Received the G1X as Christmas present to self--installed CHDK (hats off to ALL the developers--this is better than ML on my EOS) on a fast 64gb card after forcing FAT32 on it. Enjoy a night time timelapse but went hiking the next day and is my habit I inserted the sd card and formatted it.....and lost CHDK.
When using Magic Lantern the format option keeps Magic Lantern yet formats the card.
Am I missing something with CHDK?
Are you all just 'erasing' pics?
Or do you occasionally format your cards and then re-install CHDK?
