"The request failed because of a fatal device hardware problem" occurs frequently, resulting in fatal problems such as data loss and inaccessible drive. You can find the corresponding solutions in this post.

Part 1: The request failed due to a fatal device hardware problem

Have you experienced the problem "The request failed because of a critical device hardware failure"? Do you know what this exactly means? And do you want to restore the data from the device that is experiencing this problem? I think the answers to these questions are "yes", "no" and "yes".

The device's serious hardware error (as long as the error persists, the drive becomes inaccessible) now shows and then also on various devices (WD external hard disk drives and Seagate hard disk drives are the 2 most common devices).

Fatal error on the WD and Seagate hard drive

Now let's take a look at the following real case.

1. Fatal device error with the WD hard drive

Hi, my name is Brianne and I am having problems with the WD external hard drive. I'm not sure if purchasing your program will help. First of all, I am a computer illiterate. When I connected my external hard drive to my computer, I can open it on the PC, but I couldn't see any data on it. After researching my problem on Google, I found that calling Disk Management and changing the drive letter fixed the problem. However, my external hard drive showed up as “Disk 1, unknown, not initialized”. After further research, I realized that I need to initialize the disk by recreating MBR. I had no idea what it meant. But I followed the instructions and received the message: The request failed due to a fatal device hardware error. Your program was suggested to me, but I didn't know what to do to fix the problem, nor did I know if your program was doing something I needed. Can you help me?

2. Seagate Hard Drive Fatal Failure

I recently bought a new hard drive because my old one stopped working. It's a Seagate 2Terabyte internal hard drive, when I plugged it into my Windows 10 computer, I see on the screen that 0.0 is the memory space left. So I plugged it back into my laptop (using a SATA cable that I bought) to see what it was. But I couldn't do anything about it or even format it. I thought maybe I had to initialize it. But it was labeled as unknown in Disk Management and could not be initialized. Then came the message that the request failed due to a fatal device hardware error. I was confused. Why did that happen? It's a new hard drive that I recently bought. Can someone help me? By Mr. Ashy, a visitor on Tech Support Guy Forums

The best solution for the serious hardware failure of the device

In fact, few people know the reasons why their drives have suddenly become unavailable and come up with such a fatal error. But one should rather worry about how to restore the data from the inaccessible hard disk drive and fix the serious hardware failure of the device.

Since for most people the data is far more important than the drive itself, and there is often a lot of valuable data stored on the drive, I think it makes sense to teach you how to recover the data from the inaccessible drive. During this process, the powerful program, MiniTool Power Data Recovery, can be your good assistant.

Advanced Features of MiniTool Power Date Recovery:

  • It is multi-functional (can recover data from both inaccessible partition and unallocated / initialized disk).
  • It has higher compatibility (supports USB drives, SD cards, hard drives, and other common storage devices).
  • Besides, it has a simple and easy to use interface so that the inexperienced computer user can handle the problems with ease.
  • Most importantly, your data is secured with it. Because this gives you a copy of the data.

Part 2: File Recovery from Inaccessible Drive

If you have the fatal hardware failure on the SD card or other storage device, it doesn't mean the end of the world; On the other hand, you may still have a chance to recover the important data on the problematic drive and fix the error if possible.

Even if you want to fix the critical device hardware error, you would always have to restore the data from the inaccessible drive first. If all of the data you need is successfully restored from the drive where the error happened, then you can try the possible methods one at a time to resolve the fatal device hardware failure.

For data recovery, you can start with a trial version first to try the performance of MiniTool Power Data Recovery first by installing and running it on your computer.

How to recover the data from the inaccessible drive

However, the trial version will not be able to restore the data for you. I'll be the one herePersonal version take the following part as an example to show you how to recover data from inaccessible drive.

Step 1: Choose the most suitable option from the left pane

If you can see the hard drive and its partitions through Windows Explorer, but the error message “Access is denied When accessing the hard drive, you should run "This PC".

Unless an internal drive is involved, the first thing you should do is connect your device to the computer to check whether or not it can be viewed on Windows Explorer.

  • If the drive is shown but you cannot access it, you should run MiniTool Power Data Recovery software and select Removable Storage mode. (You can select Hard Drive mode if your removable media is a hard drive)
  • If you don't see it, then you should read this post: How to Fix USB Drive Not Recognized & Data Recovery to grab problem and fix error.

Please make sure that you will only be able to restore the data from the inaccessible drive if the drive can be recognized by Windows Disk Management. If the disk does not appear in Windows Explorer, but appears in Disk Management as "not assigned", "not initialized", or "unknown", you can refer to the following article to solve the problem of an unknown drive.

You can read this article:My drive cannot be used on dem Windows Explorer are displayed to find a suitable solution offered by Microsoft.

Step 2: Select the correct drive or partition from the right pane to scan.

You should select the exact drive or partition that has become inaccessible and is reporting the fatal device hardware failure. Then click the Scan button in the lower right corner of the main interface to start scanning the files.

Note: The Settings button can help you choose the specific file types. You can click on it and choose the data types you want and hit the OK button to give the confirmation. The software will then only display files of these data types under the scan results.

Note: If you forget to connect the USB drive or external hard drive to the computer, this is the time to plug it in and switch to the other option. Then switch back to the original on the left pane to refresh the list. With this step, your removable media should appear after the update.

Step 3: Check all the files & folders you need to restore

No matter which option you have selected and which partition or drive you are scanning, you will be shown more than one partition during the scan. At the same time, you also have other tasks to do.

  • Please open all the partitions and folders found to browse the files on them.
  • Please open the files below to check which files you need and which you don't.

If you have previously stored a large amount of files on the disk, this process can take a long time and it could become boring. But you should still be careful all the time.

Please note that the "Preview", "Filter" and "Search" functions are also able to make scanning the files much easier.

  • The "Preview" function enables you to check the content of the image / photo / text files.
  • The "Find" function is able to search for an exact file by entering the file name.
  • Filtering (also known as advanced filtering) is useful when you prefer to search for data by file name extension or by file size or when the files were created.

Step 4: Provide a safe storage directory for the files that will be restored.

After you have ticked and selected all the files you want to restore, you should hit the Save button in the bottom right. You will then see a window: A folder to save the files. Obviously, you should choose a path for the files you've checked.

Please pay attention to the following 2 things:

  1. Select the original USB drive or hard disk drive with the fatal device hardware error as the target path of the storage directory.
  2. Make sure that there is enough free space on the destination drive to restore all of the files you have selected.

After verifying, click the OK button below for confirmation.

You will wait for some time before all the files are saved to the destination drive. And when you see a window saying that the files have finished saving, you can then go back to see if you really got the files you want to restore or not.

Note: When everything is there, you can close the MiniTool Power Data Recovery software. If you are still concerned that the files you want to restore still exist, you can click the Export Scan Results button to save the current scan results to your drive. You are welcome to add the “Load manually” function to the main software interface so that you can import the results no matter when you want to load them.
