Formatting a New Card
If you have installed a new, never-before-used microSD Memory Card into your NOOK, a dialog box appears, re-
porting that the SD Memory Card is unformatted and that it needs to be formatted.
To format the memory card, do this:
1. Tap the Format Now button to format the memory card.
Your NOOK displays a warning that formatting the memory card will erase its contents.
2. Tap the Format Now button again to confirm that you want to format the memory card.
