When we use a U disk, sometimes the U disk pops up and displays "The device is in use". How should we deal with this? In actual operation, this may be caused by system processes, file operations, etc. PHP editor Xiaoxin will introduce you to several solutions. First, you can try to close all programs related to the U disk, and then safely pull out the U disk; secondly, you can end the process occupying the U disk through the task manager, and then try to eject the U disk; finally, you can restart the computer and try to eject the U disk again. plate. Through these methods, I believe you can successfully solve the problem of "This device is in use" when the USB flash drive is ejected.
1. Cause of the problem
The reason why the prompt "This device is in use" when ejecting the USB flash drive is very simple. Generally, there are the following two points:
①Some programs on the computer are using certain files in the USB flash drive.
② Certain software or programs are accessing the USB flash drive in the background of the computer, such as Windows security software, anti-virus software, etc.
2. Solution
Solution 1. Close all running programs and temporarily disable Windows security software
When we close all running programs, generally there will be no situation where some programs are using the U disk device file, so the U disk can be ejected successfully. Specific steps are as follows:
Step 1: Close all open program windows in the taskbar, then click the upward arrow on the right side of the taskbar to see if there are any programs that may still access the USB flash drive, right-click the program icon and select [Exit].
Step 2: Since there may be programs running in the background accessing the USB flash drive, you can right-click the taskbar at the bottom of the desktop and select [Task Manager].
Step 3: In the task manager, we can view all programs that are running or running in the background, select the program that you know or open manually (for example, you have just accessed the files in the USB flash drive through this program), and then click [End] Task] to try ejecting the USB flash drive again. Please note that if some program names look unfamiliar, please do not end the task to avoid losing the necessary processes to keep the Windows system running. If you have closed all running programs that you know but still cannot successfully eject the USB flash drive, you can temporarily disable Windows security software or third-party anti-virus software, and then safely eject the USB flash drive.
Solution 2. Find and close the program occupying the U disk file
Method 1: Closing all running programs is not suitable for all users, especially when there are other uninterruptible tasks to be done. Then you can try to find the programs currently occupying or accessing the USB flash drive in the Resource Monitor in the Task Manager. , and then close the program. Methods as below:
Step 1: Right-click the taskbar at the bottom of the desktop and select [Task Manager].
Step 2: Switch to the [Performance] tab bar and select [Open Resource Monitor].
Step 3: Enter the drive letter of the U disk in the input box to the right of "Associated Handle" in the [CPU] interface. For example, the U disk drive number is [E:], then please enter [E:], and you can view it later. Go to the program currently associated with [E:] (2345PicViewer.exe as shown below), right-click the program and select [End Process], and then the U disk can be successfully ejected. Do not end other processes that you do not recognize or are familiar with, so as not to affect the normal operation of Windows 10.
Solution 3. Eject the U disk in Disk Management
Disk management can help us view all connected storage devices in Windows computers, including USB flash drives. In addition, you can use Disk Management to format, delete volumes, extend volumes, or eject disks on your computer. It should be noted that this method will not close the program that is accessing the USB flash drive file, so please make sure that the USB flash drive file has been properly saved before proceeding. Specific steps are as follows:
Step 1: Right-click the Start button and select [Disk Management].
Step 2: Find the target U disk, which is disk 3 in the picture below, right-click the location where disk 3 is displayed on the left, and select [Eject].
Step 3: Afterwards, the U disk will become "no media" in the disk management.
Step 4: And the U disk cannot be opened in the file explorer. Double-clicking the U disk will prompt [Please insert the disk into "test (E:)"]. The USB drive can now be removed.
If the U disk cannot be used normally when connected again and "Offline" is displayed in the disk management, please right-click the location of "Offline" and select [Online].
