HDD's never hibernate

[N0Klu3]

So I'm using SABnzbd, Couch Potato, Sick Beard, Headphones, but noticed my HDD's never hibernate...

They used to hibernate when I never had the above packages installed, but now they seems to be always on.
Im not sure if there is a setting in each application or what, so maybe make it search like each day, or something to let the HDD's sleep.

Thoughts?

If you have SABnzbd scanning for NZB files, you can try to put the "Watched folder" to an USB disk (or stick).

Well this is not really an spksrc issue. If you run an app that uses your HDD it is likely to wake it up.

Either do not use those apps or disable hibernation.

So, SAB is not downloading anything atm, and CP/SB/Headphones are not searching for anything.
So why should my drives be spinning 100% of the time for no reason?
Regardless of if I use the app or not if its causing stress for no reason or shortening the life of something its an issue!

Why would logs or watched folder cause SAB to constantly run?
Can we not kill the watched folder if its not being used? or why are the logs being written to all the time?

What damages a HDD is Load Cycle Count and Start/Stop Count (see http://en.wikipedia.org/wiki/S.M.A.R.T. for details) not writing data to the disk.
Hibernation is good to save energy but not for the hard disk drive life. Hibernation may shorten life of your disks, not writing data to them.

There is no action that could be taken from our part to allow hibernation. You can tweak your settings so log folder is on an USB drive for example, maybe that'll help not waking up your drives
