Q: Disk not ejected properly

Hi I'm having this issue since I upgraded to Mavericks where almost every time I put my computers to sleep I get the "Disk not ejected propoerly" message and every disk but the system one is not mounted and cannot be found by Disk Utility.

 

I have a Mac Mini late 2009 and a Macbook Pro 15 mid 2009 and I'm having this issue in both machines. Never had any issues before in any of my machines, not in Leopard, Snow Leopard or Lion.

 

On my Mini I have two external USB drives and on my MBP I have a SSD, where the system is installed, and a HD (I replaced my optical drive with a bay to install the extra disk).

 

I researched the issue and found a couple of threads where people sugested to buy a 3rd party app that would unmount the disks at sleep and remount them at wake, but I think this shouldn't be a issue, since it never happened with any version of OSX I had used before.

 

Is anybody else having this issue as well? Is there any word from Apple on this subject? Can I hope for a fix?

 

Thanks

MacBook Pro, OS X Mavericks (10.9)

    I tried the new cable from Other World Computing--the one they use for their USB 3.0 drives. It is short and fairly thick, and, I assume, suited for these drives.

     

    I thought the problem had been solved, but today, two days later, I just got the DNEP message while working at the computer actively. I checked the Console messages, and at the same time the DNEP appeared, these messages showed up on the Console. Whether they help in terms of identifying the cause or are simply markers and reports of what happened, I don't know. And other than seeing a reference to the WDC driver, I have no idea what they mean.

    Now, one would think that Apple engineers could make something out of this. Maybe I should set up an AppleCare incident report. Since I no longer have AppleCare it will cost me $20 or so. If someone here who does have AppleCare active, and who has this problem with a WD External USB 3.0 drive, you might be able to submit this.

    New IMAC OS10.10/ 2 Seagate drives 1TB portable/2TB expansion same problem with both - DNEP when in sleep overnight.

     

    30 minutes with adviser plugging in/out sleep on/off about to re format drives.  Want to back up over night  so might try Jettison.

    Does not happen on Airbook running Mt Lion so cannot see why it is a drive issue.

    System config solution not suitable for 10.10 as no preferences in that folder it seems.

    Fail to understand why this still remains an issue for Apple, surely it should have been sorted by now????

    Same problem here with a new Mac Pro and a new LaCie thunderbolt 2. I noticed that the instructions for sleep and shut down are different from previous drives. They suggest to eject the LaCie first even for sleep.

    So it might be a good idea to always eject all external drives and what the heck also shut down all other items, like speakers and monitor after shutting down the mac.

    The matter is that the sleep function would now be practically useless, sleep not being needed for an SSD internal drive and all that. So shutting down the external drives for both sleep and shut down is recommended by LaCie. I'm giving it a try.

    Update: My situation is Mac Pro (late 2013) with LaCie thunderbolt2 drive 3 TB and Dell display.

    I unchecked everything that could put my mac or drive to sleep. I only checked Prevent computer form sleeping automatically when the display is off and set the sleep time to never.

    That seems to have got rid of the messages that the drive was not properly ejected, for the time being. I'll need some more time before I can confirm this definitely. But that means that the sleep function on the Mac Pro is actually not working and cannot be used.

    My local LaCie representative told me that the sleep function is a concern which happens not only with LaCie drives. It appears that the Mac or OS X is using such a low level of power that drives in sleep assume power is off and the drives shut themselves off as well.

    This is a problem they think is to be solved together with Apple so that the sleep function will be available and usable again. I also experienced the same with my MacBook Pro and a first generation LaCie thunderbolt drive.

    Just to rule out a problem with the cable LaCie is going to send me a replacement thunderbolt cable.

    Appeltjehehe :- I tried, for almost 2 years, to resolve this. I know that there seem to be many "solutions".

