OneDrive bug: The tag present in the reparse point buffer is invalid.

Question

I'm trying to "robocopy /MIR source target" to update a folder within my OneDrive for business folder and I'm getting this strange error:

2021/02/24 16:04:10 ERROR 4393 (0x00001129) Accessing Destination Directory C:\Users\lovet\OneDrive - L***** ********\Finances\paystubs\2020\

The tag present in the reparse point buffer is invalid.

Hi Chris,

The message: "The tag present in the reparse point buffer is invalid" indicates that some of those junction files are likely in a damaged state, this could happen if OneDrive had crashed or terminated improperly at some point.

Usually this can be fixed by following these steps:

1. Open command Prompt as an Administrator
2. Type in chkdsk c: /r /f
3. When command prompt asks to answer Y/N, answer Y and allow disk check. (Note: If your system drive is different, then replace it with your drive letter e.g. put a d: instead of a c:)
4. Restart PC, allow the disk check to run. Log back into your PC and then delete the folder or file.

If it did not work for you, try rebooting into safe mode (hold shift and click on restart).

Best regards,

This solution worked perfectly for me; thank you. I didn't have to reboot into safe mode. I just pressed the Windows key, typed "cmd", right-clicked on the Command Prompt icon and clicked "Run as Administrator", typed in the command "chkdsk c: /r /f", rebooted my computer, and waited for 10 minutes while the disk scan completed. Upon rebooting, everything was fixed. 

For what it's worth, this is the *only* solution from answers.microsoft.com which has ever worked for me.

Answer 3

This has become a daily issue for our business - it started about 2 months ago - has Microsoft made any changes to the OneDrive app? Is it now running as a 64-bit or 32-bit agent? The chkdsk fix works when it happens, but it is a nuisance - especially since we don't have this issue with other cloud storage providers. Any thoughts on how to prevent this from happening?

Thanks,

Jack

Answer 4

chdsk doesn't do anything for me. I still have folders that can't be deleted because of this reparse error.

Following the steps in this answer worked perfectly. Be ready to spend a little time letting the computer do its thing, but the results are worth the wait (for me, approx. 20 min)
