Question

I keep all my personal and business data on a 2TB Passport external drive and back up key parts of it daily to two other external drives using robocopy. I've been doing this for years.
Since I upgraded to Windows 10, however, I keep getting the error I mentioned above (in the subject line). Robocopy complains that some file or directory on the **destination** drive is unreadable, and sure enough, I am unable to delete the file. I've tried both File Assassin and File Unlocker. File Assassin complains that it cannot see the file. File Unlocker claims to delete it, but I still see it in Windows Explorer, even after rebooting. The only way to get rid of the file is to boot in safe mode and delete it.
Problem is: this keeps reoccurring in different places in the filesystem !!!
Relevant facts:
* It occurs on *both* of my backup drives, which suggests to my mind that the problem is not with the backup device.
* Again, it occurs with different files in different places. There's no detectable pattern as far as location.
* CHKDSK reports no problems on any of my disks
* SFC reports no problems on any of my filesystems
For now, I've settled on the following work-around: I tell robocopy to ignore read errors:
For EX: robocopy g:\data q:\data /mir /R:0 /W:0
So now robocopy runs to completion instead of hanging, but it reports FAILURES.
I am worried about my data and would appreciate guidance and suggestions.

Hi pluviosilla,
According to your description, do this issue occurs after you upgrade the 1607 version? If it could be work fine in Safe Mode, I suggest that we could try boot in Clean Boot to avoid the effects of third party software. We could try use the command chkdsk /f Drive to find and repair errors on drive. Also we could check the pemission on both the source and destination. Please refer to the link below.

Also we could check the command about the robocopy.
The /mir option is equivalent to the /e plus /purge options with one small difference in behavior:
With the /e plus /purge options, if the destination directory exists, the destination directory security settings are not overwritten.
With the /mir option, if the destination directory exists, the destination directory security settings are overwritten.

Considering the Anniversary Update is released recently, if the issue persists, you could try the built-in "Feedback" tool to submit the issue on your side.
Hope it will be helpful to you
