[Bug 875719] Re: hdparm does not spin down hard disk on inactivity timeout

[Bob Harvey]

I have upgraded to 12.04LTS server and that does not respect
/etc/hdparm.conf either.

My hdparm.conf file looks like this:
------------------------------------------------------
bob at server01:~$ cat /etc/hdparm.conf
/dev/sda{
        spindown_time = 30
        write_cache = off
        sleep
        }
/dev/sdb{
        spindown_time = 30
        write_cache = off
        sleep
        }
/dev/sdc{
        spindown_time = 30
        write_cache = off
        sleep
        }
/dev/sdd{
        spindown_time = 30
        write_cache = off
        sleep
        }

------------------------------

After a reboot my disks are active.

If I issue 
sudo hdparm -Y /dev/sd{a..d}  
then they go into standby.


Is there a log file that can confirm hdparm is being accessed at all?

Title:
  hdparm does not spin down hard disk on inactivity timeout

Status in “hdparm” package in Ubuntu:
  Confirmed

Bug description:
  First off, I'd like to mention that hdparm -S worked with 10.10. But
  with 11.04 my external hard disk (Seagate) connected via eSATA
  ExpressCard on a ThinkPad X200s doesn't spin down anymore on
  inactivity timeout set to 12 (1 minute). I'm still able to spin down
  the disk with the -y option---but a few seconds later it spins up
  again. This hard disk is my backup disk and only in use every 4 hours
  by a cron job.
