If you are a Windows user, sometimes you cannot safely remove your removable drive even when you haven’t opened any files or programs from the drive. But still your Windows cannot safely remove it. It always says “Problem Ejecting USB Mass Storage” — it is a very annoying message, isn’t it?
Windows cannot safely remove your removable drive because there is at least one process running in the background and the handle is still hooked to your removable drive. The best and free tool to release this process that blocks you from safely removing your removable drive is Unlocker.
With Unlocker you can see what process and handle is still hooked to your removable drive. See the screenshot below:
Besides being free, it is also very easy to use. Just right-click on your removable drive and click Unlock. You will see a screen like the screenshot above. Just press Unlock All. Now you can safely remove your removable drive without the annoying message from Windows. It’s that easy.
