Step 8: After diskpart successfully created the specified partition, type format fs=ntfs (or format fs=exfat) and press Enter. You're telling diskpart to format the drive with a file system, let it be NTFS, exFAT, etc.
Step 9: At last, assign a drive letter to the newly created partition by typing assign.
