Recovery of video files .flv after a small dd wipe.

#1 Post by raspberry » 02 Sep 2016, 01:27

I'd first like to say thanks for making this wonderful tool and being active on these forums to help people.

1TB mechanical drive. I overwrote the first 10gb of the drive with /dev/zero "sudo dd if=/dev/zero of=/dev/sdb" (Yeah I did a woopsie).
I tried using disktest but failed to open the file system after the deeper scan, so I looked at photorec.

I don't care about anything on the drive, except my video files. all in mp4 or flv containers.
I got the mp4 videos back fine (Thank you so much), but It seems like every .flv file is cut down to a max of 200MB, 209715200 bytes. Exactly 200MB.
Here's a paste of all the .flv files http://pastebin.com/raw/M8N0D80K
I know that these files were much bigger than 200MB and if you could help me recover the entire files would be a massive breather.

Thanks for your time.

Looks like I'm getting bigger file sizes now, thank you very much.

Thought of a simple feature that would be great, dividing the read and total sectors so you get a percentage of how many sectors were read. Though I guess you do have the elapsed and estimated time there.

Code: Select all

ls -lah | grep G
total 20G
