Yes, but the point is that it's a cheap and easy test, so you might
as well do it -- just beware of what it does, and most importantly
does not, tell you. It's a valid scenario to test regardless, you
want to be sure that you can yank a disk to replace it, without a
bus hang or other hotplug problem on your hardware.
Agreed. It's also a very effective way of preventing your drive from
responding to commands, to test how the system behaves when a drive
stops responding. Some significant percentage of device failures will
look similar.
