6. Troubleshooting
6.1 SSD Not Recognized
- Check Cable Connection: Ensure the USB cable is securely connected to both the SSD and your device. Try a different USB port or cable.
- Verify Compatibility: Confirm your device's USB port type (USB-C, USB-A) and ensure you are using the correct cable or adapter.
- Check Device Manager (Windows) / Disk Utility (macOS): See if the drive is detected but not assigned a drive letter or needs initialization/formatting.
- Restart Device: Sometimes a simple restart can resolve connectivity issues.
6.2 Slow Data Transfer Speeds
- USB Port Type: Ensure you are connected to a USB 3.2 Gen 2x2 compatible port on your host device for maximum speeds. Older USB ports (e.g., USB 2.0, USB 3.0/3.1 Gen 1) will result in lower speeds.
- Cable Quality: Use the original Samsung cables provided, as third-party cables may not support the full speed capabilities.
- System Load: High CPU usage or other background processes on your computer can affect transfer speeds.
- File Type: Transferring many small files is generally slower than transferring a few large files.
- Thermal Throttling: While the T9 has Dynamic Thermal Guard, extreme environmental conditions or prolonged heavy use might still impact performance. Ensure adequate airflow around the drive.
6.3 Magician Software Not Detecting SSD
- Reinstall Software: Uninstall and reinstall the latest version of Samsung Magician Software.
- Update Drivers: Ensure your system's USB controller drivers are up to date.
- Check BIOS/UEFI Settings: Ensure USB ports are enabled and configured correctly.
