Sleeping Hard Drive

I have from time to time come across a piece of Software for Mac's, particularly for Mac users that use Final Cut Pro that keep the external hard drives from going to sleep. It's becoming more of an issue as of late and I'm wondering if anyone can help me with this problem. Is there a piece of software that will prevent my external hards from going to sleep in between activity.
Any help the forum can give me would be great.
All the best

Hi,
Did you try OS System preferences > Energy Saver > uncheck box " Put the hard disk(s) to sleep when possible" ?
That should work, depending on the drive

That only ups the sleep time, I think "never"=90 minutes(?) Their is a terminal command, that I can't seem to locate right now (must be on the other computer), that will actually make drives never fall asleep.

  • Acrobat wakes up sleeping hard drives unnecessarily

    Is there a way to stop Acrobat 7 from consistently waking up other hard drives that are running in sleep mode?
    I have several hard drives installed in my stand-alone desktop PC that are connected through disk controller cards and running as drives F:, G:, etc. They are used for data storage and I access them only rarely; thus I have Windows set to put them in sleep mode after 10 minutes of inactivity. Normally, they stay that way.
    But whenever I do certain simple unrelated tasks in Acrobat, such as simply closing (not even saving) an open PDF file that's stored on the (awake) C: drive, it triggers the OS to wake up each of these sleeping hard drives in sequence. Since each wake-up takes several seconds, it means a 15-20 second wait just to say, close an open PDF document. The file(s) I have open and am closing, etc., are not stored on any of these sleeping drives, and afaik no setting has been made that would require Acrobat to access these.
    All drives are set up in the simplest configuration: single-partition, no dual-boot, no OS installed on any drive except the C: drive, no network / disk-sharing.
    Running Acrobat 7.0.9 Professional, Windows 2000 SP4.
    Any suggestions for a Preferences setting or other tweak to stop this unnecessary wake-up event are greatly appreciated.

    I had the same issue which turned up when I moved from XP to Vista. I changing the power settings so the drives did not sleep because the delay caused Acrobat to hang until it did something with the drives. I still have the hanging problem but it is not a lengthy; down to 30 secs from 45-90 secs. I noticed that the error log in \roaming\adobe\acrobat\8.0\[computer name].err shows the following every time Acrobat stalls:
    080216 13:34:25 [Warning] Can't open and lock time zone table: Table 'mysql.time_zone_leap_second' doesn't exist trying to live without them

  • Why does opening Safari wake up my sleeping hard drives?

    I have the newest of the new, best of the best i7 imac which came with Lion already on it.
    I'll be editing in Final Cut Pro X(sigh) and I'll go to Safari to check my email or whatever but whenever I open Safari it wakes up my sleeping hard drives which in turn freeze Safari and Safari doesn't unfreeze until the hard drives are all the way awake?
    WHAT THE???

    I have it partitioned into 3 volumes - 1 is Time Machine, 1 is completely empty and 1 has a backup of the main drive (cloned using SuperDuper) that gets backed up only once a week.

  • W520 sleep(hard drive) issues.

    Hi,
    I'm having some issues with my W520. Almost every time I put it to sleep and transport it it stucks on waking up and I must forcefully shut it down. If I sleep it and let it stationary on the desk there is no problem no matter whether it's with or without the AC power plugged in. I have the latest versions of all the drivers, BIOS and windows updates.  The OS is Windows 7 Enterprise. I thought that it could be because of the instant resume and stay online settings, but after switching them off nothing changed.
    I read similar topics for W510, there seems to be no solution, but I'm issuing this topic as I have one additional question. While the notebook is in sleep mode I still can hear noise from it and I believe that it's coming from the hard drive, that seems to be rotating, which is very odd for me. I've tried various timer settings for shutting down the hard drive, but there is no change. And if it is the hard drive rotating probably this can cause some problems in combination with the hard drive protection while transporting it. Do you think that it is normal the hard drive to rotate in sleep mode, because for me it seems very strange?

