Disk wasn't ejected properly..Error

All of a sudden, when my late 2012 iMac wakes from sleep it wakes with a white screen and then takes about 4 seconds to get to the usual desktop screen where I enter my password..
When I log back in it says 'disk wasn't ejected properly' ..
All I have plugged in is a DVD burner and a Lacie thunderbolt drive, as well as my SSD Internal Mac Drive..
So basically I'm working away on my computer video editing, I come back a few hours later and the computer is in sleep mode and when it wakes up I get the error..
Does anyone know why all of a sudden this could be happening or a way I can troubleshoot? Disk Utility verifies that my diskjs are fine by the way.

If your OS is 10.8.5 then this is a known issue. A fix is in the works.

The Dreaded 'Disk Wasn't Ejected Properly' Error Message

Hi,
brand new machine - hooked up an external USB 3 drive and switched Time Machine on.
When the computer sleeps, it awakes to 'Disk Wasn't Ejected Properly' error message.
Apple Support weren't much support, they had NO fix.
Any ideas?

If your OS is 10.8.5 then this is a known issue. A fix is in the works.

"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.

"Disk was not ejected properly" error message consistently

I have had my new Mac Mini for about three weeks. I keep getting an error message that the disk was not ejected properly. It pops up consistently about every 15 minutes or so while I am working. I am not ejecting any disks when it pops up. It will not stop and it is very annoying when it interferes with anything I am doing. I have to hit 'OK' every single time in order to get rid of it. Can anyone help me figure out how to get rid of this? I have read of a few other people with the same issue but no one seems to be able to offer any suggestions.
Thanks

"Disk was not ejected properly" error shows up everytime I wake up my imac... started a days back

This started a few days back when I updated my Mac OS X. Not sure it's related but that's when this issues started. I can see it's due to my external HD (seagate go flex 1.5T, TB connected) from the log file but not sure why this is happening all of a sudden.
Any way I can fix this issue? I properly ejected and re-connected the drive but the problem still persiste. I set up my iMac to go to sleep after one hour of inactiveness by the way.
Appreciate any tips for this.

Try running the combo updater. It fixed a lot of problems for people when 10.8.4 was released.
10.8.5 Combo Update
Based on other discussions, this seems to be a 10.8.5 bug. Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

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 unplugged a USB data device without ejecting it properly via 'Finder'. Now whenever I plug in the device I received an error message stating that the 'disk was not ejected properly

Now when I plug in the device I receive an error message stating that the disk was not ejected properly & that next time I connect the 'disk', MAC OS X will attempt to repair any damage to the information on the disk.
It has not repaired.
The data I am trying to import is photos & even when I change to a different SD card I receive the same message.
I am a recent convert from Windows and am new to the MAC way of things.

You can repair the SD card using Disk Utility.
I suggest you copy the photos from your SD card, if you haven't done so already, before using Disk Utility to repair your SD card.

Mountain Lion Upgrade, now I am getting a "disk not ejected properly" error

I just upgraded to Mountain Lion and I am getting a "disk not ejected properly" error on my external time machine backup drive. Can I fix this myself?

Maybe the Seagate needs some firmware or other update to be compatible. Tried Google or Seagate for any info?
Sometimes with TM you almost need to start fresh... keep what you have as is as backup archive.
And don't use just one backup set or method. Redundant, one off line, and clone your volumes in addition to what TM offers.
If you can only use it via USB what about FW or eSATA?

Error I get when iPod Nano 3rd Gen is plugged into iTunes: The disk was not ejected properly. If possible, always eject a disk before unplugging it or turning it off.

I have an iPod Nano 3rd Generation (2007), and When I plug the USB in and all that, the Apple logo appears then goes to menu quickly, then to a "Connected" screen, and it shows up in iTunes for about 5 seocnds before I get this error:
"The disk was not ejected properly. If possible, always eject a disk before unplugging it or turning it off."
.....I have no idea what to do, so help! please

have you tried using the Restore option in iTunes to reset the entire iPod?

Popping error message "The disk was not ejected properly"

Although I am rejecting my external hard disks, still when I unplug them the error message "The disk was not ejected properly" pops up.
Worth to note that disks are not in sleep.
My McPro is running OS X Lion.

I've been following this issue for a long time on one of the other Apple forum discussions. A suggestion was made to install an app called Jettison (by St. Clair Software). Since doing this two days ago, I have not seen the infamous "improper ejection" error message. Jettison seems to do, automatically without any effort on my part, exactly what the developer says: "Jettison eliminates the hassle of manually ejecting external drives before you put your MacBook to sleep and remounting them when it wakes."
By automatically unmounting my two external USB drives when the computer goes to sleep, Jettison is eliminating the opportunity for Apple's faulty USB power management system to improperly eject my external drives. As soon as my computer wakes up, Jettison quickly remounts the external drives. And, most importantly, Jettison has NOT caused any conflict with my Time Machine backups or my SuperDuper clone backups (three of which are scheduled to run automatically at 1:00am every night.
See: <http://stclairsoft.com/Jettison/index.html>

Error statement - "the disk was not ejected properly."

Error statement - "the disk was not ejected properly." I have my back disk pluged into my computer and when goes to sleep at night it gives me this error, how can I fix it.

Has any one come up with a solution to the "the disk was not ejected properly" when using time machine with an iMac and seagate back up drive?

I recently bought an iMac and love it.
Only proplem I have is I keep getting an error message "the disk was not ejected properly"
Everything is backing up fine on my Seagate 2TB external USB drive.
Each time there is access on the seagate and it stops in between needing to back up again I get this message.
Can anyone help?

The drive is malfunctioning.
If the drive has more than one interface (USB, FireWire, Thunderbolt, eSATA), try one of the other interfaces.
Check that the data cable is securely inserted at both ends.
Try a different cable.
If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
If you're connecting it directly, try a different port.
Disconnect all other devices on the bus, or as many as possible.
If the drive is bus-powered, but has an AC adapter, connect the adapter.
If the drive doesn't work under any of the above conditions, it has to be replaced. You may be able to salvage the mechanism by removing it from the enclosure and installing it in another one, or in a drive dock.

Since installing OS 10.8 keep getting "This disk was not ejected properly" messages. Why?

Since I installed Mountain Lion (OS 10.8) on my Mac Book Pro (early 2011), I keep getting "This disk was not ejected properly" messages. No yet sure what I do preceeding this occurence. Anyone else have this problem?

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.

The disk was not ejected properly message

Ever since I started using Mountain Lion, I have been getting a pop-up message "The disk was not ejected properly". I get this frequently, click the OK button on and continue. I do not know what disk it is referring to (I have several USB-connected storage devices) and all seem to be working and accessible. This occurs randomly while I am using the computer and I have not hit any "eject" button or touched any part of my iMac other than the keyboard and touchpad.
This is annoying and I do not know which disk it is referring to, nor how to correct the problem.

I'm having the same issue described here. I'm using a MacBook Air (11-inch, Mid 2011 edition) with a Western Digital My Passport 1 TB drive. I first experienced it with a USB3 capable model. After seeing this error occur, I was able to get the drive replaced by Western Digital, thinking it was a fault with the drive. Well, the replacement arrived today and I plugged it in and started a new Time Capsule backup to it and within a few minutes got the same message.
So I'm starting to think this is an OS issue.
