HD spin down delay

Is there a way to control after how long time without activity should the HD spin down in the TC?
I find it too quick. It is around 5 minutes for me (however did not measure exactly).
It just happens too often to me during normal operation and I have to wait 10-15 seconds at virtually each access of the drive.
Virtually each means that I do something on the computer like organizing my stuff, opening a file, study it, save it back after changes, and it is in the frequency longer than the spin down delay which feels the system became unresponsive.
I'd like to have such a control on the power saving interval.
I watched one movie from the TC and at some intervals it started to struggle with the playback which did not happen before when I was playing a movie from the shared drive of an other computer instead of the TC (where the network was a slower one!). I just hope the phenomenon is not because of the too frequent power saving intervals.

Does anyone know any progress for this problem since March?
I'm also checking in on this. Any new developments?
This has bugged me since the day we got ours (on launch day)
So far the T.C. makes for a terrible network drive. And we bought it based on the product description:
{quote:title=Apple wrote:}"But that doesn’t mean Tiger, Windows XP, and Windows Vista users can’t enjoy the benefits of Time Capsule, too. Because it mounts as a wireless hard drive, Tiger and Windows users simply access Time Capsule directly from the wireless network for exchanging and storing files quickly and easily."{quote}
Quickly? No.

  • TM drive spinning up delays system

    Hi,
    could not find the topic. please feel free to point me to a thread.
    I have a 1GB external HD as my TM drive. In Leopard it came to live only when accessing or writing backups.
    Now it spins up randomly, delaying the whole system.
    i.e.
    - when pressing on a link in Safari --> Beach ball until drive is up --> link opens
    - while writing this post --> it just started when pressing enter for this line (coincidence!)
    There are more occasions, but I do not remember when.
    Maybe its a Problem with safari?
    I do not see a reason for the TM HD to spin up?!
    Delay does not exist when in battery setting HD spin down is disabled.
    Maybe you have a suggestion?
    Maybe you could point me to a description how I can see what caused the read command?
    Thanks in advance

    Thanks for reply!
    Yes 1TB, thanks for pointing out. its a Seagate Desktop USB drive.
    I also noticed, when saving something it will spin up. I belief thats normal, because SL needs to know where to save. But I would think Apple is smart enough to implement a feature that SL knows if a HD is a TM only drive, therefore will only access it when read or write a backup. But maybe not.
    any other idea?

  • Hard disk spin-down

    I have installed a second hard drive (500GB Western Digital SATA SE16) in my Mac Pro quad-core. The drive spins down regardless of the power management settings (system preferences) and does so even when I’m actively working, but not directly accessing the second drive. It then spins up, with a corresponding time lag of 10-20 seconds and the spinning beach ball, when drive access is necessary. I know from the WD website that there is a setting for a jumper on pins 3 & 4 which will prevent spin down (much like would be required for a RAID setup). Does it make sense to enable that jumper to prevent spin down in this case? Will the system power management settings still function properly with the jumper set? Thanks for any input.

    Hi Pascal,
    "I'd really love to be able to work in silence.. and also save my poor hard disk !"
    As you already know, constantly spinning up and down is very bad for a hard disk.
    The best would be to have it sleeping all the time, but if this is not possible, better leave it spinning constantly then.
    "What is the annoying Panther feature (that Jaguar or OS9 didn't have) that keeps spinning my disk ?"
    I'm not sure about that, but I think it has to do with the constant rewriting of files that Mac OS X uses (causing defragmentation as a side-effect, BTW).
    My guess is that this didn't happen to your newly installed system, but now happens because there is much more fragmented free space on your hard drive.
    Another explanation is if the OS X behaviour mentioned has been enhanced after 10.3.6 or so?
    Or this can be also the kind of buggy behaviour described here:
    http://discussions.apple.com/thread.jspa?messageID=1267183#1267183
    The default spindown time if you choose "Put the hard disk(s) to sleep when possible" in Energy Saver, is 10 minutes of inactivity.
    You can use Cocktail or TinkerTool System to modify this 10 minutes delay, or paste this Terminal command:
    sudo pmset -a spindown 2
    to reduce the required inactivity to 2 minutes
    (but again, this is not what you are looking for, as this is worse than leaving it constantly spinning, unless perfect silence is so important to you).
    I don't know how to tell Mac OS X to behave like former systems though, and I don't even know if it is possible at all.
    Usually someone would like to set a longer spindown delay, like
    sudo pmset -a spindown 120
    for example.
    Good luck!