    I have noticed sleep mode sucks a lot of battery - If you leave it asleep on battery for 24h, the battery is down about 40%.  Also, the 9cell battery wobbles about alarmingly - all things which dont help using it with sleep.  I always shut mine down before moving, as Im paranoid about it coming out of sleep while on the move and dying.  Note: when you put it to sleep, you should wait some time before its fully asleep before moving it - you dont want it to still be writing stuff to disk.

  • Sleeping hard drives on a Mac Pro

    Hi there,
    Is there anyway to forcibly sleep all hard drives other than system drive without invoking the "Put the hard disk to sleep whenever possible" on System Preferences...? Because I find it irritating that even though my Mac Pro drives are left idle, it tends to go to sleep, then waking up again a few minutes later.
    I've tried ejecting the drives manually and bringing them back via Disk Utility or other apps accessing the drives.
    However I have read that with hard drives spinning up and down, it's gonna wear them off sooner than leaving them spinning continuously.
    Any advise would be appreciated.
    Thank you.

    Has anyone else got any suggestions for this? It's the noise that bothers me. I have 4 drives installed (a mixture of Seagate & Maxtor models). Obviously the boot disk is in continuous use, but the other drives I only access maybe once a day.
    I have taken them out of Spotlight indexing and ticked the Energy Saving preference to spin them down when unused.
    Like Elphideus, my drives are not getting used but all spin up regularly. When they spin down you can really notice how much noise they all generate, even when not being used. How do I "keep them down"?
    I think it's something to do with the SATA bus getting probed, because when these drives were external in LaCie cases they would "stay down".
    There cannot be any files open/processes checking the volumes, as the drives aren't even mounted.
    I'm about to start writing a program to query the ACPI bus but it's a bit of overkill to track this down.
    Thanks,
    John

  • To sleep, or not to Sleep hard drives?

    Quick Question,
    I have two internal 250 gb hard drives. What pros/cons are there to putting the hard disks to sleep? I use one hard drive for my os/apps/data, and the 2nd hard drive for my video/audio capture/render files.

    1008/3454
    When the option "put the hard disks to sleep when possible" is enabled,
    the hard disks spin down after 10 minutes of inactivity.
    This default time is long enough for you to check this option with no worry.
    If you prefer more delay (example 20 minutes before spindown), the default delay is very easy to modify with an utility like Cocktail or TinkerTool System for example.
    In a word:
    No problem, go ahead and sleep them.

  • Hard drives go to sleep, ignores sleep settings

    I have an issue in which the hard drives will spin down (sleep) even though my computer (MacPro 1,1) is not asleep. My startup drive is an SSD, and the other four drive bays have HDDs. I have unchecked the "Put hard drive(s) to sleep when possible" in the Energy Saver preference pane. (On a side note, it's strange that this feature isn't grayed out; how does an SSD go to sleep? This is also the case with my MacBook Air.) The "Wake on LAN/Ethernet" option is also disabled. The computer is also set to Never Sleep.
    I wouldn't mind this behavior except that I've been experiencing kernel panic-level issues when the computer needs to access something on the sleeping hard drive(s) (an iTunes song, for example). I have NEVER been able to successfully wake up a sleeping hard drive in Lion. The spinning beach ball starts with the foreground app then slow starts freezing every other open app. I can Cmd+Tab to other apps, but even the Finder eventually dies. A hard reboot is the only option.
    I have just started shutting down background processes to determine if they are the root cause. Dropbox, Audiogalaxy, Skype, EyeFi Helper, and Growl: I've killed them all to determine if they might be to blame. (Again, never an issue in SL. Maybe these apps aren't Lion-compatible yet?)
    Snow Leopard never had these issues. However, SL obeyed the "Put hard drive(s) to sleep when possible" setting, which seems to be the start of my problems in Lion.
    Has anyone else had similar issues?

