Repairing Disk Drives

In the old days, disk repair was performed by chkdsk.exe. This still works.

In Windows Server 2012 R2 and Windows 8.1, a new cmdlet called Repair-Volume was added. Like chkdsk.exe, it needs full Administrator privileges.

You can use it to scan drives for errors:

 
PS> Repair-Volume -Scan -DriveLetter c
NoErrorsFound

PS>
 

You can also use the cmdlet to fix errors:

-OfflineScanAndFix: Takes the volume offline to scan the volume and fix any errors found (equivalent to chkdsk /f).

-SpotFix: Takes the volume briefly offline and then fixes only issues that are logged in the $corrupt file (equivalent to chkdsk /spotfix).
