If you are trying to connect your mobile or external device to your Windows 10 computer but suddenly encountered an error saying, “A device attached to the system is not functioning”, read on as this post will guide you on how you can resolve this error using a couple of potential fixes. In this case, it is possible that the connected device is not working for some reason and this error pops up when you connect your device or when you try to move or copy files from your computer to your external device and vice versa. As you can see, the error message is pretty straightforward, and it mostly occurs when you connect plug and play devices such as USB drives, printers, external storage devices, and many more. And when you open the Device Manager to check the device, you will most likely see a yellow exclamation mark on the device which indicates that the device is currently having problems. To fix this problem, there are several options you can check out. You need to check the status of the device or check the compatibility between the external device and the drive types. You also have to make sure that the device is connected properly or check if the device has been formatted properly. For more details, follow the given suggestions below.

Option 1 – Try to check the status of the device

The first thing you can do to get rid of the error is to check the status of the external device, especially if it’s a plug-and-play device. So when your computer boots, check if it is able to detect the device or not.

Option 2 – Try to check the compatibility between the external devices and drivers

As you know, when you connect an external device to your computer, Windows installs drivers to communicate with the device, the same way as any hardware you connect to the motherboard and if the driver ends up getting corrupted or is incompatible, then you need to update the device driver. To do that, follow the steps below.

• First, click the Start button and type “device manager”.

The first thing you have to do before you further troubleshoot the problem is to check the hardware connections of your computer and see if there are damaged ones, just like with USB ports, it would also affect the overall connectivity of the device with the computer. So if you notice some irregularities in the connecting cable physically, you might have to buy another one and replace it and then see if it fixes the problem or not.

Option 4 – Check if the device is formatted properly

You might also want to check if the external device is properly formatted especially if you’ve recently formatted it. If a device wasn’t formatted properly, then it’s no wonder why you’re getting the “A device attached to the system is not functioning” error. To fix this, you need to use Disk Management. From there, you can find the devices connected but are not visible. If you are using an admin account, then to fix this error, you have the option to format the drive or create new partitions using the interface. Once you do this, it should resolve the problem.

Option 5 – Try to run System File Checker or SFC scan

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.
• Once done, restart your computer.

Option 6 – Restart your computer in a Clean Boot State

If a third party program like antivirus is the one that’s causing the problem, you can try to put your computer in a Clean Boot State to isolate the issue by following these steps:

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to connect your device or copy the files to your external device again and check if the error is now gone.

Many Linux users if not all of them can run their distros from a USB drive but did you know you can run Windows 10 from a USB drive as well? Microsoft has introduced all the way back to Windows 8 one feature called Windows To Go and it kept it in Windows 8.1 and in Windows 10 as well. This feature is intended as a convenient way for workers to carry their corporate environments with them, but having your own copy of Windows on a thumb drive could be handy for backup purposes, too, or if you frequently use public machines that lack your preferences/applications or that have a restricted OS.

What you will need?

In order to actually make Windows 10 run from a USB drive you will need the following things:

1. USB drive with a minimum size of 20GB
2. Working computer with Windows 10 running on it
3. Rufus or another ISO to UBS tool, get Rufus here: https://rufus.ie/en_US/
4. Windows 10 ISO file

Making Windows 10 UBS drive

Install Rufus on your Windows 10 and run it. Stick USB in PC and open Rufus. On the screen that follows choose your Windows 10 ISO image and under Image options choose Windows To Go. Click on ready and you are finished, that’s it. After Rufus finishes you have now fully working Windows 10 bootable drive which you can use on another PC for whatever reason.
