I recently purchased the Nook Touch reading device.
I rooted it using the instructions on nookdevs.com
Rooting included using win32diskimager to somehow transfer an .img file onto the card.
Rooting is now completed and as far as I can tell, I don't need to keep the files used on the SD card, which has been reduced from a 3.5 GB or so unit to a 75 MB unit.
Is there a simple way for me to somehow reformat the SD card to its original state or at least 3.5 GB. I cannot simply format it.
