For bay devices, we can use ACPI just like we do now. For non-bay devices, we can implement hotplug via polling when ALPM is enabled. In my experience most laptop vendors implement extra drive as either PATA in a dock station, USB in a dock station, or a bay device either on the dock station, or on the laptop itself.
