U disk virus is also one of the common reasons why U disk cannot be formatted. The virus will modify the boot sector of the USB flash drive, hide the files in the USB flash drive, etc., and interfere with the formatting operation.

Solution: First use professional anti-virus software such as Kaspersky and Norton to fully scan and kill the USB flash drive. Then use DiskGenius's "Clear by Sector" function to perform low-level formatting on the USB flash drive to completely remove the virus. The specific steps are as follows:

1. Run DiskGenius, select the problem U disk, and click "Tools" - "Clear by Sector".

2. Select "Completely fill zero data" and click "OK" to start clearing.

3. After the clearing is completed, use the formatting tool that comes with Windows to format the USB flash drive.

3. Do not open executable files in USB flash drives on public computers to prevent virus infection.

4. The USB flash drive is placed in a dry and cool place to avoid exposure to sunlight, high temperature, humidity and other unfavorable environments.

5. When purchasing a USB flash drive, choose a well-known brand and carefully identify the authenticity to avoid purchasing low-quality products with a high failure rate.
