        Since upgrading my iMac to High Sierra Beta I somtimes got the 'Disk not ejected properly' from my Thunderbolt 2 raid (still HFS filesystem).

        After now connecting my USB 2 external disk to back up after about a minute or two it started to constantly connect and disconnect (Hole list of "Disk not ejected properly" in notifications).

         

        Connecting both disk to my Sierra MacBook Pro does not show this behavior. Any idea what is triggering this?

          Hi there!

           

          I had the same issue but with the final Release version. I had to reconnect my thunderbolt 2 drives with USB to get them to work properly.

          Seems that the  thunderbolt device framework has some issues....

           

          Regards

            I'm experiencing the same. After updating to High Sierra 10.13 I'm constantly getting "Disk not ejected properly" alerts with my Seagate Backup Plus external hard drive (directly connected to USB port on my MacBook Pro) - not only when I wake the system up from a sleep state but even while I'm actively using the computer.

             

            I use the external hard drive solely for Time Machine backups so these alerts are very frustrating!

             

            Any idea how to fix this?

                This is a suggestion, something I have tried and that seems to work for me. Go to System Preferences/ Energy Saver and uncheck "Put hard disks to sleep when possible". Try it for awhile and see if you see any improvement.

                    It seems that Apple and Microsoft can't get their USB and Thunderbolt drivers to work right. I had a whole slew of error -36 problems when 10.12 first came out. After the second update, it seemed to stabalize. Under Windows, I can't use two of the exact same USB drives on the same computer (it loads, then ejects the devices, rotating betwixt the two drives, over and over and over and over).

                     

                    I would bet that USB and TBolt use a common library and that library has issues. From past experiences, don't expect Apple to acknowledge this issue, nor address it with any urgency (it's ONLY you're data, right?). If you have a USB device you are currently using as a backup device, I would stop using it until the issue is resolved. If you have a backup device and there is another Mac on the same network, I'd transfer the device to the "properly working" Mac and then access it via File Sharing. It's slower, but infinitely safer than improper disk ejects.

                     

                    One saving grace is that the Mac file system is "journaled" and has a much better chance of recovering from a disk error than any Windows system.

                      Hi there!

                       

                      Thamks for the info, but unfortunately I never had this checked in the first place.

                      I remember that they had the same issue with the 10.12 release in the beginning...

                      I have exactly the same problem.  I'm trying another suggestion--checking off the option in system prefereces for hard disk to go to sleep.  I'll see how that works out.

                      I'm experiencing the same behaviour.

                      Macbook Pro 2016, High Sierra, USB external 2.5" hard drive (not native USB-C - connected via an adapter). After I put computer to sleep, after waking up, I get the notification about disk not ejected properly. Also, the drive automatically reconnects (I get a password prompt as the drive is encrypted). Macbook is connected to external power. It happens regardless of the "Put hard disks to sleep when possible" setting.

                        I've been noticing the exact same issue randomly on my 2016 macbook pro when my Seagate Backup Plus USB hard drives are connected.

                        All of a suddent the "disk not ejected error" pops-up. Even when the drive is not even physically moved by me. And then the hard drive re-connects automatically after a few minutes and re-appears on the desktop.

                        Can at least Apple's tech support team assign someone to look into this issue and let us know about a status update gradulally?

                          I am having the same problem.  I installed 10.13.2 today (upgraded from 10.9) on my Mac Pro (2013 6-core).  The drives in my thunderbolt RAID mount ok but are usable for only a few minutes.  After about 5 minutes or so, for no apparent reason, I get a ' Disk not ejected properly' notification and they disappear regardless of whether I am using them or they are sitting idle.  I can only get them back mounted by restarting the system. These are the main content drives for a commercial post-production facility so having them randomly disappear is a HUGE deal - not a minor issue.  I checked to see if there was any sort of firmware update or other hardware issue with my RAID and everything looks ok there.  Suggestions?

                              i'm running a 2013 Mac Pro on 10.13.2 also and having idential issues. It's completely halted my work flow. I've been in touch with apple support, and they're telling me i'm likely to have a faulty logic board, or a faulty I/O board. But seeing other people with the same issue, sounds really really unlikely.

                              Thanks for posting in here though, you've given me some real hope here.

                              Apple REALLY need to sort this, this is my busiest time of year for work, and i'm completely static.

                               

                              EDIT: i'm going into an apple store tomorrow to get the mac inspected to see if there is any issues. Will report back

                                  Thanks.  The RAID worked flawlessly on OSX10.9 right up until I updated the OS yesterday.  If it was a hardware problem it seems that the issue would have shown up earlier.   Doesn't seem a likely coincidence that the hardware just happened to go bad on the same day I upgraded.  Seems like it's something related to 10.13.2.  Will be curious to see what you find out at Apple store.

                                      yeah it's far too coincidental for multiple people to have an identical issue, on the same OS build. I'll let you know how it goes, but what i'm planning to do is to wipe the machine, downgrade to Yosemite (i think the pre-installed OS), and then try my hard drives and see if that fixes it.

                                       

                                      It's worth noting that i'm not using a RAID system, i've just got a 2tb USB HDD and a 5tb USB HDD, both of which eject at the same time.

                                       

                                      Also, when i ran a self diagnostics test on the machine, it came up telling me there was an issue with the thunderbolt hardware, maybe it's worth trying this on yours and seeing if you get a similar response?

                                        went into the apple retailer i was recomened to by apple today. One of th emost useless experiences of my life, had a guy that had never seen a Mac Pro before in his life, so was too scared to take a look at it, or even power it on. He simply told me, if i wanted anything looked at, it'd have to be sent away for £50, just plain refused to discuss anything with me.

