Like many USB-only drives, on older laptops the My Passport may not be able to draw sufficient power to operate from the bus alone, and so an auxiliary cable may be necessary-it’ll cost an extra $10 from Western Digital. The drive gets a bit hot as the fanless aluminum case works to draw heat away from the drive mechanism, but the upside is that the drive ran quietly throughout our tests. But for all the abuse, the drive didn’t slow down a bit and showed little wear. With 256-bit AES hardware encryption, this portable drive lets you create a password to keep your data private.

It comes with a massive 5TB storage capacity to store all your games, movies, music, and other important files at up to 5,000Mb/s speed. Make sure you tick the checkboxes 'Hard Disks' and 'External Disks.' Your WD My Mac Passport drive should now be running on your screen. I put it through our series of handling tests, which include tossing the drive around my cubicle and dropping it to the ground several times to see how it handles the punishment. Backup your valuable data and access it anywhere with this WD My Passport Ultra external hard drive. If your My Passport drive doesn't turn up for some reason, click on 'Finder', then select 'Preferences'. The My Passport is a simple, light drive. With a 500GB capacity, a three-year warranty, and a shock-resistant shell that can withstand your average wear and tear, the My Passport is one of the best portable drives we’ve seen for the Mac. Western Digital’s My Passport For Mac is a solid, compact, comparatively speedy little USB-only portable hard drive that also happens to be Time Machine–ready and designed for the Mac.
