The storage chip of the USB flash drive is a flash memory chip, and its lifespan is closely related to its service life. If you use the USB flash drive for a long time and frequently, or copy files to the USB flash drive frequently, the flash memory chip may be damaged, resulting in data loss. In addition, incorrectly inserting or removing the USB flash drive may damage the memory chip and cause file loss.

3. File damage caused by virus infection: The U disk is susceptible to virus infection when it is inserted into an unsafe computer. Once the USB flash drive is infected, the virus will quickly replicate and spread in the USB flash drive, affecting the file system and file structure in the USB flash drive, resulting in file damage or loss. In this case, you should use anti-virus software to remove the virus as soon as possible to protect the files in the USB flash drive from further damage.

1. Back up important files regularly: Back up important files to the cloud or another USB flash drive to prevent file loss.

2. Avoid creating too many files on the USB flash drive: Too many files may cause insufficient storage space on the USB flash drive, resulting in file loss or damage.

3. Avoid inserting the USB flash drive into an unsafe computer: An unsafe computer may be infected with viruses or malware, thereby destroying the files in the USB flash drive.

4. Use genuine anti-virus software: Using genuine anti-virus software can promptly detect and remove viruses and other malware, and protect the files in the USB drive from damage.

5. Pay attention to physical protection: Protect the USB flash drive itself to prevent it from physical damage such as being dropped or soaked in water.

In short, for the problem of files in the USB flash drive suddenly disappearing, you can try to find the cause and solve the problem from the above aspects. At the same time, taking preventive measures can effectively avoid similar problems from happening.
