Mavericks: Internal HD "Not ejected properly" on wake.

Mavericks: Internal HD "Not ejected properly" on wake.
These are 2tb internal samsung drives. I know there are some WD Exteranal Drives that apparently have problems, but this is something new it seems.
Randomly, when my MacPro 2008 wakes from sleep I am getting the "Disk not ejected properly" warning, on 2 seperate drives - one may be fine the other not.
I cannot even remount it. It doesn't show in Disk Utility.
Any one have any ideas?
I've tried ENERGY SAVER / Put hard disks to sleep when possible - on and off
Mac pro 2008.

Disk Not Ejected Properly on wake

In the past week or so I am getting the standard Disk Not Ejected properly message everytime I wake my iMac up. However, all of my disks are still mounted properly and accessible so I have no idea what it thinks has been ejected.
I have been running on Mountain Lion with no issues since it became available and this problem has only just started.
Any suggestions?

I am one of those who had experienced this kind of problem. My former Time Machine disk used to automatically eject itself when my iMac sleeps, hence upon waking up my iMac. i always get the error message that the disk was not properly ejected.
From what I was able to gather from my experience, until the time that I found a workable solution, I think I can say that the problem is most probably caused by the incompatibility of certain external drives with how the iMac operates when on sleep and upon waking up. Some external drives are just not able to cope with how the iMac tries to remount a connected disk after it wakes up from sleep. There are just some external drives that cannot continue to be mounted after the iMac wakes from sleep. There are just some external drives that are not responsive enough. In other words, the existence of the problem lies with the type of external drive you are using.
My former Time Machine disk, the problematic one, was an Imation M300 Apollo 1 TB external disk. It unmounts everytime my iMac went to sleep, but does not remount after waking up the iMac. The disk will continue to be unmounted until I physically remove its USB connector and replug it in the iMac.
I replaced my former Time Machine disk with my current one, a Transcend Storejet 1 TB. And the problem went away. The Transcend disk continue to be mounted after the iMac is woken up even from the longest of sleep. I have even the energy saving option "put the hard disk to sleep..." checked. The Transcend disk comes with a Y cable, i.e. it has two USB connectors, but I only connect the one for both data and power--and it still remains mounted even after waking the iMac from sleep.
The sad realization, however, is that since there are only some external drives that are not able to work with the iMac, no matter how many those some may seem to be, it will be highly unlikely for Apple to itself fix this kind of a problem.
I, therefore, make the following recommendations:
1. Check first if your problematic disk has a firmware upgrade available. In some cases, the firmware upgrade may be enough to make the disk more responsive to the iMac waking up.
2. If there is no firmware upgrade available, check if your power/data USB cable is properly working.
3. If your power/data USB cable is in order, and the problem still persists, I think it is inevitable that you have to replace the problematic disk with a newer one that could respond well with the iMac's wake/sleep operation. With what disk will you replace your problematic one? I can only recommend from my personal experience the Transcend disk I mentioned earlier. You may also search this forum on other brands of disks that may also work.
Regards.

Finder hangs, internal HDD "not ejected properly"

My finder hangs and then it says "disc not ejected properly", which I'm pretty sure is referring to the internal HDD (in a 1TB Fusion). I know this because in iStats the HDD drops off the monitor.
Already had the HDD replaced once per Applecare when it failed their diagnostic test, but the issue came right back, and a clean install didn't work for long. Then, Apple "repaired" it because this HDD passed their test, 2 clean installs later and I still have same issue. Safe mode, PRAM/SMC reset, nothing has worked.
Anyone seen this or know what to do?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

"Disk not ejected properly" message after Maverick update

Hi there,
After uprgrading to Maverick OS, i keep getting the message "Disk Not Ejected Properly" after booting my iMac. If i close the message, ejects the external disk, which dissapeears from Finder. After few seconds message pops-up again, with my disk appearing in Finder but unable to access it.
Nothing seems to solve it. Restart, shut down, change of USB port ...
This only happened after first time of booting Maverick update ...
Any idea what i should do ? Is this a bug ?
Regards,
Simion

This is happening to me but not after reboot it just happens randomly for no reason. I have tried repairing permissions nothing showed regarding usb, verified the HD came back ok, verified the external having the issues no problems found.
Mine is a 2TB seagate desktop external usb2 connection and powered.
This for me doesn't happen under either 10.8.5 or 10.7.5 which I have on two other external HD's for testing purposes.
It only started since installing Mavericks via clean install
It can happen for me after boot up and after the desktop has been showing for any amount of time and then it just happens again and again out of the blue without any warning of any kind.
Hopefully a fix comes along soon as it is quite annoying

HDD & iPod 'not ejected properly' when iMac wakes.

