Combining high-capacity storage with a slim, lightweight design, this Western Digital 1 TB hard drive provides automatic back up of files in a portable hard drive. The Western Digital My Passport allows users to store as many as 100,000 photos or 250,000 songs. Automatic backup on this Western Digital 1 TB hard drive allows users to work without constantly worrying about the integrity of their files, and password protection guarantees that no one but approved users can access any stored data. Furthermore, this Western Digital 1 TB hard drive can work with either Mac or PC computers and is compatible with a wide range of operating systems. This portable hard drive is self-sufficient as well, and requires no external power. Instead, it receives all its power needs directly through the USB connection to the user’s computer. WD SmartWare also comes standard on the Western Digital My Passport, giving users an easy way to access and organise the files stored on this high capacity external hard drive.
