Section 1: About The Request Failed Due To A Fatal Device Hardware Error
Have you ever met "the request failed due to a fatal device hardware error"? Do you know what does this mean exactly? And do you want to recover data from the device on which such error appears? We guess the answers to those questions are "yes", "no" and "yes".
The not accessible fatal device hardware error (once this error occurs on a drive, that drive will become not accessible) shows up now and then on different devices (WD external hard drive and Seagate hard drive are two most common devices). Now, let's take a look at the following cases.
Hard Disk Fatal Error Appears on WD Drive & Seagate Drive
- WD fatal error device discovery:
"Hi my name is Brianne and I've run into some issues with my WD my passport external hard drive and I'm unsure if purchasing your program will help. First off, I am computer illiterate! When I plug in my external drive, it shows up in my devices but I'm unable to view anything. After googling my issue I found that going to disk management and changing the letter would fix the problem however, my external drive shows up as "disk 1, unknown, not initialized". After more googling I found that I need to initialize my hard drive by rebuilding MBR. Again, I have no idea what any of this means but I follow the instructions and I get an error message "The request failed due to a fatal device hardware error". Your program was suggested but I'm not sure what needs to be done to fix my issue and if your program does whatever I need. Can you please help me?"- from Ball, Brianne, a potential customer of MiniTool
- Seagate fatal error device discovery:
"I just bought a new hard drive because my last one ended up not working. It's a 2 Terabyte Hard internal hard drive from Seagate. When I put it in my computer to install Windows 10, it said it had 0.0 space left. So I connect it to my laptop (with a sata cord I bought) to see what's the issue and I can't do anything to it. Can't format it (I think it needs to be initialized first cause currently, disk management has it labeled as unknown), can't initialize it (Says request failed due to fatal device hardware error) can't delete anything either. I'm so perplexed because this is a new hard drive, why is this happening?"- from Mr.Ashy, a visitor on Tech Support Guy Forums
The Best Fatal Device Hardware Error Solution
In reality, few people know the reason why their drives become unavailable suddenly and give such a fatal error message. But what they're more concerned about is how they can recover data from inaccessible drive or how to fix the fatal device hardware error.
Considering that data is more important than the drive itself to most people and that there are often many valuable data on it when the hard drive is not accessible, we make the decision to teach you how to recover data from the not accessible flash drive/hard drive. During this process, MiniTool Power Data Recovery becomes a necessity.
It is really powerful (be able to recover data from both inaccessible partition and unallocated/initialized disk) and has high compatibility (gives support to USB flash drive, SD card, hard drive and other common storage devices). What's more, it is provided with wizard-style interfaces so that even inexperienced computer users can handle it effortlessly.
Section 2: Recover Files from Not Accessible Drive
No matter you want to fix fatal hardware error on hard drive or on SD card, the first thing to do should always be data recovery from the not accessible drive. When all your needed files have been recovered successfully from the drive on which such error occurs, you can try all sorts of possible ways to fix fatal device hardware error.
As for the data recovery, of course, you can download MiniTool Power Data Recovery Free Edition V7.0 immediately and install & launch it to start. But we think this is not the best choice. That is because we guess the size of your files on the inaccessible flash drive or hard drive is often larger than 1GB, while the free edition of software has a 1GB free recovery limit. Therefore, we recommend that you choose a personal edition to break the limit.
How to Recover Data from Inaccessible Hard Disk
In the following content, we'll just take the Personal License as an example to show you how to recover data from not accessible drive in detail.
Step 1: choose the functional module that is most suitable for your case.
- If you can see the hard disk and its partitions in Windows Explorer, but receive an access is denied error when trying to access it, you should run MiniTool Power Data Recovery immediately and choose "Damaged Partition Recovery".
- You need to connect your device to the computer first when it is not an internal hard drive, in order to see whether it appears in Windows Explorer or not.
a). If the flash drive shows up, but you fail to access it, you should run MiniTool Power Data Recovery and choose "Damaged Partition Recovery".
b). If it doesn't appear, you should read USB Flash Drive Not Recognized – Don't Worry Too Much to try to figure out the problem and then fix it.
