Title:
  Power Manager Default Settings for Battery, don't permit the hard
  drive to spin down

Status in hdparm package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: gnome-power-manager

  I discovered that the output of "hdparm -B /dev/sda", gives me a value
  of 128, which prevents the HD from spinning down.

  from hdparm man page  (notice the bit about 128 being in the range that
  prevents spinning down):

    -B       Query/set Advanced Power Management feature, if the  drive  sup‐
               ports  it.  A  low value means aggressive power management and a
               high value means better performance.   Possible  settings  range
               from  values  1 through 127 (which permit spin-down), and values
               128 through 254 (which do not permit  spin-down).   The  highest
               degree  of power management is attained with a setting of 1, and
               the highest I/O performance with a setting of 254.  A  value  of
               255 tells hdparm to disable Advanced Power Management altogether
               on the drive (not all drives support disabling it, but most do).

  We should change the value to 50 or so to allow for a decent hard
  drive spinning down value.
