IOCTL_STORAGE_QUERY_PROPERTY IOCTL (winioctl.h)

Windows applications can use this control code to return the properties of a storage device or adapter. The request indicates the kind of information to retrieve, such as the inquiry data for a device or the capabilities and limitations of an adapter. IOCTL_STORAGE_QUERY_PROPERTY can also be used to determine whether the port driver supports a particular property or which fields in the property descriptor can be modified with a subsequent change-property request.

BOOL DeviceIoControl(
 _In_ (HANDLE) hDevice, // handle to a partition
 _In_ (DWORD) IOCTL_STORAGE_QUERY_PROPERTY, // dwIoControlCode
 _In_ (LPVOID) lpInBuffer, // input buffer - STORAGE_PROPERTY_QUERY structure
 _In_ (DWORD) nInBufferSize, // size of input buffer
 _Out_opt_ (LPVOID) lpOutBuffer, // output buffer - see Remarks
 _In_ (DWORD) nOutBufferSize, // size of output buffer
 _Out_opt_ (LPDWORD) lpBytesReturned, // number of bytes returned
 _Inout_opt_ (LPOVERLAPPED) lpOverlapped // OVERLAPPED structure
);

Remarks

The optional output buffer returned through the lpOutBuffer parameter can be one of several structures depending on the value of the PropertyId member of the STORAGE_PROPERTY_QUERY structure pointed to by the lpInBuffer parameter. These values are enumerated by the STORAGE_PROPERTY_ID enumeration. If the QueryType member of the STORAGE_PROPERTY_QUERY is set to PropertyExistsQuery then no structure is returned.
