Today, the soft media editor has compiled a total of 5 solutions from the network, both simple and slightly cumbersome.

It is not unreasonable to grow up and help others.

The first method:

Often when we take out the files or data of the U disk, we use the "copy" and "paste" methods, and if we copy The file on the U disk, this file will always be placed in the system's clipboard, in a standby state. And if we want to delete the USB flash drive in this case, the above prompt that cannot stop the USB flash drive will appear.

The fifth method:

This method is the simplest, but the most time-consuming, that is, restart your computer.

Small door: At present, some U disk technology is in place, and some U disk can be plugged and unplugged. But no matter how good the U disk, there is a time when it can't be directly plugged and unplugged. That is to look carefully at the small red light of your U disk. When the small light does not stop flashing, it means that it is constantly reading and writing data. At this time, you must not pull it, otherwise it will damage the data, but the U disk will be scrapped.
