synctoy is a great tool
when it syncs it creates a log on both sides that
lists the files and folders it manuevered. without these logs then
the synctoy has no guidance "persay" as to what
has been moved, when, size, etc.... and more especially
the sync direction whether it was from a to b, or b to a, or
some a to b, etc...
further, it works best with ordinary files, docs, pics
and does not work for system files.
system files are best copied via disk images.
what has happened to me is that if there is one file that cannot be accessed
by the synctoy, synctoy will be disrupted and stop
syncing all of the files in the batch.
It looks like that your synctoy copied all the folders successfully,
but there was 1 file that was un-copiable afterwards.
If you re initiate a snyc you will see the file name that it gets stuck on.
Afterwards you would have to manually
move that particular file or files out of the folder. I think in my case
they were not needed and i deleted them anyways - they were rogue
files inside my doc folders.
if your main drive crashed, a repair can restore the
o.s., the booting, etc and will not disturbe your
other softwares, files, pics, etc....
possibly you can log in recovery console and
get your vital files moved onto a reliable media before
attempting a major restoration..
