Fix it now
- Copy any clips you want to keep: formatting deletes everything.
- Format the card in the dash cam's menu, not on a computer, so the camera sets it up the way it expects.
- Check for a firmware update for the camera.
- If the error returns within days, replace the card.
Why cards fail in dash cams
Loop recording rewrites the card constantly, and cars get very hot and very cold. Ordinary cards are not built for that. High-endurance cards are rated for continuous recording and last much longer.
Which card to buy
Check your camera's maximum card size and speed class in its manual, then choose a high-endurance card within that limit. See our page on dash cam memory card sizes for how many hours each size holds.

Frequently asked questions
How often should I format my dash cam card?
Nextbase recommends every 2 to 3 weeks for most users. Other makers suggest at least monthly.
Can I format the card on my computer?
It is better to format it in the camera, which sets up the card for its own recording.
Why does the error appear when the card is not full?
Usually corrupted files or a worn card, not a lack of space. Format it, and replace it if the error comes back.
