6. Troubleshooting
If you encounter issues with your Lexar ES3 Portable SSD, please refer to the following common problems and solutions:
- Drive Not Detected:
- Ensure the USB cable is securely connected to both the SSD and your device.
- Try connecting to a different USB port on your device.

- Verify that your operating system and drivers are up to date.
- Avoid transferring many small files simultaneously, as this can reduce overall transfer rates.
- Close other applications that might be using system resources or the USB bus.
- Data Corruption or Errors:
- Always safely eject the drive before disconnecting it.
- Run a disk check utility (e.g., CHKDSK on Windows, Disk Utility on macOS) to scan for and repair errors.
