On a related topic, is there any way to do anything other than
"surprise" removal with libata?  It'd be nice to put a drive to sleep
(e.g. with "hdparm -Y"), and ensure that nothing comes along and causes
the drive to be reset and spin the drive attached to that SATA port back
up prior to a removal and reinsertion.

I'm assuming that physically unplugging a non-spinning drive is
preferable to unplugging a spinning one from a drive longevity point of
view (I use SATA drives as removable backup medium in some cases).


Unplugging the SATA cable is fine. I wouldn't yank power while it's actively storing data, though.
