Q: "Disk Not Ejected Properly" error after EL Capitan goes to sleep and wakes up again.

Hi, community.

 

On public launch day, I upgraded my Macs (Mid 2010 MacBook Pro 15", Mid 2012 MacBook Peo 15", Late 2011 MacBook Air and a Mid 2010 Mac Pro) to OS X El Capitan. In general terms, the upgrade process went smooth.

 

But, I've been presenting an annoying problem:

 

Each time any of my computers go to sleep, if they have an external hard drive connected to an external USB Hub (unpowered), they present a "Disk Not Ejected Properly" error after they wake up again.

 

I didn't have any of these issues with Lion, Mountain Lion, Mavericks nor Yosemite! Only now, when I upgraded to El Capitan, things are getting annoying.

 

Does any one else present the same issues and, do you have a solution to this problem.

 

Thanks for reading.

MacBook Pro, OS X El Capitan (10.11)

    Had to edit my formerly positive post.  Well, Kelly -- your suggestion of an SMC and NVRAM reset yielded some results -- for about four hours.  But the affected disk just unmounted, followed instantly by the Disk Not Ejected Proplerly alert.  Why/how it managed four hours of uninterrupted presence on my desktop is puzzling -- particularly since it would have only lasted minutes before the resets.  Go figure.

    Well that's good news–I hope. Fingers crossed here too. I may try doing the same on my end to see if it clears up my Apple Profiler USB reporting issues.

    This was a constant problem for me through the last two versions of software. I leave my machine on almost all the time and often have safari open. Two weeks ago I switched to Chrome as my browser and the problem has not occurred since. I had disabled spotlight search from al my external drives and that had none nothing. I hope this helps some of you. If it should recur I will post that.

    To all of you who have invested so much time and effort on this THANKS.

    My conclusion after dealing with this for over two years is that there is no answer. I have tried almost everything.

    I now just leave my machine on all the time with the energy saver set for never and quit all programs that are complex enough to make the computer fan go to high.

    It also impresses me that after at least a hundred of these messages I have never had a disk problem. In fact, almost all the time the disks - I have 5 running off a USB 3 powered hub - show as active on my desktop and only the notice tells me they may have been actually ejected.

    Obviously, Apple is not in the mood to address this.

    It's Back to using Keep Drive Spinning for me.  Too bad it seems not to work for others -- which is another  of many puzzling pieces to this issue.  I've clocked sixteen hours or so since my last post without an unmount, and past experience tells me I'll not have any, ever, this way.  Instead of adding to my bug report, I'm off to thank the author of Keep Drive Spinning.

    I had two full days of sleeping and waking the iMac and no ejections until just now.

     

    "Dammm, El Capitan, back at it again with the thunderbolt drive spontaneous ejections."

     

    LaCie 6T Thunderbolt2 drive mounted upon waking, and then ejected itself about 2 minutes later with a "Disk Not Ejected Properly" error.

     

    Is anyone from Apple reading these posts? Anyone from Apple responding to Bug Reports?

    Jim, Apple does not read these, generally, although my bug report includes a link to this thread.  A number of years ago, after filing a bug report about unusual behavior from an external DVD drive, Apple did contact me for more information.  My guess is that they are reacting to the issue, if not as quickly as we might like.  I have not been contacted on this one, and I can see you haven't been, either.  One can only surmise what they are or are not doing.  I suspect, however, that we are experiencing an issue related to OS X that may be dealt with in a system software update.  The bug reports filed are the surest (and only, at least here in the forums) way to get their attention on this.

    Okay, gentlemen add me to the list–again. My MacBook Pro was rock solid this entire week, until tonight. Great! Back to square one. Well at least I won't be afraid to try and SMC reset now.

    Myaka, I was contacted tonight regarding my bug report! It was only a request to submit a sysdiagnose error report, but I guess that's something. I replied with the report and hope to hear back from them again.

     

    I am about to try sleeping my iMac for the night. Hopefully my drives come back on in the morning!

    I have done NVRAM and SMC resets several times. So far without success. It is always like Jim is describing: the issue seems to be solved but then it is back again. Unreproduceable. But this is what I am after: trying to force this error so I can report a reproducable bug report.

    So far I had no success, although I got the feeling that the ejection of the drive occours every time do a remote access to my itunes media via the apple tv or remote app and the system goes into deep sleep.

    Can anyone confirm this?

    JNewHome, you hit the nail on the head. None of us have been able to reproduce the problem.

     

    We all know that something is triggering it. We just need to determine what we're all doing that's similar. As for me, I'm not accessing my MBP remotely with iTunes or an Apple TV, but what I do use is Time Machine to automatically backup my external G-drive. Not sure if that's a factor or not.

    Okay, so I just got off the phone with G-Technology and they haven't heard anything about this issue.

     

    What I find strange is that my MBP is now correctly reporting that my G-drive is connected to a USB 3.0 Bus, which is when I started to get the "Disk Not Ejected Properly" message again, which means this issue is definitely related to a USB 3.0 or Thunderbolt connection. Now that Apple is taking this matter seriously, I'm hopeful they'll be able to determine what the heck is going on—and soon.

     

    And here's an interesting fact. The tech support rep said that Apple's System Report can't always determine the drive's serial number, so rather than inserting an N/A or something else that's more appropriate it simply inserts random numbers. Nice.

    As above. Updated to the latest software on my iMac and now getting copious disk not ejected properly messages (appears to coincide with the hourly time machine back up).  The disk in question is Seagate and managed by Time Machine on the Mac.  This had happened on a previous update and then fixed - come on Apple this is your fault and needs fixing.

    It is frustrating that this error is occurring across so many different computers and drives and types of ports. I'm currently getting the error from my thunderbolt drive, but not my USB 3.0 drives, but others are only getting the error on USB 3.0 drives. I had a run of 36 hours without an error, but the errors have returned for the last two days.

     

    90% of my errors are *immediately* after waking from sleep.

    5% of the time it's within 5 minutes of waking from sleep.
    5% of the time I can wake the iMac without an error and the drives remount.
