Thus, you can have your Format both ways by means of toggling Q. If the 'Q' button is pushed it switches to a mode where all data including Magic Lantern are erased. There I found something that I was previously unaware of: the Format page default mode preserves Magic Lantern on the card while formatting the rest of the card. That was a bit of an 'ahah' moment and shows there is occasionally some value to reading the documentation.Īfter that I picked up my t2i and punched up the Canon menu Format page.

"How do I erase all of the images without removing ML?Ĭanon menu -> Format -> Format card, keep Magic Lantern." After reading your post I looked at the ML User Guide and found the following statement. I stated that to avoid erasing ML it was necessary to delete the images from the card using the Canon menu Delete command as opposed to formatting the card. It is, however, not too difficult to add the correct folder back on if it is mistakenly deleted.You do install a ML loader into the camera once, b. Just don't format on your computer as it will remove assess to the ML files. A card with ML on it can be used in another camera without ML, but I would recommend formatting that card on a camera modified for ML. It seems to take a few seconds longer than usual, however. As far as deleting pictures, no problem with doing an in camera format as ML software handles it. You do install a ML loader into the camera once, but ML must be on each of the cards that you intend to use.
