Hello Ottoga,
   that sounds right. It looks like an encryption. Didn't know ML had that function. Do you think it is reversible ?

thank you

After posting the thread in the not most appropriate category, I'll paste the discussion here, with the hope that someone has a clue of what happened.

Thank you very much in advance.

File Issue Canon 5D Mark II / 5D2
« Reply #217 on: December 09, 2014, 09:24:58 PM »

Hello everyone
   I hope I am posting this issue in the right place.
My 5D2 with magic lantern for 2.1.2 stable version went mad during the last weekend.
I was taking holiday pictures both in jpeg and raw. Done before, no problems there.
Until, half way of the first day (out of 3 days out shooting without having the chance of connecting to a computer) all the photos disappeared.

I continued using the camera and all the photos taken after the problem made it home safely. Those taken before turned into this (see picture in link)
https://drive.google.com/file/d/0BxMhN5xHDaQVYlU3T01lV0dNdGs/view?usp=sharing

The files are all there, but corrupted, or to better say, encoded with some ML language. In fact every file has a random size from few to hundreds GBs.

What could have happened? I'm always very careful in switching the camera on and off, or opening the CF card slot, or taking the battery out.

and most of all, DOES ANYONE (forum members or developers) have a clue what could have caused the issue or how to recover those images, if possible at all?

Thank you for your help and this space to share our problems.
Alex

This thread mainly deals with Raw Video related issues , General Chat --> http://www.magiclantern.fm/forum/index.php?board=26.0
may be a better place.
But if you tell use more about your camera setting, ML Nightly Build date (if use )
Transfer file but tether cable usb or Card reader ?
CF card speed ?
We could help more , But as a 5D2 user with magic lantern installed for the last Year and a Half I never seen this issue .
Are you Just using the stable release version with out nightly builds ?

Looks like there was some problem with the filesystem. I recommend formatting your card from the camera before each important shoot.

I had this error on 550D, before installing ML.

@reddeercity: General Help Q&A is a much better place; General Chat is fine for offtopic stuff. For RAW video, this is the proper place to discuss things: http://www.magiclantern.fm/forum/index.php?board=49.0

(FYI, ML is not only about RAW recording)

Thank you all for the interest.
  So, I'm using the stable version of ML for 2.1.2 firmware. I copy my files with a card reader. I've been using ML for 6 or 7 months now and never had this issue before. Even if I haven't been using this CF card for photography before (plenty of times for video, though). It's a PNY 100Mbps 32Gb UMDA 7.
What's funny is that the photos where there all the time until photo number 120 (ish) that made the error happen and all the other photos previously taken transformed into those unreadable files. No, i didn't switch the camera off too quickly or remove the card or anything like that. I understand how the camera or the card could mess up one picture, but i don't understand how can all the previous ones (and not the following 300) be compromised.
I'll repost the issue on the General Help Q&A.
Thank you very much.
