im using a 128g sd card from samsung, the problem im running in to is, im using a 64g image and using the sd card format tool and win 32 disk image writer to put the image on the card, but its only putting whatever size the image is and leaving the rest of the card as an un-allocated partition, is there a way to get the pi to use the rest of the space from inside the image, just not sure what to do, i want to be able to use the entire space available to me to add more roms in the future if i want to.
