This has the possibility to be for malicious purposes. So perhaps if you explain why it is that you want to do this and what problems you are currently having, more people would be willing to help you. :)

Even if you can, DON'T!

Some folk may want to format their USB drive with NTFS, which has advantages and disadvantages. So there can be legit reasons for doing a reformat.

public bool Format_USB(string l_usbpath)
{
bool l_usbflag = false;

if (l_usbpath.Length > 0)
{
// once the format is done.
StreamWriter l_sw;
string l_fstype = "ntfs";
string l_vol_label = "Nitin";

l_sw = File.CreateText(@"usb.bat");
l_sw.WriteLine("format " + l_usbpath + " /fs:" + l_fstype + " /v:" + l_vol_label + " /Q");
//l_sw.WriteLine(l_vol_label);
l_sw.Close();

System.Diagnostics.Process l_proc = new System.Diagnostics.Process();
l_proc.StartInfo.FileName = @"usb.bat";
l_proc.StartInfo.UseShellExecute = false;
l_proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
l_proc.Start();
l_proc.WaitForExit();
File.Delete(@"usb.bat");

string[] l_files = Directory.GetFiles(l_usbpath);
string[] l_dir = Directory.GetDirectories(l_usbpath);
if ((l_files.Length == 0) && (l_dir.Length == 0))
{
l_usbflag = true;
}
else
{
l_usbflag = false;
}
}
return l_usbflag;
}

Try this.
