Troubleshooting
- Drive Not Recognized:
- Ensure the drive is fully inserted into the USB port.
- Try a different USB port on your device.
- Try connecting to a different computer or device to rule out port issues.
- Check your operating system's Disk Management (Windows) or Disk Utility (macOS) to see if the drive is detected but uninitialized or unformatted.
- Slow Transfer Speeds:
- Ensure you are connected to a USB 3.2 Gen 2 compatible port for maximum performance. Older USB 2.0 or 3.0 ports will result in lower speeds.
- Verify that your computer's drivers for USB ports are up to date.
- Large numbers of small files transfer slower than fewer large files.
- Other background processes on your computer can affect transfer speeds.
- Drive Gets Warm During Use:
It is normal for the drive to become warm during extended high-speed data transfers due to the nature of SSD technology and the metal casing acting as a heat sink. This does not indicate a malfunction.