  • Disk re-starts after spin-down

    Hi,
    After a recent -Syu, my unused spare disk re-starts after it is stopped in /etc/rc.local by /usr/bin/sdparm -C stop /dev/sda. The upgrade included udev, initscripts, klibc-udev and yslog-ng. If I do /usr/bin/sdparm -C stop /dev/sda again in a terminal, the disk stops and starts again, running unnecessarily.
    Any ideas please?
    My thanks in advance.

    OK, I tried using hdparm -Y but I still have the same problem, in fact the disk starts even sooner, right after it starts spin-down! (with sdparm it starts after it completely stops spinning). I have tried hdparm -S 1 but there was no effect. I don't know if it will spin-down after a longer delay than the 5 sec specified though.

  • Internal Hard Disk spin down - Mac locks up

    Hi.
    Recently my iMac has started to occasionally lock up. The other evening it was quiet and I heard the hard drive spin down. Following this any action results in the beach ball, and eventually everything locks up, because it cannot read from or write to the disk.
    I have tried disabling hard drive sleep. Reseting the SMC and PRAM.
    Not sure if it is related, but I also noticed that the system profiler reports that the last hardware test was run in 4008 (I'm sure it used to say 2008). So I ran a hardware test, no problems. The last hardware test date is now reported as 28th June 4010. Hmmmm.
    Any thoughts on this, or help as to the next step will be very happily received.

    It is normal to see the spinning beach ball cursor while the drive spins up, but obviously it should go away once the drive is spun up & the iMac should not eventually lock up.
    Also, not every drive honors the spin-down command from the OS -- some spin down automatically according to their own internal timer regardless of the system preference -- but AFAIK no drive Apple ships in any Mac does this.
    So just to cover all the possibilities, can you confirm that your iMac has the original internal drive it shipped with, & that there are no external drive(s) attached to it? If you do have any external drives, does the issue persist if they are unattached?
    You might want to run Disk Utility's Verify/Repair Disk step on each drive you use to make sure a file system issue is not involved, & the Apple Hardware Test (which will require removing any non-essential peripherals like external drives & thus not test them) to see if a hardware issue is causing this.

  • External hard drive spinning down (and up) on it's own

    I thought my 5 month old external 1tb dual drive was dying at first, but now am seeing a pattern. There is a forum over at macrumors about this. http://forums.macrumors.com/showthread.php?p=445690
    I always make sure in my energy settings i have spin down external drives unchecked, because it's known that spin downs and ups can cause drives to fail sooner. Yet I now find my external drive spinning down whenever it's not in use while I'm sitting at my computer, and i hear it spin up at the most random times, even when i'm not using my computer. sometimes in the middle of the night. This did not happen in tiger.
    It's connected by firewire 800. At first I thought it was time machine but others in the macrumors forum claim it isn't that. I almost think its network activity. I'm considering using an applescript to access the drive every 5 or ten minutes automatically yet not do anything just to see if this stops it from spinning it down. I do consider this an annoyance and would hope apple will figure out what it is very soon, before it causes any detriment to the life of my expensive drive.

    did you ever find a fix for this?
    my ext FW800 drives constantly spin down, then when i do something later i get the beachball until they spin back up

  • Hard drive spins down and have to do a hard reboot

    I have an Intel iMac 3.06 (April 2008). Ever since I upgraded to Snow Leopard especially when I am using itunes (9.02) (downloading) the hard drive spins down for no reason at all.The energy settings are fine. The only option I have is to hold the power button down for 5 sec and reboot when it happens. I know this has been an issue with other intel iMacs but when the "fix" for other machines was available it said my machine did not need it. I beg to differ. This is getting very annoying as I am sure it is not doing the hard drive any good having to hard reboot all the time.
    I have tried the power management reset which has not resolved the problem.

    Hi David
    Welcome to Apple Discussions
    1. In the Energy Saver preference try setting Computer sleep: to "Never" and make sure the the box "Put the hard disk(s) to sleep when possible" is unchecked.
    2. Try resetting the System Management Controller as described in the article below.
    http://support.apple.com/kb/HT1543
    Now then if you are still having a problem you might also:
    1. Use the Restore Default button on the Energy Saver preference panel and then reselect your sleep settings.
    or
    2. Go to: Macintosh HD > Library > Preferences > SystemConfiguration and trash the "com.apple.PowerManagement.plist" which also restore's the Energy Saver preference to default, then go back to the Energy Saver preference and reselect your sleep settings.

