Stordiag Exe Is The Newest Windows 10 Storage Diagnostic Tool

Users who want to analyze storage on their Windows 10 devices can take advantage of the new diagnostic tool called StorDiag.exe, which was added to the Anniversary Update. So, if there are any storage related issues or if the NTFS file system has been corrupted, this program will detect any kind of problem. In this article we’ll tell you more about StorDiag.exe and what it can do.

With the help of StorDiag.exe, users will run an ETW trace, check the logs, Registry files and event files that are created by application, after it’s done with the processing. Users will not even notice or they will forget that StorDiag.exe will run in the background, including in file system utility, in the Fltmc.exe control program or CheckDisk.

StorDiag.exe was introduced in Windows 10’s Anniversary Edition and these are the steps that users must take if they want to run it.

First of all, they will open an elevated command prompt by tapping the Windows-key, typing cmd.exe, holding down the Ctrl and Shift keys, then choosing the Return key and confirming the UAC prompt that will appear. This will open the elevated command prompt window, which should read Administrator in the title.

There are three supported parameters that allow users to run the program, and they will be displayed on the screen after running stordiag.exe /?.

-collectEtw will collect a 30-second long ETW trace if run from an elevated session; -checkFSConsistency will check for the consistency of the NTFS file system; -out will specify the output path and if it doesn’t specify it, it saves logs to %TEMP%\StorDiag.

Users will run storage diagnostics if they’ll use the following command:

stordiag.exe -collectEtw -checkFSConsistency -out c:\users\YOUR USERNAME ON YOUR SYSTEM\desktop

After a few minutes, the processing will end and the program will collect a 30 second ETW trace. If there will be found any issues, StorDiag.exe won’t fix them, which means that only users will correct them.
