Ok, it's weird that the same problem has popped up again - I'm going to
guess it's the Synology NAS that is doing something strange here. Can
you clarify 'replacing the disks'? As in, you've just completely
replaced all the drives in the NAS and rebuilt the array and copied all
your data fresh from Cerce?

I can't exactly follow what you've done here but it's subtly wrong:

> julian@Cerce sudo chmod 777 Finances
> julian@Cerce sudo chown -R julian:julian Finances
> julian@Cerce sudo cp -avr Finances ~/Desktop/
> julian@Cerce cd ~/Desktop/Finances
> julian@Cerce ls -alh

Make the copy *first* before you start nuking perms/owns!

sudo cp -avr Finances ~/Desktop/

Operate on the new copy leaving the originals intact:

cd ~/Desktop
sudo chmod -R 777 Finances
sudo chown -R julian:julian Finances
ls -alh Finances

You missed the recursive flag on the chmod command by the looks of it.
Also check your original Finance folder because if you copied that
command sequence verbatim from your terminal session you've accidentally
slightly clobbered it...

I really don't recommend 'fixing' things with brute force like this
though, although we all do it sometimes of course *cough*

If you have just fully repopulated your NAS and are going from scratch
with a fresh set of data, it would definitely be worth getting to the
bottom of this properly whilst you've got the chance.

Cheers

PS: Also, as far as I can tell the "intr" options in your fstab have
long since been deprecated so should be removed. Your fstab entries do
look considerably saner than before though.