  • Apple software RAID 0 not spinning down while not in use

    I have a G-Tech G-RAID w/ Thunderbolt, 8TB external enclosure.  It has two 4TB fujitsu drives in it, set up as RAID 0 with Apple's Disk Utility v13 (426) that ships with 10.8 Mountain Lion.  This is attached to a very cleanly installed Mid 2011 Mac Mini, which is acting as a media server.  There is basically no 3rd party software on it, because it's acting as a NFS filer server for streaming digital players around the house.
    However, I have the G-RAID set to spin down when possible in energy saver, and it's not.  It never spins down.  I have 4 external drives on this media server, ranging from USB to FW800 to the Thunderbolt drive, all from different manufacturers, and different sizes and models.  All the other drives spin down after 10 minutes.
    Not only is the checkbox "Put hard disks to sleep when possible" checked in Energy Saver, but a
    pmset -g
    reveals that the "disksleep" is set to 10 (min).
    In frustration, I have tried a lot of things including (but not limited to) removing all other hard drives and hardware, starting up with shift held (safe boot) and removing any software at all that I thought would be keeping the drive "alive."
    Finally I decided to start monitoring the drive with fs_usage, to see if I could suss out what is keeping this one drive alive.
    "fs_usage | grep DISKNAME" reveals that SystemUIServer is accessing the drive every minute, about seven times in a clump.  Considering that SystemUIServer is the peice of software that controls the little menu add-ons to the right of the menubar, I have spend a great deal of time trying to figure out what would use SystemUIServer that is accessing this drive.
    Now it's true that this drive is set up as a time machine drive, but I have disabled time machine, and spotlight, and still I get the same SystemUIServer accesses every minute.  Here is a fs_usage dump:

    As you can see, it's the same seven drive accesses every minute.  This is NOT occuring with any of my other drives.  Now, here comes my wild conjecture.  Is this something the system does because they are RAID slices?  Do OS X software RAID slices check themselves every minute? This seems to be preventing them from sleeping.
    Any help would be appreciated, I'm going nuts here.

    The second column in your fs_usage report says that iStat Menus is what is accessing your disk (Istat64).  Disable iStat Menus and I bet your issue will go away.  I know there is a module in iStat Menus to monitor drive space, but if I recall correctly, even if that module is disabled, iStat has a habit of checking drives anyhow.  I remember hearing people getting rid of istat menus in order to allow their HDs to sleep propely.
    In fact, and easy way to test this would be to reboot your Mac with the shift key held down until you see your desktop load up.  This will prevent 3rd party add-ons from loading like iStat Menus. Let me know if that works.
    Unfortunatrly this is not the problem I am having, as I've booted with shift, and I still see the  "getattrlist" accesses in my fs_usage report.
    EDIT: stupid font made your report look like iStat when it was Lstat.  So what I said about iStat Menus is probably incorrect.  But using the shift key to boot could still lead you to the correct anwer.  I'm doing testing on my end as well. Let you know if I see anything that pertains to your issue.  (I got an Lstat entry in my fs_usage when I open the drive during testing, but I have not beeing getting them an regular intervals like you do.  I would still guess that you have 3rd party software that is checking on drives periodically, and that holding shift might suss that out.)

  • In Yosemite: External Hard Drives Won't Spin Down

    Since installing Yosemite, my external (and perhaps internal) drives won't spin down in energy saver mode: 'Put hard drives to sleep when possible.' I'm using Seagate Barracuda 2TB internal drives in external Voyager Q drive bays. They seem to be getting a little too warm, I can also feel them spinning.
    Thanks!
    Steve

    Thanks for those diagnostics & remedies. Those are good to know. Performed all of them but the problem persisted. I tried swapping out different drives and discovered that it was one particular Seagate drive that wasn't spinning down. So that was the culprit. Going to check out the Seagate discussions here or on Seagate and see what can be done, probably nothing.
    Thanks much!

  • Thunderbolt Drives won't spin down and sleep in Mountain Lion

    In Lion when I put my iMac to sleep, the external Thunderbolt Drives would spin down and sleep as well. In Mountain Lion, when I put my iMac to sleep, the external Thunderbolt drives do NOT spin down and sleep. Can anyone confirm or duplicate this issue?

    I have the same behavior, however I'm using the TB to FW800 adapter. I have 6 FW800 drives in a chain. All would sleep when MBP was put to sleep under 10.8.5 (ironically fixed after 10.8.4, now broken in 10.9).
    Seeing the same issue with native TB drives makes me think it's a problem with TB software in general.

  • How Can I spin down fans? I can't!

