Why does my computer tell me the "Disk was not properly ejected" when waking from sleep mode?

I am a real "Newbie" to Mac OS. I have a new iMac 21.5" running OS X Lion. When I awake the computer from sleep mode with the spacebar on the keyboard, I get the message "The disk was not ejected proper, etc.". Iss there something I am doing wrong?
Thanks,
Mike G.

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.

After ejecting a disk plugged into the USB port using Finder, I am now getting "The disk was not properly ejected" message. This didn't used to happen. How can this be corrected?

When you right (control) click on the disk and click eject "disk name", do you pull it immeadiatly or wait a few seconds for it to unmount? Try waiting and see if you get the same message. If you do, when the disk is connected go to applications/utilities/disk utility, after opening DU, select the volume in question from the left side bar and try a permissions repair, you may also run verify disk and see if it comes up with any errors (they will be in red)

Workaround for the problem of ultrabay HDD ejecting when waking from sleep

After trying every possible "solutions" with no luck for the problem of the second hard drive always ejecting/disconnecting when waking from sleep in my T530, I've decided to create my own workaround.
This is by no means a definitive solution but a nice workaround that uses little resources on the machine.
The idea is to simply let a program runs constantly from the second hard drive. That way, when the HDD tries to disconnect, Windows is not allowing it and then it stays allways connected.
To make it more thansparent I decided to create a Windows service that starts when Windows boot and stops when Windows shutdown.
This Windows service is very lightweight : it does absolutely nothing and just waits indefinitively.
The trick is that it just have to be started from the second hard drive.
Here is a link to the Windows service, 32-bit and 64-bit, with the source code and scripts to install/uninstall.
Just install it anywhere on the second hard drive (D: in my case).

Works perfectly for me on my T530 with Windows 7 Pro x64.

Hmm, I have no problem with Ultrabay ejecting HDD when waking from sleep mode. At first, I went down the same
route as you did. For the first few days when I received my T530 I kept an .iso file from Ultrabay HDD always mounted.
But then I disabled all power saving options within Windows and Lenovo Power Manager and it seems to work fine.
Works both with Windows 8 (64-bit) and Windows XP Professional (32-bit).
T530: i7-3630QM, 4 GB DDR3-1600, NVS 5400M, 2x 500GB 7200RPM, 9-cell, HD+ 1600x900, Backlit US, WinXP Pro
L430: i3-2370M, 4 GB DDR3-1600, HD 3000, 320GB 7200RPM, 6-cell, HD 1366 x 768, Win7 Home Premium 64-bit

Error message "disk was not properly ejected" while syncing to iPod Classic

Hello,
I am having a terrible problem with my iPod Classic. All was fine until this morning. For some reason now when I try to sync iPod I receive several error messages. The iPod will start syncing slowly then I receive "Disk was not properly ejected". At this point the iPod disappears from left side of iTunes. The iPod still says "connected". After I click "ok" on error another error message appears saying "iPod cannot be synced, disk could not be read from or written to".
Please help, my music is all I have as I am wheelchair bound.

To be clear, I'm unsure whether or not iOS 6.0 is the latest iPod Touch software but I did get this error message when I attempted to update:
I hope this helps. Thank you!

Since updating to Lion the iMac won't recognise the external hard drive (maxtor) when waking from sleep mode,

Hi All, Since updating to Lion, my imac won't recognise the ext HDD (Maxtor) when waking from sleep mode, I have tried another port, diisc utility (Ext HDD not listed in here) but nothing works. I now find that I have to restart the imac to get the drive recognised..which is fine until the imac goes into sleep mode then I lose the drive and have to restart etc etc.....anyone suffering same issue. The Ext Drive worked perfectly until the upgrade..

Thanks for this, and apologies for delay in replying...in between seeing your post I backed up the ext hdd to another mac and used the disc utility to erase and repair and then re mounted the ext hdd. OK. I have then tested the ext hdd being recognised when waking from sleep mode a few times and everything appears to be fine. If this doesn't work (long term) I will follow the instructions as you have suggested....
I now have a new problem with my HP printer (Photosmart Plus) which is not being recognised by a new wireless router..Ok whilst the router is switch on and I have reconfigured the printer..but when the router is switched off overnight and then switched back on...I get a 'printer is not connected' message and have to go through the re configure routine all over. I am minded to think this is a router problem as the same issue is happening to my wifes Mac Book Pro (which is only a few weeks old)...any suggestions..

HT1420 why does my computer tell me i have maxed out on authorizations when none (NONE!) of my devices are authorized to play anything, I bought this music fair and square it would be nice if i could listen to it.

