Testing out the Nightly.2014Sep01.5D2212 build for a Sporting event tomorrow I need to cover.
every think recorded ok with MLV+Audio but when I did a format in Camera I lost Every thing off the Card
including ML. This has been a problem that has come up in the past .
I have to format with EOScard and reinstall ML.
I Go back to my trusty feb build for now, as I can't have any failures tomorrow.
So be careful with that function .
Hi reddeercity, I´ve got your very valuable help before so maybe I can now bring my two cents here.
I´ve found that after recording RAW, if I immediately try to format the card without restarting the camera, the two following issues come up:
1st Before formatting the card, the actual GB left on the camera showed in the format menu seems wrong, as it was nothing recorded before coming to the format menu.
2nd After formatting, all information in the card is lost including Magic Lantern as it happened to you, and you need to reinstall ML in the card from scratch.
The solution I´ve found for this issue is to always restart the camera after recording RAW if I need to format the card.
After restarting you will also find that the actual GB left on the card, that is showed in the format menu, is ok.
First time it happened I got really scared as I thought my new 32GB card was fried!
So maybe it is not a nightly build problem.
Hope you found it useful.
