I had a Samsung micro-SD card laying around from a dash cam I no longer use. It is 128 GB, so FAT32 isn't an option. I had the card formatted exFAT, and I can see it on both my Mac laptop and PC desktop. I tried to use it in the Chronos today, and the camera refused to recognize the card at all (wouldn't even show up in the storage device list). Thankfully, I had an extra 8 GB Kingston Class 10 card laying around (that I later found out was formatted FAT16 with a 60 MB partition, causing other problems described in another thread).
Has anybody been able to format a 64 or 128 GB card in a manner when the Chronos will recognize it? If so, how?
