Tip: to format the card and remove Magic Lantern, go to the Canon Menu / Format screen and press the shortcut key indicated in brackets, as in the screenshot - on most cameras it's the button.Īfter you open the card door, most cameras will access it during the next few seconds.

We strongly recommend you to format the card before every important shooting session! This helps maintaining performance when recording files, and prevents the filesystem from becoming fragmented.Ī lot of stability and performance issues reported by Magic Lantern users went away after they started to format their cards on a regular basis.įormatting the card from the camera will make sure your file system is exactly as Canon software and Magic Lantern expect it to be. Since Magic Lantern runs from the card, you may be asking yourself: "what happens if I format it"?Īnswer: Magic Lantern first reads all of its required files, including your custom configuration files, and then copies itself back onto the card!
