Administers and monitors NTFS self-healing repair operations.

For examples of how to use this command, see Examples.

Syntax

fsutil repair [initiate] <VolumePath> <FileReference>
fsutil repair [query] <VolumePath>
fsutil repair [set] <VolumePath> <Flags>
fsutil repair [wait][<WaitType>] <VolumePath>

Parameters

Parameter Description

initiate

Initiates NTFS self-healing.

<VolumePath>

Specifies the volume as the drive name followed by a colon.

<FileReference>

Specifies the NTFS volume-specific file ID (file reference number). The file reference includes the segment number of the file.

query

Queries the self-healing state of the NTFS volume.

set

Sets the self-healing state of the volume.

<Flags>

Specifies the repair method to be used when setting the self-healing state of the volume.

The Flags parameter can be set to three values:

  • 0x01: Enables general repair.

  • 0x09: Warns about potential data loss without repair.

  • 0x00: Disables NTFS self-healing repair operations.

wait

Waits for repair(s) to complete. If NTFS has detected a problem on a volume on which it is performing repairs, this option allows the system to wait until the repair is complete before it runs any pending scripts.

[WaitType {0|1}]

Indicates whether to wait for the current repair to complete or to wait for all repairs to complete. WaitType can be set to the following values:

  • 0: Waits for all repairs to complete. (default value)

  • 1: Waits for the current repair to complete.

Remarks

  • Self-healing NTFS attempts to correct corruptions of the NTFS file system online, without requiring Chkdsk.exe to be run. This feature was introduced in Windows Server 2008. For more information, see Self Healing NTFS.

Examples

To enable self-healing repair on drive C, type:

fsutil repair set c: 1
