DVD won't mount in Finder

I'm running Mac OS 10.5.2. When I put in a DVD, and ask that it mount in finder, I get the message ""the operation could not be completed because you do not have enough access privileges" I have two superdrives. The problem occurs with both. I have called apple tech support.
I have tried the following:
1. Repaired privileges ("ACL found but not expected in "Library") and repaired disk (no errors)
2. Logged out and tried another account- same problem.
3. Installed Leopard on a clean partition. DVD Mounts on clean install. Then ran Migration Assistant. After migrating my software and prefs., the problem reoccurs.
5. Restarted Finder
6. Tried DVD in another Computer. It mounts in finder w/o problems.
7. Zapped PRAM
8. Googled til my fingers bled.
9. Pounded on my motherboard vigorously with a ball-peen hammer. Well, OK, I didn't do that, but I'm getting tempted... :o)
This is obviously a corrupted file somewhere. I really REALLY don't want to do a clean install and then reinstall all my software.
Anyone got any ideas?
Thanks,
RP

There may be a permissions issue with your home folder, which transferred to the new partition when you migrated. Repairing hard disk permissions with Disk Utility doesn't repair the Home folder. Start the Mac with the Leopard install disc and go to Utilities → Reset Password → Reset user permissions to default. Leopard Cache Cleaner also can repair home folder permissions.

DVDs won't mount - discs ejecting

(Inadvertently posted to aluminum forum -- this belongs here.)
Searched and did not find exactly this problem in prior posts.
CDs still mount and play fine, but now all DVDs won't mount and are automatically ejected. I've looked previously at region settings, decided not to change, now can't even find region settings to verify I'm still set to 1. I don't really think it's a region problem though, as I'm pretty sure I didn't even try to change regions.
Any suggestions? Thanks.

Not quite sure what's wrong here, but let's see what System Profiler (Applications>Utilities) has to say about your drive.
Open up System Profiler, then click "Disc burning" in the left-hand column. Next to "Reads DVD" what does it say?

Can't install Snow Leopard on MacBook Pro - DVD won't mount

I am unable to install Snow Leopard on my MacBook Pro as the DVD won't mount. This is an early 2008 vintage MacBook Pro, intel core duo...
I'm using a OS X Snow Leopard install DVD (family licensed). This DVD has been used to install 3 other Macs in my house without a problem (about a year ago), but cannot be used to upgrade my MBP. Actually, this disk mounted on the MBP exactly once - inserted with system up, the disk mounted. Upon running the installed (a year ago), the computer restarted but hung in boot. After getting the disk ejected and the computer restarted, the disk would never mount again. I've defered upgrade for a year but at this point need to upgrade my MBP at least to Snow Leopard and possibly Lion.
The problem doesn't seem to be with the DVD, since it continues to mount fine in other computers, and in fact a borrowed Snow Leopard DVD also will not mount on the MBP.
BUT ... the problem also does not seem to be with the optical drive in my computer, as it can read & mount the install/restore disks that came with the computer as well as other CDs and DVD ROMs. Only the Snow Leopard install DVDs fail to mount.
I've also tried mounting the 10.6 install DVD on my Mac Pro desktop, making it available over the network (ethernet) with DVD/CD sharing. I can mount the remote disk from my MBP that way, but when I launch the installer, the application launches (its own menus are displayed, I can quit from menu, for example) but does nothing -- no windows open, nothing.
I've also tried "Remote Install" (again with the DVD made available with the Remote Install MacOS X application on my desktop), but when I boot the MBP with option held down, the remote disk is not available as a startup disk.
Zapping the PRAM did not help.
Am off to the store to get an optical drive cleaning kit and a blank DVD big enough to burn a new disk image, but would appreciate any further ideas at this point....

Solution that worked: Copy the Install DVD to a USB flash drive and boot from that.

DVDs won't mount after Security Update 2006-004

DVDs won't mount after installing Security Update 2006-004 via the Software Updater in OS 10.3.9. CDs work OK.
I've repaired permissions, reset PRAM, tried booting in OS 9.2.2 but can't get the DVDs to mount/play or be seen by disk utility.
Please help.
iMac 400mhz
Original Matshita DVD-ROM SR-8184
iMac Firmware 4.1.9
Thanks

How recently before installing the Security Update did you use the DVD drive (for DVDs)? If it was not immediately before the update, the two are probably not related. Also, if you restarted in Mac OS 9 and the DVD drive still does not work, it would seem to indicate the problem is hardware, not software.
You can try opening up the iMac and checking the connections to the DVD drive. Also, it is possible that your PRAM battery is dying (unless you have replaced it recently); that can cause unexpected problems.

