New submission from Roman Kozhemiakin:
open('\\\\.\\PHYSICALDRIVE1','rb',0)
fails since python 3.5
At the end of _io_FileIO___init___impl function
_Py_fstat call raise OSError: [WinError 1] Incorrect function
_Py_fstat result not used on windows in this place.
440 self->blksize = DEFAULT_BUFFER_SIZE;
---> 441 if (_Py_fstat(self->fd, &fdfstat) < 0)
442 goto error;
443 #if defined(S_ISDIR) && defined(EISDIR)
444 /* On Unix, open will succeed for directories.
445 In Python, there should be no file objects referring to
446 directories, so we need a check. */
447 if (S_ISDIR(fdfstat.st_mode)) {
448 errno = EISDIR;
449 PyErr_SetFromErrnoWithFilenameObject(PyExc_IOError, nameobj);
450 goto error;
451 }
