sudo hdparm -C /dev/sdb1:
/dev/sdb1:
drive state is: unknown
sudo hdparm -B 255 /dev/sdb1: (execute after HDD wake up since previous command
show result together with wake up process)
/dev/sdb1:
setting Advanced Power Management level to disabled
HDIO_DRIVE_CMD failed: Invalid argument
APM_level = off
