Hi, I'm Anvar, I'd be glad to help you today on this
If FAT32 option not showing in format , suggest to use diskpart command line tool
kindly fellow below steps
- Type cmd in windows search ad right cick on it and click run as administrator
- Next you can type the command diskpart in Command Prompt window. Press Enter to launch DiskPart utility.
Then you can type the command "list disk", press Enter and all detected disks will be displayed with detailed information. Check carefully which disk is your USB drive. You may identify the USB by checking the size. n this example we are assuming it as disk 3
Step 4. Select and clean the target USB drive
Type the command "select disk 3" and press Enter to select the target USB flash drive. Then type "clean" command and press Enter. DiskPart will wipe disk data.
Step 5. Format USB flash drive/pen drive with CMD (Command Prompt)
Tip: Before you format USB using CMD, you can confirm again that you’ve selected the right disk, to avoid formatting the wrong disk. You can type list disk command again, press Enter, and the selected disk should have a “*” mark before the disk number.
After that, you can type the command create partition primary, and press Enter.
Then type the command "format fs=ntfs" or "format fs=fat32", and press Enter to format the USB flash drive to NTFS or FAT32 format. Optionally you can add a “quick” flag after the command for a faster format.
Step 6. Assign a drive letter for the USB
Continue to type the command "assign letter=h", replace “h” with the preferred drive letter you want to assign to the USB drive. Press Enter to assign a letter for the USB drive and make it visible in Windows File Explorer.
Type exit to close DiskPart and type exit to close Command Prompt window.
After formatting the USB flash drive in CMD (Command Prompt), the USB drive should be shown in Windows File Explorer and is available for storing files
Note :_ Exlude quotes while typing commands
