5. Troubleshooting
If you encounter issues with your SanDisk Ultra Dual Drive Luxe, consider the following common troubleshooting steps:
- Drive Not Detected: Ensure the drive is fully inserted into the USB port. Try a different USB port or a different device to rule out port issues. For mobile devices, ensure OTG functionality is enabled if required by your device.
- Slow Transfer Speeds: While the drive supports up to 400MB/s read speeds, actual performance can vary based on the host device, file size, and other factors. Ensure you are using a USB 3.0/3.1/3.2 compatible port for optimal performance.
- Heating During Use: It is normal for the drive, especially its metal casing, to become warm during extended use or large file transfers. This is due to the heat dissipation properties of the metal and typically does not indicate a malfunction.
- File Corruption: Always safely eject the drive from your computer or mobile device before removing it to prevent data corruption.
