6. Troubleshooting
If you encounter issues with your Lexar ES3 Portable SSD, consider the following general troubleshooting steps:
- Device Not Recognized:
- Ensure the cable is securely connected to both the SSD and your device.
- Try a different USB port on your computer.
- Test with a different USB cable if available.
- Restart your computer or device.
- For Mac users, check Disk Utility to see if the drive is detected but unmounted or unformatted.
- Slow Transfer Speeds:
- Ensure you are using a USB 3.0/3.1/3.2 compatible port on your device for optimal speeds. Older USB 2.0 ports will result in slower performance.
- Close any unnecessary applications running in the background that might be consuming system resources.
- Verify that your device's drivers are up to date.
- Drive Gets Warm:
- It is normal for the drive to become warm during high-speed data transfers due to its metal casing acting as a heatsink. If it becomes excessively hot or performance degrades, ensure it has adequate airflow and is not covered.
