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)

    Had the same issue Mavericks failed to read my ext drive. Don't feel bad it's Mavericks being a POS. Never happened on Snow Leopard. Mavericks is all buggy....bzzzzzzzz

    For completeness.

     

    My machine is a late 2013 MBP Retina 15 running 10.9.2

     

    Drive is a WD 2TB 2.5, although seen similar problems with 1.5Tb 2.5 Seagate.

     

    Never seen the problem with a Thunderbolt attached drive.

     

    Never seen problem with USB 3 drive connected to USB 2 port (Thunderbolt display)

     

    Saw problem all the time with 1 particular USB 3 hub.

     

    Currently running fine (I have seen the message a couple of times in since the fix)

     

    Currnetly have the USB3 WD drive connected to a Thunderbolt docking station.

    Oh and to the person who asked, yes dragging to desktop or deleting the folder I mentioned is fine, putting it on desktop means you can recover the old one if you want.

     

    One other point of reference I DO have the 'Put Disks to Sleep' box checked!

    Robin,

    My observation is that dragging to the desktop does not delete the folder.  I dragged to the desktop, to create a copy for recovery, then deleted the folder, which required password confirmation.  This processes rehab'd two systems after the 10.9.2. update.

    Something to check: has anyone not on Mavericks (or post 10.9.2) had success with Robin's method?

    I've had one or two eject errors after doing what Robin suggested, but overall it's far less frequent than it was before.

    Ok. Good to be clear about that. Just checking if there's a case that Robin's method only works for those of us on 10.9.2. A few posts here seem to support that theory - or at least show that it reduce the frequency of the DNEP message.

     

    I'm also seeing less of it on 10.8.5, but that's because I'm doing something like Linda and only connecting my external drive when I need to backup or shift something, and I'm doing do that while I work so that my computer doesn't sleep. Robin's method didn't work for me.

     

    Despite the evidence i won't be upgrading yet. It still seems like onboard management of sleep/power in external USB3 drives via USB3 slots is the underlying problem.

    I just got a new computer (MBP Retina Late 2013, OSX 10.9.2) and this started happening to me as well, I had a mid 2012 MBP on Mavericks and it never did this. I have two WD external hard drives USB 3.0 attached to a USB hub with a power source. Only 1 of the 2 disconnects on sleep. The one that stays connected is the newer of the two, but neither are awfully old hard drives. I just called Apple today about this and they gave me case number 591057190. They had me do some funky restarting of the computer because I was also getting no audio occasionally on waking from sleep. I have just done the "fix" that Robin suggested and will weigh back in on how it worked in a few days. I am however going to call Apple again and try to get this issue elevated to Tier 2 since I've already started the process.

    Same "Disk Not Ejected Properly" problem, PLUS.

     

    On an iMac 12,2 (2012), I “upgraded” from the last Mavericks to 10.9.2, and I have had unending misery since.

     

    My 250 GB SSD from which I run OS X started acting funny, so I shut down from the software and started up again, and got spinning gears.

     

    Using Disk Utility from Recovery Disks did nothing, and DiskWarrior (long-time fan, has saved my bacon so many times) did nothing.

     

    In the meantime, I find that 2 of the 3 partitions on my 1.5 TB Seagate FreeAgent GoFlex are unavailable, and my TimeMachine backup was on one of the partitions.  DiskUtility, DiskWarrior, and TechTool start to work on the drives, but eventually the drives eject, or are not readable.

     

    I ended up reinstalling Mavericks 10.9.2 from another drive, and now it's booting up, but I'm getting lots of beachballs, and eject messages.  It's only my SeaGate drive that's doing this, though, and no my Western Digital MyBook 1.5 TB.

    I too am having the "Disk Not Ejected Properly" problem. I am using Jettison to "bandaid" the problem and I am currently working with Apple to see if we can get the problem fixed. I have tried all of the previously mentioned fixes to no avail. I am running a Mac Pro 2013 with an external Thunderbolt enclosure (OWC Thunderbay IV) which always dismounts. A bus powered 1TB OWC drive connected through a Thunderbolt to Firewire adapter doesn't exhibit the problem.

    I had a long phone call with a Level 2 Apple adviser last week and apparently "the engieers are working on it". It seems they're becoming aware of this problem (if it is just one problem) and this thread, because the Level 1 adviser wanted me to run through Robin's fix (see post on 25 Feb) before he put up the white flag and called in Level 2. In turn, Level 2 ended up suggesting I try Jettison as a temporary work-around. Hopefully I'll hear something in the next few days.

     

    In the meantime those of you still on Mountain Lion might like to check out this supplemental update, which the Level 2 adviser sent to me:  http://support.apple.com/kb/DL1686?locale=en_GB&viewlocale=en_GB   It claims to address "...an issue that may cause external drives to be ejected after the computer goes to sleep." Didn't work for me but might help someone.

    I discovered the cause of my problem with my Mac Pro 2013 and disk not ejected properly problem - my POWER STRIP! After fussing with all sorts of system level solutions it turns out my APC Energy Saver that I had been using on my Mac Pro 2006 was the culprit. Once I removed the APC Energy Saver, my Mac Pro 2013 behaves as it should upon sleep! YES!

     

    I only discovered the solutioin after googling a number of times and reading a post by a user who had an iMac and was having similar problems and removed the power saver strip (manufactured by another vendor - not APC) from the iMac and all worked fine.

     

    Go figure. Hope this solution helps someone else who might have a similar problem.

    After swapping from a USB 3.0 cable to a standard USB A->B cable I stopped getting the error messages.

    Robin's method reduced the frequency of error messages for me.

    However, I found that as long as I keep a torrent running (using Vuze) the external hard disk will not be ejected upon sleep.

    This is even though the torrent does not write or read from the external disk. Maybe it just keeps the system active.
