When the SD card cannot be read, the first thing to check is whether the connection between the SD card and the device is normal. Sometimes, due to improper insertion or problems with the device interface, the SD card may not be recognized properly. At this point, we can try the following:
1. Take the SD card out of the device and check whether the metal contact piece of the SD card has dirt or oxidation. If you have one, you can gently wipe it with an eraser and plug it back in.
2. Check whether the device interface is clean and whether there are foreign objects. If necessary, you can use a cotton swab dipped in a small amount of alcohol to gently wipe the connector, and then insert the SD card after the alcohol has evaporated.
3. Try inserting the SD card into another device to rule out the possibility of device interface failure. If it is also unreadable on other devices, then it could be an issue with the SD card itself.
2. Use the repair tools that come with the system.
For Windows system users, when the SD card is unreadable, you can try to use the repair tool that comes with the system to fix it. The specific steps are as follows:
