Why can't the dash cam detect the memory card?
4 Answers
The dash cam's inability to detect the memory card can be caused by the following two situations. Below are the reasons and corresponding solutions: 1. The memory card is faulty; the memory card is damaged and cannot store data, causing the dash cam to fail to recognize it during detection and preventing it from continuing to work. Solution: Replace the memory card for testing. 2. The card reader or peripheral components are faulty. The metal contacts inside the card reader are oxidized, 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 card reader's peripheral circuit are damaged, causing power supply or signal transmission interruptions. Solution: Clean the inside of the card reader with a toothpick or replace the card reader. If this doesn't work, further inspection of the surrounding circuits is necessary.
I've been driving for almost twenty years and have encountered several instances where the dashcam couldn't recognize the memory card. At first, I was quite anxious, but later I realized that many cases were due to the memory card reaching its lifespan—constant daily read/write operations can cause cheaper, no-name cards to burn out easily. Another common issue is dust accumulation or looseness in the card slot. The constant jostling in the car can cause an improperly inserted card to become loose. I suggest you first remove the card, clean the contacts, and try formatting it on a computer using FAT32 instead of exFAT, as many dashcams only recognize the former. Also, avoid using overly large capacity cards—16GB is usually sufficient, as larger capacities might overwhelm the dashcam. If a new card still doesn’t work, the issue might be outdated dashcam firmware; updating it should help. No need to rush to a repair shop—save some money. Always keep a spare card in your car. It’s dangerous to miss recording critical moments—I once lost crucial accident evidence due to a faulty card, a lesson I won’t forget.
I'm the type who loves tinkering with electronic devices, and my dashcam has had this issue before. Most of the time, it's because the memory card wasn't inserted firmly enough, or the contacts were dusty—a simple wipe might solve it. Don't underestimate these small issues; card failures are quite common. I've tested several cards, and the cheaper ones have a shorter lifespan and are prone to failure under high temperatures, so it's best to go for a branded one like SanDisk. Formatting issues shouldn't be ignored either—dashcams typically support FAT32. If the card is in another format, it won't be readable. Just right-click on your computer and format it correctly. As for capacity, cards larger than 64GB might not be compatible, so avoid using oversized cards. Key maintenance tips: never remove the card while the dashcam is on, as this can cause malfunctions. If all else fails, try a new card—they're not expensive anyway. If there's still no response, it might be a firmware bug in the dashcam. Just download the update tool from the official website, and it's an easy fix. Regularly check your dashcam's status—safety first.
The dash cam cannot read the memory card, mainly due to three key reasons: First, the memory card is damaged or excessively worn out, like the one I replaced, which was found to have oxidized contacts and became unusable; Second, poor contact due to dust or looseness in the card slot, requiring cleaning or pressing firmly; Third, incompatible format or capacity, as the dash cam only recognizes FAT32 format—if the new card is NTFS or too large, like 128GB, issues may arise. For solutions, first try a new card to see if it works; if not, clean the contacts; then format the card to the correct format. Compatibility is also crucial—avoid using old cards or cheap brands.
