The Windows 10 Redstone 1 update silently adds a new console tool (StorDiag.exe) which can be used to collect storage and file system diagnostic logs. This is a useful tool for identifying problems with your hard drive or the file system, and the collected data can be helpful for troubleshooting purposes.<\/p>\n

Running StorDiag.exe<\/h2>\n

Open Command Prompt (Admin)<\/a> and type:<\/p>\n

StorDiag.exe \/?<\/pre>\n
This shows the following information:<\/p>\n
\n
Collects storage and filesystem diagnostic logs and outputs them to a folder.<\/p>\n
StorDiag [-collectEtw] [-out <PATH>]<\/pre>\n\n\n\n\n\n\n\n\n\n\n
Argument<\/b><\/td>\nDescription<\/b><\/td>\n<\/tr>\n
-collectEtw<\/td>\nCollect a 30-second long ETW trace if run from an elevated session<\/td>\n<\/tr>\n
-checkFSConsistency<\/td>\nChecks for the consistency of the NTFS file system<\/td>\n<\/tr>\n
-collectPerf<\/td>\nCollect disk performance counters<\/td>\n<\/tr>\n
-diagnostic<\/td>\noutputs a storage diagnostic report<\/td>\n<\/tr>\n
-bootdiag<\/td>\noutput boot sectors of the disk<\/td>\n<\/tr>\n
-driverdiag<\/td>\noutput available storport and storahci logs<\/td>\n<\/tr>\n
-out <PATH><\/td>\nSpecify the output path. If not specified, logs are saved to %TEMP%\\StorDiag<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
To check for file system consistency, run the following command:<\/p>\n
stordiag.exe -checkFSConsistency -out %userprofile%\\desktop<\/pre>\n
This tool gets the list of volumes and runs Chkdsk on each of the volumes (without repairing), exports the registry keys for each storage device as well as file system related settings, exports several event logs (relating to disk drives and file system) to separate .evtx files. It also gets storage reliability counters for each volume and stores the output to a text file named PSLogs.txt. Here is the list of log files this tool generates:<\/p>\n
ChkDsk C.txt\r\nChkDsk D.txt\r\nPSLogs.txt\r\nVolume C Corruption.txt\r\nVolume D Corruption.txt\r\nCDROM.reg\r\nDiskDrive.reg\r\nFileSystem.reg\r\nHDC.reg\r\nSCSIAdapter.reg\r\nVolMgr.reg\r\nVolSnap.reg\r\nVolume.reg\r\nMicrosoft-Windows-DataIntegrityScan-Admin.evtx\r\nMicrosoft-Windows-DataIntegrityScan-CrashRecovery.evtx\r\nMicrosoft-Windows-DiskDiagnostic.evtx\r\nMicrosoft-Windows-Ntfs.evtx\r\nMicrosoft-Windows-Partition.evtx\r\nMicrosoft-Windows-Storage-ATAPort.evtx\r\nMicrosoft-Windows-Storage-ClassPnp.evtx\r\nMicrosoft-Windows-StorageManagement-Operational.evtx\r\nMicrosoft-Windows-StorageSpaces-Driver-Diagnostic.evtx\r\nMicrosoft-Windows-StorageSpaces-Driver-Operational.evtx\r\nMicrosoft-Windows-StorageSpaces-SpaceManager-Operational.evtx\r\nMicrosoft-Windows-Storage-Storport.evtx\r\nMicrosoft-Windows-Volume.evtx\r\nMicrosoft-Windows-VolumeSnapshot-Driver.evtx\r\nSystem.evtx\r\n<\/code><\/pre>\n
As said earlier this is only a data collection tool which launches other console tools like chkdsk, fsutil, etc., in the background, and doesn’t fix anything. It’s a nice addition to Windows 10 anyway.<\/p>\n","protected":false},"excerpt":{"rendered":"
