The request failed due to a fatal device hardware - WD Hard drive

I purchased a 14TB External Hard Drive (WDBWLG0140HBK-NESN) off of Amazon from the US (I’m in Australia) to use on my MSI GE70PE Apache Pro.
However, when I plug it in, I can hear it, but not see it.
I googled the problem & found a solution “Disk Management”, but got this error message.


Then I tried WD Diagnostics

No luck either.

When “the request failed due to fatal device hardware error” occurs, your device turns inaccessible. This error usually occurs while attempting to transfer/copy files and suddenly the Windows OS fails to recognize the input or the output devices. In addition, this error could also be due to a fault in the systems hardware, inappropriate configuration, loose connections, etc.

To fix the error you can try the below DIY methods:

  1. Check the SMART status
  2. Run an error check
  3. Run CHKDSK scan
  4. Initialize the disk

Further, you can check the below blog to know more troubleshooting methods that can help to resolve the issue and also helps to recover data from such drive:

Hope it helps!

Drive #8 WD Elements 25A3 (USB) with Serial Number: RANDOM_F1E4DB90

With a Serial Number like that … I would say with 100% confidence that it’s a FAKE Hard drive. Drive #4 Serial Number (VCG5Y6KN) also looks very suspicious.

Geniune WD Hard Drives serial Start with a W as you can see with your other drives.

If you enter Drive#8 and Drive#4 Serial Number into WD’s Warranty Check … they won’t be accepted.

You may as well disassemble the 14TB External enclosure to see what fakery is inside … you can bet it won’t be a 14TB WD Hard drive.

Post photos here to serve as a warning buying from Amazon

In future too, if you’re AU … and buy a legit Hard drive from the US, and claim warranty from the manufacturer … The warranty won’t be covered in AU and you’ll have to ship it back to the US for the warranty claim.

Buy local.

The site appears to be genuine.
I bought a 10TB External Hard Drive back in December 2020 & it works fine.
My P/N: WDBWLG…BK-XB.
Is there a difference between WDBWLG0140HBK-NESN & WDBBKG0140HBK-AESN

It’s brand new out of the box.
To do any sort of CHKDSK I would need to see the drive.
I already tried to Initialise the disk & it gave an error message (as shown).

I suggest you to give a try to below mentioned 2 different methods to resolve the issue:

Method 1. Use Disk Management to fix not initialized error on external hard drive

  1. Connect uninitialized external hard drive to your PC.
  2. Press Win + R keys, type: diskmgmt.msc and hit Enter.
  3. Find the uninitialized, unknown external hard drive with I/O device error > Right-click on it and select Initialize Disk.
  4. Then set the disk to initialize and set disk as MBR or GPT.

After this, you may reboot your PC and keep all changes. Now, your external hard drive will be recognized and read by Windows again.

Method 2. Run CMD to repair I/O device error on not initialized external hard drive

This CMD command would erase all data on the uninitialized hard drive, which you can later restore after repairing the external hard drive not initialized, with the help of any data recovery or partition recovery software:

  1. Press Win+R > Type: diskpart and hit Enter.
  2. Type: list disk and hit Enter.
  3. Type: select disk F and hit Enter; (replace F with the drive letter of an uninitialized external hard drive).
  4. Type: clean and hit Enter.
  5. Type: convert gpt or convert mbr and hit Enter.
  6. Type: create partition primary and hit Enter.
  7. Type: format quick fs=ntfs and hit Enter.
  8. Type: assign and hit Enter.
  9. Type: exit and hit Enter.

Try & check if this helps!
