CHKDSK.exe (test disk) is a classical built-in Windows software for checking exhausting drives for errors. The chkdsk permits you to test your disk and file system for bodily and logical errors, discover unhealthy sectors and repair issues discovered. In this text, we’ll have a look at the specifics of utilizing the chkdsk software in Windows 10, in addition to a approach to test the disk utilizing the Repair-Volume PowerShell cmdlet.
The chkdsk in Windows 10 permits you to test and repair exhausting drives with NTFS and FAT32 file techniques. Chkdsk is just not relevant to ReFS volumes as a result of they use totally different information integrity applied sciences.
How to Check Disk for Errors Using CHKDSK on Windows 10?
To test your exhausting drive for errors, run the elevated command immediate (with administrator permissions). Then, run the command:
chkdsk E: /F /R
This command will begin E: drive checking, the errors discovered will likely be mounted routinely (/F), if there are unhealthy sectors, an try will likely be made to get better the information (/R). A full disk test could take a very long time relying in your storage capability and the variety of information.
The chkdsk software performs 4 sequential passes to test quantity metadata:
- Stage 1 – verifying information;
- Stage 2 – verifying indexes;
- Stage three – verifying safety descriptors;
- Stage four – verifying Usn Journal and sectors.
After finishing the disk test, you will note detailed disk statistics, details about unhealthy sectors and information, in addition to the steps taken to get better information.
If the chkdsk utility discovered no issues, the next message will seem:
Windows has scanned the file system and discovered no issues.No additional motion is required.
You received’t find a way to carry out a web based scan and repair errors on the system drive (C:). When you run the
chkdsk C: / F / R command, you will note that the disk is locked and can solely be checked on the following Windows restart:
Cannot lock present drive. Chkdsk can't run as a result of the quantity is in use by one other course of. Would you want to schedule this quantity to be checked the following time the system restarts? (Y/N).
If you need to test the disk on the following boot, press
Enter. The message seems “This quantity will likely be checked the following time the system restarts”.
Now, in case you restart Windows, the disk test will begin. You want to wait till it ends.
If you need to test the drive for an error offline (skip on-line test), use the offlinescanandfix choice:
chkdsk E: /f /offlinescanandfix
When utilizing the offlinescanandfix choice for the system drive, you may be prompted to schedule a drive scan on the following reboot.
Offline disk test pace in Windows 10 has been considerably elevated in contrast to earlier OS variations.
/X is one other helpful chkdsk choice. It permits you to unmount a quantity earlier than checking it by forcibly closing all open file descriptors.
Also discover the brand new chkdsk choice –
/spotfix. This parameter is relevant solely to NTFS volumes. The spotfix parameter can considerably cut back the offline disk test time from hours to seconds. Instead of a full drive scan, it solely searches for and fixes errors beforehand recorded in the $corrupt file (populated throughout a traditional disk test). In this case, chkdsk instantly fixes errors with out losing time scanning the complete drive. This is very helpful when checking giant volumes.
It is just not really useful to cancel/interrupt the chkdsk command. However, in case you manually kill the chkdsk.exe course of, you received’t injury the quantity (it won’t be broken greater than it was initially). In any case, it is suggested to run a full disk scan after some time.
In Windows 10, disk upkeep (test and defragmentation) is carried out routinely on a schedule or when your pc is idle. You can discover data on the standing of automated disk test in Control Panel -> System and Security -> Security and Maintenance -> Drive standing. The screenshot reveals the drive state “
All drives are working correctly”.
You can discover the disk test activity (named ProactiveScan) , which runs as a part of Windows 10 Automatic Maintenance, in Task Scheduler -> Microsoft -> Windows -> Chkdsk.
Also, in fashionable Windows 10 builds, the storage diagnostics software StorDiag.exe (Storage Diagnostic Tool) has been added. This utility performs a number of disk test operations directly (
fltmc). The diagnostic log may be saved as an ETW hint. For instance:
stordiag.exe -collectEtw -checkfsconsistency -out %userprofilepercentdesktop
Checking Drive Errors with PowerShell
PowerShell four.zero launched a separate Repair-Volume disk test cmdlet. This cmdlet is the PowerShell alternative for the chkdsk command.
To carry out a web based test of the exhausting drive for errors from PowerShell, run the command:
Repair-Volume –driveletter C –scan
If you want to carry out an offline disk test and routinely repair errors, use the offlinescanandfix parameter:
Repair-Volume –driveletter E –offlinescanandfix
If no errors are discovered on the disk, you will note a
It additionally helps fast error fixing utilizing the spotfix parameter (solely errors discovered in the course of the on-line scan are mounted):
Repair-volume –driveletter E –spotfix
You can test a number of native drives directly:
Repair-Volume -DriveLetter EHI –SpotFix
The Repair-Volume cmdlet helps CIM classes that enable you to scan drives on distant computer systems:
Repair-Volume –driverletter c -scan –cimsession ny-fs01,ny-fs02,ny-dc01
Get-BodilyDisk | Sort Size | FT FriendlyName, Size, MediaType,SpindleSpeed, HealthStatus, OperationalStatus -AutoSize
View Check Disk (CHKDSK) Results in Windows 10
When you carry out a web based disk test, you may see full chkdsk statistics in the cli console. However, in case you scheduled a disk test with the offlinescanandfix choice, you received’t see the chkdsk abstract report on the Windows boot display screen. The Windows 10 boot display screen solely reveals the general share of the disk test accomplished.
In Windows 7 and earlier Windows variations the detailed details about chkdsk actions was displayed straight on the boot display screen.
In Windows 10 you may view the outcomes of the automated exhausting disk test solely in the Windows Event Viewer.
Open Windows Event Viewer by typing occasion in the search bar and choose Event Viewer utility (or by operating
In the following window, go to Windows Logs -> Application.
Right-click Application and choose the Find menu merchandise. In the search bar, sort chkdsk and click on Find subsequent.
You can search by the occasion supply. To seek for disk test occasions at Windows startup, you want to allow the filter by occasions from the Wininit supply. For user-initiated test disk occasions, see the Chkdsk supply.
The first discovered occasion with the Event ID 1001 and the supply Wininit has to be displayed. In the General tab, an in depth log with the outcomes of the latest disk test will likely be proven.

You can get data from test disk occasions utilizing PowerShell. The following command will export the 5 most up-to-date disk test outcomes from the occasion log and save them to the present desktop as a textual content file CHKDSK_SCANS.txt.
Get-EventLog -LogName Application -Source chkdsk | Select-Object -Last 5 -Property TimeGenerated,Message | Format-Table -Wrap| out-file "$env:userprofileDesktopCHKDSK_SCANS.txt"
This file may be opened in any textual content editor.
Thus, we obtained a disk test log carried out throughout Windows 10 startup.