    Mate
    I have found a solution!
    Go to System Preferences > Energy Saver > uncheck Put Disks To Sleep
    Then...
    Launch Disk Utility (Applications > Utilities)
    Run Repair Permissions on all of your disks INCLUDING YOUR MAC HD!
    Then Verify all disks
    Then reboot....
    Hey Presto! No Disk sleeps!
    Hope it works for you too!

  • Time Machine Hard Drive will never enter sleep mode or stop spinning

    Hi, I'm just wondering if anyone could help me.
    When i recieved my MacBook I took the 80gb hard drive out, and placed it in an external USB drive case to use as my backup device, and placed a 120gb drive into the MacBook.
    Now when I'm using this drive, it never stops spinning when not in use, and when the MacBook goes to sleep, it still continues to spin, even the light continues to flash whilst the MacBook is sleeping.
    Is this because I've bought a naffy external case (it only cost £5 from ebay, it's not even branded with a manufacturers name), or will there be some settings somewhere?
    Thanks guys,
    Seb

    p.s. the external drive case is a SATA-Drive case, self powered by the USB 2 connection, there is no external power involved.

  • Time Machine hard drive is not sleeping.

    I have been using a 1TB Maxtor Basics (Seagate?) external USB hard drive for Time Machine on my iMac for over a year now without any problems, until recently. Between backups, the Time Machine HD does not go to sleep anymore. I am certain that until recently it would automatically go to sleep between backups and wake itself for each scheduled hourly backup. The USB HD is now running constantly when the iMac is awake. Has anyone else had this issue? Can anyone confirm that their "Time Machine" does in fact sleep between backups?

    Hey Pondini. It appears my Internal HD is not sleeping either.
    Since you've already replaced the preferences file (the first suspect), there may be something using both disks. If you're running any anti-virus software, turn it off (or uninstall it). Exclude both from Spotlight Indexing, if you haven't already, via +System Preferences > Spotlight > Privacy.+
    If that doesn't help, use the +Activity Monitor+ app (in your Applications/Utilities folder), to see what's running. When it starts, select either +All Processes+ or +Active Processes+ in the toolbar, and sort the list by the +% CPU+ column, so the highest numbers are on top, and select the CPU tab towards the bottom. Some system processes run more or less continually, so it's not easy to see what's using the disk(s), but you may find something. If the process(es) involved aren't familiar to you, post their names here (and/or check this out: http://triviaware.com/macprocess/all)
    I would like to do an "Erase and Instal"
    That's extreeeeeeeemly unlikely to change anything, unless you have some software that you loaded for the Maxtor (if so, just delete it and Restart).
    As another poster (Kiraly, I think) says, that's like fixing a dripping faucet by tearing out the kitchen!
    but although I know my Documents are backed-up, where are the other things like all my emails and stickies, favourites, notes etc. filed?
    What are you contemplating? Erasing your HD, installing OSX, applying the "combo," and selectively restoring things? If so, that's a large project, with very little chance of success.
    First, make a second full backup on a separate external HD, via the Restore tab of Disk Utility, CarbonCopyCloner, SuperDuper, or the like. It's rare, but on occasion a backup drive fails during a restore, and everything is lost.
    Then, here's what you'd be looking at:

    • Erase your internal HD, per the yellow box in #1 of [Formatting, Partitioning, Verifying, and Repairing Disks|http://web.me.com/pondini/AppleTips/DU.html] (or use the link in *User Tips* at the top of the +Using Snow Leopard+ forum).
    • Quit Disk Utility, and install OSX from your Snow Leopard Install disc.
    • Set up a temporary User Account (different from any on your backups).
    • Go through the set-up procedure for your Internet connection(s), power settings, and other system-wide settings and preferences.
    • Download and install the "combo" update, to get back to your current version of OSX.
    • If you've upgraded either OSX or iLife since purchasing your Mac, find the disks with iLife and restore those apps.
    • Find all the discs for 3rd-party apps and install them. Re-enter any purchase keys.
    • Find the websites for all downloaded 3rd-party apps, download and install them. Re-enter any purchase keys.
    • Restore whatever data you saved. See #28 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum) for some common data.
    • Re-enter all your Users' preferences and settings, including email accounts: account info, passwords, server names, etc. (if you didn’t save them).
    • Wonder what you missed, and find out the hard way . . . for months . . . or longer.