Hello again folks.
I have a strange issue with my iMac and USB connected peripherals.
I have an Iomega Mac Companion HDD used for Time Machine backups and an iPod Nano (4th Gen) connected via USB (both directly to the iMac).
A while back I noticed that when waking the Mac from sleep I'd get the 'disk was not ejected properly. If possible......' message and both iPod and backup drive were disconnected.
I adjusted the energy saving properties to not put the HDDs to sleep and all was well until recently.
All I did was move the USB ports that the HDD & iPod were connected to after having a cable re-shuffle.
Ever since then whenever the mac wakes from sleep both drives are disconnected. You get the same 'not ejected properly' error, once okayed the drives pick back up.
I don't understand why all of a sudden this is happening, the option to send them to sleep hasn't changed and obviously I don't want my devices to keep disconnecting in this way.
Any advice would be really appreciated.
Many Thanks
Matt

UPDATE:
I have had to disable the sleep function on the iMac for now.
May not save me the energy but may just save my data!
If anyone reads this and does have a solution in the future then please let me know.
Thanks
Matt

"Disk Not Ejected Properly" persists in Mavericks 10.9.1

I was hoping that Mavericks 10.9.1 would solve my "Disk Not Ejected Properly" problem that started with Mavericks. No such luck. Are others having this problem?

I rechecked the box and it seemed to fix a different problem - UPS clicking. Turns out my Thunderbolt TM was disconnected for several days. So I have again unchecked and am hoping to come back to some semblance of normalcy. There are other discussions about the new chip's different energy levels and the altered choices in "energy saver" settings; and what seems to go wrong related to "sleep" or something like it.
I am surprised that Apple doesn't have a clear instruction page on sleep, energy saver settings, and how its Mavericks computers interact or may interact with the OS and its sleep options (available and hidden/inherent). While I had heard rumors that 10.9.2 would fix the external hard drive problem, I am seriously beginning to doubt it.
This is surprising as Time Machine - built in by Apple -- all but requires and external hard drive. Apple doesn't really make an external hard drive appropriate for most TMs. The LaCie 2Big 6 Thunderbolt that I use is sold through the Apple store, so, though a 3rd party device, Apple seems to be suggesting that it is compatible. Why can't Apple, until it fixes the OS, tell all of us who use an external HD for TM along with a new computer running Mavericks how to do it -- without the HD ejecting impropertly or disappearing and TM simply not backing up!! -- how to do so. I.e., tell us how to use Apple's product as intended.
Crowd-sourcing is well and good, but at Apple's prices, it is really unfair to wait for thousands of discussants to beat their heads against Apple's wall of silence, hoping to psych out Apple's 'missing instructions." Yes - there are instructions for "energy saver" settings, but they simply fail to deal with the fundamental issue of which setting makes it possible for TM to operate without needing constant attention (like turning on and off to make OS refind the HD).

Disk not ejected properly notification after upgrade

Hi,
I have a 500GB Western Digital external drive configured for Time Machine. I recently upgraded to Mavericks, now when my computer goes to sleep I get the dreaded "Disk was not ejected properly" message. With Mountain Lion I have experienced this issue when my macbook pro goes to sleep when running a vm in Parallels, but never at any other time.
It wouldn't really be a big deal, but I am connected to a thunderbolt display and when I wake the computer up, I have to unplug the thunderbolt cable and plug it back it in to get my thunderbolt display to turn back on. This is a real pain!
Not sure if this is a bug or configuration issue. Perhaps I might need a third party app like Jettison.
Please help.

Thanks for the info. I reset the SMC and my mbp starting acting very funky. I started experiencing some odd behaviour with my internet connection, so I shutdown my mbp and left it off for at least a minute. When I rebooted I was able to connect wirelessly and hit the sites I could not before.
All good; however, I noticed that my external drive was showing as a usb device and not Time Machine drive. I selected the external drive from the Time Machine prefrences and now all seems to be working fine.
I think this was the actual issue I was experiencing after upgrading. I don't think the SMC reset was necessary in this case, but I gave it a shot because I had noticed the symptom of fans running frequently when there is minimal load and proper ventilation.
Thanks.

