Polytropon,

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.

Thanks again,

Chris
