Well if you are having an eject problem, it may be indicative of a hardware problem already present.
Is your PRAM battery over 4 years old?
Are you using any system "maintenance" tools such as Onyx, Cocktail, MacKeeper, or Macaroni?
These tools can damage system caches causing system wide failures. Don't use them. The only tool you should have in your arsenal for regular use is a backup tool. All others should only be used on backed up systems and only when a technician says it needs to be used for troubleshooting.
Here's a tip I wrote about ejecting discs.
Thanks a brody. Alas, I'm not using any maintenance tools. Lion is as it was out of the box... or in this case, from the App Store.
I'll have a look at your link and hope it sheds some light on my problem
This sounds bad, and looks like a hardware problem: the optical drive is dying or has already died. Nevertheless, you say this began to happen only after upgrading to Lion, therefore a short time ago. This may suggest a software problem, I wonder how it may have happened.
What do you mean by ‘Disc utility also does not work’? What did you try to do and did not work?
Basically, when a disc is not recognised - in that it doesn't mount on the desktop - if I go into Disk Utility nothing happens. Disk Utility does not show any of the drives. I have to Force Quit it.
After the unbelievable hassle I had installing the software first time round, the last thing I really want to do is go through that process again
If I need to re-install I'll just upgrade to Snow Leopard
There should not be any hassle, also I assume to wish to at least clarify whether the drive is in good order or you have a software issue, as you seems to suggest. If you downgrade to SL and the issue is thus solved, then you have a software issue, which is OK, a lot better than a damaged optical drive.
LOL! When I installed Lion I lost all my mobileme calendar and contact entries.
Thankfully I'd backed up from SL. But it wouldn't allow me to bring the backup into SL. Even an Apple Genius couldn't figure out the problem. In the end, after hours of trial and error methods I managed to get my entries back in.
TBH, Lion has so many glitches it really would be better off going back to SL
But thanks for the advice Cattus Thraex
What would be the best way to re-install either Lion or SL?
I have been with Lion from the beginning, not because I particularly like it, but because I do know Apple is not going to support SL any more. Secondly, my 2007 MB is as fast with Lion as is with SL. Thirdly, some features are better, e.g. a better support for one multi at our university.
Cannot reproduce problems you mentioned. Besides, backuping data is a must when you install any OS, so—
I would do an erase-and-install of Lion (erase the internal disk, of course after a good backup of all data), and reinstall Lion from the scratch. I am sure you will have a good and running system.
