Why does the dash cam suddenly fail to detect the TF card?
2 Answers
The reasons why the dash cam suddenly fails to detect the TF card are as follows: 1. Memory card failure: The memory card is damaged and cannot store data, causing the recorder to fail to recognize it during detection and thus unable to continue working. Solution: Replace the memory card for testing. 2. Card reader or peripheral component damage: Oxidation of the 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; components in the peripheral circuit of the card reader are damaged, causing power supply or signal transmission interruption, etc. Solution: Clean the inside of the card reader with a toothpick or replace the card reader.
I've encountered situations where the dash cam couldn't detect the TF card, which seems quite common. One summer when I parked my car, the dash cam alerted me that the card had failed, and several attempts didn't help. Later, I asked a knowledgeable friend and summarized several possible reasons: First, the TF card itself might be damaged, such as long-term wear leading to poor internal contact; second, the card slot contacts in the dash cam might be dirty or loose, with dust affecting reading; third, the file system on the card might be corrupted and require formatting to recover; fourth, there might be a software issue with the dash cam, such as outdated firmware being incompatible with new cards; fifth, the card might be sensitive to external conditions, where high temperatures or vibrations could temporarily cause errors. That time, I pulled out the card, cleaned the slot, and formatted it using a computer, which solved the problem. I recommend not leaving the device exposed to direct sunlight for too long when parked and using branded cards for better durability. If you encounter similar issues, don't panic—checking things yourself can save a lot of money.
