I'm new here and just installed ML on my 60D. The thing works like a charm but I hadn't felt a need to join the forum until after yesterday night after I found a problem. Maybe this problem is known to you all and I have missed it, or maybe it is normal for ML. Either case I found it out the hard way.
I had just shot a short animation sequence using the Audio Remoteshot with ML (that was a great help) and took came home to finally transfer the material to my PC. Everything was alright till then.
I removed the SDHC (8gb lexar class 10) - with all the due precautions and waiting appropriately for opening the card gate after shut down and another 5 seconds after the LED goes out on the gate before pushing to release the card.
I used my notebook's in built card reader to read the card (its the only reader i have and used it to install ML too) and opened up the folder and put the photographs on transfer.
Here's where the problem comes about what I did different from the regular things that I do. I by chance clicked on the ML User Guide pdf that was in the Card's Root and opened it.
the transfer completed and I ejected the card and put that back in the camera. When i turned the camera back on to clear the photos from the card the camera's start screen said "Cannot create folder" - the same message that you get when you do not format your camera after a firmware update or ML install. So I did exactly that and formatted my card while keeping ML on it and it was up and working normally again. To figure out the problem I then had the card back in again and opened the user guide from it again. The same thing happened this too and it was fixed by the format. The card in fact did not give any problems as such until I did not try to open any of the ML files from it and stayed put with opening only the eos100 media folder.
Later after I was done checking this I decided to open the files I had transferred and realised to my horror that not a single one was there in the folder to which I had transferred them to! Thankfully I was able to recover them from the card with some recovery softwares, However I did decide to ask about this over here because of that. I believe that the file deletion came about because I opened the user guide while the transfer happened?
Either way the problem really comes down to this - I figure out that I must not open any of the ML files directly from the card on my pc and that it is a dangerous thing to do?? OR is this some sort of an error occuring of which I need to be more beware of / re-install ML or do a workaround? ALSO, I'm only using the Stable Release of ML (v2.3) and no other version at all.
