What are the reasons why the dash cam cannot recognize the memory card?

[Rhett]

The reasons why the dash cam cannot recognize the memory card: the memory card is damaged or the card slot for installing the memory card on the dash cam is damaged. The following are the related explanations: Memory card damage: Since the dash cam needs to continuously read and write data, this causes significant wear and tear on the memory card. Moreover, the dash cam is often exposed to the sun for long periods, and the memory card operates in high-temperature environments, which severely tests its quality. When using a low-quality memory card, it is easily burned out and unable to store data, causing the dash cam to fail to recognize the memory card during detection and thus unable to continue working. In this case, you can replace the memory card for testing. Damage to the memory card slot: The internal metal contacts of the card reader oxidize, leading to poor contact with the memory card; the card reader itself is damaged, making it unable to read the memory card; or components in the peripheral circuit of the card reader are damaged, causing power supply or signal transmission interruptions, etc. In this case, it is recommended to clean the inside of the card reader with a toothpick or replace the card reader. If this does not work, further inspection of the surrounding circuits is needed.
