+ *
+ * @remarks
+ * The returned information is mostly related to Sony Memory Stick devices.
+ * On Vista+ the returned information is disk sector size and volume length in
sectors,
+ * regardless of the type of disk.
+ * ReactOS implementation returns DEVICE_HOTPLUG flag if inspected device is a
hotplug device
+ * as well as sector size and volume length of disk device.
