At least in theory, any pnp device could be hotplugged. Of course it depends on which protocol the ide drive is represented by. ISAPnP is completely static where as PnPBIOS, and potentially ACPI in the future, support docking stations and other removable pnp devices. Support for PnP hotplugging is very limited at the moment however it is best to design drivers around this feature so we don't have a mess when PnP hotplugging is finally used. Also if a pnp protocol was presented in a removable module format, the protocol may want drivers to detach from its devices upon module unload. Are there any other hotpluggable ide devices and if so how are they handled?
Also any additional comments?