You are able to recover data from inaccessible flash drive only when it can be recognized by Windows Disk Management.
- If the disk doesn't show up in Windows Explorer but does appear in Disk Management, marked with the label of "Unallocated", "Not Initialized" or "Unknown", you need to choose "Lost Partition Recovery" after launching MiniTool Power Data Recovery.
You can also read My Drive does not appear in Windows Explorer view to find proper resolutions provided by Microsoft.
Step 2: select the correct disk or partition to scan.
- If you choose "Damaged Partition Recovery" in the first step, you need to select the exact partition that becomes not accessible and gives you the not accessible fatal device hardware error when you tried to open it. Then, click on "Full Scan" button at the bottom of the software interface to start detecting files.
Note: the "Open" button next to the "Full Scan" button is only able to help you directly enter the drive which cannot be identified by Windows sometimes. But even if you have entered it successfully, it is common that not all the data you needed are displayed here. So we suggest using "Full Scan" in this case.
- If you choose "Lost Partition Recovery" instead, you need to select the unallocated/unknown/not initialized hard drive with a fatal hardware error. Then, you also should click on "Full Scan" button in order to search for files originally included on the disk.
If you're curious about how to recover data from HDD shows as unknown, not initialized and unallocated, you'd better read this passage; it tells all situations you want to know.
Step 3: check all the needed files & folders to recover.
No matter what function you choose – "Damaged Partition Recovery" or "Lost Partition Recovery", you'll be provided with more than one partition when the full scan is finished. At this time, you've got a lot of work to do.
You have to open all the found folders one by one to browse the files inside so as to pick out which ones are needed and which ones are not. If you have ever stored large amounts of data on the disk, this process would be long and boring, but you need to be careful all the time.
a). "Preview" helps you to view the content of a picture/photo/txt file before you check it.
b). "Find" function is able to search for an exact file by typing filename.
c). "Filter" function (also called Advanced Filter) is useful when you prefer to search for files by file extension, file size or file creation/modification date.
Step 4: set a safe storage directory for the files waiting to be recovered.
After adding a check mark in the square box in front of all the files you plan to recover, you should click on "Save" button in the lower right corner to see the "Select a directory to save files:" window. Obviously, you need to select a storage path for the files you've checked.
And you must pay attention to the following two things:
b). please make sure that the target storage drive has enough free space to store all the files you've selected to recover in step 3.
After making your decision, you ought to click on "OK" button below to confirm.
You'll need to wait for a short time before all the files are saved to the destination drive. And when you see a pop-up window, saying "OK! The selected files have been saved to *" (* stands for the destination drive), you can go to check the recovered files.
If that's all you need, you may close MiniTool Power Data Recovery now. If you're worrying that there may be files that you need but forget to recover, you may click on the "Export Scan Result" (next to "Filter") to save the current scan result to your drive, and then make use of the "Load manually saved scan result" function to import the result whenever you want.

Reformat The Drive
Open Windows Disk Management -> find the inaccessible flash drive/hard drive -> right-click on it and choose "Format…" -> set a proper volume label, file system and allocation unit size (you can also keep the default information provided by system) -> click on "OK" button to confirm in the same interface -> click on "OK" button in another pop-up window to start formatting -> wait for the completion.
Tip: you can also make use of the "Format Partition" or "Wipe Partition" function of MiniTool Partition Wizard if above method ends up in failure.
Initialize The Disk
Open the Windows Disk Management -> right-click on the "Unknown" & "Not Initialized" disk if the "Initialize Disk" Window doesn't pop up automatically -> choose a partition style (MBR or GPT) for the selected disk -> click on "OK" button to confirm your selection.
In addition to above two methods, you can also try to change USB port or computer, check & shield bad sectors or replace the bad component (such as the magnetic head) to fix the fatal device hardware error.
