Robocopy hangs, dependant on working directory

Hi lb483,



Welcome to Microsoft Community. I'm Mosken, let me help you.



According to your description, I knew that there is no log files as you would expect when you copy files with Robocopy, even if you have included the /log parameter. Is that right?



Generally, running Command Prompt requires basic permissions, you can successfully copy the file that means you have sufficient permissions to access (read, write, modify) the source and destination locations and their data, but I still suggest you try run the Command Prompt as an administrator and then Execute the command again.



Then I suggest you redirect the log file to a directory other than the source and destination when you use /log parameter, such as a non-root directory on a non-system partition or the desktop.



You can visit robocopy | Microsoft Docs to get more detailed information about Robocopy, hope it will help you.

The above steps are provided based on the information I have learned so far, and hope that could help you a little. If the problem still exists, please provide us a full PSR from the beginning, through the whole process, and until the error message is displayed, so we can further investigate.



Best Regards,

Robocopy speed question

I have 2 large files (total 210 GB) being copied by Robocopy between 2 external drives. Task Manager under "Disk" indicates a transfer speed of 30 MB/s.

A straightforward calculation indicates that it should take 117 minutes to complete the transfer. In practice, however, I am noticing a time to completion of about 250 minutes, or more than double the theoretical calculation.

Can anyone please explain this large discrepancy or, alternatively, suggest some way to improve on this performance? With Robocopy I use switches /mir /xo /mt:80.

All suggestions appreciated.
