I'm looking for a way to schedule when an external hard drive connected to my Linux (Debian 9) box goes to sleep (stops spinning).
To put this into content: I have a Linux box that runs as a multimedia server. If a call is made to fetch content that is on the external hard drive, it often takes 15-30 seconds for the hard drive to wake and start spinning which a) is frustrating and b) sometimes causes timeouts with the multimedia server. I could set the hard drive to be awake and spinning 24/7, but this seems a waste when most of the time I only use the multimedia server when I'm at home.
Is there any software tool or command I could use to set a weekly schedule for when the hard drive is spinning - e.g.
Monday-Friday: SPINNING between 5pm and 11pm
Saturday-Sunday: SPINNING between 3pm and 11pm
OTHERWISE SPINNING on demand and sleep as per system timer
linux debian cron hard-disk

So you are decreasing disk run time, but starting/stopping your disk -40 times a week. Starting/stopping a disk is not without its costs. Unless electricity is very expensive where you are, it might not be worth the effort.

@waltinator Modern HDDs are designed to handle hundreds of thousands of start-stop cycles, so having one cycle per day is absolutely not harmful. It will literally take a thousand years to kill the HDD from excessive number of spin-downs at this rate. If anything, I would be more concerned about hours of useless spinning.

@waltinator Fair argument, but the whole point is that this would actually result in a net DECREASE in spin ups/downs, as at the moment it spins up and down more or less every time content is requested from the multimedia server, particularly during the times I want scheduling. As you say, it probably costs more energy every time the drive spins up - so leaving it spinning in the evenings would probably level off energy use.
