Jun 2, 2013 2:21 PM in response to wjackmanby E Sheard,I am running Mountain Lion 10.8.3 on iMac 27-inch, Late 2012.
Processor 3.4 GHz Intel Core i7
Memory 16 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GTX 680MX 2048 MB
Software OS X 10.8.3 (12D78)
I amusing apples Thunderbolt to Firewire Adapter to connect to my 2 TB OWC external hard drive via Firewire 800. I then have a 2nd OWV 3TB external drive connected via 800 Firewire to my backup drive. The 3TB is not turned on unless I want to store a movie from EyeTV.
The backup is saying "preparing backup" but never start the backup. The backup drive still appears on the desktop. I have to power the backup drive off. when I do I get the error message "The3 disk was not ejected properly. If possible ….". Then I power the drive back up. It mounts and it can click "Back Up Now" and away it goes.

Jun 8, 2013 8:03 AM in response to AMCarter3by eosman,So I have made some head way regarding this odd problem. Turns out my memory card reader is fine I think. My memory card reader will eject on the right port using a 4GB Lexar 133X professional CF card but NOT on the left USB port. However ALL 3 of my sandisk CF cards work fine in the reader on both USB ports. These 3 cards range from all different speeds from 15MB/sex to 30MB/sec. My lexar is 20MB/sec rated. Go figure!?
As for the Western Digital My passport USB 3.0 drive I have come to the conclusion its the drive and not the port. Reading through various forums on Anandtech, Apple Support and the Western Digital website forum many people have had issues with these drives on USB 3 ports on both Windows and on the Mac.

I picked up a Seagate USB 3 hard drive powered by the USB port and its working flawlessly on my RIGHT usb port. Finally

Jun 22, 2013 2:56 AM in response to eosmanby lunar boy,Having a similar problem with my brand new air. Having read through this thread there doesn't seem to be any quick way to resolve this, any suggestions?
Model Name: MacBook Air Model Identifier: MacBookAir6,2 Processor Name: Intel Core i7 Processor Speed: 1.7 GHz Number of Processors: 1 Total Number of Cores: 2 L2 Cache (per Core): 256 KB L3 Cache: 4 MB Memory: 8 GB
with a WD 1Tb passport (powerless) drive that I use for backups randonmly gets kicked out with the improperly ejected message and kills the backup :-( I'm assuming its a power issue? what do I do to resolve this?
-
Jun 22, 2013 11:36 AM in response to lunar boyby eosman,Its most likely the WD drive that is the issue. I switched to a powerless seagate usb 3 drive and have had no issues at all. I wish my WD drive worked. Take a look at my previous post with the link to the WD forums. Its ths drive in my opinion thats the issue.

Jun 23, 2013 12:54 PM in response to eosmanby lunar boy,Thanks, will investigate further.
But for reference its the same drive I've been using for 2 years with my old macbook so it seems sensible to assume its the fault of the new air no?? Anyone know if its possible to adjust the power level of the USB port to 'tweak it up' a little?
-
Jun 24, 2013 8:59 AM in response to lunar boyby eosman,You cannot adjust the power output at all on any usb port. The best thing you can do is to buy a USB 3 hub with its own AC wall power adapter.
My WD drive works fine on USB 2 ports on any of my other computers. It just has issues with some USB3 ports. If you go through the WD forums there are people there having problems with these drives on PC custom built computers, laptops, macbooks, you name it.
I will say though the WD drive seems to use more power than the seagate and that might be the issue but I am only speculating.

Jul 4, 2013 4:15 AM in response to E Sheardby Shivalab,hi,
i too have this problem, i have a lacie rugged TB disk and its always ejecting itself, already make damage to files in there, lost backups, i spent a lot of money on the imac and a lot of money on a Lacie TB disk that dosent work, i tried TB connection on a Windows machine and it worked very fine, i already bought a Apple TB cable and the problem on OSX ML still persists.
I´m going to sell my IPAD2 my Ipod Nano and my IMAC, i´m very dissapointing with the way that apple take care of its customers, im going back to Windows machine, we pay a fortune to have Apple products and no solutions for simple problems as Thunderbolt ejecting spontaneous.
best regards

