Camera Button Format Method
This is the fastest method to format the memory card, and is a
no-brainer for the D300. For the D300S, it is a little more
complicated since it only formats the current primary card
slot and not the secondary.
You can select the secondary slot instead, as I’ll describe in
the upcoming step-by-step method. Figure 5-4 shows the
buttons and Control panel screens used to format the card.
Notice how these two buttons are marked with the red
FORMAT symbol. Make sure that any pictures on the
memory card have been saved. To do the actual formatting
process, you’ll follow these steps:
1. Hold down the Delete and MODE buttons at the same
time (Figure 5-4, images 1 and 2), until For starts
flashing on the Control panel (Figure 5-4, image 3, red
arrow).
▪ D300S: While you’re still holding down the two
buttons and For is flashing, you can rotate the Main
command dial with your thumb to select either the
SD or CF card slot. It’s a three-finger operation, but
it’s easier than it sounds. You can see in Figure 5-4,
image 3 that I’ve selected the SD card slot for
formatting.
