- Product
- OneDrive
- Device & OS
- not provided
- Scenario
- Attempting to delete, move, copy, or paste a file that is stuck syncing within the local OneDrive folder.
- Observed behavior
- The file cannot be altered and displays Error 0x80071129. Standard troubleshooting steps like resetting the OneDrive client do not resolve the issue.
Before attempting command-line fixes, ensure you have backed up any accessible important files from your local OneDrive folder and verified the drive letter where your OneDrive folder is installed.
Run CHKDSK Utility Using Command Prompt
Since Error 0x80071129 indicates file system corruption, running the Check Disk tool can locate and repair invalid reparse points.
The CHKDSK command scans your hard drive for logical and physical errors. Running it with specific parameters will allow Windows to automatically locate and repair the corrupted reparse point buffer causing the OneDrive sync loop.
Click the Windows Start button, type 'cmd' in the search bar, right-click on 'Command Prompt', and select 'Run as administrator'.
In the command prompt window, type `chkdsk C: /f /r` and press Enter. If your OneDrive folder is located on a different drive, replace 'C' with the correct drive letter.
You will likely see a message stating the drive is in use. Type 'Y' and press Enter to schedule the disk check for the next time your computer restarts.
Restart your computer. Allow the disk check to run to completion before Windows boots up. Once logged in, attempt to delete or move the problematic OneDrive file.

Clear the Microsoft Office Document Cache
Sometimes stuck OneDrive files are linked to corrupt Office document cache files. Clearing this cache can free up the stuck sync process.

Frequently Asked Questions
What does 'the tag present in the reparse point buffer is invalid' mean?
This error usually indicates that the metadata or file system information linking a file to its cloud counterpart in OneDrive has become corrupted on your hard drive, preventing Windows from reading or modifying it.
Will resetting OneDrive fix Error 0x80071129?
In most cases involving this specific error, resetting the OneDrive client does not work because the issue lies in local file system corruption rather than an application glitch. Running the CHKDSK command is the recommended fix.
Can I run CHKDSK on an external drive with OneDrive files?
Yes, simply replace 'C:' in the `chkdsk C: /f /r` command with the drive letter of your external drive (for example, `chkdsk D: /f /r`). You won't need to restart your computer if the external drive is not your primary system boot drive.
