Cons
- ✗ Requires reformatting before use on Mac OS X - not cross-platform out of the box

Manufacturer description
The WD My Passport 1TB portable external hard drive is Western Digital's palm-sized answer to running out of laptop storage. Connection is over USB 3.0, with USB 2.0 backward compatibility if you are plugging into older machines. Two software features do the heavy lifting: the included WD Backup utility runs scheduled automatic backups so your files copy themselves without you remembering to, and built-in password protection with hardware encryption locks the drive if it walks off. The My Passport ships formatted for Windows 10, Windows 8.1, and Windows 7; Mac users need to reformat before…
SpecPicks Verdict
SpecPicks scored Western Digital WD 1TB Blue My Passport Portable External Hard Drive using a rating × review-volume × price-fit model applied to published specs and reviews across the external storage category. Western Digital's external storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for external storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Does the WD My Passport 1TB work with a Mac?
Not out of the box. It ships formatted for Windows 10, 8.1, and 7, and Western Digital specifies that it requires reformatting for Mac OS X. Reformatting erases the drive, so do it before copying files over.
Does it need a separate power adapter?
No. The My Passport is bus-powered over its USB 3.0 connection, so the single cable carries both data and power from your computer.
How does the password protection work?
The drive includes password protection backed by hardware encryption, so the data is locked at the drive level rather than by a software layer on your PC. Set the password through the bundled WD software.
What warranty does Western Digital provide?
Western Digital covers this My Passport with a 3-year manufacturer's limited warranty. Check the product listing for the current terms and registration requirements in your region.
Will it work with a USB 2.0 port?
Yes. The drive uses a USB 3.0 port but is USB 2.0 compatible, though transfer speeds will drop to USB 2.0 rates on the older connection.
