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:
