Hi everyone, filming with a EOSM6 and got a "memory card error" during a shot. The camera locked up hard, flipping the power switch wouldn't turn it off so I pulled the battery and it wouldn't come back on once re-inserted. I had to use a second battery to get it to power on, even though the initial batter wasn't dead. Strange behavior for sure.
So what I have on the memory card (that is totally functional according to a test in windows) is a 3~ish GB .dat file. It copies off the SD card to my windows machine flawlessly, but is clearly not usable in any way, even if I manually rename the file to .mp4 VLC and Sony Vegas can't understand what it is. Is there any way to recover this file?
I tried putting it back in the camera (which is acting fine now) to see if it'd try to rebuild the file, but it just blinks the green light for a while and gives me a "can't playback this file" error.
