	Routine Description:

	This routine enumerates the disk devices using the Device interface
	GUID DiskClassGuid. Gets the Adapter & Device property from the port
	driver. Then sends IOCTL through SPTI to get the device Inquiry data.

	Arguments:

	IntDevInfo - Handles to the interface device information list

	Index      - Device member

	Return Value:

	TRUE / FALSE. This decides whether to continue or not
