Description

The Repair-Volume cmdlet performs repairs on a volume. The following repair actions are available:

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

Scan: Scans the volume without attempting to repair it; all detected corruptions are added to the $corrupt system file (equivalent to chkdsk /scan).

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

Examples

EXAMPLE 1

PS C:\>Repair-Volume -DriveLetter H -Scan

This example scans the volume H: and reports errors only. It uses the -DriveLetter switch to designate the volume by its drive letter and -Scan to indicate the scanning action.

EXAMPLE 2

PS C:\>Repair-Volume -DriveLetter GHI -SpotFix

This example uses the spot verifier functionality to quickly fix volumes designation G:, H: and I:. It uses the -DriveLetter switch to designate multiple volumes by their drive letters and SpotFix to indicate the quick fixing action.

EXAMPLE 3

PS C:\> Get-Volume

PS C:\> Repair-Volume -FileSystemLabel "System Reserved" -OfflineScanAndFix

This example takes the System Reserved volume offline, and fixes all issues. This volume has no drive letters assigned to it. The first command, Get-Volume gives an overview of the volumes on the local computer. As the output indicates, the volume bearing the "System Reserved" label has no drive letters. Next, the Repair-Volume cmdlet uses the -FileSystemLabel switch to designate the "System Reserved" volume and the -OfflineScanAndFix switch indicates the volume should be taken offline and scanned in full.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Type:CimSession[]
Aliases:Session
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-Confirm

Prompts you for confirmation before running the cmdlet.

Specifies a letter used to identify a drive or volume in the system.

Type:Char[]
Position:0
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-FileSystemLabel

Specifies the volume to scan based on the file system label (the volume name).

Type:String[]
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-InputObject

Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.

Type:CimInstance[]
Position:Named
Default value:None
Accept pipeline input:True (ByValue)
Accept wildcard characters:False