"disk was not ejected properly" errors

I have 3 external Lacie drives (all Thunderbolt) connected to my iMac: 2 3TB drives and 1 512 GB SSD.
I back up my internal 3TB Fusion drive to both 3TB external Lacie drives at the end of each day.
(The SSD is used strictly as a scratch disk (I'm a professional landscape photographer). The SSD is always kept on, BTW.)
After I back up to these 2 3TB drives, I always eject them and then turn them off before putting the iMac to sleep. (The only time I have them running is during backups at the end of each work day.)
However, during the past couple of weeks I've been receiving the "disk was not ejected properly" error every time I wake the iMac. I'm 100% certain that each of the 3TB drives was properly ejected before turning them off (and then subsequently putting the iMac to sleep).
Restarting the iMac doesn't change the situation in the sense that every time I thereafter put the iMac to sleep I get the error message upon waking.
Any ideas....?

After doing some further testing, it appears it's the SSD.
With the two separate 3 TB completely shut down, then doing a restart with the only operating drive being the SSD, then putting the iMac to sleep, upon waking I get the same error message.
After contacting Lacie about this they advised taking two specific steps:
(1) switching the polarity of the thunderbolt cable.
This didn't help.
(2) making sure to manually eject the SSD in the Finder before putting the iMac to sleep.
This didn't help either.
I get the same error message upon waking the iMac.
After contacting Lacie a second time (today) they say that it is the Mac OS that's the problem, not the drive. I find this hard to believe, but technically I'm not expert enough to be able to know whether or not they are telling the truth. (I doubt it.)
Although I have done a Disk Utility test of the SSD and everything indeed tests out fine.

I keep receiving this message "the disc was not ejected properly. if possible, always eject a disk before unplugging it or turning it off"

i keep receiving this message "the disc was not ejected properly. if possible, always eject a disk before unplugging it or turning it off"

I had this problem too, where it seemed I couldn't go eight hours without the Duo drives dropping and getting the "disc was not ejected properly" error message.
I tried the following and so far it seems to have fixed the problem:
In System Preferences > EnergySaver, make sure the setting “Put hard disks to sleep when possible" is unchecked.
I did this only on the Power Adaptor tab, but you might want to uncheck the setting on the Battery tab as well to be safe. (In my case, the Duo drives are unlikely to be attached when I’m running on battery, so I left the setting checked for the Battery tab so that the system can still power down the internal drive.)
Since I made the above change ten days ago, the Duo disks have not dropped, even when I left the system on with the Duo disks connected for a couple of days.
FYI I have the Duo set up with two RAID 1 sets spanning the two drives. I'm using Mavericks 10.9.4.

Ever since upgrading to Lion I keep getting the error message "disk was not ejected properly."

Ever since upgrading to Lion on my iMac G5 Intel Core 2 Duo, I keep getting the error message "disk was not ejected properly." I have repaired permissions and reformatted my external LaCie 2TB USB hard disk, but the error continues. I use this disk for my Time Machine backups. This always seems to happen when the computer wakes from sleep, but not consistently. The computer was asleep overnight and backed up as soon as it awakend this morning. Two hours later I get the improper ejection message. I have used the same external disk with Snow Leopard (all versions), but never had this error message or problem. This disk has been in use without any problems since February, 2011. Upgrading to Lion is when this problem began. This is the below message (but from online image from Snow Leopard, but Lion message is essentially the same).

I had a similar issue. Mine was with a Seagate GoFlex drive. The solution was to install GoFlex for Mac 1.1.2 which included a 64-bit driver to disable the drives built in sleep timer:

I document how I discovered this in my blog post:
http://www.innerexception.com/2011/10/tale-of-computing-misery-how-to-fix.html

I am getting error message "Disk Not Ejected Properly Eject "FreeAgent GoFlex Drive" before disconnecting or turning it-" randomly.

I'm getting a "Disk Not Ejected Properly Eject “FreeAgent GoFlex Drive” before disconnecting or turning it…" message at random times. I have seen other comments about this happening after the iMac wakes from sleep. However, this is happening to me throughout the day even when I am working on the iMac.
The iMac is up to date with OS X Version 10.9. I had recently switched from a 500GB to a 3TB Drive, both are Seagate. I have never had this issue prior to the switch.
Has anyone else experienced this issue?
I verified/repaired in the Utility Disk and a message popped up indicating the GoFlex looks "OK".

No, I am not on the USB3 interface. I contacted Seagate and they indicated that there is no known issue with OS X 10.9. In my case, they are willing to send me a new Drive, since I just received the GoFlex on 12/06. Will post an update when I install the new one. Hopefully this will solve my issue.
I suggest you contact Seagate, if you haven't already, directly. The representatives are very helpful. Good luck.

"disk not ejected properly" but is still mounted on desktop?