I've done the deauthorize schpiel in the "store" menu, which tells me I have 5 whole authorizations left, when I go to play a song that has been downloaded by itunes, it tells me I need to authorize...so i click "authorize" then I am informed I have no authorizations left. This has been goin on for years. Essentially itunes takes my money and then doesn't let me listen to songs. This only happens when accessed from my computer, if i buy it on my iphone, i can listen to it on my iphone....anyway, yeah...annoyed.

Well, I imagine this has been years, as iTS hasn't sold DRM music since what... 2009?

Why my iMac does not change picture when waking from sleep ?

My iMac has Yosemite installed, I have tried to kill the system preferences in the library but it did not solve the problem.
I restarted, PRAM, repaired system permissions, log on off, etc. and nothing, nada !
It used to work without problems, changing the picture on my desktop every time the computer was waken up.
What it could be wrong ?
I have noticed that the CPU is now above 55% most of the time and iStat says that SGProtocol Service is constantly in 99%. I don´t have a clue what that means.
Any help would be appreciated.
Thanks in advance,
Rod

OK. I found the solution.
The computer changes the picture after sleep is activated from the power button but no from a hot corner, like it used to do. Obviously is a bug.
I ruled out the iStat, SG Protocol and high CPU, which are not related with the problem.
It is not a big deal, now I set it to change the image every hour, and it works !
Thanks anyway.

I have v10.8.2 os on my mac. i use an external drive for backup which is on whenever the mac is on. whenever the mac wakes up i get the reminder that the drive was not properly ejected. i did not have this issue with snow leopard?

since i have upgraded to mountain lion i get a popup whenever my system wakes up telling me that my external drive was not ejected properly. i did not have this issue with snowleopard. i leave my hard drive on and connected for use with time machine.

HT3275 Message appears "The disk was not ejected properly...." I do not eject the disk or shut it down.

I am using an iomega external HD as my Time Machine backup drive. Occasionally I receive the message "The disk was not properly ejected...." I never eject the the disk or turn it off. The data on the drive does not appear to be affected. Any suggestions or fixes would be appreciated.

There are a lot of possibilities, unfortunately.
Does the external have it's own power supply? If so, make sure it's plugged-in to a known good outlet -- better yet, to the same good surge protector your iMac is plugged-in to -- even better, to the same U.P.S. (battery backup) your iMac is running from. That will protect them against power dips as well as power spikes, which can cause momentary disconnections.
It's possible the external isn't "spinning up" quickly enough after sleeping. Try moving the check from the Put the hard disk(s) to sleep ... box in System Preferences > Energy Saver. Some external drives respond to that setting, some don't. If that doesn't change, see if you can adjust or disable the "spin down" or sleep function of the drive (check the info that came with it, or with the maker). The older it is, the more likely it's slowing down a bit -- drives are mechanical beasties, after all, with tiny bearings and moving parts.
Try different ports, cables, and combinations of the two. A cable may be frayed invisibly; a plug that works fine in one port may not make good contact in another.

When insert my lexar USB flash drive I get the message that the disk was not readable by this computer. It has worked previous to this and I do not want to lose the data by reformatting the drive. How can I reformat this drive and not lose my data?

You can't reformat it and not wipe everything on it.
Have you tried a different USB port?
Only other option, back it up on a different computer.

Apple saw it as their responsibility since the redirection took me to the App Store. They assisted me in stopping the redirection which is occurring on many peoples iPhones. It's a have java script problem that adking is using to get you to buy their games. The websites work normal and then all of the sudden the website is taken over by adking.com. You can no longer use the website as it immediately takes you to the App Store without ever showing a popup to cancel the redirection. They were very helpful fixing the problem should others experiencing this specifically with adking.com.
No need to get defensive. I'm not the only one experiencing the problem Apple said.

Why do I keep getting the message "The disk was not ejected properly." (There is no disk in the iMac)!

For about the last two to three months, every time I wake up my iMac from sleeping, I always get the message "The disk was not ejected properly."
There is no disk in my iMac!
This is no big problem to me, as all I do is hit the "enter" key, and it disappears until the next time I wake it from a sleep.
But, WHY is this happening?

Hi WZZZ. I don't know what to look for when I opened per your instructions, but here's the images:

Why do I get the disk was not ejected properly when in sleep mode

I have time machine on with an external hard drive. Recently, after the laptop goes in to automatic sleep mode I get this "The disk was not ejected properly." I did not get that before, what changed and how can I get rid of this annoying pop up?

That may be attributable to a 'delicate' connection. Make certain that the USB is well seated. Try a different USB port. Try a different cable. Try a different enclosure. Last, perhaps the HDD is being uncooperative and should be replaced.
Ciao.

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.

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