This bug was fixed in the package hdparm - 9.27-2ubuntu1

---------------
hdparm (9.27-2ubuntu1) maverick; urgency=low

  * Merge from Debian unstable (LP: #516249); remaining changes:
    + debian/control:
      - Do not depend on lsb-base (we no longer use init script)
      - Add Homepage
      - Add Breaks on old udev
      - Bump debhelper depends for dh_installudev changes
      - Recommend powermgmt-base, so we can use on_ac_power to detect if we're
        on battery.
      - declare a Breaks: on pm-utils (<< 1.2.5-2ubuntu8), due to the change of
        the hdparm-functions API.
      - Replace pm-utils versions which shipped that script.
    + debian/hdparm.install:
      - Use hpdarm.udev instead of .rules
      - move hdparm-functions to /lib/hdparm.
    + debian/hpdarm.udev:
      - refactor to use the above functions instead of embedding a parser.
    + debian/hpdarm.dirs:
      - Drop unused /etc/udev/rules.d, add lib/udev for our udev-script
    + debian/rules, debian/hdparm.udev-script:
      - Install udev-script, drop init file stuff
      - Pass --priority=85 to dh_installudev
    + debian/hdparm.postinst: The transitional code to create
      /etc/udev/rules.d/z60_hdparm.rules also got wrongly executed on new
      installs, leaving a broken symlink behind. However, we do not need this
      in the first place, so just throw away the code completely.
    + debian/hdparm.preinst: Remove broken symlink on upgrade.
    + Add a new option to hdparm.conf, apm_battery, which is used in place of
      apm when we detect that we're on battery power.
    + debian/hdparm.udev-script, debian/hdparm.init:
      - only use the 'apm' setting when we're not on battery; when we are on
        battery, apply the separate 'apm_battery' setting.
      - Don't call hdparm -f for every drive; no clear rationale was ever given
        for doing this, and doing so slows down hard drive access at boot time.
      - also don't call sync...
    + debian/hdparm-functions:
      - break out a barebones parser for /etc/hdparm.conf and install it to
        /usr/lib/pm-utils, for use in /usr/lib/pm-utils/sleep.d/95hdparm-apm.
      - refactor so that it can be used by the udev script as well
      - drop handling of "command_line" here - we shouldn't be running this
        for every hard drive and every power event, this should be supported
        only by an init script (if at all)
      - Don't apply default APM policy to Firewire or USB devices when running
        from udev (LP: #515023, #548513).
      - Fetch ID_PATH from 'udevadm info' if it isn't already set in the
        environment (LP: #567182).
      - Factor Firewire/USB check out into a new hdparm_try_apm function.
    + Add debian/95hdparm-apm:
      - pm-utils script to adjust hard drive APM settings
        after resuming. This was previously shipped in pm-utils, but is more
        appropriate here (see /usr/share/doc/pm-utils/README.distributions).
      - Skip Firewire and USB devices.
