Using Command Prompt (CMD)

Open Command Prompt as Administrator: Search for “cmd” in the Start menu, right-click “Command Prompt,” and select “Run as administrator.”
List disks: Type diskpart and press Enter.
Identify the disk: Type list disk and press Enter. Identify your USB drive by its size. Note the disk number.
Select the disk: Type select disk X (replace X with the disk number of your USB drive) and press Enter. Be absolutely sure you select the correct disk!
Clean the disk: Type clean and press Enter. This will erase all partitions and data on the disk.
Create a primary partition: Type create partition primary and press Enter.

Addressing Size Limitations (for drives larger than 32GB)

Windows built-in tools often struggle to format drives larger than 32GB to FAT32. Here’s how to overcome this:

Use a Third-Party Tool: Several free tools, like Rufus or guiformat, can easily format larger drives to FAT32. Download and install one of these tools.
Select the Drive: In the tool, select your USB drive.
Choose FAT32: Choose “FAT32” as the file system.
Start the Process: Click “Start” to begin the formatting process.

Tips for Formatting USB Drives

Back up your data: Always back up any important data from your USB drive before formatting, as the process will erase all data.
Double-check the drive: Before formatting, double-check that you’ve selected the correct drive to avoid accidentally formatting the wrong one.
Consider Quick Format: For most situations, the “Quick Format” option is sufficient and saves time.
Use third-party tools for large drives: If you’re formatting a drive larger than 32GB to FAT32, use a dedicated third-party tool.
Safely remove the drive: After formatting, always safely remove the USB drive from your computer to prevent data corruption.
