God knows, I've just not given it much study.  As I said, before smartd, 
all I ever cared about was errors.

BTW, just now I wondering what the relationship is between


# default is every 30 minutes:
#smartd_opts="--interval=1800"

in '/etc/default/smartmontools'

and the '-i' switch used in '/etc/smartd.conf'.  The latter seems to 
have a different unit but in 'man smartd.conf' the switch is mentioned 
only in the text, it does not have a section devoted to it.  It seems 
legal to use but I'm not sure what's going on there and the value can't 
be above 255, it seems.

And:

I've tried '-n standby' but it seems to be ignored, all my disks spin up 
after '$ smartd -q onecheck' even if I had just spun them down:

$ hdparm -S60y /dev/sda; hdparm -S60y /dev/sdb; hdparm -S60y /dev/sdc

/dev/sda:
  setting standby to 60 (5 minutes)
  issuing standby command

/dev/sdb:
  setting standby to 60 (5 minutes)
  issuing standby command

/dev/sdc:
  setting standby to 60 (5 minutes)
  issuing standby command

$ smartd -q onecheck
...

$ hdparm -C /dev/sda; hdparm -C /dev/sdb; hdparm -C /dev/sdc

/dev/sda:
  drive state is:  active/idle

/dev/sdb:
  drive state is:  active/idle

/dev/sdc:
  drive state is:  active/idle
