What to do if 'Low Speed Card!' warning appears frequently on Zoom Q2n-4K DVR?
If you frequently see a 'Low Speed Card!' warning or stopping recording takes a long time on your Zoom DVR, it might be due to the microSD card becoming worn out from repeated writing and erasing, which decreases its speed. Try formatting the card. If formatting doesn't help, consider replacing the microSD card.
