it seems a bit strange because the CurrentDmesg.txt (comment #9) doesn't show the problem. Also I have Trusty Tahr installed and a WD USB3.0 external HDD and I haven't such problems. Either I connect it to USB2.0 or 3.0 port.
It would be helpful if you provide additional information during the connection of HDD.
Open a terminal (CTRL+ALT+T) and write:
watch -n1 "dmesg | tail -n 30"
then connect the HDD and post back here the lines will be produced.
