Yes.  There's no documentation on how to do it because it "just works."

If the sata controller supports it, it is just as easy as usb.  Onboard 
controllers may not.  You'll know you got a lemon controller when the 
machine locks up.

>perhaps with some "hdparm" action before and after?

If your controller doesn't hotplug, the 'warmplug' mechanism seems to be 
`scsiadd` -- though you only really get to add it.  I think I managed 
to remove a drive from my junky onboard controller once without the 
machine hanging, but repeated warmplugging seems unstable.
