How to put your USB-HDD to sleep
I am using an 1 tb HDD on my ATV as a backup medium for all our computers and I was wondering why it wasn't going to sleep.
However, HDDs need sleep just as humans do. Otherwise the die of heatstroke or something ;-) ...
- ssh enabled (http://code.google.com/p/atvusb-creator/)
- usb enabled (Enable_USB_Storage_on_2.x)
- firmware auto-update disabled (Take_2_Full_Update#12.29_Disable_Updates)
Set up power-management for the ATV
1. start the terminal.app and enter
mac$ ssh email@example.com
2. the AppleTV will respond and you should be able to logon with frontrow's password which is... frontrow
Welcome to the AppleTV (via atv-usbcreator) firstname.lastname@example.org's password:
3. you simply need to edit a .plist-file in the preference-folder
atv$ sudo nano /library/preferences/systemconfiguration/com.apple.PowerManagement.plist
You will be promted for the frontrow-password once more.
4. change the line after
<key>Disk Sleep Timer</key>
where x is the idle-time in minutes after the HDDs will get spinned down (i.e. 10).
3. save the file with <ctrl>-o , <enter> and exit nano with <ctrl>-x
4. exit the ssh-session
and 5. exit the Terminal
