File Date Attribute Problems

[OhioYJ]

So sometimes I have issues with my PC wanting to re-copy terabytes of data for no apparent reason.  Sometimes this command (including the /TIMFIX) prevents the problem, sometimes it does not.

 

robocopy "Q:\Videos" "Z:\Videos" /E /PURGE /R:2 /W:2 /TIMFIX /XF desktop.ini

 

Q: being located in my Desktop, Z: being my NAS. So right now it's copying files again, claiming they are "new files" when they aren't and they are already on the NAS, so I had a look in a folder it hadn't reached yet. It appears just the dates are different (NAS on the left, my PC on the right, everything else was the same). I'm sort of thinking the fix maybe to change the dates on my PC to the same, as it doesn't make sense that this file was created after it was modified?

 

 

Could I be missing anything else?

So I ended up using NirSoft BulkFileChanger to change the file attributes at once so the Created, Modified, and Accessed dates matched and that seems to have solved the issue?

 

I'm wondering if the created date is different (later) due to it being moved around to newer hard drives as I upgraded to larger ones.