  • My LaCie Firewire 800 hard drive, connected to my Macbook Pro via Thunderbolt Cinema Display port, disconnects after sleep

    I have a LaCie RAID Quadra hard drive (two disks in a case set to a redundant array) which for all intents and purporses appears as a normal hard drive to my mac.
    When connected directly via FW800 to my Macbook Pro (2011, with thunderbolt port), it works perfectly.
    For the sake of convenience, and since I am using it only at home as my Time Machine drive, I connected it to the FW800 port on my Thunderbolt Cinema Display.  The display works perfectly in every way up until now.
    When connected, the drive works great.  However, when I put the machine to sleep, upon awakening it, I receive the "Disk improperly ejected" error immediately upon the screen coming up.  
    The drive is set to Auto mode which has always worked fine in the past; putting the drive to sleep when the computer is asleep, etc.
    So, I only receive the disk ejected error when it's plugged into the Cinema Display; not when directly plugged into the MBP.
    I have the 1.1 firmware update applied to the monitor.
    Any ideas?  I appreciate it.

    My desktop has two FireWire ports. In the first one I had my webcam plugged in. In the second one, the External Hard Drive. I unplugged the camera and used the first port for my External HDrive and now it works! So it seems the problem is a hardware problem with the port.
    I'd check to see if the problem returns when you plug the camera back into the second port, or if the drive works in the original port when the camera is not connected.
    Edit: Maybe you unplugged the problem, when you unplugged the camera?

  • How to stop my Time Machine external hard drive preventing iMac from sleeping?

    I have a late 2012 iMac, and have discovered that sometimes (I haven't noticed a pattern of when it doesn/doesn't happen) the computer will immediately wake up after I set it to Sleep (Apple Menu>Sleep). Through elimination I have found that it is the the USB 3.0 external hard drive I use as a Time Machine back-up that is the culprit; unplugging it then allows the computer to sleep. If I unplug it, then plug it back in later on, this normally solves the problem for a while, but not forever. This same Hard Drive didn't cause the wake problem on my previous '08 iMac.
    A big issue is that when the machine immediately wakes from sleep, the display stays off (until I move the mouse) - this is good from a power saving point of view, but means I don't know if/when the machine is immediately waking from sleep (I have to listen to the fan when setting it to Sleep mode to hear if it has actually woken back up).
    I've searched the forums, but can't find another poster with the same problem as myself. Can anyone advise a course for me to pursue to prevent this from happening?
    Thanks. Jamie

    Hi Frank. Nope, I'm still having the same symptoms; the plugged in external drive (TIme Machine) will wake the machine up a couple of seconds after it winding down when put to into sleep mode. Ejecting the drive and then sleeping the machine works. After plugging it in again to do a Time machine backup, it will allow the computer to sleep soundly for the first few sessions (eg a few days of sleeping, waking, sleeping, waking, etc), but then it will then suddenly start preventing it from sleeping again after a while.
    It seems I'm fortunate in my case that the display stays dark (or off?) when the machine has been woken from sleep, but this was actually preventing me from knowing the machine wasn't in fact asleep for quite some time; I only eventually cottoned on because there wasn't any delay when 'waking' my machine (which there normally is). I would then have to carefully listen to the spinning fans to know if in fact it had gone to sleep or not.
    So, to summarise, unfortunately no, I haven't solved this yet. If anyone else has a solution, please let us know?
    Also, I've noticed occasionally after waking that there is a relatively quiet 'crackle' sound (kind of electrical sounding) from the bottom-right area of the machine. This goes on every so often for about 30mins. I see this is also an issue with other people's late 2012 iMacs, but I've not seen if anyone has a solution to it?

