What could be the reason when a car USB flash drive shows no response after being plugged in?

When a car USB flash drive shows no response after being plugged in, it could be due to the following reasons: Loose USB connection: Since the USB flash drive is often left plugged into the car's USB port for extended periods, the vibrations and shaking of the vehicle during driving can easily cause the connection to become loose. Once loose, the car's USB port may suddenly stop reading the flash drive. Damaged USB flash drive: The likelihood of a USB flash drive being damaged is relatively low, but given the less-than-ideal environment inside a car (especially during the high temperatures of summer), the possibility cannot be ruled out. Damaged USB port: The chance of a USB port being damaged is believed to be even lower than that of a USB flash drive being damaged. However, if none of the above issues are present, the possibility of a damaged USB port should also be considered.
I encountered the issue of a car USB drive not responding last year, and it was really frustrating at the time. Upon checking, I found out the USB drive itself had failed—it wouldn't even boot up when tested on a computer. This kind of problem is quite common; USB drives can easily get damaged after prolonged use or if dropped, and the solution is simply to replace it with a new one. Additionally, USB drive format compatibility is a big deal. For example, my car's system only recognizes FAT32 format—if it's formatted as NTFS, it definitely won't be readable. Dirty USB ports can also cause issues; try cleaning the port with a cotton swab dipped in alcohol and then restart the car's infotainment system. Sometimes, a simple reboot can fix software glitches. Also, avoid using oversized USB drives—some car systems may not support drives larger than 64GB, so check the specifications in the manual. It's a good habit to carry a spare USB drive while driving and test it beforehand to avoid mid-journey troubles. I now regularly back up my music files to my computer to minimize headaches.
