Thank you. I've been doing the same... but I assumed/hoped there was
more I could do. I also shutdown smartd before pulling the drive, and
start smartd afterwards. I hope there are not others. ("hope" is a
common theme here... which is why I'm writing to the list)
I didn't know that the heads were parked when the power is cut... but
that is a relief to hear.
