No more automatic standby with new controller

    after switching to a new controller card, the attached disk is not set into standby mode anymore as configured in /etc/hdparm.conf.

    I recently installed a Delock 89143 PCI Express to SATA II x2 and PATA Host Controller ( that is based on a JMicron JMB363 chip. Currently, there is only a single IDE disk drive connected to the controller. That drive is a Samsung SP1614N.

    The PC is running Debian Etch with kernel 2.6.18 and hdparm 6.9. Due to an entry in /etc/hdparm.conf 'hdparm -S 60 /dev/hde', the drive should enter standby mode after 5 minutes of inactivity.

    This setup worked flawlessly while the drive was connected to a Promise Ultra133 TX2. Since I replaced that controller by the Delock 89143, the drive does not automatically enter standby mode anymore. Instead, it stays in mode inactive/idle.

    Executing 'hdparm -y /dev/hde' by hand successfully puts the drive into standby mode.

    Any ideas what might be going on? Could it be that the drive's inactivity is not detected anymore?

    Thanks in advance, Malte

      Just for the record: The new controller had assigned the disk to a
      different device, /dev/hde instead of /dev/hdg. I updated various places
      accordingly, but forgot about /etc/default/hddtemp. So the hddtemp
      daemon prevented the disk from ever falling asleep. Stupid me.
