I am only a beginner at Linux-OS's so take this into consideration when you answer this question. I have noticed that my 32G SD card is partitioned into two sda# drives but I need to max out this device for 3D designs and I would like to partition the 32G SD into 6 sda# drives where 1=>2 are as formatted, but 4=>6 are different sizes(3.5,4,8,16). Is this possible.
You can definitely partition the SD as you desire. You will need
gparted to accomplish your goal.
gparted to create an extended partition. Inside the extended partition, create as many logical partitions as you need.
You can only use
gparted to modify unmounted partitions. If you are going to use your Raspberry Pi to modify the SD card, you will need a second SD card to boot from and an SD card reader for the 32 GB SD card.
Make sure that all partitions on the 32 GB SD card are unmounted by looking at the output of
mount. You can use
fdisk -l and
blkid to identify which card is the 32 GB SD card.
