How to Fix Dash Cam Slow Card Error

Way 1. Change a Card

When you encounter the SD card slow error in dash camera, the first thing you need to do is determine whether the problem is with the SD card or the dash cam itself. To do this, you can replace the SD card with a working one and see if the error message still appears. If the error persists, the problem may be with the dash cam rather than the SD card.

Way 2. Update the Dashcam Firmware

If your dash cam’s firmware is not up to date, it may have some bugs or cause compatibility issues with the SD card. In this case, you can go to the manufacturer’s website to check for any firmware updates for your model. If there is an available update, download and install it.

Way 3. Decrease Recording Time to 1-Min Loop

If your dashcam has a loop recording function, setting a longer recording interval may cause the SD card to display a slow card error or other errors. In this case, you can change the loop recording interval to a shorter time, such as 1 minute, to reduce the amount of data written at one time.
