Operating the Drive
Transferring Files
Once connected, your My Passport drive functions like any other external storage device. You can drag and drop files, copy and paste, or use your operating system's file management tools to transfer data.
- Copying Files: Select the files or folders you wish to transfer from your computer, right-click (or Ctrl-click on Mac) and select "Copy". Then, navigate to the My Passport drive, right-click in an empty area, and select "Paste".
- Dragging and Dropping: Open both the source folder on your computer and the My Passport drive folder. Drag the desired files or folders from the source to the My Passport drive.
Using Backup Software
The included software allows you to set up automatic backups of your important data. Refer to the software's help documentation for detailed instructions on configuring backup schedules and selecting specific files or folders.
Password Protection and Hardware Encryption
For enhanced security, the My Passport drive supports 256-bit AES hardware encryption and password protection. This feature is managed through the installed WD software.
- Open the WD software application.
- Navigate to the security or password protection section.
- Follow the prompts to set a password for your drive. Remember this password, as it is crucial for accessing your encrypted data.

Maintenance
Safe Removal

Physical Care
- Keep the drive in a clean, dry environment.

Troubleshooting
Drive Not Detected
- Ensure the USB cable is securely connected to both the drive and the computer.
- Try a different USB port on your computer.
- Try a different USB cable (if available).
- Restart your computer.
- Check your computer's Disk Management (Windows) or Disk Utility (macOS) to see if the drive is recognized but not assigned a drive letter or mounted.
Slow Transfer Speeds
- Ensure you are connected to a USB 3.0 (or higher) port on your computer. USB 2.0 ports will result in significantly slower speeds.
- Avoid running multiple demanding applications during large file transfers.
- Ensure your computer's drivers are up to date.
Forgotten Password
If you forget your password for an encrypted drive, you may lose access to your data. WD software typically provides a password hint or recovery option during setup. If no recovery option was configured, data recovery may not be possible without the correct password.
