Western Digital offers its factory-refurbished Western Digital 2TB My Book Essential USB 3.0 External Hard Drive, model no. WDBFJK0020HBK-NESN, for $69.99 with free shipping. That's tied with our mention from two weeks ago as the lowest total price we've seen. (It's $4 under the best deal we could find for a refurb elsewhere and $23 less than you'd pay for a new one.) It features WD SmartWare Pro automatic backup software and password protection with hardware encryption. A 6-month Western Digital warranty applies.