                                         

                                        So i'm going to try and downgrade to Yosemite, or whatever OS this came with, then i'm going to see if the issue persists from there. Wish me luck, gonna be a long few days

                                    Just chiming in to say i'm having similar issues on my 2013 Mac Pro (the Bin Pro). I'm having external HDD's eject midway through work regardless of the 'put hard disks to sleep' check. Once they eject, they have issues recognising the hard drive again.

                                     

                                    I've got an appointment with apple store tomorrow to get my I/O board and Logic Board inspected, as i've been told by multiple apple employes that it's going to need replacing.

                                     

                                    This thread has given me some hope that it's a software bug rather than a hardware issue with me.

                                     

                                    My bank is hopeful as well..

                                      Same problem here. 10.13.2, iMac 2017 27"

                                       

                                      So far, have only seen problem on USB. Has trashed backup on drive once. Was hoping to try Thunderbolt, but from this useful forum it looks like that this might be problematic too. Apple need to address this as a matter of priority.

                                        I'm not a developer but found this thread via google for the same problem. Just bought an iMac 2017 27" running 10.13.2 and set it up 3 days ago. I have a burly system of external drives connected via USB3. At first the drives were just ejecting randomly whether the machine was sleeping or in use. I unchecked 'put hard disks to sleep' and that solved some of it. Now they stay mounted consistently except when I put the computer to sleep - then they all dismount and I get the error messages that the drives ejected. Overnight they have ejected and remounted themselves up to 6 times as I will have 24 error messages to close in the morning but not now that I only put the display to sleep.

                                            so I was getting all these error and not ejected properly  messages on my MacBook Pro 2016 ru\nning t\he latest OS high Sierra, and the hard drive just stopped working across all devices. Looks like my seagate 4 tb portable is fried. Now for the data recovery and a new hard drive. I have ju\st ordered a USb C hard drive. Hopefully that fares better. Sheez. What a waste, Apple! You just cost me a bundle of time and money. Phoooey to High Sierra. Stay away if you can.

                                            I am having the same issue. I am a video editor and I am using Adobe Premiere Pro CC 12.0.0 on macOS High Sierra 10.13.1 on a BRAND NEW 2017 iMac 27". Randomly when editing (and I do mean RANDOMLY) I get this dreaded "Disk Not Ejected Properly" with regard to the LaCie 12 TB external harddrive that I am using that has the footage on it. Sometimes I can keep editing. Sometimes I cannot. It seems to be getting worse. This is a VERY BIG PROBLEM as I have to reboot CONSTANTLY and I am losing valuable time on my editing. I very seriously need a fix for this. Note that I have unchecked the "put hard disks to sleep" and that seemed to help slighly at first, but now I am having to reboot and remount my drive over and over and over. Someone. Please. Fix. This.

                                                Apple Support recommended I reset the SMC, which I was very skeptical of as a solution due to its simplicity. It worked for a little bit and the problem has now persisted, but maybe it works for some of you out there. Here are the (very easy) steps:

                                                 

                                                1 Choose Apple menu > Shut Down.

                                                2 After your Mac shuts down, unplug the power cord.

                                                3 Wait 15 seconds.

                                                4 Plug the power cord back in.

                                                5 Wait 5 seconds, then press the power button again to turn on your Mac.

                                                      I've tried that to no avail. Sometimes the moment I boot up it comes up with the error. Sometimes it is three hours. Sometimes it is ten minutes. It seems to be totally at random. I could be idle or working - there seems to be no pattern whatsoever. Note that I have the drive connected using a Thunderbolt Mini connected to an Apple brand adapter for the older style Thunderbolt to plug into the LaCie drive. Not sure if that is part of the issue or not - but I have no choice as there is no other way to connect the drive.

Perhaps a the OSX developers could include a permanent updated that could fix this? Or is there a some code to eneble some incative support via Terminal?

                                                           

                                                          Any work around at all would really be useful.

                                                              Music professional using High Sierra 10.13.3, new Macbook Pro w touchbar. 1 week old. My main Glyph Studio Mini is connected for two seconds and then i get "disk not ejected properly" ...then it mounts, then its ejected, ad infinitum....

Expecting a call tomorrow from tech help supposrt but not feeling confident.

                                                               

                                                              The same drive works perfectly on my mid-2010 MBP and has so for the last 2.5 years.

                                                               

                                                              This is SO frustrating! I can't even copy a large file from the drive to the desk top without the drive being ejected. Can't work!!

                                                                  I had this exact problem when I installed a Western Digital "My Password Pro" Thunderbolt drive : it mounted for 2 seconds and then automatically ejected, with the warning "Disk not ejected properly". And then it started all over again.

                                                                  Now, launching this software will install a Startup item (I forgot its name) in the User/Startup Items Preferences which will then launch upon Restart.

                                                                  Removing this Startup item cured the eject problem forever.

I checked the Startupitems folder anyway but nothing there... what you suggested has made me wonder if the drive is actually running something in the background.... thx again.

                                                                    - Your drive needs to be Mac OS Extended (Journaled)

                                                                    --It is

                                                                    - It needs to be reformatted with APFS, but then it won't work on older Macs

                                                                    -- It also works on Windows machines

                                                                    - It has been a struggle for us too. Probably a sign of greater things to come

                                                                     

                                                                    So basically reformat your drive (I'm dubious that will even work) to APFS. Even though I have another drive that works and is NOT APFS type.

                                                                    Or don't upgrade to High Sierra.

                                                                    Or...just hope it mysteriously fixes itself

Everytime the 2017 sleeps the target display disconnects, as well as the 4 USB 3.0 drives. The target display is connected to the USB-c and the other drives to the USB 3.0. I installed Mountain to remount if this happens, and I get a Kernal Panic when it tries to mount all the drives. I will try one at a time next.
