データ用HDがうるさいので使わないときはSpindownさせたい！
先日の方法だと毎回コマンド打たないといけないので、
dhparm.confに設定
ファイルを開けてみたら丁寧に説明があり、下記を最後に追加して
うまく行きました。1分でSpindownします。
/dev/sdb {
spindown_time = 12
}

gWakeOnLan
wakes up your machines using Wake on LAN
gWakeOnLan is a GTK+ utility to awake turned off computers through the Wake
on LAN feature.
The machines to turn on need to be shut off with the Wake on LAN magic packet
enabled.
Synapticからインストールして、Hose NameとMACアドレスを設定する。
起動するPC側ではBIOSでWakeOnLanを有効に設定する。
BOOTもスリープからの復帰もできました。

hard disk drive power spin down time setting?
Hdparm should work for any drive, You would use the command:
sudo hdparm -S 12 /dev/sdb
from: man hdparm
-S Set the standby (spindown) timeout for the drive. This value is
used by the drive to determine how long to wait (with no disk
activity) before turning off the spindle motor to save power.
Under such circumstances, the drive may take as long as 30 sec‐
onds to respond to a subsequent disk access, though most drives
are much quicker. The encoding of the timeout value is somewhat
peculiar. A value of zero means "timeouts are disabled": the
device will not automatically enter standby mode. Values from 1
to 240 specify multiples of 5 seconds, yielding timeouts from 5
seconds to 20 minutes. Values from 241 to 251 specify from 1 to
11 units of 30 minutes, yielding timeouts from 30 minutes to 5.5
hours. A value of 252 signifies a timeout of 21 minutes. A
value of 253 sets a vendor-defined timeout period between 8 and
12 hours, and the value 254 is reserved. 255 is interpreted as
21 minutes plus 15 seconds. Note that some older drives may
have very different interpretations of these values.
