Since my PC is always on I need to minimize the powering on / off cycles of my hard drives. I have been able to do this for all except the plugable tray. The tray cycles my drives dozens of times per day. There is a direct relationship between the number of power cycles of a computer and the probability of failure of its drives. How can I force the drive to stop spinning down?