    In my case I finally followed advice from bfhaithOct 4, 2014 12:32 PM Re: Disk not ejected properly

     

    I think it was linked to the ECO socket removing power when the monitor went to sleep. This reduced the power needed from the ECO socket which "assumed" I had switched off and shut down the power to the drives, which were also attached to the ECO socket (i.e. working as it was supposed to)..

     

    Essentially what I have done is plugged my desktop (iMac) into a separate (non eco) socket so it receives a constant supply. My, various, external drives are in other sockets. This has removed the message/problem.

    The hard drives do power down when not in use (depending on settings in energy saver) and come back to life when the iMac wakes up.

     

    I suppose in a way this shows that the mac uses very little power when in standby which is a good thing.

     

    Might be worth plugging the Mac Pro into a separate socket to see what happens (this is probably a fairly simple operation, apart from the inevitable crawling under desks etc!!).

    That may be a good idea. But it remains a bit strange. I don't have ecosockets so the sockets I have should provide enough power at all times. One always needs lots of sockets for drives, speakers etc. New houses should be built with more sockets. I had already had the idea to install an extra power line from a socket on the stairways, but it would take some drilling.

    A good thunderbolt2 cable with 100% performance and connection would probably help as well.

    This seems to have fixed it for me:

     

    Go to System Preferences>Energy Saver and uncheck "Put hard disks to sleep when possible."  Do this on Power Adapter and Battery.

     

    I have no idea if this will lead to greater wear and tear on any of the hard disks (internal HD and external storage drives) but in the 36 hours since I made this change, I have not gotten the error once.

    This is a really persistent bug, apparently introduced after Snow Leopard. On my Mac Pro, I have gotten the improper disk ejection message in Mountain Lion, Mavericks, and Yosemite. Same hardware, obviously, and the problem occurs with everything except wonderful rock-solid Snow Leopard, where it never, ever happens. The only OS I haven't tested is Lion.

    There seems to be a new way to handle the sleep function. The new Mac Pro with SSD doesn't really need to be put to sleep. It is even better not to, because if you do the mac heats up because the fan stops working. But for the external drives that are attached there seems to be a new procedure, at least for my LaCie thunderbolt2 drives. The advised procedure is to always remove/eject the drives from the desktop, then to push the blue button in front to put it to sleep (1 second push). For a shut down you push 4 seconds. So I guess this means that the mac shouldn't be allowed to shut down the external drives. Always eject the drives first and manually put them to sleep. If you start them up again, this is supposed to give you a problem free connection.

    That's what I do now. I haven't got my MP and drives for more than a few days, so it's hard to tell whether this works at all times.

    Because it would be really annoying and probably also problematic to have drives that are ejected improperly.

    But there definitely is something weird going on.

    Is it just me or does this "new way" of handling external drives sound like a pain in the neck? I don't like it. I like having 4 internal drives in my Mac Pro. I wouldn't mind a new, faster Mac Pro but there are too many issues for me to rush into buying one now. Not sure I would want an iMac either. I guess I keep what I have as long as I can.

    That's what I have been doing for some months now, and no dreaded messages.

    In theory, ejecting the drives is enough to be safe, which means also quitting all apps linked to external files. But in practice, when the LaCie drives are not switched off via the front or rear button depending on models, for some reason the drives may start up seemingly on their own any time for a quick run, and then switch off again. This won't affect the start up files or the computer, it's just an inconvenience if the noise is a problem.

    This is not a solution for me either. I have three external drives. One is a LaCie Big, right next to my iMac. It's not too big of a pain to put that to sleep manually, but my other two external drives are in a soundproof cabinet on the other side of my office. Definitely not practical to turn those on and off every time I shut down my computer.

     

    The proper solution would be for Apple to fix this.

    You mean that the blue button sometimes flashes like it's doing some work. I've experienced that as well. But it shouldn't be a problem.

    I see your problem. The LaCie thunderbolt2 drives are very quiet, but especially the 6TB one can warm up a bit, so they need some ventilation around them.
