-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).
