Get drive type with SetupDiGetDeviceRegistryProperty

Question

I would like to know whether i can get the drive information using the

SP_DEVICE_INTERFACE_DETAIL_DATA\'s DevicePath

my device path looks like below

Answer 1

Given your Storage Device Path:

• Open the device using CreateFile
• use DeviceIOControl to issue IOCTL_STORAGE_QUERY_PROPERTY
• this populates STORAGE_DEVICE_DESCRIPTOR structure

• which has a STORAGE_BUS_TYPE enumeration:

  STORAGE_DEVICE_DESCRIPTOR {
    DWORD            Version;
    DWORD            Size;
    BYTE             DeviceType;
    BYTE             DeviceTypeModifier;
    BOOLEAN          RemovableMedia;
    BOOLEAN          CommandQueueing;
    DWORD            VendorIdOffset;
    DWORD            ProductIdOffset;
    DWORD            ProductRevisionOffset;
    DWORD            SerialNumberOffset;
    STORAGE_BUS_TYPE BusType;         //<---------------
    DWORD            RawPropertiesLength;
    BYTE             RawDeviceProperties[1];
  

  }

The different storage bus types are

• BusTypeScsi: SCSI
• BusTypeAtapi: ATAPI
• BusTypeAta: ATA
• BusType1394: IEEE-1394
• BusTypeSsa: SSA
• BusTypeFibre: Fiber Channel
• BusTypeUsb: USB
• BusTypeRAID: RAID
• BusTypeiSCSI: iSCSI
• BusTypeSas: Serial Attached SCSI (SAS)
• BusTypeSata: SATA

So example psueudo-code

STORAGE_BUS_TYPE GetStorageDeviceBusType(String StorageDevicePath)
{
   /*
   Given a storage device path of

      \?\usb#vid_04f2&pid_0111#5&39fe81e&0&2#{a5dcbf10-6530-11d2-901f-00c04fb951ed}

   return its StorageBusType, e.g.:

      BusTypeUsb
   */

   //Open the disk for reading (must be an administrator)
   HANDLE diskHandle = CreateFile(StorageDevicePath, 
         GENERIC_READ,                        //desired access
         FILE_SHARE_READ | FILE_SHARE_WRITE,  //share mode
         null,                                //security attributes
         OPEN_EXISTING,                       //creation disposition
         FILE_ATTRIBUTE_NORMAL,               //flags and attributes
         0);           
   if (diskHandle == INVALID_HANDLE_VALUE)
      RaiseLastWin32Error();

   try
   {
      BOOL res;
      DWORD bytesReturned;

      //Set up what we want to query from the drive
      STORAGE_PROPERTY_QUERY query= {};
      query.QueryType = PropertyStandardQuery;
      query.PropertyID = StorageDeviceProperty;

      DWORD bufferSize;

      // Query for the header to get the required buffer size
      STORAGE_DESCRIPTOR_HEADER header;
      res = DeviceIoControl(diskHandle, IOCTL_STORAGE_QUERY_PROPERTY,
            ref query, sizeof(STORAGE_PROPERTY_QUERY),
            ref header, sizeof(STORAGE_DESCRIPTOR_HEADER),
            out bytesReturned, null);
      if (!res) RaiseLastWin32Error();
      bufferSize = header.Size;

      //Allocate the buffer and query for the full property
      STORAGE_DEVICE_DESCRIPTOR *deviceDescriptor = GetMem(bufferSize);
      try
      {
         //Issue IOCTL_STORAGE_QUERY_PROPERTY to get STORAGE_DEVICE_DESCRIPTOR
         res = DeviceIoControl(diskHandle, IOCTL_STORAGE_QUERY_PROPERTY,
                    @query, sizeof(STORAGE_PROPERTY_QUERY),
                    deviceDescriptor, bufferSize,
                    out bytesReturned, null));
         if (!res) 
            RaiseLastWin32Error();

         return deviceDescriptor.BusType;
      }
      finally
      {
         FreeMem(deviceDescriptor);
      }
   }
   finally
   {  
      CloseHandle(diskHandle);
   }
