What is the fatal device hardware error?    

“Request failed due to fatal device hardware” is an error message that you can get any time after or while you are trying to copy content from a drive. 

The message prompt will prevent you from accessing the drive’s contents. And to be honest, the thought of never seeing your valuable data can be unnerving. 

But often, it happens that you get the message even when there is no damage to your hardware. Thus, it is easy to fix fatal device hardware error on the external hard drive or internal driver.

Some common causes for the error prompt include

  • If the error is being prompted for an external hard drive connected via a cable, the cable might be loose or faulty. This can make the data unreachable and thus, the error is prompted.
  • The hard drive that you are using could be corrupt or have multiple bad sectors. 
  • Instead of the external hard drive, the device you are using to access it could also be damaged.
     

Trivia about the fatal device hardware error

Western Digital and Seagate external hard drive users are the most likely to face this kind of an issue. 

Also, you could be seeing multiple variants of the error prompt.

5 simple and tested ways to fix fatal device hardware error on an external hard drive 

1. Check connecting cables

As mentioned earlier, the error can occur if the cable connecting the external drive to the device is loose or malfunctioning.

In such a situation, you can fix fatal device hardware error on the external hard drive in the following ways:

  • See if the connection is loose. If yes, push the cable firmly into the port.
  • Pull out the cable and reconnect it again.
  • Try using another port for inserting the cable and connecting it to the external hard drive.
  • Replace the USB cable that you are using.
  • Try using the cable with another desktop or laptop to identify if the problem is with the device, connecting cable, or external hard drive.

If none of these ways works, it means that the USB cable is fine and there is something wrong with your external hard drive. But again, you don’t need to panic.

2. Verify the SMART status

The Self-Monitoring, Analysis, and Reporting Technology (SMART) is a great way to check your hard drive’s status. It can automatically monitor and detect when a hard drive is failing. 

Whether you are using a Windows device or a Mac device, you can manually check the SMART status of the external device that is prompting the error. 

To check the SMART status of your external hard drive,

Step 1 - Press the Windows Key + X
Step 2 - Click on “Command Prompt (Admin)”. 
You can also search “Command Prompt” in the search bar on your taskbar. Then click “Run As Administrator”.

You will see a dialogue box asking if you would like Command Prompt to make changes to your device. Press “Yes”.

Step 3 - When the command prompt opens, copy and paste “wmic diskdrive get status” there and press Enter.

The command will return one of the following statuses:

  • Ok - You don’t need to worry about your hard drive. Try the fix number 3 or 4.
  • Bad or Unknown -  Use the fix number 3, 4 or 5. You should also use data recovery software for your external hard drive to avoid data loss later.
  • Caution - This status signals that something is seriously wrong with your hard drive. It is best to take it to an expert for repair.

If your external hard drive’s drivers are outdated or dysfunctional, you can update them to fix the “Request failed due to fatal device hardware” error.

To check and update the driver, follow the steps below:

Step 1 - Type device manager in the search box on your taskbar. (If you don’t have the search bar on your taskbar by default, press the Windows key + S to open it.)

Step 5 - Follow the on-screen instructions and wait for the process to complete.

Step 6 - Restart your device before trying to access the external hard drive again.
