A lot of older controllers emulate various forms of the IDE interfaces. They don't support detection/reporting of hotplug events to the OS. Some of them support "warm-plug" - where you tell the controller the device is going to go away, then remove it, then add a new one, then tell the controller. Often they need to execute code when told these things (eg to disable IORDY for PATA devices) -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