DVD won't mount (again !)

This topic has been on a few times, but none of the aswers worked for me.
I have a powerbook 1,66GHz Al that won't mount a DVD-R (noise for about 15s and eject without any messages). The same DVD mount and play correctly on an ibook 1.2 GHz under 10.4.4.
My preferences are : ask me what to do for new CD/DVD. For when inserting a DVD, I tried DVD player and VLC with the same result.
I installed Tiger from scratch and did not reinstall yet any iphoto, idvd, ilife...
I'm just wondering if this is the reason that I cannot read these DVD.
Any idea ?
Bernard

I did not realise that CDs had to be finalized before use in other machines.

DVD won't mount on OS X Mavericks

I have some movies that I want to watch on my computer, I have a Macbook Pro (2009) with OS X Mavericks installed. I've been successful in mounting and watching some older DVD's, but these new DVD's I have won't mount, is there some sort of work around or something that new DVD's have that won't let them mount? Or is this with OS X Mavericks and some protection device?
Thanks

Anyone have any ideas or thoughts on this? Thanks!

External RAID0 won't mount in Finder or Disk Utility

Hi everyone,
Thanks in advance for any help you can provide.
I have a Western Digital Passport RAID0 that I connect to my 2008 Mac Pro via Firewire 800. It has worked for years. I switched out one of the drives about a year ago after it went bad, but when I did that, Disk Utility was still able to see the two separate drives when plugging it in the first time after switching them out.
This time, when the RAID0 wouldn't mount in Finder, I opened up Disk Utility and neither drive showed up. So I opened up the enclosure and tested both drives in a USB dock. One mounted fine, the other said it was unreadable. So I set the unreadable one aside and switched it out with a same-size replacement drive that I had partitioned as MacOS Extended Journaled (non-case sensitive) with GUID partition table (same as the other drive and all drives on my system).
Reassembled the enclosure and plugged it back in. Still, neither drive is recognizable by Finder or Disk Utility. Verified it has power and that the cables are seated correctly. I also tried USB connection just to be safe.
I do not believe the RAID controller in the enclosure is bad—at least it seems very illogical that a drive and the controller would fail at the same time, as I have it well protected against power surges.
Any thoughts as to something I may be missing or known issues? I upgraded to Yosemite at its public release but successfully used the drive between then and now.
Thanks again!

Eric, nifflerX and nbar:
That's what I was afraid of.
Thanks for your help.

Burned DVDs Won't Mount

Recently after burning DVDs - via DiskUtility and iDVD - burned DVDs will not mount: Instead after inserting and waiting the DVD simply is spit back out. Yes, I've run Disk Warrior; did fsck -y; Onyx.
What can I do now?

woodrackets
It miight be the DVD disks. If they are newer high spead the iMac'ssmart drive may not like them. Have you updated the drives firmware?
If it's a 15" iMac see:

Bootpartition won't mount, fsck finds no errors

Hi guys,
got a strange situation here. My Bootpartition /dev/sda2 won't mount in Arch anymore.
mount /dev/sda2:
mount: wrong fs type, bad option, bad superblock on /dev/sda2,
missing codepage or helper program, or other error
Manchmal liefert das Syslog wertvolle Informationen – versuchen
Sie dmesg | tail oder so
The same error appers during boot. I don't know how Arch can boot without bootpartition but ist does...
Another strange thing is that it mounts fine in Mandriva running on the same machine. Also testdisk under Windows didn't complain.
dmesg | tail
EXT2-fs (sda2): error: corrupt root inode, run e2fsc
e2fsck /dev/sda2
e2fsck 1.41.14 (22-Dec-2010)
archboot: sauber, 43/36288 Dateien, 33179/144584 Blöcke
grep -i archboot /etc/fstab
LABEL=archboot /boot ext2 defaults 0 1
file -s /dev/sda2
/dev/sda2: Linux rev 1.0 ext2 filesystem data, UUID=c477713e-ff47-40f3-92f0-537291f24937, volume name "archboot
So what now? Any help is appreciated.

