I saw no issues reading the cards at my PC. For sake of comparison, I just flew 2 more brief flights, one with a Samsung EVO Select Micro SDXC U1 64GB and the other a Sandisk Ultra Micro SDXC 64GB card. But, as I've since proceeded on with using another 128GB card of the same type, that issue again appeared. I thought I had stumbled upon a card possibly going bad on me when in comparison to 5 other MicroSDXC cards of various capacities and either exFAT or FAT32 format, only this one card was failing to work after use in the MA2. I have recently been seeing the same problem of my Windows 10 PC prompting that the Sandisk Extreme MicroSDXC U2 A3 128GB card used in my Mavic Air 2 must be formatted before I can continue. Run CHKDSK with the /F (fix) option to correct these.ĩ53583 allocation units available on disk. Windows has checked the file system and found problems.

Now I will format it before each future flight, but I am afraid it could not be enough.Īny idea about a possible reason for this terrifying experience? The SD is a brand new SandDisk Extreme 128Gb, v30 A2 Class 3. The tool was able to recover all of them in a snap.īut I am definitely concerned now. Thankfully I've been able to recover all pictures & videos using a recovery software (Recuva): all files were there, in perfect shape. but the SD is not readable at all from my Windows PC. The funny thing is that if I plug the SD in my Mavic Air 2, I can see pictures & videos, I can play them, I can download them on the connected iPhone. I then tried CHKDSK /F (in Admin mode, of course), but it could not fix it: 'An error occurred while examining the boot region.' I ran CHKDSK, and it said 'Corruption was found while examining the boot region.'. and I've got this error message: 'Warning: you need to format the disk in drive J: before you can use it'. Today, after my fifth flight, I removed my SD Card from my Mavic Air 2 (as I normally do), I plugged it into my Windows PC.
