Try the following. Open an elevated Command prompt. Type CMD in the Search box Right Click > Run as Administrator
At the prompt type the following. Make sure you back up any data on the USB flash drive as the following will wipe the drive
list disk <enter> Look for the disk number of your attached USB flash drive.
select disk X <enter> Where X is the number of your USB flash drive you found in the previous step (make sure you have selected the USB flash drive and not your HDD
clean <enter> This will delete all partitions on the drive.
convert mbr <enter>
create partition primary <enter> creates a single primary partition on the USB flash drive.
select partition 1 <enter>
format fs=ntfs quick <enter> I am suggesting ntfs because of the 32GB size of flash drive. You can use format fs=fat32 quick if you wish
Edit: Changed sequence of Convert MBR to after clean instead of after create partition. Convert needs to be done on a clean drive with no partitions.
