Fix The request failed due to a fatal device hardware error in Windows 10

Hard drives and external drives by genuine brands are durable enough. However, at times, they could go bad or get physically damaged. In such a situation, the user would get the following error:

The request failed due to a fatal device hardware error.

The Request Failed Due To A Fatal Device Hardware Error.

Cause

The cause could be that the hard drive or internal drive is either damaged physically or its files are corrupt. In case the issue is with the hardware itself, we could either try changing the cables and checking if it works, else the hardware needs to be replaced.

We could perform the following steps before replacing the hardware:

1} Try connecting the external disk to a different system

2} SMART analysis of the hard drive

3} Run the CHKDSK command

4} Format the external drive

 

Solution 1] Try connecting the external disk to a different system

In case of eternal drives like a USB drive, to check whether the issue is with the system or the drive itself, try connecting the external disk to a different system and check if it works fine. If it doesn’t, try replacing the connecting cables (in case it uses USB port cables to connect to the system) and check if it works after that.

 

Solution 2] SMART analysis of the hard drive

Windows allows users to analyze issues with the hard drive using a command line.

1] Search for Command Prompt in the Windows search bar and right-click on the icon. Select Run as administrator.

2] Type the following command in administrative command prompt:

 

wmic diskdrive get status

Disk Drive Status

 

3] Press Enter to execute the command.

In case the outcome is ‘Bad’ or ‘Caution’, it refers to an issue with the hard drive’s physical hardware, which would have to be replaced. In case the outcome is ‘Unknown’ or ‘ok’, we could proceed to the next solution.

Solution 3] Run the CHKDSK command

The CHKDSK command helps check bad sectors in the hard disk and repair them if possible.

1] Open Command Prompt as administrator (as explained in Solution 1), and type the following command:

 

CHKDSK /f /r

Chkdsk

 

3] When you press Enter after the command, it would prompt whether you are sure that that you wish to run the CHKDSK command.

4] Type Y (to represent Yes) and press Enter.

The CHKDSK scan would run after you restart the system.

 

Solution 4] Format the external drive

While we have little options with internal drives, we could try formatting external drives.



1] Insert the external drive (eg. a USB drive) and right-click on it. Select Format.

2] In the Format window, check the box for Quick Format and click on Start to initiate the formatting process.

Format Usb

3] Pull the USB or external drive out and reinsert it.
