With this command
dd bs=4M if=2015-09-24-raspbian-jessie.img of=/dev/sdd
, I am writing an image (https://www.raspberrypi.org/downloads/raspbian/
) about 3.28GB to a 8GB SD card. After the writing, I checked the SD card with the Disk Utility on my Mac, I can only see about 3.2GB of space. So, where did the rest of the space go? How can I recover them so that I can use them in the Raspberry Pi Raspian system?
