WD Sentinel DX4000 Long filename support issue

When copying over 2TB of files from a Linux NAS box to my Sentinal I received an error on several thousand files that stated the file path names were too long and could not be copied. I need to get all the files transferred ASAP. This is a known issue on several later Windows platforms and there is supposed to be a hotfix for this. Can someone please advise where I can download this and how to install it on the Sentinal?

These folks suggest Robocopy

But your best bet is to shorten them as they will continue to cause problems

Thanks all for your responses.  Fastcopy seems to do the trick.   

Well, you can use long path tool as well.
