The SD card of the on board dash cam shows the reason for the read and write failure

USB flash drive digital card mobile phone card:

First of all, you need to confirm whether the SD card is good, and you can try it by replacing it.

1.Connect the card reader to the computer and see if the drive letter capacity is good.

2.If it doesn't work, you can try another computer or card reader. If it still doesn't work, it may be that there is a problem with the card and it has nothing to do with the machine.

3.The machine changes to another good card, try to see if it still shows this problem. If it is still, it proves that there is no problem with the card, but the machine settings or somewhere are damaged, need to be repaired or whatever.

The card cannot be repaired, if there is data, it can be recovered. USB flash drive digital card mobile phone card: "prompt formatting", "unable to open normally","The device is not working properly"：

This situation is that there is no secure deletion during use, and after directly unplugging it, it will become "Prompt formatting" "Unable to open normally" "Device is not normal" "0 bytes" cannot be opened.

There are two types of situations.

1. Due to the sudden pull out of the U disk digital card mobile phone card, the loss of the FAT damage prompts insertion into the disk or formatting. In this case, it would be good to format the ** software on the Internet, such as diskgenius. If it doesn't work, try it with mass production tools.

2. Hard fault: due to sudden unplugging, the voltage instability may cause damage to the sperm element or burn the chip. Caused by the failure of the U disk itself such as crystal oscillator virtual welding.

In this case, I recommend that you find a professional data recovery company, or a USB flash drive repair company to try to repair the general recovery ** in about 200-300. Don't try to unpack the shell yourself, if there is a hard failure, you need to polish the memory card to extract the essence to recover, then 3000 up, don't try it yourself to avoid aggravating the failure. If you don't have important data, I'd suggest you switch it out!
