Ok. So if I then list, for example, the directory shown below on the Seagate drive, it gives me this (just a couple of files shown) :-
ls -l /media/Seagate\ Backup\ Plus\ Drive/Epox_Share/Drive_C/Library/ total 12465 -rw------- 1 chris cdrom 936885 Feb 28 16:08 5_Fonts.zip -rw------- 1 chris cdrom 23552 Feb 28 16:08 aefdisk.zip

But dredging the memory banks, if I type 'groups' I get this :- cdrom wheel usb cdwriter users vboxusers
So looking at what groups are shown for the Seagate Library folder, it seems I *am* a member of the cdrom group so why can't I write the files/create directories etc on the NAS?
Simple, because they haven't got the group write (or any other) permission set.
In the -rw------- flags you see before the file names the first - indicates various odd flags, then there are three groups of three which can be set to r, w, and x for read, write and execute permission respectively. The first three are for Owner, the next three are for Group and the last three are for Anyone/world. So on the above files you have only Read and Write permission for the owner. The files have group cdrom but no permissions for that group.
