Peter, thanks
well, the NAS box has 'smart' in its web admin config
but I'm not sure how much access I get to it
when I first got it, I enabled daily or weekly smart test
all the tests were 100%
I then disabled the daily test as I wanted to see if that was the spike in
my cacti cpu graph
then one hard drive simply dissapeared
but according to ps ax, smartd is running
I still haven't pulled the NAS down, I can log to the web admin, and,
everything is supposedly OK; under "HDD SMART":
----------------------------------------
Monitor hard disk health, temperature, and usage status by the hard disk
S.M.A.R.T. mechanism.
Select Hard Disk [3]

Hard disk does not exist.

hmmmmm, above is what I *see*
but, when I copy/paste, it also has:
======================================
Loading data, please wait...
This is an error message!!!

======================================
hmmm, is this the error message that I'm supposed to see ?
it doesn't show in FF/Chrome/IE
in ssg I get:
