Burned DVDs won't mount/read but seen by Disk Utility as containing data

Hi,
I've got a problem. I have about 200 burned DVDs which were created using my LG VHS/DVD recorder/player. I have used these same DVDs to burn from my external LaCie DVD buner with my PPC G5 running Tiger and my LG Blu-Ray burning with my MacBook running Leopard and those burns plays fine on all 3 devices. However, neither the LaCie DVD burner nor the LG Blu-Ray burner seem able to read/mount the DVDs created with the LG VHS/DVD recorder/player although the G5 and the MacBook, both using Disk Utility, can see that there is data and the size of it on each disk. I am also unable to create a disk image for some reason as it begins but halts saying there's an I/O error. I need to get the content of these disks onto Hard Drives to rip and encode. How do I get the computers to mount these disks which they clearly see are not blank?
Thank you

Try opening them with mpegStreamclip:
http://www.squared5.com/svideo/mpeg-streamclip-mac.html
which is free, but you may also need the Apple mpeg2 plugin :

which is a mere $20.
You should be able to convert them to mpeg2 which is the standard format of a video DVD.

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:

Give us more info. on youe system and media used for more detailed help.

Exernal drive won't mount but seen in disk utility

2011 Macbook Pro 2.3Ghz 8Gb on OSX 10.7.2 connected Maxtor One Touch 4 750Ghz firewire drive. Has been working perfectly for 3 years.
I'm runnign Pro Tools 9. I had some issues with IK Multimedia plug-ins being de-authorized earlier today. IK suggested repairing disk permissions (which I did). Seemed to be OK, but a few hours later when I booted up the MBP it no longer recognises the drive. The drive is booting up & I've swapped out the cables, so I can rule them out.
The drive was called "PT drive". It had 3 partitions: "Rough bounces", "Samples & loops" and "PT Session drive". Now, it doesn't appear on the desktop and Pro Tools can't see it.
However, disk utility sees the drive as "750Gb Maxtor" with 3 partions: "disk1s1", "disk 1s2" and "disk1s3". All of the disk utility options are greyed out (Verify disk permissons, repair disk permissions, verify disk and reair disk) so I can't do anything with them. When I try to eject the disk, I get an error message saying the drive can;t be ejected because applications are in use. I don;t have anything running in the background.
I don't have a backup for this drive, so really need to get the problem sorted urgently. Any help greatly appreciated.
Thanks in advance.

Re-booted everything up again this morning & the extral drive has appreared again. Very strange. I've created a back up drive in case I have similar probs in the future. A lucky escape!

WD Passport not mounted and not seen in Disk Utility, but something seen in Terminal

Hi,
I have a WD 1TB Passport external hard drive. THe light comes on and the disc spins, but I can't see the hard drive in disk utilitiy or anywhere else. I know that it connects. I saw a post about using terminal to mount using code, but it never found the drive. I opened Console and removed and then plugged in teh drive again and what it says is the following:
kernel:USBMSC identifier (non-unique): 0F06CB9C0F06CCCA 0x1058 0x0 0x1015, 3
I have no idea what this means. Please help me try to find my external drive again.
Thank you.

If you have another non WD enclosuer, swap into that one and see if it is now detected in Disk Utility.
Contact WD technical support for assistance.
Ciao.

External HD Won't Mount, Only Shows up in Disk Utility

My external Time Machine drive won't mount any more. It seems like it's very sensitive to being disconnected
without putting it in the trash, and my USB interface seems to spontaneously disconnect -- possibly loose.
The drive shows up in HD Utility with the mounted name greyed out, but it can still be selected to try a repair.
It always says it cannot repair the disk and to back it up. Well, it IS a backup. Disk Utility does seem to give up
on repairs quite frequently anyway. I've tried df -hl and then fsck_hd, but df -hl doesn't give me a /dev name that
fsck_hd can use.
I've gotten into terminal and been able to look at some backups, so apparently something is mounted, just not completely
to the point of seeing it on my desktop.
Is there a way to moving these backups to another drive? Perhaps via an OSX-specific darwin *nix command for copying
an entire directory in Terminal?
Is there an app that's particularly good at disk recovery other than Disk Warrior (which tends to take days to work)?

Have you tried another USB cable?
Also, you may need to take the drive out of that enclosure and use a different one.

How can I force mount a dvd that isn't even seen by Disk Utility? I can see it on the Mac when using my Windows 7 partition via Boot Camp, but not in Lion, which is how I would rather be running.

