I’ve set my internal storage HDD to go into standby after 10 minutes via the Drive Settings in the Disks application (it’s supposed to turn off whenever I’m not accessing music/videos/ebooks/etc.). This has always worked well until a week or two ago (I don’t recall changing or installing anything particular around that time that would cause problems). I can still put the HDD into standby manually (Standby Now in Disks), but it does not do so automatically anymore, and I’m not sure why. My assumption has been that some process is accessing the hard drive and preventing it from turning off, but when I turn it off manually, it doesn’t just randomly turn back on either, so I’m not sure.
Has anyone had this issue before? Is there a way to check for processes keeping a drive from shutting down?
