My iMac (Mid 2007) ejects all CD/DVD discs

Okay,
I think I have the fix.

Do any of you use Boot Camp?

I do, with Windows Vista Ultimate. I was using Vista the other day and then restarted back into my favorite OS X =], and it then started spitting out every CD that I used.

Well, I restarted holding the option key and chose my windows partition, then I put in a disk while it was booting and it didn't spit out. It read the disk fine in Vista.

I then restarted my iMac with the disc still in back into OS X and it mounted and read the disk fine. I ejected the disk, but a different disk in, and it read fine. I then ejected the disk, shut down my iMac, and turned it back on, inserted a disk, and it worked fine. I just now burned a CD with iTunes and no problems.

So, I'm thinking... that if you use boot camp... thats probably the problem. The drive probably didn't get told to go back to Mac drivers or something?

Anyway... hope this helps you guys!!!

Hopefully this will resolve this for some users, but I'm not using Boot Camp on either my Intel MacPro or Non-Intel PowerBook. So not the solution for me, but hanks for the post.

Yep. This is the same solution I just stumbled upon after having my Superdrive out of commission for several weeks. I have Windows XP via Boot Camp and once I booted into XP and back into OSX, everything was working perfectly. Seems to be an OS problem.

I have the same problem and don't have Boot Camp installed. Apple is going to replace the drive.

Exactly the same problem on my 1 year old 24" Intel iMac. One minute it was working fine, the next it was just spitting out CDs within less than a minute of my putting them in. I've reset the PRAM and run Disk Utility all to no avail. I don't run Windows on my Mac so I have no need for Boot Camp.

I have 2 more years of my AppleCare Protection Plan to run so unless someone comes up with an answer on this forum I shall have to use it.

Applecare replaced my superdrive with MATSHITA DVD-R UJ-846. It was the same as what was in there originally. It now works as expected. My problem was solved.

Same problem with my new iMac..
So i have to take my iMac with me to Apple Store.. ohh i hate that.

Luckily my 13 month-old iMac is on a 3 year AppleCare warranty.

Amsys collected it on behalf of Apple yesterday and I hope to get it back with a fully operational disc drive by Friday.

My only reservation is that if, as a lot of people on this Discussion believe, the problem is a software rather than a hardware problem then it could happen all over again!

My repair is being carried out by Amstys in the U.K. who seem very efficient and who are going to replace my Superdrive. They collected my iMac on Monday, 8th. October.

However, they have contacted me today to say that Apple are out of stock of Superdrives and that they (Apple) won't receive any until 18th. October.

I presume that there has been a "run" on Superdrives because of the well-reported problem with them. I just hope that the replacement is a good one!

Meanwhile, the wait is a pain! I'm having to get used to my Graphite 500Mhz G3 iMac all over again!

I also have experienced the same DVD drive failure - ejects all disks about 10sec after loading. I tried going to bootcamp (XP), but found the same problem, nor did going back to the OS side change things. Guessing that, like the others, my drive has gone bad 13 months after purchaes. Go figure.

It is very disappointing. I have just purchased 2 months ago (fortunately with Protection Plan) and faced this problem randomly.
As a new Mac user I did not know that there is such a mess.

Just got my brand new shiny 24" iMac, and guess what!? My drive doesn't work either. I've had this iMac on for only 2 hours and the DVD drive spits out anything I put it. Same symptoms as everyone else above. And no, I don't have BootCamp installed. The drive is a MatshitaDVD-R UJ-85-J.

I HATE it when crap like this happens!!!

this is encouraging yet so discouraging b/c i, alas, have the same problem. new imac, less than yr. old and no longer reads DVD's. seems only hope is to take back to apple. quite disappointing.

I too just had this problem on my new 24" iMac. The SuperDrive DVD drive used to work fine, but then started to eject DVDs with no user interface warning. This was when I tried to install the new version of Microsoft Office 2008 from it's install DVD. I read a bunch of hints and help ideas, and tried this idea, first start up the application "DVD Player", then insert the DVD into the iMac. This then helps the Mac OS detect the DVD, even though it is not a DVD movie disc. I was then able to close the application DVD Player, and use the Finder to run the installer successfully. Hope this helps someone.
