QuestionReading sectors Pin

I have written a little piece of code to read few (first 512) bytes from USB drive. here is the code:
HANDLE hVolume = ::CreateFile(sVolume, GENERIC_READ,
    FILE_SHARE_READ | FILE_SHARE_WRITE,
    NULL, OPEN_EXISTING, FILE_FLAG_SEQUENTIAL_SCAN, NULL);
TRACE("Volume handle: %p\n", hVolume);
LONG lDistLow = 0;
PLONG plDistHigh = 0;
if (INVALID_SET_FILE_POINTER == SetFilePointer(hVolume, lDistLow, plDistHigh, FILE_BEGIN) &&
    NO_ERROR != GetLastError())
{
    TRACE("Error: %d\n", GetLastError());
    return FALSE;
}
else
{
    TRACE("%d\t%d\n", lDistLow, plDistHigh);
}

DWORD dwLen = 512;
DWORD dwNum = 0;
void* pBuffer = NULL;
ReadFile(hVolume, pBuffer, dwLen, &dwNum, NULL);
TRACE("%p\t%d\t%d\n", pBuffer, dwLen, dwNum);

but the result is:
Volume handle: 00000438
0	0
00000000	512	0

this pBuffer NULL tell me that I am not able to read that sectors ... why ? The program is running as admin and sVolume is feed by _T("\\\\.\\F:"), first TRACE macro printed is a prove that is OK that part. SetFilePointer is used to position the reading part, and I intend to setup offset to the beginning, right ?
