I used Recuva to recover some .mov video files i deleted by mistake on an SD card from my sjcam action cam. The software recovered the files, but it only showed them as part recovered.
I have tried to open these files with Adobe Premiere Elements 15 and with Quicktime and Windows Moviemaker, but none of them will open.
I read in another thread
"Your card is almost certainly formatted as FAT32, and there are some aspects of deleted files that make recovery of an intact file quite difficult.
In a file's directory entry there is a field holding the address of the file's first cluster. In the FAT there is a chain of cluster addresses linked off this first address, all the way to 0xFFFFFFFF for the last entry. When a file is deleted all the entries in the FAT are set to zero. This is the only way that FAT can tell if a cluster is in use or not.
When the card has had some use the chances of the clusters being contiguous, especially on a large file, reduce. As the cluster addresses of deleted files have been zeroed, it is not possible to retrieve more than the first extent of a fragmented file.
The first cluster address is still held in the directory, so Recuva will retrieve that and all following clusters until a non-zero FAT entry is reached, or EOF as indicated in the directory.
Your failure to play the recovered movies may be that they are truncated, Does the file size look OK, or less than you expected?
FAT32 may also corrupt the first cluster address, depending on how Nikon have implemented it, which makes it even worse."
I've got the same problem, and have verified that the card did store it all as fat32 is there any way to resolve this issue or am I just pretty much screwed? It was able to make sense of two of the video files (Maybe because they're shorter?) It was all filmed in 3 minute clips (This is from an action cam sjcam4000 to be specific) The file sizes all look about right (anywhere from 300 to 450 mb probably dependent on where i stopped each clip) is this good, bad, or pretty much what you expected? I saw in another thread if you pull up the corrupted file in what I think is a video editing software it might be able to regenerate a header and make it playable again? (link to other thread here https://forum.piriform.com/index.php?showtopic=46744&hl=corrupt&do=findComment&comment=275052 called avidemux ) So I did this and it just pops up with an error "Cannot find demuxer unable to open file" Willing to pay a few bucks to resolve this but I also read upgrading to pro won't resolve my specific issue =/ Thanks in advance!
