What exactly do you want to know? As long as the disk is parked, you can do no I/O on it, i.e. no swapping is possible. Since I don't know anything about the implementation of raids and don't have a raid setup here, I can't really tell how a raid device will behave exactly when one of its disks has been parked. Generally, all I/O will be delayed until the disk is unparked again. > 2. you said it has no value for servers ? did you try ? Again, I'm not quite sure what you want to know. Obviously, desktops or servers for that matter can have disks installed that support the unload feature. On these devices you can use the interface as described in my document. All I'm saying is that the interface has been designed with laptops in mind because I don't see in which situation immediate head unloading would be required or even desirable in a classical server environment.
