Mac Mini won't start and constantly makes disc ejecting noise

My Mac Mini won't start. It was working fine, then just locked up and won't start again. When I push the start button it just makes this repeated disc ejecting noise from the DVD drive. It doesn't make the chime noise or display anything on the monitor. I've disconnected the optical drive, but it didn't help. Then it just doesn't start at all. I thought that if I would disconnect the optical drive, that it would ignore it and just boot off the hard drive, but nothing happened. The power light comes on. Then, if I hold down the power button for 10 seconds it shuts down. The fan operates. It just never attempts to boot up. I can't put in a system DVD because the optical drive is just in eternal eject mode.
If you have any suggestions let me know. Thanks.

I have the same situation.
I think the drive thinks it has a disc to eject or part of the mechanism is stuck and can't return to it's resting position. I was going to disconnect as you tried but now I think I'll try to disassemble the drive to see if there might be some debris jamming things up.
Please let me know if you solve the problem.

How do I fix iMac that automatically ejects disks without reading them

How do I fix an iMac that automatically ejects disks without reading them?
Have tried resetting the SMC, didn't work.
If I have to get a new drive, how much do they cost on an iMac and where do I get it fixed?
Very disappointed if we have to spend money to fix computer as we have not had this computer for a very long time and we bought a Mac because it was supposed to be better.

Have you done a PRAM reset, CMD+Option+p+r...

In fact, do 3 in a row, takes a bit of time.
Also might try one of those cleaning CDs.
Replacing it isn't very easy, but...

Frequent ejecting noise all the time..

I have a Macbook 10.4.11 OSX and it is 2006. It is a bit old,as I bought it from ebay.
It makes the ejecting noise every time I open it, turn it on or even touch it sometimes. It is that noise when you eject a disk.. I realized that if I press the area above the disk area, it will make that noise again.. and sometimes it just keeps repeating.
Is this a normal thing? It does it quite often and not very good when I am in a quiet class and it happens randomly. I don't have a warrenty, so that is why I am asking on this site. Any ideas?
thanks!

Hi MariaLav, and a warm welcome to the forums!
What happens if there is a CD in it when that happens, does it eject?
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, test if it makes that noise sleeping from Safe Mode, reboot when it completes.

Ejecting noise when I opened laptop lid?

When I opened my lap top this morning, the DVD/CD drive made an ejecting noise but there was no disk in there. Never happened before…just wondered why this would be and if/what I should do about it?
MacBook Pro 10.8.5

Usually when you boot up a Mac with a built in drive you will hear a brief sound as it checks whether there is a disk there it needs to mount, so that is most probably what it happening.

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive. Can't get it to run Hardware Test. Disk Utility says disk OK - files are there. What can I do?

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard. I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host. But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning. I can't get it to run Hardware Test - just get the white screen. If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

Reet the SMC and the PRAM
 Cheat sheet to help diagnose and fix your Mac
Perhaps you installed the wrong version OS X onto the iMac, you can't use the disk from another Mac.
clean the disk.
If it's not working then use this method to create a bootable 10.6 USB from the iMac machine specific 10.6 disk or the 10.6.3 retail disk on your other Mac, use it to boot the iMac with.

My macbook pro makes that ejecting noise when i open it but not every time usually when i ve been away for awhile then take it out of sleep it makes the noise is this normal?

Hi ive had my macbook pro for a week or so and when i open after its been in sleep mode for quite a while it will usually make that ejecting noise. It doesnt make the ejecting noise evreytime i open it just sometimes. Is this normal HELP

Yes, it's normal.
Apple released a firmware update a couple of years ago that was supposed to stop the drive from making that noise in certain models that were available then, but even the update didn't work all the time. The noise is completely harmless and not indicative of any problem. Just ignore it.

My iMac is starting with a safe boot

Why is my iMac starting up with a safe boot?

This might stop it booting in Safe Mode. Open Terminal in Utilities and copy/paste only
sudo nvram boot-args=""
Hit return and enter your admin pword when requested. You won't see anything entered as you type it in. Then hit return again.
(Note: I've never had this happen, so don't know if this is effective or not. Found it in another thread here for this problem. If it doesn't help, it should at least be harmless. Maybe Linc can say; he's far more Unix literate than I. OK, found where it came from:
https://discussions.apple.com/thread/3965882?start=0&tstart=0)
So looks like either a PRAM Reset or the Terminal command will work.

Late 2009 Mac Mini odd Super Drive Loading and Ejecting Noise

I have had no problems with my Mac Mini until now. Just today I inserted a disk into the super drive and it made a different noise to usual as it took the disk. Also, when I ejected it, it made different noise to what it usually makes. The drive still reads and writes fine it is just the loading and ejecting noise I am worried about.
Help would me much appreciated

Sounds like you should be expecting the drive to fail more or less any time now. If the thing is still under warranty, take it in and try to get it replaced. There is a category for abnormal noise when selecting the failure type, so you should have a decent chance. But only if it's under warranty.

IMac 2.4GHz (MA877LL) refuses to boot with 4GB ram, boots only with 3 GB

iMac 2.4GHz Core 2 Duo 20" Anodized Aluminum (MA877LL)
iMac 2.4GHz (MA877LL) refuses to boot with 4GB ram, boots only with 3 GB
2 x2GB Geil GX2S6400-4GDCA
Computer refuses to boot with both chips installed 4 GB.
Computer will boot and recognize 3 GB..( Apple 1 GB + 2 GB GEIL)
Both Geil Chips will boot, when paired with the Apple 1 GB chip.
machine recognizes 3 GB ram.
Please advise...

Ensure the computer's RAM is fully seated down, and then try resetting the PRAM by holding down options-command-P-R at boot. The computer will make the boot chimes and then reset and chime again. When it chimes the second time release the keys and let the thing boot normally. Hopefully that will let it recognize the RAM.

My IMac just started making noise like a disc is running (there is no disc in it) . Is that normal?

Probably the fans running.
Make sure the air vents are clear.

Imac will not eject cd

The CD drive in my iMac will not eject CDs. I often have to shut down the iMac and re-straert it several times before I can get it to eject CDs. Help!

It may need cleaning or may be warn out. Get a cleaning kit and try that first.

My home imac has crashed and will not boot up.

Hi
My home imac has crashed and will not boot up and I'm not sure where to start.
It wouldn't shut down properly so I turned off the power, and now it won't go beyond the apple logo and timeer when I try to restart it.
It is an imac (4 years old), Intel, running OS X, not sure which version, but probably the latest.
Thanks
Carol

I would first reset the SMC:
Shut down and unplug the Mac.
Keep the Mac unplugged for at least fifteen seconds.
Plug the Mac back in and do not turn it back on for at least five seconds.
Press the power button to turn the Mac back on.
Then I would reset the PRAM by rebooting the iMac while simultaneously holding the Command-Option-P-R keys until the machine restarts a second time.
Let us know if these two procedures don't solve the problems.
Hope this helps
