How To Partition An SD Card?

SD card is a storage device that can be used in many devices like cameras, cellphones, and other handheld devices. When you root your android device or try to install custom ROMs etc., on your SD card, you will need an extra partition for this purpose, and for that, we will use MiniTool Partition Wizard Home Edition. 

This software works on 32 bit and 64 bit Windows operating systems, including Windows XP, Vista, 7, 8, and 8.1. We at Gizmostorm tested the software personally on all of these operating systems without any glitches.

Benefit Of SD Card Partition

Several Android users have been reporting that their SD card has been mounted as Read Only. This is a known bug with 4.4 Kitkat, and the developers cannot fix it. The only solution to fix this problem is to format your SD card and create a new partition from an app like MiniTool Partition Wizard Home Edition.

 Here are some of the benefits you can have from creating a new partition on your sd card:

Increase Memory Space. You will increase the memory space available to you, which means you can install more apps on your device without making any changes to your Android system files or breaking any laws.

Can Store More Data. You can store more data on your sd card without worrying about low memory available errors.

Data Can Be Backed Up Easily. You can back up your data more efficiently by dragging and dropping it onto the new partition on your sdcard drive or using android file transfer apps.

How To Create An SD Card With Extra Partitions? (Without Using CWM/TWRP)

  1. First of all, download the latest version of MiniTool Partition Wizard Home Edition. There are two versions available. One is free, and another has some extra features compared to the free version. Hence it costs some money. But for creating an SD card with multiple partitions, the free version will do fine.
  2. After downloading, open up the folder where you have saved the setup file and run it by double-clicking on its icon. It’ll take a while to install but don’t worry. It’s routine as we use software that requires too many files to be placed in your system, so wait until everything is installed correctly and click on the Finish button when prompted.
  3. Insert your SD card into your PC’s card reader if it is not already inserted. Launch MiniTool Partition Wizard Home Edition. Right-click on your SD card under device manager and select the “Create partition” option, or just press the Ctrl+M shortcut key to open this sub-menu.
  4. In the create partition window, select the “Create As” option as “Primary” and click on the “Create” button. You will notice a new “Unallocated space” has been created under your memory card.
  5. Right-click on it and select “Create Volume.”
  6. Enter a volume label in the textbox provided and press enter. You have to format this newly created volume using the FAT or NTFS filesystem by selecting from the list of options at the bottom left corner of this window. 

If you want to use it for installing custom ROMs, then go with VFAT; otherwise, choose NTFS if you wish to store big files over it, like videos or large games files.

  1. Finally, click on the apply button to execute all the above changes and create your SD card with extra partitions for the memory card. Reboot your system to see the changes.

That’s all. You’ve successfully created an SD card with multiple partitions for better memory management.

How To Create An SD Card With EXTRA Partitions (Using CWM/TWRP)

If you are using either ClockworkMod recovery or Team Win recovery, then it’s not needed to format your sd card manually. You can use this option within these custom ROMs themselves, which will do the same process without any error. 

  1. For example, TWRP recovery has an option called “Partition SD Card,” where you need to select the 1st option known as “1 Partition (EXT4, >200MB, flashable),” which is nothing but a mini tool partition option.
  2. Once you select this option and apply it, your sd card will be formatted and ready to go. You can use it as extra memory for your mobile device or install an Android system on it. It’s also possible to run apps from that partition when using a custom ROM like CyanogenMod CM7, which is famous for its support in the latest android mobile phones and tablets.

Note: You can create as many partitions as you need but keep in mind that too much partition on your SD card will slow down its read/write speed.


With the help of the above tutorial, it’s possible to create an SD card with multiple partitions effortlessly. It’ll take a while when you are running the process for the first time, but from next time onwards, it’ll be done in less than 5 minutes if you’re well aware of how Android works.
