Windows 10 Anniversary Update includes a new Storage Diagnostic tool to diagnose various aspects of drives connected to your PC. If your suspect your disk drive of a problem, the Storage Diagnostic tool can be useful in identifying the issue since it collects various data about drives and the file system.

The new tool is named StorDiag.exe. It collects storage and filesystem diagnostic logs and outputs them to a folder. It is a console tool, which can be accessed using the command prompt. It can save time by running all necessary tests automatically by running a single command.

The program supports three parameters that you can run it with. You may run stordiag.exe /? first to display them on the screen.To Run This Open an elevated command prompt. Right click on Windows 10 Start Menu And Select Command Prompt ( admin ) this will open the Command prompt window.

Now Type : stordiag.exe /? 


This will output bellow

StorDiag [-collectEtw] [-out ]
-collectEtw  Collect a 30-second long ETW trace if run from an elevated session
-checkFSConsistency  Checks for the consistency of the NTFS file system
-out   Specify the output path. If not specified, logs are saved to %TEMP%StorDiag

Now to collect a ETW (Event Tracing for Windows) trace and check file system consistency, generate diagnostics logs and save them to your Desktop, run the following command:
stordiag.exe -collectEtw -checkFSConsistency -out %userprofile%\desktop



Once you start the task, you will see it carrying out several tasks, including running of ChkDsk, FSUtil, and so on. So instead of running tests individually, it will run several tests automatically.

 on your desktop.


You find the massive list of log files and event files in the -out directory afterwards.
