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.

 

Robin

    Same issue on an 27" IMAC Late 2012.  I have several external drives attached via USB 2 and 3 and when the system sleeps, the drives will do one of two things.. Either Go to sleep as they are supposed to or get disconnected with the "Disk not ejected properly" message when it wakes up.. Lots of data and very worried it will corrupt if this keeps up.

    Same here, 2007 iMac running Mavericks.
    I have 4 external USB drives consisting of 7 terabytes of HD space.
    After every sleep it's the "disk not ejected properly". 
    I have no problem installing 3rd party software to do a task, but NOT to fix an obvious bug from Apple!.

    I get this error as well, and my two external SSD drives are practically useless under Mavericks. Many freezes during read/writes. Have had several pretty critical issues with Mavericks so far- really regret upgrading. My fault for upgrading so early, I almost never do that. Paying for it now. Hopefully a forthcoming patch will fix at least the external drive problems, this is a real killer.

     

    Update: at least it seems Mavericks has not corrupted the data on my SSD's. I have been able to mount them on my wife's Air (w/ Mountain Lion) and copy the disks over the network. Not ideal at all, but at least this saves me days of downloading backups from Backblaze. And the SSD's are still viable.

    In my case suddenly my external drive got ejected and message appears `Disk not ejected properly'. But only few times, and no problem while sleeping or at wakeup.
    Use NoSleep extension https://code.google.com/p/macosx-nosleep-extension/downloads/detail?name=NoSleep -1.3.3.dmg

    It will avoid ur macbook from sleep while u close the lid. Its very helpful and extremely simple to use. I know this is not the solution of the problem but In case it may help u a little bit. I am using this from a long time, never had any issues with it, small and free.

    This problem originally appeared with 10.8.5.  Apple released a patch shortly thereafter and it resolved the issue for my eSata drives connected via a Thunderbolt hub, but my USB 3 drives still are affected.  No major data loss for me but folder aliases on the desktop would lose its icon, which obviously shouldn't happen. 

     

    The workaround in 10.8.5 is to disallow the machine to sleep. 

     

    Use feedback and let Apple know.

    I'm having the same issue with a USB 3.0 single drive enclosure. Mavericks keeps ejecting the drives and then I see the "disk not ejected properly" message. This is critical since these are my backup drives. It happens when my iMac goes to sleep or restarts.

    I just got a voice mail from a Apple representative about this issue.

     

    Unfortunately the connection was a little bad and the call kept interrupting, so I couldn't make out the email address he asked me to contact him...

     

    If you are reading this, please do contact me via email. As of this morning, before I left for work, the problem still persisted.

     

    Thanks

    iPhabio, did you ever get an answer on this?

     

    Ever since I upgraded to Mavericks on my early 2009 MacPro, upon wake up I get warnings that my usb3 "disk did not eject properly". I have tried everything suggested in this thread. I have contacted Seagate and have performed their firmware updates, but the problem persists.

     

    With so many forums asking this same question, how is it that no one can get an official answer from Apple??

     

    Apple-do, Where are you???

    I too had the same issue. Apple support didn't have a solution. Bought the app "Jettison" and it totally solved the problem.

    Just had a chat with Apple Support.  They suggested enabling Power Nap.  I'll give it a try this weekend (with a non-critical drive) and post whether or not it helps.

    I don't  believe the Power Nap option will work.  I have the same problem and have had that enabled for a while.  If you get better results, let us know.
