How to partition your SD card from console (This requires the cyanogen recovery 1.3.1+)

Example for my 8GB card.

Reboot and enter recovery (home+power) then go to console. Enter the below pressing “enter” after each line.

parted /dev/block/mmcblk0
print (to verfiy we know what size card we are dealing with. Mine was 8166 read below if yours is different)
rm 1 (if you had more than 1 partition you would want to rm them as well)
mkpartfs primary fat32 0 7622
mkpartfs primary ext2 7622 8134
mkpartfs primary linux-swap 8134 8166

if your card isn’t 8166 when you type print then you will need to modify those numbers to match your card size. You basically work back to figure out the totals. To figure it out, start with your cards total size. For example 8166 total, subtract 32 for swap (8134) minus 512 for ext (7622) the rest will go to fat32. Each partition starts where the other left off.