Hi,
I get a "The disk was not ejected properly" message, yet if I go to the Finder's desktop the drive is still mounted and accessible and read/write works fine.
I've witnessed it happen once while viewing the desktop. The drive disappears momentarily for about 1.5 - 2 seconds, then shows up again. So It DOES eject, but it instantly re-mounts, and I mean in under 2 seconds and I've neder experienced a drive intentioanlly unmount/remount this fast in my life. It does happen more often when waking from sleep, but not only in that instance.
Been having this bug since OS X Lion and on to the current version of Marveicks. I am posting this under Mavericks because it's not hardware specific to anything other than USB and LaCie. I am experiencing it on multiple machines, different models, with different external LaCie drives of differing types, with different USB cables. This does not only happen when waking from sleep (as most threads seem to indicate), it sometimes happens for no reason.
The common factors:
All the external drives are LaCie drives (though vastly different models).
Both affected Macs are 2012+ models with Thunderbolt interphases and USB 3 ports (am using USB ports for USB drives, no Thunderbolt adaptors).
I could suspect LaCie, but since it's new since Lion... well you get the picture. Something leads me to suspect a bug in OS X USB protocol, possibly on software, maybe even in firmware. Might be linked to energy saving. I have "sleep drives when possible" enabled, and though it might help to turn that off (I haven't tested yet) I just don't feel I should need to, I want unused drives to spin down and save energy.

Hello there The Heftster,
It sounds like your external drives are periodically disconnecting on their own from the computer causing the prompt saying that the drive was not ejected properly. I would start by resetting the PRAM on your computer with this article:
OS X Mavericks: Reset your computer’s PRAM
http://support.apple.com/kb/ph14222
Shut down your Mac.
Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on your Mac.
Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears.Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.
Release the keys.
Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.
As well as the SMC on your computer:
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/ht3964
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
Thank you for using Apple Support Communities.
Take care,
Sterling

On opening after "sleep" I get a pop up saying "disc was not ejected properly etc. Going on for months! How can I get rid of it, please? Peter

On awakening iMac after sleep, I get a pop up saying "The disc was not ejected properly....." etc. Presumably this was a disc of photos or a slideshow I had put onto a disc at some time past. This has been going on for months. I have inserted and ejected thru Finder all the discs I have, and still it persists. Any ideas of how to get rid of it, please?

phillashby, if you just upgraded ML to 10.8.5 then the problem may be caused by a bug in the upgrade. If you look around the forum other people are having the same problem after going to 10.8.5
I recently upgraded to OS 10.8.5 and now when my iMac (late 2012) wakes from sleep I get the error mesage that my Lacie external thunderbolt raid drive has been ejected improperly. Then it reconnects right away. I will stay away from the sleep mode for the moment.

Yosemite "[Thunderbolt 2] disk not ejected properly" after sleep

Since installing Yosemite, when my Mac Pro comes out of sleep, I get a "Disk not ejected properly" for each disk drive attached by Thunderbolt 2. This all worked fine on Mavericks.
(I have a similar problem with my dual displays, which again worked fine on Mavericks - I've posted this on a different thread under Mac Pro).
The manual solution is to physically unplug the drives, but doing this more than 10 times a day is not impressing me.
Mac Pro 2014, OSX Yosemite 10.10.1, dual DELL U2713HM monitors, La Cie 2Bug Thunderbolt 2

Not sure how that helps Illaass - that thread is just another question with no answers. It might be an idea if you read the thread before suggesting it?
There is another thread that suggests a solution (link below), but I've attempted that fix with no success. I also get the "Scheduled Backup Failed" that is mentioned by others.
Re: Yosemite ejects external drives
Note that none of these issues happened before upgrading to Yosemite - everything was fine on Mavericks - and it appears as though Apple are keeping quiet on them.

Disc not ejected properly message...

Can anyone help, since updating OSX from Lion to Maverick on my MacBook now i cant open files on my CF card thats connected via a USB 3.0 Kingston Card Reader. Wether i try to open in Adobe Camera Raw, Canon DPP or just Finder i get the same result where i get a message saying 'Disc not ejected properly'. It then ejects and remounts the card continuously! My SD slot in the Macbook works fine for the record. Ive googled this issue and it seems others have previously had this issue when upgrading to earlier OSX versions. However there are no fixes as far as i can see.
I cant even upgrade the Card Readers firmware as it is a Windows download only! Im now wondering if i will have other problems with USB devices such as my Wacom Tablet.
Any help greatly appreciated.
Phil

I have the same problem with my retina pro 15. Since a downloaded Maverick Os X 10.9 I can't read my photos with the CF reader. The sistem shows the mesage Disc Not Ejected Properly.
I'm very concern about this because I can't work my photos.
