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

    What with this and the nightmare over Pages is Apple Mac going off the boil? I have an old MacBook running mavericks and I expect to look for a replacement in the next year or so ... will I be looking at a PC? Jury is out at the moment.

    After spending way too much time on this issue, I decided to purchase a new external hard drive with a USB 3.0 connection.  At a local store that only sells Apple equipment, I purchased a Western Digital 1TB "My Passport" drive.  It utilizes a USB 3.0 connection.  I did not install any of the included WD software.  I installed it yesterday and selected it through Time Machine as the backup.  Since then there has been no self ejection and the unit has done backups as directed by Time Machine.  I consider the problem solved for me.  It is well worth the money.

    That's interesting, mmann1, my Seagate that kept ejecting has a USB 3.0 connection.  I got it it to replace my Western Digital "my Passport", because the Western Digital wouldn't mount after I got my new iMac running Mavericks (it worked fine on my old iMac running Snow Leopard).  Since I have had the Seagate plugged into a powered USB hub, I haven't had the problem of it ejecting improperly anymore.

    I just wanted to add that I also experienced this problem after installing the Yosemite Beta.  Fortunately, Robin's solution worked like a charm.  Thanks!

    It has been 6 full days since I installed the WD Passport drive that uses a USB 3.0 cable on my iMac with 10.9.3 Mavericks.  I have experienced no "disk not ejected properly" error messages.  As an experiment, I took my old Maxtor OneTouch4 external hard drive with it's USB 2.0 connection that would not work on the 10.9.2 Mavericks and installed in on our church iMac that is using 10.7 "Lion" software.  It mounted fine and has experienced no ejections.  There must either be a USB connection issue or a software issue.

    I am on mavericks and this has just started to happen for me on iMac mid 2011.

     

    Before(no issue) I had :

    Standard 1tb internal drive and a nas media centre type 500gb connected via the Ethernet..

     

    Now eject errors on my external 1tb seagate connected through usb2

    I have also got the original 1tb in an enclosure connected via usb2 and this does not have an issue. It does have an external power supply.

    The internal,drive is now a crucial 256 SSD.

     

    on wake from sleep I see the error message for both partitions of the 1tb seagate external drive..

     

     

    My gut feeling is that there is some power management issues. I'm going to scan through the Eco settings and see if there is anything going on on the seagate forums.

    I doubt that it is power issues, because it is happening with my iPod and with a 1GB thumb drive.  I don't have any heavy external drives.  I have been wanting to connect my Time Capsule to run a backup but am very much afraid to now, with this problem.

    Another update to my series of posts earlier. Now that all the boxes are unchecked in the energy saver, and now that I have the hard drive and display set to never sleep, I do not get the disk ejected message anymore. I have updated to 10.9.3, which may or may not matter - I'm going to check some boxes in the energy saver later today and let the hard disk try to sleep to see what happens while I'm out of the office. In the meantime, I have told the computer to go to sleep manually several times, and after short naps the computer wakes with the disk still connected. So the current setup works, but saves no energy. I'll update again when my energy saver settings are adjusted back to slightly-more-eco-friendly. Thanks again, Apple, I *really love* your new free OS with all its glitches (external display with their own software can be its own horrible problem...) - worth only slightly less than I paid for it.

    Final update (I hope): It appears that Mavericks 10.9.3 dealt with my issue, because after I did everything discussed above, my problem was not resolved. After the update to 9.3, I have returned all energy savings settings to their original (10.8.something) levels, and three days later with abundant sleeps in between, I have yet to experience the disk not ejected properly issue. I hope everyone else has experienced the same improvement with that update!

    sibebfica, I am glad that the Mavericks update 10.9.3 solved this issue for you.  I still had the problem with Mavericks10.9.3.   The only thing that worked for me was using a powered USB hub that doesn't allow the Seagate to go sleep. However, I see that my solution didn't work for others in this forum.

     

    kcft:  well, I guess Yosemite isn't much better!

    FWIW, I have a WD MyBook USB 3.0 1.5 TB external drive connected to a powered (low powered, not high) 3.0 USB hub connected to a MacBook Pro Retina 15" mid-2012 with a recently replaced logic board (because of HDMI problems), using 10.9.3.

     

    I have always had spontaneous disconnects of the external drive. All the WD software has been removed both by their uninstall program and manually for whatever was left. I get these disconnects whether connected to the hub or directly to the USB 3.0 port on the computer, but probably more often with the hub.

     

    Here is the latest Console log of messages before and at the time of the disconnect, and after it reconnected spontaneously. I did have "put hardware to sleep" in the power saving preferences, and I've just unchecked that based on some earlier posts here.

    I to am having this problem, I have two Seagate 3TB external Thunderbolt drives and one is permanently ejecting its self, I have given up on it now but feel that it is time that Apple dealt with this problem that only started with the arrival of Mavericks. Could it be that they no longer care about their reputation of being head and shoulders above Microsoft, because that is how it looks to me. If I could go back to Mountain Lion I would without hesitation!! It is all very well giving Mavericks away for free but looking at all the people with this problem I think we would all have rather given it a miss!

    Just got a new LaCie 2big (8TB) with Thunderbolt 2. 

     

    Same problem. Randomly, while working, it gives me the "Disk Not Ejected Properly". 

     

    Seeing all the messages here, i guess its not the drive but something in Mavericks?

    I agree with you. This discussion has gone on a long time with no help from Apple. The only external drive that I have which does not eject itself on Sleep is a LaCie which I am connecting via FireWire 800. I have 2 other external drives--one Seagate USB 3.0 (connected to a CalDigit PCI card) and, a WD drive connected to the same CalDigit card but with eSATA. I have plugged the WD and Seagate into a USB 2.0 with the same results. Is anyone having this problem with FireWire?

    A couple of months after giving up on the possibility of a solution to the DNEP problem, I noticed a folder named “Seagate” (the brand of my external HDD) in the Home/Library*/Application Support folder. Believing it was a left-over from when I used it with my 6 month old Macbook Air the very first time (when it automatically installed something called the Seagate Dashboard) I decided to delete it.  I also deleted the Seagate Dashboard icon from the System Preferences drop down.  The next time I connected my HDD to do a time machine backup, I let the screen timeout. When I hit the spacebar to bring the screen back, the DNEP message didn’t appear and it hasn’t appeared for a week since I made this simple change.

     

    The Seagate folder has since recreated itself in the Library folder, likewise the Seagate Dashboard icon in System Preferences (not sure how or why) but the DNEP problem appears to be gone. Fingers crossed.

     

    I've made no changes to my system since my last post, so this isn't the result of an update - I'm still on 10.8.5.

     

    Peter

    *The Library folder is not normally visible. I made it visible to do something unrelated – I can’t remember what – but it’s necessary to find the relevant folders.
