Error 0x800701B1 on Windows 10 [Solved] - Best IT Guide (2023)

Error 0x800701B1 on Windows 10 [Solved] - Best IT Guide (1)

Some Windows 10 users regularly encounter error code 0x800701b1 (A nonexistent device was specified) when trying to copy, paste or replace files using File Explorer. This error code is also reported in cases where users try to install Windows 10 on a hard drive connected via a USB port.

Copying and pasting files or folders from one hard drive to another is usually an easy and error-free process in Windows 10. However, several Windows 10 users complain about the 0x800701B1 error on their computer when they perform file/folder transfer regardless of the size of the data being copied.

What causes error code 0x800701B1 on Windows 10

As it turns out, there are several different causes that can lead to this particular error code. Here is a short list of potential culprits that could be responsible for the appearance of the 0x800701B1 (a non-existent device has been indicated):

  • USB 2.0 port is poor – Depending on what type of HDD/SSD drive is experiencing this issue, you may need to connect it to a USB 3.0 port to ensure you get the required transfer speeds and performance.
  • Inconsistent/Incompatible Driver – According to some concerned users, if you are using a generic driver for the external drive that is throwing this error code, you can expect this error code. In this case, you might be able to fix the problem by reinstalling the dedicated driver.
  • Insufficient PSU Power – If you have an average PSU and many attached peripherals that are currently consuming power, consider that your power source may not be sufficient to operate each device. In this case, you can fix the problem by either upgrading your power supply or disconnecting some non-essential peripherals.

how to fix it

When it comes to fixing the 0x800701b1 error, there are numerous things to keep in mind and consider. Before we get into anything complex, below are some simple tips to try.

The first thing I suggest is that you limit the size of the files you want to transfer to and from your external drive. Of course, whether you can implement this idea depends heavily on when the error occurs. But assuming it occurs while using an external drive. You should limit your file size to 10 GB or less.

Transferring large files puts a heavy load on your system, especially if it is relatively old. So you should definitely try to break up your file transfers into small, more manageable chunks.

If the above solution fails to fix the problem, I suggest you try the many solutions listed below.

Solution 1: Connect your external device to a different USB port

(Video) How To Fix Error 0x800701b1 - A Device Which Does Not Exist Was Specified

Error 0x800701B1 can appear due to insufficient performance or insufficient transmission speed. USB 3.0 typically has a higher data transfer rate and offers more efficient power management.

If your computer has multiple USB ports, please try connecting your external hard drive or USB flash drive to your computer through a different USB port. If your external drive comes with USB 3.0 interface, you'd better connect it to USB 3.0 port instead of USB 2.0 port.

Solution 2: Remove other peripherals

If this error is caused by insufficient power, try disconnecting all other devices connected to your computer. Just unplug them all.

If you're using a laptop, unplug absolutely all your peripherals and leave only the external hard drive plugged in. You can use your trackpad to control your device. Check if the error is gone.

Solution 3: Update or reinstall the hard drive driver

An outdated or corrupted hard drive driver could also lead to error code 0x800701B1. To solve the problem in this case, you can try updating or reinstalling the driver software. Here is the detailed tutorial.

Error 0x800701B1 on Windows 10 [Solved] - Best IT Guide (3)

Step 1: Right-click the Start button and choose Device Manager.

Step 2: In Device Manager, double-click the Drives category to expand it. Then right-click on your USB drive and select Update driver.

Step 3: In the pop-up window, select Search automatically for updated driver software. Then follow patiently when the latest driver is downloaded and installed.

Step 4: Once the driver update is installed, restart your computer.

Step 5: If error 0x800701B1 appears again, go to Device Manager, right click on your USB drive and select Uninstall device. After uninstalling the driver, restart your computer and the driver will be reinstalled automatically.

Solution 4: Upgrade your power supply (desktop only)

Error 0x800701B1 on Windows 10 [Solved] - Best IT Guide (4)

If none of the above methods worked for you, you can start investigating your power supply (AC adapter). If you are experiencing this issue on a desktop device, your power supply may not be providing enough power to meet the needs of all your PC components.

Keep in mind that an SSD requires around 3 watts, while regular 3.5 HDDs require around 10 watts of power. Depending on the rest of the components (especially if you have a demanding graphics card), your PSU may not be able to cover them.
If you currently have an additional peripheral connected, unplug any non-essential ones and see if the problem goes away.

If the error code goes away while unneeded peripherals are disconnected, it is clear that the problem is with the PSU - in this case, you must choose a PSU with more than 500W (real capacity).

Solution 5: Change USB drive security options

Another reason for error 0x800701B1 "a nonexistent device was specified" is that you are not allowed to access your USB drive due to security permission issues. To fix the error, you need to change the security settings for your USB drive by following the steps below.

Step 1: Press Win + E to open File Explorer.

Step 2: Click This PC in the left pane and right click on your USB drive. In the pop-up window, select Properties.

Step 7: Click Apply and OK to keep the change.

Now you can check if error 0x800701B1 has been fixed.

Solution 6: Run a Check Disk Scan of the USB drive

USB flash drive may display device not specified error if the drive has logical file system errors. In this case, running a Check Disk (CHKDSK) scan of the drive may solve the problem.

(Video) Fix Error 0x800701b1, A device which does not exist was specified error in Windows 11/10/8/7

Step 1: Run a CHKDSK scan of the drive and wait for the process to complete (it may take some time).

Step 2: Once the CHKDSK process is complete (without any issues), check if the system is no longer showing flash drive error.

Step 3: If the problem persists, disconnect the USB drive and shut down (do not reboot) your system.

Step 4: Then power on the system with necessities and plug in the USB again to check if the USB drive works normally.

If the problem persists, check if the drive works fine on another system (preferably with a different operating system). If yes, format it on that system and then try on your system. If the problem persists, you can try a third-party application (e.g. Diskinternals Uneraser) to solve the problem or have the USB drive checked for hardware errors elsewhere (you can change the USB controller to solve the problem ).

Solution 7: Replace your external hard drive

Maybe your external hard drive is the culprit. As the hard drive wears out, errors and glitches become the norm. Test if error 0X800701B1 still occurs when using a different hard drive.

With the error resolved, you should consider buying a new external hard drive, or even better, an SSD if you really want to upgrade your gear.

frequently asked Questions

What is power supply?

A power supply unit (PSU) converts AC power to low-voltage regulated DC power for a computer's internal components. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch to select the input voltage, others automatically adjust to the mains voltage.

Most modern desktop PC power supplies conform to the ATX specification, which includes form factor and voltage tolerances. While an ATX power supply is connected to AC power, it always provides a 5-volt (5 VSB) standby power supply to power the computer's standby functions and certain peripherals. ATX power supplies are turned on and off by a signal from the motherboard.
