How can you format a 128GB USB flash drive to FAT32

"Hi all, I have a 128GB Corsair flash voyager GT USB 3.0 flash drive. It came formatted as NTFS. Recently, I wanted to format it to FAT32 in order to use it in my other electrical goods like My Xbox and my TV. But when I plugged the flash drive into my computer and tried to format the USB to FAT32, it would not let me do it. I am just wondering why it happened and how can I successfully format my 128GB USB flash drive to FAT32. If you have any suggestions, please help!"

Why do you want to format 128GB USB flash drive to FAT32 

FAT32 is a file system used by Windows PC, USB flash drive, microSD card, pen drive, memory sticks, and other devices.

1. FAT32 is widely compatible with various operating systems. (smartphones, tablets, computers, digital cameras, game consoles, surveillance cameras, etc.) Compatibility is the main reason for using the FAT32 file system on USB or SD cards.

2.NTFS and other file systems do not support NAS devices.

3. Most game consoles like PSP, PS3, PS4, Xbox only support disks or USB drives with the FAT32 file system.

You may find that it just doesn't give you the option for the FAT32 file system. What leads to the error?
