SyncToy misses files when replicating from NAS to C:

  I had a problem recently when replicating a new folder created on my T: drive (a NAS which is the RHS of sync-pair) to the C: drive (the LHS).

  Of 168 files, only 165 were copied.  Missed files included one .html and 2 .png

  Once the files are missed, then SyncToy continues to miss them.  I tried manually copying the three files to the C: drive, but this resulted in a SyncToy error for each file to say that it couldn't be created on the NAS.  I found that overwriting the three missed files on the NAS with identical copies resolved the problem however.
  

  I've run several tests to see if this is repeatable - and it frequently happens, but not always the same files are involved.  Replicating from C: to NAS always seems to work, but not NAS to C:  I upgraded the driver in the NAS but this made no difference.

  The files involved were auto-generated for a website and the ones that were missed have identical timestamps to their neighbours (listed by name).

  Any ideas?

  - Obviously I can keep on comparing file counts, working out which files are missed and manually resolving the difference, but this kind of negates the point of using a utility!
