[Bug 595138] Re: Settings in /etc/hdparm.conf are not applied during boot

[Christoph Bier]

Thanks Bob for pointing me to this bug! On 2011-10-16 I filed a
duplicate of this bug: https://bugs.launchpad.net/bugs/875719. Apologise
for that. Here's a summary of my observation:

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. hdparm with -S set to 1 works, too. But the disks
spins up again after 15 seconds. I guess some process accessing the disk
prevents the disk to spin down which only occurs with -S set up high
enough. How can I detect which process prevents the disk from spinning
down? This hard disk is my backup disk and only in use every 4 hours by
a cron job.

Title:
  Settings in /etc/hdparm.conf are not applied during boot

Status in “hdparm” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: hdparm

  After upgrade to Lucid the hard drives never spindown. The hdparm
  spindown settings (and most likely others) in /etc/hdparm.conf are not
  being applied during boot.

  This seems to have happened after removing the init.d script.