Jul 23, 2013 10:09 PM in response to wjackmanby Cardano,I had the problem of a continuously self-ejecting hard disk (HD) and solved it as follows:
System:
- iMac 2013 model, 3.2 GHz Intel Core i5, 8 GB Memory,
- OSX 10.8.4
- External hard disk WD MyBook essential 3 TB (WD) used with TimeMachine (TM)
Problem:
- WD ejected itself after about ca. 20 min and interrupted TM back-ups, giving the usual error message
- I noted this while using TM, but it seems the self-eject happened also without using TM (don't recall, because I use WD only for TM backups)
My Analysis:
- The iMac treated this as someone disconnecting my WD.
- As this occurs with many different HDs, it is probably not a HD issue
- Power on HD was on all the time (external power supply) so that could also be ruled out
- I thought it might the energy saver settings (as other posts thought) making the HD stop, as that made most sense, but changing these alone did not work
- Then I thought it would probably that plus some other program storing old energy preferences (with TM as the likely culprit)
Solution:
- I updated the WD firmware (I am not sure that was necessary, but it could not harm either) - see your manufacturer's instructions for that
- I reset the energy options on the iMac (go to Preferences/Energy Saver and untick the first box (Put hard disks to sleep when possible) as well as the third box (Allow power button to put the computer to sleep). I am not sure the second untick is necessary, but I found than in another post, and I did not like that feature anyway
- I deleted the preferences file for TM (Click on Macintosh HD so the Finder opens, go to Library/Preferences/ and delete the file called "com.apple.TimeMachine.plist". The computer will create a new one.)
Result:
- I have not had that problem again for about 48 hours.
- Maybe to early to tell, but at least so far my theory has worked. Hopefully this will benefit others.

Jul 23, 2013 10:25 PM in response to Cardanoby AMCarter3,It's a bit early to tell IF you have come up with a solution. In the mean time, how did you update the firmware on you WD drive?
-
Jul 23, 2013 11:54 PM in response to AMCarter3by Cardano,You are right, as I said myself it is early, but it has worked for three days now.
WD has a firmware updater program on their website which you can download.

Jul 24, 2013 7:12 AM in response to Cardanoby AMCarter3,Cardano,
I did not find a firmware update WD's support page, but did find two possibilities for my Passport Elite : 1) WD Drive Manager; and 2) WD Macintosh + Turbo Drivers <http://bit.ly/16ZpePj>. Are either of these what you are referring to or is there some other "Firmware" update? Thanks for you help with this. (I'm still getting one improper disk ejection per day.

I tried the same thing about a week ago an am pleased to report this might be the fix we're looking for. The firmware update seems to be the one that fixes it. No timemachine preferences or time machine used here on the new air so thats not the porblem. It might be the energy settings as you suggest and I changed mine to fit your recommendations.
Personally I feel its the firmware that fixed the problem 6 days and counting :-)

Jul 24, 2013 9:12 AM in response to lunar boyby AMCarter3,You've got a new Passport. Mine is the "Elite" and there appears to be no firmware update for it. I've sent a request to tech support about this.

Aug 25, 2013 10:34 PM in response to AMCarter3by davedpss,I am yet another user who is having this problem. I've read through this entire thread as well as others an the one thing I am certain of is that Apple's response to this problem is pitiful. There are too many different drives, interfaces, power sources etc. to think that it is a third party issue. The only constant is Apple (Yes, there are some variations of machine and OS (Lion and Mt. Lion) but I'm betting this is an Apple problem.
I am running a MacMini server, 10.7.5 and multiple Seagate Backup Plus 3TB drives - these are not bus powered, they have their own adapter per drive. Macmini is usb 2 and drives are usb 3. Using Retrospect server to do backups. The drives had been working fine for 3 months or so and then I ran a server update to 10.7.5 and started having these problems with the "disk not ejected properly..." errors.
i have lost data and had to rebuild the entire server from the ground up. I have quit using the usb drives and have been running a single backup nightly to a 1TB Lacie portable drive that is firewire 800 and bus powered. This has worked for the past month and a half with no problems.
Maybe this has been fixed since there are no posts here for the last month. If so or if anyone knows of a fix, I would greatly appreciate any help.
Thanks.
Dave.

Aug 26, 2013 12:00 AM in response to davedpssby AMCarter3,It has not been fixed as far as I can tell. I have 2 USB backup drives. At least once a day, I get the "improper ejection" error message, usually when I wake the computer after it's been asleep for several hours. The strange thing is that neither drive is actually ejected. Or, if one of them was ejected, it is re-mounted automatically.
