When ejecting a USB from your computer, you may receive this error “Windows is unbale to stop the device…”. Once getting this error, please do not be panic. This article shows you how to restore the lost data from the USB massage storage device, with MiniTool Partition Wizard, and how to fix it with 5 methods.

Windows Is Unable to Stop the Device

Like most computer users, you prefer using a USB mass storage device to transfer data with ease between computers. Furthermore, with the capacity of that device increasing (like 1TB USB), more and more computer users use it to save data backup.

When we finish transferring data between computers with USB, we often unplug the device by disabling it in the “Safely remove a hardware and eject media” menu in case of data loss.

However, sometimes we may fail to safely remove the device as a message says “Window is unable to stop the device…”, informing it is still being in use.

This error can be blamed on certain files on the USB that might not be closed properly or may be running on your computer. Some other third-party programs might also be using the data included in your USB device.

In the following, we will not only show you how to fix this error but also guide you on how to recover the lost data from USB if you unplug this device without applying the “Safely remove a hardware and eject media” option and then its partition becomes RAW.

To check the Event Log, please do the following steps:

Step 1: Press Windows + R simultaneously to get Run box. When the box pops up, please type eventvwr and press OK.

open Event Viewer

Step 5: Now open the log which is left behind. Under the General tab, you will see the application that was leading to “Windows is unable to stop the device”. Then you should go to Task Manager and find this application to end it.

Windows Is Unable to Stop the Device FAQ

What happens if you don’t eject USB properly?

Data loss or data corruption will happen whether your system is writing data to your USB or not.

Most operating systems use write caching to get better performance out of your computer. If you interrupt the writing process abruptly, data corruption may happen. Certainly, do not yank out the drive directly even if the writing process has finished.

How do I safely remove USB from Windows 10?

To safely remove USB from Windows 10, follow the steps below.

  1. Double-click This PC on your computer screen.
  2. Find your USB on the new window and then right-click it. Select Eject from the right-click menu.
  3. Wait for the Safe to Remove Hardware message appear. Once it appears, it means that the device is ready to be removed. Gently remove the USB from the computer.
Where is the Eject button in Windows 10?

I guess that the Eject button in the question refers to the Safely Remove Hardware icon or the Eject option.

This Safely Remove Hardware icon is on the taskbar. If you don’t see it, please select the Show hidden icons.

If you still cannot find the icon, follow the steps below to get it back on taskbar.

  • Right-click the taskbar and then select Taskbar settings.
  • Choose Select which icons appear on the taskbar under the Notification area.
  • Scroll to Windows Explorer: Safely Remove Hardware and Eject Media and turn it on.

You can find the Eject option by following the steps I mentioned in the second question.

Is remove device the same as eject?

The answer is NO.

Eject: This option removes the media from the device but does not remove the device itself. For example, on Windows computer, even if you have clicked Eject, you still can see the drive letter of the removable device on File Explorer but you cannot open this device.

Safely Remove: This option flushes any pending writes from the writing cache and removes the entire device.