  • Hard drive startup issues after extended sleep/shutdown

    Hello,
    When I put my iMac to sleep or shut it off for an extended period of time (overnight) and then try to wake it up or turn it on, the iMac makes a strange clicking noise and freezes.
    After manually shutting down and restarting it one or more times it will startup fine.
    Putting to sleep/shutting down the computer for short periods of time doesn't cause any problems.
    So when this first started happening I though "Uh oh, hard drives going to that great recycling depot in the sky."
    But, Disk Utility, Apple's hardware test, and TechTool Pro 4 all find nothing wrong with my system.
    Is there any chance this could not be an hard drive issue? Or should I just get the drive replaced and stop trying to diagnose the problem?

    You've covered the biggies already - I'd recommend a trip to the Apple store or at least a call to AppleCare. Back in the late 80's and early 90's 'stiction' was a serious problem with hard drives. A hard drive motor has very low torque; it can spin fast but it doesn't have much oomph and the lubricant used back then could harden overnight so that when the computer was booted up the drive's motor couldn't spin up the platters. Improvements in lubricants have made stiction less common today but it hasn't been eradicated and it is one of the things that might be affecting your drive. At any rate, since I can't put your computer on my bench, the best call I can make is for you to make a call. Sorry.

  • A305D-S688​6 New Hard Drive - Can't Wake From Sleep, BIOS issue

    Well I hope this is the right area and this gets listened to, I use sleep often... >.<
    Laptop is a A305D-S6886 Satellite bought from ToshibaDirect.
    So I dropped my laptop, and the HDD is busted. No biggy right? So I bought a new one. Spefically this one. It is a Western Digital, my Dell laptop friend used it, good reviews, exact equilivant to the one I use. Great!
    So I add it right in, easy enough. Boot up the laptop, install Windows 7 x64 Ultimate. Install all of my software, Toshiba software, copy all files, all updates, etc. It is done!
    Go to school next day, and while using laptop it feels funny, like it keeps hanging. Why? It hangs when I try to resume from sleep/standby OR hibernation! That won't do. I do a bit of Googling. Tried that hotfix for 1 TB or bigger SATA hard drives, didn't work. More Googling shows this is an issue with Win7 in the beta/release client, both 32 and 64 bits. Nothing on the RTM or build 7600 except for the 1 TB or bigger SATA hard drives. Hm, maybe the HDD is broken?
    With into Ubuntu 9.10 x64 Desktop edition, opened up wonderful thing called "Disk Utility." It said the following: Disk was healthy, no bad sectors, and Self-test past. Well then let's run a through SMART test! I did, and it still passed. Hm, hard drive seems perfect, so what can I do? Fiddle with BIOS settings of course! (I have version 2.10)
    So the only option I could find related to SATA or HDDs was SATA mode, which had the follow options: Compatibility or AHCI. It was on AHCI, so let's try Compatibility! That didn't work, still crashed. What is next? Let's install OEM Vista that came with my computer! (Vista SP1 x64 bit)
    So yay, it is done! Let's put it to sleep! What's this a crash? Then it is OS independent! Now to decide which hardware it could be: BIOS, or hard drive. Next up: stick it in my desktop and install Windows 7!
    So yay, w7 has installed! Put it to sleep, it works fine! Wow what could it be? I didn't have an OEM partition before, because of the new driver, could it have been an update, or maybe the BIOS? Clean install and back on laptop!
    3rd W7 install later, it crashes on sleep! OEM and software/drivers is out, so that leaves BIOS! D: This took me 2 days, and I don't think I missed any possibilities. I am pretty technically able and confident, so if you have any idea what else it could be, please reply! I use sleep often! D:
    P.S. I want more options in the BIOS! D:
    EDIT: Maybe some specs may help:
    One of the 1st A305-S6886 made I think:
    AMD Turion x2 RM-72 at 2.1 GHz
    4 GB DDR2 RAM at 800 mHz (Maybe 667 mHz)
    ATI HD 3470 and HD 3200, in "CrossFire"
    BIOS version is 2.10
    Screen size is 15.4
    Chicony WebCam is broken, due to cable tearing in the case (I voided my warrenty D
    This exact hard drive
    Windows 7 x64 Ultimate currently installed
    EDIT 2: Also, it SOMETIMES seems to resume from sleep, specifically after long periods of times in sleep mode.
    Solved!
    Go to Solution.