    In kernel 2.6.23 times, without starting sensors or fancontrol daemons or any special module, only with laptop-mode-tools, fans were automatically spinned down when the laptop was "idle", not doing anything or only programming with vim.
    After a few time, fans are never spinned down, generating unnecessary noise and spending battery. I have tried the wiki method for controlling fans described here: http://wiki.archlinux.org/index.php/Fan_speed_control but sensors only show this to me:
    [root@helena david]# sensors
    coretemp-isa-0000
    Adapter: ISA adapter
    Core 0: +28.0°C (crit = +85.0°C)
    coretemp-isa-0001
    Adapter: ISA adapter
    Core 1: +28.0°C (crit = +85.0°C)
    And pwmconfig tells me this:
    /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
    I have searched the web and I found that there is a small bug in pwmconfig, but no more about how I can get fans spin down as before.
    Anyone has a solution for me?

  • How to make a external HD (FireWire or USB) spin down when no in use?

    I have a MM and want to make sure that the external HD spins down if not being used.
    Would this automatically happen if I tick the box 'Put HD to sleep when not in use' in the control panel? Or is there an other solution to make sure it does so? I have not bought a disk as of now, but would be looking at a 2.5 (Samsung HM500LI 500 GB (SpinPoint M6)) in a FireWire housing.
    Thanks

    I really have no idea because I never sleep disks. However, that's controlled by the setting in the /Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist file. The default is ten minutes if you sleep disks. Experiment with various settings by issuing this command in the Terminal.app, until you get it the way you want it:
    *sudo pmset -a disksleep XX*
    where XX is the new time in minutes.

  • External firewire drive constant spin-down/up

    I often connect an external Lacie firewire drive to my MacBook Pro for regular time machine backups. When the drive is connected and I'm using my Mac, the drive is constantly spinning and in an 'awake' state.
    The drive remains in this state for as long as the display is on. As soon as the display enters sleep mode the external drive spins down, remains in sleep mode for 30 seconds, then spins-up for 20 seconds, only to enter sleep mode again. This cycle continues endlessly causing excessive noise and needless wear and tear.
    I've unchecked put hard disk to sleep when possible in the energy saver preferences although this hasn't helped.
    Any ideas?

    Try un-checking the drive sleep box.
    What model is the drive? Is it bus-powered or does it have its own AC power supply brick? What does LaCie have to say?

  • IX2 not spinning down

    My ix2 has been running quite nicely for a long while now with 2 2tb drives in Raid 1.
    Recently I noticed it has stopped spinning down. It has gone through this before. I have not changed any settings other than keeping up with all firmware updates.
    I always have to set energy saving to 1 hour and then back to 5mins straight after it has been turned on in order for spin down to work at all. Even that is not working now. That trick came from someone else here.
    Is there any way of discovering what is keeping it awake?
    I did try sshing in before but never got very far.
    Please Lenovo cant you just make energy saving work on these things.
    Ps I have no homepage, media sharing not used and i only use the windows sharing and http protocols. Everything is kwpt as a minimum because of the enrgy saving issues.

    Hi billybo8,
    If you have any features enabled that require access to the device, the power down drives will not work. If you have the media server, personal cloud, remote access, iSCSI, or any other protocols that access the device it will not work.
    If you have everything disabled and the power down drives is still not working, you will need to contact technical support directly to create a ticket with them to further investigate and troubleshoot to determine if there is an issue with the device.

  • USB3.0 enclosure won't spin down when ejected or when Mac sleeps

    Hi,
    I just purchased two different USB3.0 2.5'' SATA enclosures to replace USB2.0 enclosures that I currently use.
    In both cases, the drive I have inserted has refused to spin down when the drive was ejected, or when the Mac it was attached to went to sleep.  I have never had this issue with USB2.0, FireWire400, FireWire800 or eSATA drives attached to these Macs.
    I've used the USB3.0 enclosures on two different Macs, one a Mac Pro, the other a MacBook Pro.  One runs Mountain Lion, the other Mavericks.  Both only have USB2.0 ports.*
    Is this a noted bug with USB3.0 drives being used on USB2.0 ports?  I can't find any evidence that it is.
    Comments on this would be welcomed, because otherwise I can see myself trawling through Amazon's range of USB3.0 enclosures until I find one that works properly - probably the most expensive
    * The Mac Pro will shortly have a PCIe USB3.0 card, hence the enclosures, but this won't help matters on my MBP.

    Received the PCIe USB 3.0 card today and was able to test the enclosures with it.  In this case, the drive still fails to spin down when ejected.  So, it's not a USB 2.0/3.0 incompatibility.  The manufacturer advised a firmware update on the enclosure, but this didn't fix the issue.
    The enclosure did spin down when the USB 3.0-equipped Mac slept, but when I woke the Mac it re-mounted a previously unmounted volume on the device, so I suspect this was more a case of the PCIe card simply entirely losing connection with the drive on sleep, and re-recognising if on wake.  This tallies with information I've read regarding the odd and unpredictable performance of USB 3.0 on older Macs.