no changes to any partitions were made, just did a fatal "pacman -Syu"...
i removed the /boot completely from fstab and tried to mount the partition manually.
i also recreated the whole partition under ubuntu. copied the files out, deleted the entire partition, recreated it and copied the files back.
arch linux still can't mount it.
also when i'm trying to mount my jfs partition, the "mount" command hangs completely. even "kill -SIGKILL $pid" can't get rid of it.
the jfs partition also mounts fine under ubuntu, i ran tests on every partition under ubuntu, they're all clean.
mounting an jfs partition don't give any logfile entry, dmesg is also empty. it's just hanging. the funny thing is, that ext4 and vfat partitions are mounting fine.
could something be wrong with hal or dbus?
here's e2fsck output:
e2fsck -pvf /dev/sda8
35 inodes used (0.15%)
4 non-contiguous files (11.4%)
0 non-contiguous directories (0.0%)

22 regular files
4 directories
0 character device files
0 block device files
0 fifos
0 links
0 symbolic links (0 fast symbolic links)
0 sockets
26 files
--------EDIT:
finally found it!
for some reason (i don't know why) the /boot partition was not mounted during update and thus the kernel26 image was written into the /boot directory of the root partition instead of the /boot partition (where it belongs). this means on next bootup the system was booting with the older kernel but the updated system. maybe some things in filesystem handling were changed between the two versions of the kernel.
i mounted the arch partitions within ubuntu and copied the files from the /boot directory to the partition which should be mounted in /boot on startup.
everything's working now.

G5 1.8 DVD Won't Mount/Startup

Hi folks.
My trusty (yet dead slow LOL) G5 1.8 won't load any DVDs. I am trying to install either Tiger or 10.2.7 (the startup DVD that came with it) and not a single DVD won't load, including other DVDs.
I insert it, it spins, tries tries tries, then spits it out, giving me no feedback. Tried starting up using C during reboot, and the same spit-out.
Any idea what I can do? I don't see it as a current OS issue, but more of a DVD player issue.
Model: SONY DVD RW DW-U10A
Revision: A43h
Serial Number: EA48866F
Detachable Drive: No
Protocol: ATAPI
Unit Number: 0
Socket Type: Internal
Cheers

It very likely means your DVD drive is dead. Many only last 5 years, but that's no guarantee. You can try using a lens cleaner disc (buy in a media store - often used for home CD players) but that's no guarantee unless you're lucky and it's simply a bit of dust. Will it play a CD? CDs aren't as finicky as DVDs.
With a tower model it shouldn't be too difficult to replace it yourself for US$40 or less.
In the past Pioneer drives have been a safe bet (e.g., from [OWC|http://eshop.macsales.com/item/Pioneer/DVR116DBK> or [Newegg|http://www.newegg.com/Product/Product.aspx?Item=N82E16827129023]). However, check [Jeff's January 2010 post about re-branded Pioneer drives|http://discussions.apple.com/message.jspa?messageID=10839236#10839236] that are no longer really Pioneer manufactured.

DVD won't mount in 10.6.2 - possible bug?

I'm sorry if this seems like a cross-post but I believe I've narrowed my problem to SL 10.6.2 and don't know where else to post this.
DVD will play in standalone DVD player but NOT mount on the computer that created it. I have confirmed that it will mount and play on a bootable backup I had made (10.5.8) before upgrading to Snow Leopard. Another reader posted the same problem on the thread.
please take a look and tell me what you think...
http://discussions.apple.com/thread.jspa?threadID=2260033&tstart=0
thanks so much,
Pale

The DVD will also mount in 10.6.1 (I had a bootable clone of that installation, as well)
to recap...
I created an iDVD project. Saved as an .img file. Burned to DVD.
Those DVD's will not mount on the computer and OS it was created on.
They will mount on the same computer booted into clones of 10.5.8 and 10.6.1
They will play in standalone DVD players
They will mount on a friends Tiger installation 10.4.9

DVD won't mount or eject, won't shut down.

