?
I tried to format my both SD cards (SanDisk Extreme 16gb, Samsung EVO 64gb) inside DJI app but i got message "SD card formatting failed". Then i tried formatting both cards via PC both in FAT32, exFAT, NTFS format. I also via DJI assistant again installed latest update. I want to mention that both cards worked perfectly so far and i didnt fly very often so they are for sure not dead.
What device are you using ( iphone , ipad, Samsung , etc)? Oneplus Nord N10
What firmware are you running ( aircraft, remote controller)? V01.04.0500,
What Go app version are you using? 4.3.37
Any modification? No
Did you change anything or install any apps? No
Do you have a video or pictures of the problem? (if so post link)
I hope someone will help me thank you!
