OK, I think I figured out what caused this. Sometimes unmounting by 
dragging both desktop's drive/partition (FAT32 and HFS+) icons seems to 
get stuck. Mac OS X say it was having problems ejecting and asked me to 
wait or force eject. Before I even saw that message, the desktop's 
mounted drive icons did go away, so I quickly physically disconnected 
the USB2 cable from the MacBook Pro. Then, Mac OS X tells me that I 
didn't eject properly. So I reconnect and manually run Disk Utility app, 
and found a few minor corruptions. :(

Has anyone had this problem before? I see it with this drive and 3.5" WD 
Green desktop HDD with its USB3 adapter on 3 different MBPs (Mac OS 
v10.8.5 (Mt. Lion), 10.10.5 (Yosemite), and 10.12.1 (Sierra)) so far.
