This is actually the reason why the USB flash drive can't pop up.,I hope you don't mind if I copy a piece of text elsewhere.。
When you delete USB flash drive safely, you often encounter a message that says, "The 'Universal Volume' device cannot be stopped, please stop the device later." In this case, can you forcibly unplug the USB flash drive? Of course not!
At this time, if you forcibly remove it, it is easy to damage the USB port of the computer or your USB flash drive.
The first method (which is also the most common method I recommend to everyone): Often when we take out the files or data from the USB flash drive, we use the "copy" and "paste" methods, and if the file on the USB flash drive is copied, the file will always be placed in the system's clipboard and in a standby state. And if we want to delete the USB flash drive in this case, the above prompt that the USB flash drive cannot be stopped will appear.
The corresponding solution is: empty your clipboard, or copy a file on your hard disk and then paste it, at this time you delete the USB flash drive prompt to see if it is successfully deleted?
Second method: If you don't think the above method is working, open it"Task Manager"window, click"process"tags, find""process, and then click"End the process", a Task Manager warning will pop up, asking you whether to close the process or not, click on it"Yes", i.e. closed""processThen delete the USB flash drive and you can delete it normally.
Note when using this method: if there is more than one""process, you need to put more than one""Processes are all shut down.
The third method: This method is also with the help of Task Manager, click"process", search""process and end it. At this time, you will find that your desktop is gone, please do not panic, continue to the following operations, click "File" - "New Task" - enter OK in the task manager.
Then delete the USB flash drive, and you will find that it is safe to delete.
The fourth method: This method is the easiest, but most time-consuming, and that is, restart your computer. Beg!!
