The problem can also occur in certain situations in windows too.

The problem is due to a feature called '''intellipark'''. Which parks the heads on the drive after 8secs of drive inactivity.

Many Linux installations write to the file system a few times a minute in the background (eg. writing logs). As a result, there may be 100 or more load cycles per hour, and the load cycle rating may be exceeded in less than a year. This problem also makes the drives very unresponsive and makes your system feel slow as the heads need to be unparked when you try and load something.

My friend has killed two 1TB Green drives on his XBMC media box in 4years.  The 500GB drive in my partners machine is in deep trouble as the '''load_cycle''' count is at '''1991353''' after a '''power_on_hours''' of '''29549hrs'''. Compare that to my WD Black 1TB which has a '''load_cycle''' count of '''721''' after '''13579hrs'''.

Now Western Digitals specsheet says that the drives are good for 300,000 Load/unload cycles, so this is a pretty big deal.

But we arn't going to use that. Instead we are going to use a Linux unnofficial alternative called '''idle3-tools'''. It is already packaged in Manjaro so no need to compile it. but here is the source [http://idle3-tools.sourceforge.net]

Now really we want to just disable the timer altogether like it is on a black drive, and just let our systems power management handle the drive.
