I am using DeviceIoControl with IOCTL_STORAGE_QUERY_PROPERTY to retrieve StorageAdapterPhysicalTopologyProperty. When i try this i get an 1117 error, "The request could not be performed because of an I/O device error". I have determined that the request succeeds if i use a return buffer defined to be the sizof(STORAGE_DESCRIPTOR_HEADER), but it fails when i use the proper (to me) buffer size of sizeof(STORAGE_PHYSICAL_TOPOLOGY_DESCRIPTOR). When i use the STORAGE_DESCRIPTOR_HEADER, the returned Size and Version is 56 which is the size of the STORAGE_PHYSICAL_TOPOLOGY_DESCRIPTOR, but it's not the data I'm looking for. I have successfully done other Storage Property Queries, but no documentation seems to exist for this property.
This code returns an error on the first DeviceIoControl. But it works if the requested length is 8 bytes.
bool GetAdapterPhysicalTopology()
{
bool result = false;
HANDLE hDevice = CreateFileA(_T("\\\\.\\PhysicalDrive0"),
0,
FILE_SHARE_READ | FILE_SHARE_WRITE,
0,
OPEN_EXISTING,
0,
0);
if (hDevice != INVALID_HANDLE_VALUE)
{
STORAGE_PROPERTY_QUERY query = {};
query.PropertyId = StorageAdapterPhysicalTopologyProperty;
query.QueryType = PropertyStandardQuery;
STORAGE_PHYSICAL_TOPOLOGY_DESCRIPTOR sptd = {};
DWORD bytesReturned = 0;
if ((result=DeviceIoControl(hDevice, IOCTL_STORAGE_QUERY_PROPERTY,
&query, sizeof(query),
&sptd, sizeof(sptd),
&bytesReturned, NULL)))
{
if (bytesReturned)
{
std::vector<char> buff(sptd.Size); // STORAGE_PHYSICAL_TOPOLOGY_DESCRIPTOR
if ((result=DeviceIoControl(hDevice, IOCTL_STORAGE_QUERY_PROPERTY,
&query, sizeof(query),
buff.data(), buff.size(),
&bytesReturned, NULL)))
{
// Get the data...
PSTORAGE_PHYSICAL_TOPOLOGY_DESCRIPTOR psptd = (PSTORAGE_PHYSICAL_TOPOLOGY_DESCRIPTOR)buff.data();
wprintf(L"NodeCount: %d\n", psptd->NodeCount);
// etc
}
else
{
printf("DeviceIoControl(2) failed. Error Code %d.\n", GetLastError());
}
}
}
else
{
printf("DeviceIoControl(1) failed. Error Code %d.\n", GetLastError()); // Gives me error code: 1117
}
CloseHandle(hDevice);
}
return result;
}

I cannot reproduce but my error code is 1. I'll consult.
Update: It's more about Windows Driver Development. Please consult the driver author.
Supposedly it's available at the desktop application layer. According to the documentation it uses winioctl.h and ntddstor.h is not required. So, who is the author - Microsoft!