Well if there is a EFI block, then running a program in OS X isn't going to do a lick of good.
After all EFI was designed for Trusted Computing and Digital Rights Management, to act between the OS and hardware, can read drives, contact the Internet and everything.
Windows doesn't use EFI, will have UEFI in Windows 8 though.

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.

Up and running with Snow Leopard now and working on the updates.

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?

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.

Burned DVD works on PPC Macs, but not Intel

We have two identical copies of a burned DVD. When we insert it into one of the two intel Macs we have (MacPros), it spits them back out or gives read/write errors. When we put the DVD into either of the two PPC macs we have, they mount without issue.
Booting to an external gives the same error, so it's not a software issue it seems.
Has anyone else seen this before? Thank you for any help!

Are these just data discs? Or are you trying to use them for booting the computers? If it is the latter, Intel boot discs cannot boot PPC and vice versa. If it is the former, it's definitely a bizarre sounding problem. Unless, of course, when you say "when we instert it into one of the two intel Macs.." you literally mean only one of the Mac Pro's gives you problems then it's probably just a faulty drive. But if both give you problems, well, then it's still a bizarre problem.
Try feeding us with more details. OS versions, disc types/formats/contents, DVD-R drive models, whatever you can think of to help us help you.

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?

Blank DVDs won't mount

My iMac mounts DVDs containing content, but ejects blank DVDs without mounting them. Same problem with CDs.I reset the PRAM, but this did not cure the problem. Anyone have any other suggestions? Does my iMac need repair?

You need to check what DVDs your player/recorder can handle.
Go to the System (apple) menu and choose ‘About this Mac’ then click on the ‘More Info...’ button.
In the contents column of System Profiler choose ‘Disc Burning.’
Now look at CD-Write and DVD-Write and Write Strategies in the right hand pane. These are the types of media you can use. Many iMac G4 units could read, but not write DVDs.
If your iMac can write to CD/DVD, you are using the proper media format, and your drive STILL will not burn, then the burn lasers may be malfunctioning or dirty. Try using a CD/DVD cleaner (actually, a spinning brush) to clear off dust and dirt. If that won’t work, then you probably need to replace the drive.

Burns DVDs, WON'T play commercial DVDs

So I seem to be having the REVERSE problem from everyone else. My iMac G4 (17", 1GHz processor, 512 MB RAM), which I just bought for a piddling $200, will play and burn CDs / CD-RWs just fine. It will also correctly identify blank DVDs that I stick in the drive. It will BURN DVDs. In a few hours, I'll be able to tell you if it will read data DVDs.
The ONLY THING it won't do is play COMMERCIAL DVDs. I pop in a video DVD, it spins up, tries to read it, then spits it back out. Now, I know the not playing DVDs problem is not a unique one, but in reading on these forums, that seems to always be a symptom of the DVD laser diode having gone bad, which is certainly NOT the case here (as it's merrily burning away).
My GUESS would be that--somehow--my installation is missing the CSS library necessary to decode commercial DVDs. I had a similar problem getting my iPod Touch to talk to iTunes. But is that even possible? And, if so, how do I go about rectifying this issue?
Any help would be greatly appreciated.

I FIXED IT!!!!!!
I read somewhere else on this forum about someone having a similar problem to mine. He took the iMac to a service depot, but when he got it there, they couldn't replicate the problem. He took it home, and HE couldn't replicate the problem. As in, it was now fixed. Turns out that just unplugging the unit gave the Superdrive a chance to "reset."
So I unplug my iMac to test this out, as well as to see if I can unscrew the access panel to determine how easy it'd be to upgrade its RAM. Well, I could only get one of the screws out, but when I plugged it back in, turned it back on and popped in the collector's edition of "2001: A Space Odyssey," DVD Player came up and began playing the disc! Never has "Thus Sprach Zarathustra" sounded so amazing!
So, thank you, John Westwood1! Thank you!

CDs/DVDs won't mount

Neither will mount after insertion into drive. In order to mount them, I have to use Disk Utility. I've repaired permissions which didn't affect this at all.
Is this just a dirty drive of some kind of software problem or hardware failure?

Hi holgaguy, it appears you have a Rev A Imac and resetting the SMU will sometimes correct hardware issues. I would try that first if you feel comfortable removing the back of your Imac. Then just read this link, alot of it won't apply to your exact problem but will show you how to reset the SMU. Seen as they will work through disk utilities I would guess the the drives are not pooched. Post back with the result and we can go from there. Bob :~))
