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)

Hi All

 

I am not sure if the fix I am about to relay will work for everyone here BUT it has certainly worked for me!

 

I have a new MBPr which I migrated from my old MBPr and immeadiatly started to get the problems described in this forum.

 

I have investigaed most of the solutions suggested here and elsewhere without any success, I did install Jettison but while this masked the problem it actually stopped most of my backups working!

 

So I called Apple support and pushed it very hard until I had a Teir 2 person on the line and she was incredibly helpful, supportive and instisted she woudl ge the problem fixed and she delivered.

 

She pinned the problem down to the migration from the older machine/prefs corruption.

 

I will try and record here exactly what we did.

 

Instructions

 

1. Pull out your ethernet cable and disable WiFi and any other network connectivity you have.

 

2. Open Finder, go to your computer and then select you Macintosh HD (or whatever you have renamed it).

 

3. Go to Macintosh HD - Library - Preferences

 

4. Scroll all the way to the bottom of the list and you ewill see a folder called SystemConfiguration

 

5. Pull this folder onto the desktop.

 

6. Go to System Preferences - Sharing and change the name of your computer, even just a litlle bit.

 

7. Reboot

 

8. Re-enable Wifi and Ethernet

 

9. If you have installed Jettison, remove it and remove it from your start up items.

 

You shoudl be good to go.

 

My machine was constantly ejecting my USB drive, even if left for onnly 10-15 minutes, since doing this I have not had one single ejection and I am into 48 plus hours of run time.

 

If you like what Jettison does but don't want to eject the disks everytime your computer sleeps and it will!, then try UnDock from the Mac App store.

 

Very similar functionality BUT it is a manual process.

 

In my case if I am going to be going out I will simply use the key combo I hae seletced Ctrl-Alt-Command plus U and all my external devices undock.

 

I really hope this helps one or more you you guys.

    Thanks for the info!

    After reading your post I've created my own setup of settings in order to fight this problem.

    In energy prefs - enabled are only Put hard disks to sleep when possible (because I think it is not so good idea to keep the drives always spinning) and Power nap. Computer sleep is set to NEVER sleep. Schedule is NOT set up (it used to be - sleep at 4 AM).

     

    I can't understand how Apple can't fix this for so long! It wasn't an issue in previous OSX versions, it was brought with Yosemite!

    My advice to everyone experiencing the problem is to send them feedback through the form: Apple - Feedback

     

    I don't have problems with my thunderbolt drives - and actually I am running OSX on an external SSD via thunderbolt dock. So this makes me wonder - what if I buy a thunderbolt hub and input my USB3 drives into it? Will this prevent the problem from happening?

    Hey - I'm the author of a utility called Jettison ( http://www.stclairsoft.com/Jettison/index.html ) and am wondering if using it will stop the USB kernel panic when the machine goes to sleep (Jettison ejects external drives before your Mac sleeps). There are actually multiple problems with OS X's handling of external drives during sleep and wakeup - I've reported several to Apple and am trying to narrow down some test cases so I can get after them some more on these issues. They just closed one of my bugs with a "works as intended" resolution status, so I'd love to get some debug data from you and re-open it...

    You're saying you got a bad test result and they got a good one so they closed it?

     

    **** that's a bit weird.

     

    I think there's an awful lot of info here for you to use and test. You will notice there is no specific make of drive that it happens with - just a likelihood, and with yosemite, almost a certainty. The only constantly externally connected drive I personally have that does NOT un-mount in sleep is an old Seagate 1 TB that I use a lot as a video dump while I'm working ie it's in constant use so always seen by the most annoying Spotlight. Spotlight loves to index things and use most of your cpu when you least want it. I was hoping that had gone away with Yosemite, but no.

     

    BUT I notice that even though Spotlight (best way to slow your computer down) is supposedly working very hard, it fails to update video files I saved an hour ago on an less used back-up external drive. That at least is a clue.

     

    I am totally shooting in the dark here but what if Spotlight is not registering any update in the system until you leave the computer alone for maybe 30 minutes? By which time it's gone to sleep and not noticed your external hard disks. No that'd be ridiculous. They "ping" don't they?

    Like I  have said before I had the DNEP with a OWC external disk drive but not with a Buffalo drive that I replaced the OWC with.  Why don't you check

    out the Buffalo drives software or whatever they are doing to solve the problem.  They must know something that the other drive makers and Apple

    doesn't know.

