I was shooting yesterday for about 30 minutes, then my Canon R6 Mark II threw an Error 70 and stopped recording. File gone, but left a .DAT file with the correct name, but it’s 0 bytes. A videographer sent us message for help.
First of all, it is very important, please don’t recording any new video on the same SD card to avoid data overwriting, you should replace a new SD card or use another camera to recording the next footage.
This is a common issue with camera freezes and power outages, but it’s a very complex process to recover the file without any data. The DAT file size is 0,it has nothing, it means the camera isn’t properly saving the data to a file, it is impossible to recover video from the 0 byte file.
Based on the client’s description, since he recorded an additional 3 minutes, 100% recovery is not possible, but 90% recovery can be done. With the client’s cooperation, our professional video file recovery team effectively recovered the remaining 90% of the video content, minimizing the video loss. The client was very satisfied with the results.
