[FIXED] The Request Failed Due to a Fatal Device Hardware Error

Have you ever experienced “your computer is low on memory“, “your pc ran into a problem and needs to restart” or “the request failed due to a fatal device hardware error” issue? If so, you might have also experienced that your device becomes inaccessible after seeing this message. Such an issue generally occurs when you try to move or copy a file from or to another device. During the transfer, the Windows OS will show this message as it cannot recognize the linked device. Furthermore, you must know that there can be several possible causes behind this issue. For instance, it can occur due to the wrong hardware configuration, bad system hardware, improper connection, etc.

Well, what should you do after noticing “the request failed due to a fatal device hardware error“? First, let’s try some simple solutions and resolve the issue. In most of the cases, these basic solutions might be able to resolve this issue.

Part 1. Basic solutions to fix “the request failed due to a fatal device hardware error.”

  • Connect the device to a different computer
  • Use a different USB cable to see if it works
  • Change the letter of the drive
  • Update the drivers and see if the problem is resolved

In addition to that, you should know that hard drives tend to fail once in a while. More importantly, such failure can happen at any given moment. Even an expert will not be able to foresee the errors related to hardware components. In the event of a hardware failure, the obvious outcome is data loss. Upon hard drive failures, you will not be able to access the data stored in it. The most practical precautionary method to minimize the data losses associated with hardware failure is creating backups. You should make it a habit to backup the important data of your hard drives on a regular basis. Such approach lets you recover data if you lost them due to one reason or another.

Part 2. Other ways to analyze your hard drive’s status

If you want to use built-in feature of Windows OS and try to troubleshoot the drive, read on. One of the most basic but effective options you should consider is SMART technology. The term SMART is the abbreviation to Self-Monitoring, Analysis, and Reporting Technology). In addition to that, there are several other options you can try to troubleshoot the error.

1. Check for SMART attributes of the device

One of the most basic yet effective methods you should try is to use the WMIC method. WMIC refers to the process of Windows Management Instrumentation Command-Line. This interface lets you check if the hard drive is in optimal health. To access this feature, you should follow the steps mentioned below.

Go to command prompt box and then type in “wmic disk drive get status

If everything is fine and your hard drives are functioning at their optimal conditions, “OK” status will be displayed. This message will be displayed in front of the respective disk drive. But, if the hard drive is experiencing some issues, you will see a different status. For instance, you would see a status like “Caution“, “Unknown” or even “Bad“.

After noticing an error status on your hard drive, you should know that there is something wrong with it. So, the smartest move is to create a backup of the faulty hard drive before it gets inaccessible. After backing up the valuable data, you should probably replace the faulty hard drive with a new one. This approach would make it possible for you to run the computer smoothly and prevent from losing data.

Important: After noticing a SMART error, you should act as fast as you can. Your hard drive can become completely inaccessible at any given moment. So, try to stop using that hard drive and transfer all the data to a new drive.

2. Perform an error check

If you cannot access the disk at the moment, you can use the Disk Error Checking feature. Also, this process might increase the overall performance of the computer. Running a Disk Error Checking would fix all the bad sectors, errors in the file system, etc. To do this, you should follow the steps mentioned below.

  • Right click on the faulty hard drive
  • Click on the option labeled “Properties” on the popup menu
  • Switch to the “Tools” tab found under “Error-checking” option and then click on “Check

If there is a system error, the message will be displayed, and it will start to scan the drive. At the completion of the scan, you will have to restart the PC. If not, you should let the PC fix the errors when it restarts for the next time.

3. Use Diskpart Utility

With the use of Diskpart Utility, you will be able to resolve a variety of issues. This can be considered as one of the most widely used methods to troubleshoot potential errors. This is a very handy tool that helps to maintain disks with optimal performance. Apart from checking the disks for potential hard drive errors, it can even repair the potential errors. To do that, you should follow the steps that are mentioned below.

  • Go to the Command Prompt on your PC on which the faulty hard drive is installed
  • Type in CHKDSK/F so the system will be able to fix the system file errors
  • If you need to perform a scan on the hard drive for bad sectors, type in CHKDSK/R

4. Initialize the faulty hard drive

If the hard drive is still not accessible, you will need to try initializing it. By initializing the disk, you can also expect to eliminate the potential error called “Disk Unknown Not Initialized“.

Mentioned below are the steps you should follow to initialize the faulty hard drive.

  • Go to Disk Management. You can run this from the Start Menu. For Windows 10 and 8, the command you should type is “diskmgmt.msc“. For Windows 7, you should go to Manage (after right-clicking on the computer) and then go to Disk Management.
  • Then, you should right-click on the hard drive and click on “Initialize Disk“.
  • You should then select the option “Master Boot Record” (MBR) or GPT (GUID Partition Table) to start initializing.

Please note that initializing the disk would delete all the data on the respective disk. So, make sure that you have created a backup of the relevant data before initializing the disk.

If you wrongfully use the command lines, you can accidentally zero the hard disk. It might make the situation worse.
