In the instructions for installing the firmware updates it states to provide a formatted card. The question I have is, formatted with the computer or with the camera? I have tried both ways and receive different results. With the camera formatting, besides the update file, I also receive a DCMI file. If I format with the computer I receice the update file only. Which is the correct formatting? Why do I even get a DCMI file? I would appreciate your help on this, thank you.
