我正在以管理员权限运行以下代码:
HANDLE hDevice = INVALID_HANDLE_VALUE; // handle to the drive to be examined
BOOL bResult = FALSE; // results flag
DWORD junk = 0; // discard results
hDevice = CreateFileW(L"\\\\.\\PhysicalDrive0", // drive to open
0, // no access to the drive
FILE_SHARE_READ | // share mode
FILE_SHARE_WRITE,
NULL, // default security attributes
OPEN_EXISTING, // disposition
0, // file attributes
NULL); // do not copy file attributes
if (hDevice == INVALID_HANDLE_VALUE) // cannot open the drive
{
std::cout << "invalid handle" << std::endl;
return -1;
}
std::cout << "handle " << hDevice << std::endl;
DRIVE_LAYOUT_INFORMATION_EX drv_layout_info_ex;
CREATE_DISK disk;
INT n;
ZeroMemory(&disk, sizeof(CREATE_DISK));
disk.PartitionStyle = PARTITION_STYLE_MBR;
disk.Mbr.Signature = 0x7B060725;
bResult = ::DeviceIoControl(hDevice, IOCTL_DISK_CREATE_DISK, &disk,
sizeof(CREATE_DISK), NULL,
0, &junk, NULL);
if (!bResult)
{
std::cout << "IOCTL_DISK_CREATE_DISK failed due to " << GetLastError() << std::endl;
return FALSE;
}
我得到输出:
handle 00000048
IOCTL_DISK_CREATE_DISK failed due to 5
这是拒绝访问。问题是什么?
