Title: Retrieve MLV from formatted CF
Post by: Eggeh on June 01, 2019, 11:41:01 AM
Hey, I've been going through most posts regarding retrieving MLV files from a formatted CF card.
It happened to me in the past but I always managed to retrieve the files via Photorec or Recuva.

Case here is, I formatted the card via Windows 10 and didn't write anything back on it since then. I've been trying to go through Recuva Deep Scan and Photorec 7.1, both softwares don't detect anything, not even corrupted bits of files, like if the card was new. Maybe I'm missing some setting to go deeper? Any help would be appreciated, thanks :)

BUMP!

This happened to me today. Anybody have any advice on recovering MLV files from a formatted card?!?

If PhotoRec doesn't recover the files, this is something I'd like to research, so... create an image of the card (like this (https://thepihut.com/blogs/raspberry-pi-tutorials/17789160-backing-up-and-restoring-your-raspberry-pis-sd-card)), and send it to me.

(I've missed the OP in June, sorry; if it's still valid, just ask)

Indeed, Photorec has worked in the past for me (as long as you run in paranoid mode) although not perfect and don't ask why.  :P

I was able to restore my MLV files from my SD cards on multiple occasions by selecting "Initialize" when the option appears, and "repair disk" in Disk Utility. Then I simply re-insert the SD card, and then they are accessible. This has always worked for me in my case.

Hey it worked!! Somewhat. Thank you so much!

It recovered about 90% of the files. Unfortunately, there was 3 main shots that couldn't be recovered so we have to reshoot the entire sequence anyway. Thank you so much for this!

@A1ex I've already written back to the card at this point, but I can easily format a card just so that you can experiment with (maybe that would defeat the purpose).
