CreateFile打开磁盘格式要求

HANDLE CreateFile(
  LPCTSTR lpFileName,
  DWORD dwDesiredAccess,
  DWORD dwShareMode,
  LPSECURITY_ATTRIBUTES lpSecurityAttributes,
  DWORD dwCreationDisposition,
  DWORD dwFlagsAndAttributes,
  HANDLE hTemplateFile
);
Parameters
lpFileName
[in] Pointer to a null-terminated string that specifies the name of the object, such as file, COM port, disk device, or console, to create or open.
If *lpFileName is a path, there is a default string size limit of MAX_PATH characters. This limit is related to how the CreateFile function parses paths.

When lpFileName points to a COM port to open, you must include a colon after the name. For example, specify COM1: to open that port. When using IrCOMM, specify COM3:.

在msdn查找CreateFile打开磁盘时对lpFileName的说明不太清楚，特此说明一下，CreateFile打开磁盘时，lpFileName的格式必须为"\\\\.\\C:"(打开C盘)，"\\\\.\\D:"(打开D盘)
程序如下：访问C盘

hFile = CreateFile("\\\\.\\C:",
                       GENERIC_READ|GENERIC_WRITE,
                       FILE_SHARE_READ,
                       NULL,
                       OPEN_EXISTING,
                       0,
                       NULL);
