WD's Sync Software is not available on a disc, but rather is pre-installed on the Passport drive. You have to create a profile during the installation, for which you need to define a password. Then you'll go ahead and define files for synchronization. These may be email or office files, as well as browser settings and bookmarks. It is also possible to go to the advanced options and make personalized choices, like selecting certain folders manually. All files will be encrypted using a 128-bit AES algorithm. There is an option to select automatic synchronization once the drive is plugged into a USB port.

If you happen to erase the software accidentally you'll have to register with WD, providing your address and phone number. You'll have to insert your drive's serial number and answer a five-question questionnaire. We think that's a little too much information to ask in order to retrieve your synchronization software.
