![]() ![]() The result is that the video files are fragmented from the second they are recorded and contain chunks of alien, or foreign data, that doesn’t belong in the stream. However rather than writing the stream to a different part of the card such as at the end, GoPro cameras actually interrupts writing the video and adds in chunks of the metadata as it goes. When a GoPro camera is recording to the SD card it creates not only the video stream but it also creates a metadata file to go with the video stream. With GoPro MP4 files however this isn’t the case. It then assumes that the data in-between is all part of that same file. Most data recovery software assumes files to be continuous and therefore only looks for an opening/closing signature of the file type. Only if a volume to too full might a file become “fragmented” and end up written in two or more places then stitched together by the operating system when it’s accessed. ![]() When a file is typically stored on a computer hard drive or other digital storage media the file is generally stored in one continuous stream of sectors from beginning to end.
