Does both drives ejects the discs ? When did this problem started ?
Customer: replied 2 years ago.
Many months ago but I did not pay much attention as I rarely use the optical drives now. Furthermore I could use my MacBook drive if needed.
Expert:  Ashik replied 2 years ago.
What version of Mac OS X are you using ? Does they eject only DVDs or does they ejects CDs too ?
Customer: replied 2 years ago.
OS X 10.8
I don't know. I only have music CD's and they work.
Expert:  Ashik replied 2 years ago.
So the drives are ejecting only DVDs ?
Customer: replied 2 years ago.
yes

Reset the PRAM and NVRAM of your Mac and see if it works or not

Reset PRAM and NVRAM

  1. Shut down your Mac
  2. Locate the following keys on the keyboard: Command, Option, P, and R.
  3. Turn on the computer.
  4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears and before the chime sound.
  5. Hold the keys down until the computer restarts and you hear the startup sound for three times.
  6. Release the keys and let the Mac bootup.

 

 

Let me know if that didn't worked, so we continue troubleshooting. Don't Rate my answer until you are satisfied.

Customer: replied 2 years ago.
I followed your instructions and now both screens are stuck on white. It has been happening regularly recently and sometimes I had to boot in safe mode then in normal mode. I don't know why this happens but do not think that it's related with the superdrive problem. I'll now try safe mode
Expert:  Ashik replied 2 years ago.
Before trying Safe Mode, try Disk Utility.

  • Turn off your Mac.
  • Turn in back on and immediately hold down Option at boot and select the “Recovery” disk at the boot menu
  • This will boot your Mac to XXXXX Utilities” menu
  • Select Disk Utility.
  • In Disk Utility, Repair your disk and Repair Permission
Customer: replied 2 years ago.
Sorry I am already in safe mode. The optical drives' behaviour has not changed. Shall I follow your latest instructions now?
Expert:  Ashik replied 2 years ago.
Yes, please try it
Customer: replied 2 years ago.
All done. Disk and permissions were OK. Rebooted. Still ejects my disks.
Expert:  Ashik replied 2 years ago.
We can reset the System Management Controller and see if it works or not.

  1. Shut down the computer.
  2. Unplug the computer's power cord.
  3. Wait fifteen seconds.
  4. Attach the computer's power cord.
  5. Wait five seconds, then press the power button to turn on the computer.

 

Does that works ?

Customer: replied 2 years ago.
All done, no change. If I click any of the 2 greyed out SuperDrives in Disk Utility the right window shows: To erase a rewritable CD or DVD so that you can write to it again:
1. Choose how to erase it ... etc

Is all this normal?
Expert:  Ashik replied 2 years ago.
Your Mac doesn't recognize the discs. Do you have the Mac OS X installation discs came with your Mac ?
Customer: replied 2 years ago.
Yes but I bought it in 2008. It must be Leopard. Now I have Mountain Lion on.
Expert:  Ashik replied 2 years ago.
You can try to boot into the disc. Put the disc 1 to your Mac and turn off your Mac. Turn it back on and immediately hold down C key on your Keyboard. Keep the key held down until it boot into the disc. Does it boots into the disc ?
Customer: replied 2 years ago.
No. It ejected the disk twice during rebooting.
Expert:  Ashik replied 2 years ago.
Then it must be related to hardware. Can you reinstall your Moutain Lion OS X ? That is the only option I could think of now as we already tried all troubleshooting steps so far.
Customer: replied 2 years ago.
I only installed a few weeks ago when it was released. Why do you think that going through this again should have an effect now?
Expert:  Ashik replied 2 years ago.
If it is software related, then reinstalling will fix it. Do you had this problem before upgrading to 10.8 ?
Customer: replied 2 years ago.
Long before. Furthermore, would a hardware problem affect DVS's and not CD's?
Expert:  Ashik replied 2 years ago.
There are two different lens on a drive, one for DVD and one for CD. This usually happens if the lens of DVD is failed. But it is very STRANGE that it happens on both drives. Can you make sure all the connections to the drive are fine on your Mac Pro ?
Customer: replied 2 years ago.
How? Should I open it? I haven't for at least a year. Would a connection be partially undone on both drives?
Expert:  Ashik replied 2 years ago.
Yes, open it up. It is possible to have connection problem. If you are not comfortable doing that, then it'd be better to take it to the Apple Store.
Customer: replied 2 years ago.
OK I'll do it now
Expert:  Ashik replied 2 years ago.
Good Luck :)
Customer: replied 2 years ago.
All done. I gave it a good dusting too. The connections were fine. I pulled them out and put them back in and they felt quite firm.
Still ejects the tray when I put a DVD in.
Expert:  Ashik replied 2 years ago.
I'm Sorry, but it seems more like a hardware problem, something we can't fix online. You will have to take it to the Apple Store. We've all tried everything. Sorry I couldn't solve your problem..
Customer: replied 2 years ago.
OK, thanks for trying.

  • Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill Bill M. Schenectady, New York
