Okay this routine will check a 1.4MB floppy disk:

Note my corrections to your CreateFile() call.

bool diskIsGood()
{
     HANDLE fileHandle = CreateFile("\\\\.\\a:",
                                    GENERIC_WRITE|GENERIC_READ,
                                    FILE_SHARE_READ,
                                    NULL,
                                    OPEN_ALWAYS,
                                    0,
                                    NULL);

  BYTE buffer[ 512 ];

// Experimental, didn't work. I'm looking into this now.
  DWORD blockTotal=GetFileSize( fileHandle, NULL );

  for( DWORD blockNumber=0;
       blockNumber<2880;
       ++blockNumber )
  {
    SetFilePointer( fileHandle,
                    blockNumber*DWORD( 512 ),
                    NULL,
                    FILE_BEGIN );

    DWORD bytesRead=0;

    if( !ReadFile( fileHandle,
                  buffer,
                  512,
                  &bytesRead,
                  NULL ) )
      return false;
  }

  return true;
}
