Format Drive in Python

Question

I'm attempting to make a Python 3.3 program to format a drive in Windows such as a SD Card or USB Stick. I tried the code here: http://bytes.com/topic/python/answers/537724-formatting-device-script-windows. At first it gave me an error, but after some tweaking it didn't. It ran but nothing happened to my USB Drive. Here's the code I'm using. (This is using the ctypes module btw) Please Help!

def myFmtCallback(command, modifier, arg):
    print(command)
    return 1    # TRUE

def format_drive(Drive, Format, Title):
    fm = windll.LoadLibrary('fmifs.dll')
    FMT_CB_FUNC = WINFUNCTYPE(c_int, c_int, c_int, c_void_p)
    FMIFS_HARDDISK = 0x0C
    fm.FormatEx(c_wchar_p(Drive), FMIFS_HARDDISK, c_wchar_p(Format),
                c_wchar_p(Title), True, c_int(0), FMT_CB_FUNC(myFmtCallback))

I call the function accordingly:

format_drive('F:\\', 'NTFS', 'USBDrive')

And the program prints this:

>>>
9
11

I found the solution! This line:

 FMIFS_HARDDISK = 0x0C

should be like this

 FMIFS_UNKNOWN = 0

That simply makes it format by Unknown!
