How to Format a microSD Card to FAT32 from Windows Using CMD (Command Prompt)

Updated

Some Nexxt Home smart cameras may have trouble recognizing or properly recording to a microSD card when it is formatted with the exFAT file system.

In these cases, it is recommended to format the card to FAT32, as it is the file system with the greatest compatibility for our devices.

This article explains how to perform the formatting using the Windows Command Prompt (CMD).

> Important: This procedure will erase all information stored on the microSD card. Please back up your files before continuing.

Before You Begin

You will need:

  • A Windows computer.
  • A microSD card reader.
  • The microSD card you want to use.

Step 1. Insert the microSD Card

Insert the microSD card into your computer’s card reader.

Wait for Windows to detect it properly.

Step 2. Open Command Prompt as Administrator

  1. Press the Windows key.
  2. Type:
cmd
  1. Right-click on Command Prompt.
  2. Select:

Run as administrator

Step 3. Open DiskPart

Type the following command:

diskpart

Press Enter.

Step 4. List Available Disks

Type:

list disk

You will see a list similar to:

Disk 0    476 GB
Disk 1     64 GB

Identify which one corresponds to your microSD card.

Important: Carefully verify the disk size before proceeding.

Step 5. Select the Card

If the card corresponds to Disk 1, type:

Step 13. Reinsert the microSD Card into the Camera

  2. Open the Nexxt Home app.
  3. Go to:

Settings → Storage Card

  1. Verify that the camera properly recognizes the card.

How to Verify It Is Formatted as FAT32

In Windows:

  1. Open This PC.
  2. Right-click on the card.
  3. Select Properties.

Under File System it should show:

FAT32

What to Do If Windows Says It Cannot Format to FAT32

Windows has a limitation that prevents formatting some cards larger than 32 GB to FAT32 using File Explorer.

In these cases:

  • Use the procedure described above with DiskPart.
  • If the command format fs=fat32 quick does not work due to the card size, you will need to use a third-party tool that allows formatting large drives to FAT32.

Is There a Demonstration Video on How to Format a microSD to FAT32?

Yes, there are many tutorials, articles, and demonstration videos online that can help you. Youtube.com is a good place to find this information.

Recommendations

  • Use microSD cards from reputable brands.
  • Make sure the card capacity is compatible with your camera model.
  • After formatting, allow the camera to initialize the card before starting to record.
  • If the camera still does not recognize the microSD, try another card to rule out a physical defect.

Important Note: Although many new microSD cards come factory-formatted in exFAT, some Nexxt Home camera models may have trouble recording properly in this format. If you experience ongoing recognition or recording issues, we recommend using FAT32, as it offers greater compatibility with our devices.
