When you are playing songs, your HD would not spin down at all. HD spin down time is defined by user in most operating systems. It is the duration that if there is no disk access at all that the disk will spin down. Most people would set this time between 15min to a couple of hours to make more sense. Say for example, if you set the time to 30min, the HD only spins down if there was no activity in the past 30 minutes. If you are using your computer or playing songs with your squeezebox, the HD will not spin down at all. However, when you stopped using your computer, or stopped squeezebox, your server will spin the HD down after 30min. It could be a huge energy save as for a lot of people they will only listen to music a couple of hours a day. In this scenario, your HD will only be powered up and down a couple of times a day and HD life would not be affected. On the other hand, there could be some spin down issues with notebook drives used in a server (which is a different problem). Notebook drives have firmware designed to spin down during short inactivity to save more power. In a server environment, depends on the OS, this could cause repeated load and unload cycle causing excessive wear. -- Honva Honva's Profile: http://forums.slimdevices.com/member.php?userid=14948 View this thread: http://forums.slimdevices.com/showthread.php?t=75902 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

I would assume HD firmware to be > optimized for power consumption when in idle. Spindown/spinup every 3 minutes will kill your drive in 6 months or something like that. As said earlier, spun down the drive draws something like 3 to 5W if it is reasonably green; then spinning up will consume probably over 15W, and reading 7 to 12W. Overall I suppose you'd save energy, as the spinup and reading phases are relatively short. But you're really going to break the drive. Besides, spinning up a drive takes some time, there is a chance skipping from the remote won't feel too fluid. -- epoch1970 Daily dose delivered by: 2 SB Classic (fw 130), 1 SB Boom (fw 50) SqueezeCenter 7.3.4 (Debian 5.0) with plugins: ContextMenu, SaverSwitcher by Peter Watkins Server Power Control by Gordon Harris WeatherTime by Martin Rehfeld IRBlaster by Gwendesign (Felix) FindArt, CDplayer by bpa BBC iPlayer, SwitchPlayer by Triode PowerSave by Jason Holtzapple TrackStat by Erland Isaksson. epoch1970's Profile: http://forums.slimdevices.com/member.php?userid=16711 View this thread: http://forums.slimdevices.com/showthread.php?t=75902 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