    Sounds like something else besides the hard drive was "busted" when you dropped it.  Does it do this when you use hybernation as well as when you use sleep?
    If you don't post your COMPLETE model number it's very difficult to assist you. Please try to post in complete sentences with punctuation, capitals, and correct spelling. Toshiba does NOT provide any direct support in these forums. All support is User to User in their spare time.

  • Hard Drive Sleep Issue

    I´ve got one problem with my Mac Pro running a fresh tiger installation. My internal hard drives go to sleep although i´ve unchecked the "enable hard drive sleep" checkbox in the energysaver prefpane. i am using 4 internal hds and after a while of one or more being inactive i can hear them spinnig up upon reactivation (doubleclick) and there is a certain delay in responsiveness (e.g. windows opening up...). Any suggestions are highly appreciated.

    There is a utility named "spindown fix" that can resolve the issue of HD's not staying up even after you've unchecked "put hard disk(s) to sleep when possible." Apparently that doesn't actually do anything
    Normally, I let my drives spin down to conserver energy and keep everything cooler, including external FW drives. But sometimes when I'm using Final Cut Pro, I don't want the delay while I await a spin up. So I uncheck "HD sleep" in energy saver and then run Spindown Fix. It seems to work.
    Search the web for "spindown fix."
    (edit): I did some more research, and at least in 10.4.11, if you have the system sleep other than "never" and don't check the HD sleep option in energy saver, the HD sleep doesn't becomre "never" but rather 180 minutes. You can verify this for your system by using the plist editor (part of development tools package delivered with 10.4) and examining libarary/preferences/systemconfiguration/com.apple.powermangement/plist
    In the AC power custom profile, you'll find the parameter Disk Sleep Time; you can examine how it varies based on your energy saver settings. Some say to set it to zero to prevent spin down form occurring every; I would not necessarily recommend that if 180 minutes is long enough for your.

  • External hard drive disappears when imac wakes up after sleep

    Hi Everyone.
    Got a really silly question but I can't seem to figure out where to fix this
    I have 4 USB 500gig hard drives all run off a 13 port powered hub.
    Now I have one hard drive set aside for my films which I and ripping so they can be view via my apple tv 2nd gen. The other is for MP3's and the other 2 get are redundunt at the moment.
    No the problem is when I rip a DVD, I rip it to the hard drive on the iMac and then trans the files to the external drive.  As I rip them at a high quality (2 to 3 gigs per film) I get the transfer box saying it will take X amount of time.  The only thing is the iMac after some minutes will go to sleep.
    When you wake it up the hard drives have disappeared and the is an error saying the drive have been ejected incorrectly.
    I'm assuming the iMc is putting the drives to sleep when it goes to sleep.
    Is there a way to keep the hard drives running but only put the momitor to sleep.  The problem is also happening when I use USB memory sticks (I have a 4/8/16 & 32gig sticks all with various bits of info that I am sorting out from the move from Windows PC to Mac.
    Can anyone point me in the right direction to get this fix coz I can't seem to find the setting
    Thanks
    Rick

    When you are doing this, set the drive to never sleep, slider completely to the right and display sleep to something like five minutes. Or just hit Control-Shift-Eject, to sleep the display. Uncheck "put the hard disks to sleep..." That said, the firmware on the externals may be spinning them down. But this shouldn't be happening if they are being written to.
