Something I've noticed recently: When my link-dest rsync encrypted back 
up to a recent model USB-3 WD disk is done, unmounted, and ready to be 
unplugged...I can still feel it vibrating and doing something.

I've decided this must be some useful housekeeping, and have waited 
until it quieted down.

Anyone know what it is?
