Freeing Up Space & Backing Up Data

- Manual Transfer: Access the drive through your device's file manager and move photos, videos, music, documents, and contacts.
- SanDisk Memory Zone App: Download and install the SanDisk Memory Zone app (required for automatic backups). This app allows you to automatically back up your photos and videos, freeing up space on your smartphone.

Maintenance
To ensure optimal performance and longevity of your SanDisk Ultra Dual Drive Go, follow these general maintenance guidelines:
- Physical Care: Keep the drive clean and free from dust and debris. Use the swivel design to protect the connectors when not in use.
- Temperature: The drive may become warm during extended use, especially during large data transfers. This is normal. Avoid exposing the drive to extreme temperatures.
- Safe Removal: Always safely eject the drive from your device before physically removing it to prevent data corruption.
Troubleshooting
If you encounter issues with your SanDisk Ultra Dual Drive Go, consider the following:
- Device Not Recognized:
- Ensure the drive is fully inserted into the correct port (USB Type-C or Type-A).
- For mobile devices, verify that USB On-The-Go (OTG) support is enabled in your device settings.
- Try connecting the drive to a different port or device to rule out port-specific issues.
- Slow Transfer Speeds:
- Ensure your device's USB port supports USB 3.1 Gen 1 or USB 3.0 for optimal speeds. Older USB 2.0 ports will result in slower transfers.
- Large file transfers can sometimes cause the drive to heat up and potentially throttle speeds. This is a normal protective measure.
- Consider reformatting the drive to exFAT for better compatibility and performance across different operating systems, especially if you experience issues with FAT32's file size restrictions.
- Data Corruption: Always safely eject the drive from your operating system before physical removal to prevent data loss or corruption.
