- Extend the USB-C connector from the flash drive by sliding the mechanism.
- Carefully insert the USB-C connector of the flash drive into the device's USB Type-C port. Ensure it is fully seated.
- Your device should automatically detect the flash drive. On most operating systems, a notification will appear, or the drive will be accessible through your file explorer (e.g., 'This PC' on Windows, 'Finder' on macOS, or a file manager app on Android).
For smartphones and tablets, ensure your device supports USB On-The-Go (OTG) for proper functionality.
Operating the Device
File Transfer:
- Once the flash drive is connected and recognized by your device, open your device's file manager or explorer.
- Navigate to the files you wish to transfer (e.g., documents, photos, videos).
- Select the desired files or folders.
- Copy or cut the selected items.
- Navigate to the SanDisk Ultra USB Type-C Flash Drive in your file manager.
- Paste the copied or cut items into the desired location on the flash drive.
Using SanDisk Software:
- SanDisk SecureAccess Software: This software allows you to create a password-protected folder on your drive to secure sensitive files. Download and install the software from the official SanDisk website. Follow the on-screen instructions to set up your vault.
- SanDisk Memory Zone App (for Android): Download and install the SanDisk Memory Zone app from the Google Play Store. This app helps you organize, manage, and back up files on your Android smartphone or tablet, including those on your SanDisk flash drive.

Maintenance
Proper care of your SanDisk Ultra USB Type-C Flash Drive will ensure its longevity and reliable performance.
- Safe Ejection: Always safely eject the flash drive from your device before physically removing it. This prevents data corruption and ensures all write operations are completed. On Windows, right-click the drive icon in 'This PC' and select 'Eject'. On macOS, drag the drive icon to the Trash or click the Eject button next to the drive in Finder. On Android, use the 'Unmount' or 'Eject' option in your device's storage settings.
- Physical Protection: Keep the drive clean and free from dust and debris. Use the retractable connector feature to protect the USB-C plug when not in use. Avoid exposing the drive to extreme temperatures, direct sunlight, or high humidity.
- Avoid Physical Impact: Do not drop the drive or subject it to strong impacts, as this can damage internal components.
- Data Backup: While the drive is reliable, it is always recommended to keep important data backed up on multiple storage devices or cloud services to prevent data loss.
Troubleshooting
If you encounter issues with your SanDisk Ultra USB Type-C Flash Drive, try the following common troubleshooting steps:
- Drive Not Recognized:
- Ensure the drive is fully inserted into the USB-C port.
- Try a different USB-C port on your device.
- Test the drive on another computer or compatible device to rule out a device-specific issue.
- Restart your computer or device.
- Check your device's Device Manager (Windows) or System Information (macOS) to see if the drive is listed, even if it's not assigned a drive letter.
- Slow Transfer Speeds:
- Ensure you are using a USB 3.1 Gen 1 or USB 3.0 compatible port. Older USB 2.0 ports will result in significantly slower speeds.
- Transferring many small files can be slower than transferring a few large files.
- Close other applications that might be using system resources or accessing the drive.
- Ensure your device's drivers are up to date.
- Cannot Write Files to Drive (Read-Only):
- The drive might be formatted with a file system that is read-only on your operating system (e.g., NTFS on macOS without third-party software).
- The drive might be corrupted. Try formatting the drive (this will erase all data).
- Check if the drive has reached its storage capacity.
- Data Corruption:
- Always safely eject the drive before removal.
- Run a disk check utility (e.g., 'Error checking' on Windows, 'Disk Utility' on macOS) to scan and repair potential errors.
- If data is lost, consider using the included RescuePRO Deluxe software.
If these steps do not resolve your issue, please refer to the SanDisk support website for further assistance.
