Originally posted by foxhead On my K-5 I have set custom setting 24 to save the last menu location. Since I rarely go to the menus, and I always reformat the SD card after I've transferred the files, the menu button usually opens at the format function. I'm not sure if this is the best way to easily reformat on a K-1, but it works for me on the K-5.
I believe this would be the fastest solution. Not exactly what the OP asked for but the best available method. I shudder just a bit at having a dedicated 'format' button. I am quite confident I would manage to press that by accident.
I also format a card every time it goes into the camera. And I have the menu set to 'stick' as @foxhead suggests. So it is just a couple button presses most of the time. And if more, well I think formatting should be something done with deliberation and intention, not a casual button press. YMMV.