My Mac Pro won't mount or eject an older optical disc in my OWC BD drive installed in the lower optical drive position. I've tried all suggestions. It also won't complete shutdown. It gets to the grey screen and gets stuck. Have verified and repaired my System drive, have tried using the terminal as suggested here: https://discussions.apple.com/message/16582744?searchText=disc%20won't%20eject#1 6582744, which opens the top drive. Is there a command for opening the secondary tray? Have also reset my SMC. I've read other threads about people with discs not mounting or ejecting and preventing shutdown, but all seem to be in the primary optical drive. Any help apppreciated.

I finally opened the tower, accessed the drive and ejected the disc with a paper clip. Now everything works again.

SuperDrive is ejecting all DVDs, won't mount

I purchased a few movies over the holidays. I put one into the SuperDrive and it spins, hums, and sounds like its scratching. Shortly thereafter the SD ejects the DVD. I've restarted my computer and tried again and now it won't even try to mount. It just rejects the dics. Purchased and burned CD media is fine.
Issue occurs when:
1. Commercial DVD is inserted
2. Leopard install DVD is inserted
3. Burned home movie on DVD-R media is inserted

Is there really no other solution? I have the exact same problem with my older iMac and it drives me crazy. I've been all over the internet searching for a solution. None of these have worked for me, but they have for other people and so maybe they could for your case.
Repair disk permissions in Apps/Utilities/Disk Utility and then restart
Verify disk for any problems and if there are then use your system disk to fix it or /sbin/fsck
One person said that they relaunched their finder to solve their problem
Maybe it could be fixed with a CD lens cleaner or blowing the dust out of the disc drive
I think it is most likely a software problem if CDs work, but then I'd like to fix it rather than a replace and old, but working drive.
Does anybody else know of any possible ways to fix this?

DVDs won't mount

This is asked repeatedly in the hardware forum, but never answered, so I'll try here.
I am no longer a happy camper.
Some DVDs do mount, some don't. There is no rhyme or reason to it. I can purchase a complete box set of "The Complete Five Seasons of __________", and some will mount, some will not. Same with rental DVDs, or DVDs I've burned myself on my iMac. All the commercial DVDs, and most of the DVDs I burned myself, work fine on my cheapo set-top t.v. DVD player.
Doesn't matter if they are brand new commercial DVDs, or if I clean the rented DVDs. So luck repairing permissions, running CacheOutX, Onyx, DiscWarrior, shutting down for 15 minutes, or anything else. Nor do the DVD lens cleaners help -- most of the time they won't even mount.
Any ideas?
Are there any external DVD players that I could plug into my iMac via Firewire?

You are posting in the wrong forum. This forum is about iDVD the application from Apple. This forum is NOT about general DVD issues and questions.
Try searching for the forum for your specific computer. Most of the computer forums have a DVD/Optical Drive forum where your question would be more appriate.

Trying to install Tiger, DVD won't mount

I just bought the upgrade for Tiger. They sent it out on DVD. Fine, no problem I thought because I have a Sony DVD RW DW-U10A the so-called SuperDrive that reads DVD's.
I can get a data and audio CD to mount up with no problems. I can't get any DVD to. It inserts but ejects after about 15 to 30 seconds. I can here it kind of clicking around, but not the big windy spin up that the CD has. Is there a reason why a CD would mount, but not a DVD? I've read everything I can since yesterday around 1:30 and while there seems to be a LOT of us with the same/similar issue, I don't see any 'AHA this fixed it' answers. Is it a bad drive?
I've tried booting up holding the C. I've reset the PRAM and VPRAM. I thought I'd be creative and inserted the DVD in my PC to share it across the network but the PC wouldn't read it either.
Any ideas? If it's bad and so many people have issues, why didn't it get recalled? Why isn't Apple addressing the issue? I see nothing in the tech articles that addresses the problem even though there are many, many posts here on the forum.
Is purchasing a new DVD drive the only option? That hardly seems ideal when I've spent my extra budget on the OS upgrade. I didn't budget for required new hardware.
Any help would be MOST appreciated. I was so excited about the upgrade...and now after all this time, I'm just depressed and frustrated.

I can try that. I called the 'local' Apple store in my area and they suggested replacing the driver. That would be fine and good, however the original iMac disks are also DVD's.
Where else could I find that driver to reinstall? I purchased the Apple Care at the same time as the computer and never used it. I installed the Tech Tool and am running the diagnostics, but so far everything appears fine.
Does someone have that driver or can lead me to a location that has it so I can reinstall and see if that helps?
