I am a Linux newbie. How do I do what you asked? The question is moot for me. While waiting for more than a month for a response to my bug report, I have already found a workaround. I reformatted the drive from NTFS to ext4. This solved the problem for me but I lost the capability of a Windows machine reading my data. Given that Windows 10 installer will not re-install windows on a large drive this is not an issue with me. I have written off Windows as a bad deal with no support.
However others may want to keep compatibility with Windows. In that case the bug in the NTFS driver needs to be fixed.

Status in linux package in Ubuntu: Confirmed Bug description: I am trying to recover data from an HFS+ files system on a 4TB external USB 3 drive. Copying 3TB from the 4TB HFS+ drive to a 4TB NTFS drive using MATE Terminal cp -anR from to took 2 days. When I try to copy the same data to a 6TB NTFS USB 3 drive the results are glacial. 750GB has taken over 6 days. Obviously there is a problem of scale drive in Ubuntu MATE. I invite the developers to plug in a 12TB drive and see just how glacial (no - not glacial, more on the order of plate techtonics) slow their design is.
