=46or Desktop HDDs, I don't think you should set the Power Management featu=
res.
AFAIK, HDDs (Especially the Desktop HDDs), have a life cycle. It is the Loa=

Cycle Count value which defines the life of your Hard Drive.
The more you park your disk, the more the Load Cycle Count increases.

This feature is found mostly in laptop drives, where it makes more sense.
