Please edit your post. Remove your Email address and add some detail. What drive are you trying to format? Your system drive, another internal drive, an external HDD, or a flash drive? The answer can be different, depending.
If it's a new USB flash drive, there is a lovely utility to make sure that it is not "short" of memory. If it's advertised as 16 GB, but only has 8 GB, the format will fail.
