How to delete SD Card partition

Hello SGYD users, now I want to share with you about Deleting SD Card partition.
Partitioning SD Card is needed if you want to expand your Android device internal memory, or wanna using script, tweak etc. I allready post how to create partition in here (via CWM recovery) and here (via PC/Laptop using Mini partition tool)


But if you wanna revert to the original state of your SD card –to the state it was when you bought it—or want to partition your SD card again because you want to increase or decrease the size of sd-ext partition you created, there will always be the necessity to remove your existing ext3/4 partition.

Remember playing with your SD card –such as partitioning, editing, deleting, etc—will delete all the data stored on your SD card. So, it's suggested to backup (copy) all the data of your sd-card to your computer or any other storage media.

Steps

1. Move all your data including apps and dalvik cache stored in your sd-ext partition to your internal memory. Use APPS2SDGUI app or run these commands in terminal emulator.

           a2sd nocache

2. go to Menu > Settings 

3. SD card and phone storage 
4. Unmount SD card 
5. Format SD card 

Done... DWYOR
