Have a 2TB backup drive on which I had stored thousands of FLV videos that played in many Windows OS players. The backup drive was less than 10% full. The wife accidently deleted the folder they were stored in. I used Recuva to recover them which it said it did, although during the process, it changed most of the .flv extensions to .mp4 and when I went to play them I got the message that they are undefined files and unplayable even in a MP4 player. I used Gspot to check this and it indicated they were undefined files. VLC said they were undf files too. Quicktime and many other players I tried either didn't do anything or indicated an error. I tried changing the extension on a few to .flv in dos, but I still could no longer play them. I even tried several flv recover/repair tools and they could not repair the significant damage Recuva has done.
I find it horrendous, that Piriform's Recuva has modified the extensions of files and their content when recovering video files. It now makes me very leery to use Recuva to recover any files as they have no integrity. The files that Recuva found and recovered was stated at 100% and no additional files had been added to the Backup drive prior to the recovery.
I would appreciate a repair utility from Piriform ASAP as they need to standby what they market to consumers. Their Recuva program stated it recovered my video files 100% and did not indicate any issues with the integrity of the recovery files which were modified by Recuva with no mention anywhere in their documentation that they modify files during recovery nor to not use Recuva to recover video files. It's one thing to change the extension which is easy to change back, it is another to also modify the file in such a way that it is no longer playable based on its initial creation format and content.
CAUTION: If you do not see a fix by Piriform in this forum or my update as to a fix that worked, then I would not use their neat tools like Recuva until they do fix it.
