Public bug reported:
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.
