Cannot eject USB HDD that is being used for Time Machine after upgrading to Lion

After upgrading to Lion from SL, I have had only one issue. Amazing! Great job Apple with making the process smooth, but my issue is this. Ever since the upgrade, I cannot eject the external USB HDD that I use for Time Machine. I get the following error:


The disk "Time Machine" wasn't ejected because one or more programs may be using it. To eject the disk immediately, click the Force Eject button. There is the little spinning fan and the message "Trying to eject" and then the fan disappears and where it said, "To eject the disk immediately..." it now says "You can try to eject the disk again or click Force Eject to eject it immediately." I can click Force Eject and it will work, but seems like there is an issue that needs to be addressed. Any thoughts anyone?

So this is probably not the ideal solution, but this is how I fixed it. I erased and formatted the external USB drive that I am using for Time Machine, set up Time Machine again and now it is ejecting properly. Granted I lost all of my backups, but I seem to be good now moving forward. Thanks everyone for your time, expertise and suggestions!

I've got the same problem with a DVD-R in a 2009 Macbook Pro running the most up-to-date version of OS X Lion 10.7.3. It reports 'the volume can't be ejected because it's currently in use'.


I was copying various mp3 s and pdfs of this DVD-R where I have archived them using drag and drop. It refused to copy a folder full all at once so I had to painstakingly drag and drop them one at a time.


Although I am a fairly new mac user and generally a fan of the solidity of the operating system vs windows of which I am a long term user, this is one of two things I think could be improved.


I am familiar with this kind of glitch in USB pen drives refusing to eject in windows, usually because there is some real-time indexing, backup or other ongoing operation.


i found a fantastic little free utility for windows called 'unlock' which identifies and kills either selected or all such processes allowing safe removal of a drive in Vista. Obviously it should be included in windows and maybe in 7 it is, I don't know.


I found an incredibly complex and long-winded set of instructions for removing a CD posted elsewhere on this forum, but since I know the problem is the same as the one described on this thread and the message displayed is the same, it seems most appropriate here.


As far as copying processes still running, bear in mind I last started a copy operation nearly 24 hours ago, yesterday afternoon or evening, and it is now 3pm the next day here in the UK.


So how do I 'kill process' SIMPLY, and so free up my DVD-R to eject, please? A swift answer would be appreciated, as I can't use my laptop rom drive until I can.


Also, please forward the recommendation from me and the other posters on this thread that such an 'unlock' or simple 'kill process' app be included in Mac OS X's next update, or ASAP. Or perhaps it just requires an App, like the windows 'unlock' app, which is still available , if you google it. btw.


Oh - and the difference between this and most shut down stall processes - there is no 'force quit' option offered by the displayed message or the top menu bar.


Thanks,


Rich


P.S. and if there is already a simple function, key sequence or app that does this, please tell. Perhaps I missed it, I did buy a video intro to OS X lion but it was very basic and bear in mind I am a new Mac OS user.

P.S. Amongst the masses of textpad and other windows open on my desktop, I have now found the box in which four items I set to copy yesterday - a folder and 3 pdfs, are still shown as being copied.


I have noticed these copying operations take a lot longer than in windows vista or xp. These say either 'About 2 minutes' or 'Estimating time remaining...' and are stuck like that, clearly stalled, nothing happening since yesterday.


So I guess I just have to accept those can't or wouldn't copy for some reason, too big or damaged files, and click the individual 'x' s to stop the stalled copying process.



Oh well, pity the folder won't copy as there is a lot of data in it I wanted. Never mind. C ya!
