Just moved the contents of various Mac formated harddrives on my new DS1522+. After the copy, there are a few folders, the contents of which are visible under DSM, but not through SMB (Finder) on my Mac. I tried connecting to SMB both with my normal NAS user account and my admin account.
I found this article, but couldn’t try it because I’m probably not typing in the path properly. This is it: smb://BUCKET._smb._tcp.local/Projects/2017 - Astro/E. Dist. Also tried: /Projects/2017 - Astro/E. Dist, with and without “”. There are many other similar folders that work normally.
