$a = DllCall("fmifs.dll", "long", "FormatEx", "wstr", 'G:\', "dword", 11, "wstr", "NTFS", "wstr", "", "bool", True, "dword", 0, "ptr", 0)
MsgBox(0,@error, $a[0])
_ArrayDisplay($a)

TheFormatEx function in FMIFS.DLL is prototyped like this:

VOID FormatEx ( PWCHAR DriveRoot,
   DWORD MediaFlag ,
   PWCHAR Format,
   PWCHAR Label,
   BOOL QuickFormat,
   DWORD ClusterSize,
   PFMIFSCALLBACK Callback);

where the FMIFSCALLBACK is:

typedef BOOLEAN (__stdcall *PFMIFSCALLBACK)(
   CALLBACKCOMMAND Command,
   DWORD SubAction,
   PVOID ActionInfo );

So your dll calling parameters are incorrect. If you had done a proper websearch, you would instantly have found this site, from which source code (that would have to be adapted for AutoIt) can still be downloaded. The rest is up to you...

I dont see nothing useful on site you linked, but If you meant about C examples where FormatEx is used I already found that and since I dont know to read C I obviously cant adapt it to autoit. Thats why I asked here for help...

You have to set up a dll CallBack for this to work. If you're familiar with PowerBasic, here's a source code example you might be able to adapt. AFAIK, there's no existing AutoIt source code for this particular function on the forums. But someone else may have something lying around, if you're lucky.

Hello. I have not time to see too much. But base in RTFC's first post This could be a start...

 

Local $hHandle = DllCallbackRegister("_PFMIFSCALLBACK", "long", "long;dword;ptr")
Local $pCallBack = DllCallbackGetPtr($hHandle)

DllCall("yourdll.ll", "none", "FormatEx", "dword", $MediaFlag, "wstr", $Format, "wstr", $Label, "bool", $QuickFormat, "dword", $ClusterSize, "ptr", $pCallBack)

DllCallbackFree($hHandle)

Func _PFMIFSCALLBACK($Command, $SubAction, $ActionInfo)

EndFunc   ;==>_PFMIFSCALLBACK
