Not the first time I’ve encountered the bad logging issue but encountered it again this week. Sometimes the bad logging appears in flight and sometimes it prevents the aircraft from arming all together. The last time I had this issue swapping the SD card was a quick and easy fix. This time around I discovered there can be a little more involved in getting the aircraft back up and running.
All SD cards I have used are formatted as FAT32
First SD card that failed was an 8gb San Disk Edge, I replaced it with another 8gb San Disk that was used in a 3D printer without doing any special formatting an it has yet to fail in my quadcopter.
The second failed SD card was also a 8gb San Disk Edge, initial swapping to another SD card did not fix the issue on my Hexacopter(3.6.9).
What did work was buying new SD card, a San Disk Ultra Plus 16gb card, and formatting it to FAT 32 with some free software.
The formatter I used was from https://fat32-format.en.softonic.com/
It seems to work well and the new SD card has yet to give any errors on the ground or during flight.
I plan on also testing another PNY Elite 16gb card to see if I can find any patterns as to why my cards keep failing and what the best options are.
Ill update this post with whatever I find.
