打開物理驅動器。視窗

Question

我嘗試像

ofstream * _fileWriter->open(_destPath, std::ofstream::out | std::ofstream::binary); 

_destPath = \\開放物理驅動器。\ PhysicalDrive1 但是，當我嘗試做

if (!(_fileWriter->is_open())) 
    return false; 

它返回false

Answer 1

你要運行的程序與高架通道。

請求GENERIC_READ/GENERIC_WRITE

hdrive = CreateFile(L"\\\\.\\PhysicalDrive0", GENERIC_READ, 
    FILE_SHARE_READ, 0, OPEN_EXISTING, 0, 0); 

如果你只是想獲得磁盤的信息，您可以打開，沒有讀/寫訪問的磁盤，下面的代碼不應該需要提升權限：

HANDLE hdrive; 
hdrive = CreateFile(L"\\\\.\\PhysicalDrive0", 0, FILE_SHARE_READ, 0, OPEN_EXISTING, 0, 0); 
if (hdrive == INVALID_HANDLE_VALUE) 
{ 
    cout << "error " << GetLastError() << endl; 
    return 0; 
} 

cout << "open" << endl; 
CloseHandle(hdrive);