    Careful with your wording in forums like these - Buffalo  have not s*lved anything. They may have a less robust bit of HD code that is from the olden days like my 1TB Seagate that doesn't suffer from this stuff - newer drives do.

     

    No one, so far, has SOLV*D anything.

     

    I 'm just trying to stop searches finding this thread as "solverd" when it isn't. It is tediously ongoing, Apple. For YEARS now.

    Match an "intelligent" drive with an "intelligent" computer and it confirms Terminator and Skynet is still some way off.

    Well Buffalo works without the DNEP problem so I'd say it's solved by them at least, no matter how old or what the code is.

    Are you FULLY sure Buffalo disks new and old don't have this problem? I would search this forum thread if I knew how. If that IS the case we seem to have something to work on, or Apple does.

    I only know about my Buffalo drive which was purchased new a few months ago.  I don't know about their other drives and products.  Maybe someone

    on the forum knows more about them and their products.

    Please can you list your Buffalo HD product number (not serial number) so we have an idea what firmware it's using? Thanks.

     

    There's always a clue in the firmware...

    There are indeed several issues. There is one with the new mac pro, that shuts down the fan when it is in sleep (and the mac then heats up). There are several issues with the sleep function in connection with the new thunderbolt2 drives.

    I have now 3 LaCie thunderbolt3 drives. There was a problem with the Setup for two of those drives (when finally formatted, reading errors, and kernel panics) so I sent these back (bought from Apple btw). Some drives seem to work others don't.

    LaCie told me there is a problem with the sleep function. They are waiting for Apple to patch Yosemite. There is also a problem with the shutting down procedure. These drives create kernel panics when they are shut down (by pushing the blue button for four seconds).

    I now put my drives to sleep (one second push on the blue button; never shut them down). Then I shut down my mac if needed. It's not ideal but it works. The drives appear on the desktop again when the mac starts up again.

    I've got an other version 1 thunderbolt drive also LaCie attached to the mac, which I shut down/put to sleep (the procedure in this case is pushing the big blue button about four seconds) and push one second to get it on the desktop and working again.

    Off topic but re sleep, I have a retina iMac stuffed to the gills (yos 10.10.2), and that will go to sleep even in the middle of cpu 100% use - rendering out Cinema 4d work. What?! I have to set it to NEVER SLEEP to get stuff done overnight. Left on its own it will render ONE frame overnight, not the expected 2,000 because it's in energy saver mode - okay it was using less electricity but I got nothing done so that's all night's electricity wasted having the mac on. This is all pretty screwed up. Faster computers now but Snow Leopard was a whole lot better by a billion miles...

    I miss things behaving as you'd expect.

    And my mac being efficient (except Spotlight which is still a random annoying cpu hog - do you guys still not know what "background process" means? Don't interrupt Cinema4D or After Effects etc). Be NICE to running processes.

     

    This is all off topic.

     

    ANYWAY...

     

    Has anyone LIKED or ENJOYED Yosemite yet other than emailers? Anyone creative with deadlines etc?

    Just curious....

     

    ANYWAY...

    My Buffalo drive is the hd-pa1.otu3 and the manual has hd-patu3.  Their website is Buffalotech.com.  They have lots of different drives etc. and also

    a forum. I haven't checked them out until today but lots of info on site.  My drive is under the portable drives section.  The forum might have some help

    on it.

    Hi all. I know this isn't the answer for everyone or perhaps anyone!, however i've had these issues and been following this thread forever. For me it turned out to be the energy saving powerboard that i'd plugged the computer/drive into. When the computer slept, it turned off the peripheral sockets. A doh! moment as should have been the first thing I checked. Drive now plugged directly into the wall and hey presto! sorted. Hope that helps someone out there.

    Hello all,

     

    I have a MacBook Pro (Retina, 15-inch, Mid 2014).

    I have this issue of Disk not Ejected Properly with an external USB drive (1TB).

    The HD is used with a Case (I bought the 2.5 HD and the case).

    I bought a powered USB hub (D-Link) and every time I use the HD plugged to the USB Hub, it works perfectly.

    I suspect that the USB in my Mac does not give enough power to the external HD.
