NTFS file permissions

OK, solved my own problem with the help of an older post I located. But first I did enable root SSH and snoop around.

For the directories I had problems with, the permissions were drwxr-xr-x root root. Similar for files. Pretty much what you would expect given the problem -- no write access for anyone but the owner.

So here's the fix: Don't use nobody and nogroup when resetting permissions. In the other post, root and root were suggested, and that's what I used. But I suspect any valid user name and group will work. Perhaps nobody and nogroup are set up as the defaults so that if you accidently hit Apply without specifying a valid user and group, nothing happens. Or maybe somethng broke in a recent firmware update. Whatever the case, open access to the files and folders was restored using this method. Through SSH, I have confirmed that all directory permissions are now drwxrwxrwx root root and files are similar.
