Why can't the dash cam recognize the memory card?
2 Answers
The dash cam's inability to recognize the memory card may be due to a damaged memory card or a faulty card reader/peripheral components. Here are some possible reasons regarding the dash cam's memory card recognition issue: 1. Damaged memory card: A corrupted memory card cannot store data, causing the dash cam to fail in detecting the card during operation. Solution: Replace the memory card for testing. 2. Faulty card reader or peripheral components: Oxidation of metal contacts inside the card reader leads to poor contact with the memory card; The card reader itself is damaged, resulting in failure to read the memory card; Damaged components in the card reader's peripheral circuit cause power supply or signal transmission interruption, etc.
A few days ago, my car dashcam also had this issue—it couldn’t read the memory card at all. There are quite a few possible reasons. The most common one is that the card itself is damaged, possibly from too many rewrites reaching its lifespan limit. Or the card might not be formatted correctly—it needs to be in FAT32 format, otherwise the dashcam won’t recognize it. Poor contact is another pitfall; dust or oxidation in the card slot can cause unstable connections—try gently cleaning it. The type of card is also crucial: high-speed cards like Class 10 or above are suitable for HD recording, while ordinary low-speed cards may cause lag or failure. Don’t greedily opt for excessive capacity—if the manual says it supports 64GB, don’t force a 128GB card. Here’s how I fixed it: formatted the card on a computer, cleaned the card slot, and updated the dashcam firmware to the latest version from the official website. When choosing a card, check the compatibility list to avoid wasting money on incompatible ones, and regularly back up videos to prevent accidental loss.
