I too have similar issues on a DNS-343.
The earliest issues were generated when, under a single user, Volume_1 would just disappear from the desktop and unmount itself. If this happened during a copy, then what ever file was being copied at the time would be undeleteable on Volume_1. I tried FTP, SMB, Rebooting everything, but the errors all was persist. File in use, not enough privileges etc etc. Almost without any rational cause folders copied to the NAS end up with either read/write, read only, or 'custom access'. If you look at these in terms of CHMOD most of the working files / folders are '777' and user / owner '501', but then there's more recent items that since introducing users and groups have ended up being '755' and user owner '502'. The later items aren't readable, you can see them, but can't open or copy them off or delete them and there's now way I know of to change this. We need to customize access for certain folders, but that aside, can I return to a single user and have full permissions across all this existing data??
Is there a way, without using Funplug to re-publish corrected permission through an entire share??
Also, if anyone has in insight in to why it seems to randomly appear and disappear from the 'Shared' section in MAC OS Finder's sidebar, that would be really helpful too! I think it may have something to do with FTP access.
