Formatting an SD card to FAT32 is a common requirement, especially when dealing with larger capacity cards like a 64GB SD card. FAT32 is a file system that is widely compatible with various operating systems and devices. In this article, we will explore the steps to format a 64GB SD card to FAT32 and ensure that it can be used across different platforms.

Step 1: Backup Your Data

Before formatting your 64GB SD card, it is crucial to back up any important data stored on it. Formatting will erase all the data on the card, so it is essential to make sure you have a copy of everything you need. You can transfer the data to your computer or another storage device to keep it safe.

Step 2: Choose the Right Formatting Tool

To format a 64GB SD card to FAT32, you will need to use a formatting tool that supports this file system and can handle larger capacity cards. One popular tool is the “FAT32 Format” utility, which is available for free online. Download and install the tool on your computer.

Step 3: Insert the SD Card

Insert the 64GB SD card into the appropriate slot on your computer or connect it via a card reader. Ensure that the card is properly inserted and recognized by your computer before proceeding to the next step.

Step 4: Run the Formatting Tool

Launch the FAT32 Format utility that you installed in Step 2. The tool should detect the connected SD card automatically. If it doesn’t, make sure the card is properly connected and recognized by your computer.

Step 5: Select the SD Card

In the FAT32 Format utility, you will see a list of available drives. Locate your 64GB SD card in the list and select it. Double-check to ensure you have selected the correct drive, as formatting the wrong drive can result in data loss.

Step 6: Choose the File System and Allocation Unit Size

In the formatting tool, you will have the option to choose the file system and allocation unit size. Select “FAT32” as the file system, as this is the one we want to format the SD card to. The allocation unit size can be left at the default value, as it will work fine for most scenarios.

Step 7: Start the Formatting Process

Once you have selected the file system and allocation unit size, you are ready to start the formatting process. Click on the “Start” or “Format” button in the formatting tool to initiate the process. A warning message may appear, reminding you that all data on the SD card will be erased. Confirm the action and proceed with the formatting.

Step 8: Wait for the Formatting to Complete

The formatting process may take some time, depending on the speed of your computer and the size of the SD card. Be patient and let the tool complete the formatting. Avoid interrupting the process or removing the SD card while formatting is in progress, as it can lead to errors or data corruption.

Step 9: Verify the Formatting

Once the formatting process is complete, you can verify that the SD card has been successfully formatted to FAT32. You can do this by checking the properties of the SD card on your computer. Right-click on the SD card drive, select “Properties,” and navigate to the “File System” section. It should indicate that the file system is now FAT32.


Formatting a 64GB SD card to FAT32 is a straightforward process that can be accomplished using the right tools. By following the steps outlined in this article, you can ensure that your SD card is formatted correctly and can be used across different devices and operating systems.
