» Dear Dennis,

Thanks for your article on how to reset admin password on a Seagate NAS (network attached storage) — this was the only article I could find on the subject. I have a related question. I’ve done a full reset of the NAS (wiping out all data) and recreated my network shares, and now I’m ready to copy data back. In the past, I’ve used Windows file copy to do this, but sometimes it fails and then I have to start over again. I did research on this subject and it’s my understanding robocopy is a much more reliable method and will actually resume the transfer if interrupted. The problem is that every time I try to copy the data back to the NAS, I keep getting an error ‘ERROR 5 (0x00000005) Changing File Attributes’. I can’t seem to find the answer to this and require your expertise. Can you please help? «

My response:

I asked Gerry if he would like me to connect to his machine using
my remote desktop support service in order to have a closer look, and he agreed.

Below I will discuss my findings.

How to Fix: NAS, Robocopy ERROR 5 (0x00000005) Changing File Attributes

After some research, it appears that when robocopy copies files, it will (by
default) attempt to store file attributes in addition to the data and time
stamps on the destination media.

Since a NAS is essentially a mini Linux machine (box) with hard drives attached to it, attempting to modify file attributes will result in an error because Linux is in control of the storage and only permits limited changes to files — even while copying a file.

Therefore, the way to get around this problem is to not to copy the file attributes using robocopy’s command line arguments.

For example, the following command would work:

robocopy e:temp s: /e /copy:DT /w:1 /r:1 /v /log:»c:temprobocopy_copy_back_to_nas.txt»

This assumes the e:temp is the source directory and s: is the destination (NAS). The
/copy:DT switch tells robocopy to copy the data and time stamps (but
not the file attributes), while /w:1 and r:/1 says to only retry a maximum of 1 times if there is an error in the file copy, with 1 second intervals between retries. The /log:»c:temprobocopy_copy_back_to_nas.txt» line means to make a log of the file copy and save it to c:temprobocopy_copy_back_to_nas.txt, while the /v switch means to log verbose errors such as skipped files or files with errors.

How to View Robocopy Log Output (Powershell)

If you want to view the log while it’s copying, open up a powershell command prompt and run the following script:

Get-Content c:temprobocopy_copy_back_to_nas.txt -tail 1 -wait

This will provide you with a window of activity (with 1 second intervals) to
see the progress. In Gerry’s case it took over a week to copy the data back onto
the NAS, so this was incredibly useful — plus he can parse the log file for
errors if needed, described next.

How to View Robocopy Log for Errors

To scan the above log file for the word «error», you could use the following
syntax via the command line (with limitations):

type c:temprobocopy_copy_back_to_nas.txt |findstr -i error >c:temprobocopy_error_log.txt

This will output any error messages to c:temprobocopy_error_log.txt —
however you may need to open the log to find the exact reason for the error.
Frankly speaking that might be irrelevant because if the file won’t copy, it
likely won’t ever copy (due to a media error, for example). That said, it’s
worth looking at a few errors to see if the error messages are all the same. In
that case there could be a problem with the source or possibly the robocopy
arguments.

If you want a much more robust way

to extract robocopy errors from the log, consider using this powershell command
script as discussed on this page.

How to Log Robocopy Errors Only

If you only want to log only errors from robocopy regardless of the error reason, you can use this method:

robocopy [source] [destination] /copy:DT /w:1 /r:1 /nfl /ndl /njh /njs /ns /nc /np >> log.txt

I hope that helps.
