Western Digital Store offers its factory-refurbished Western Digital My Passport 500GB 2.5" Portable USB 3.0 External Hard Drive in Black, model no. WDBKXH5000ABK-NESN, or White, model no. WDBKXH5000AWT-NESN, for $34.99. Coupon code "OUTLET14" bags free shipping. That's tied with last week's mention as the lowest total price we've seen for this drive. (It's also $20 under the best price we could find for a new unit.) It features automatic, continuous backup and password protection. A 6-month Western Digital warranty applies.
