Strange DVD Mounting Issue

I am still able to burn DVD-R media, through Backup 3.1 and several other software packages that automatically recognize a disc in the drive and burn it. I cannot however see the blank disc on my desktop and create a burn folder to burn a disc manually. It appears in the Disk Utility, but I am unable to "mount" it and it claims the disc is locked and can't be written to. I should still be able to see it on my desktop, no? It is possible this started after the latest system update that I just installed. Any advice on this?
Thanks.

I think it's the disk. The fact that there are instructions regarding mounting issues specific to macs would tell me that they have had in the past problem complaints. Try it in your dvd player on your TV. Get another copy from the store and also get a copy of something else not Disney to see if that plays.

DVD mounting issue with new Pirates of Caribbean: at world's end DVD!

So I just picked up the new Pirates of Caribbean: at world's end DVD and was going to watch it on my MacBook (see specs below). and the DVD went in, the drive spun up a few times then ejected the disk. What's up? no error message or nothing. The Disney DVD support page says: "+If you have problems loading a DVD on a Mac, hold down the Command, Option, and I keys when inserting the disc. (This mounts the disc using ISO 9660 instead of UDF.)+" This must just be a Mac OS 9 shortcut (in OS X it just launches a "get info" box - same as Command i). It also says I might not have updated drivers, etc. But can it really be a driver issue?
any thoughts? ideas? help out there?
Thanks!

USB 2.0 Mass Storage Device mounting issues and cannot write data on it

I have a 250 GB external Simpletech Hard Drive (with a USB 2.0 interface). It works flawlessly in a Windows XP environment (strange!!). But when I connect it to my iMac thru the USB port 2 things happen:
1. Sometimes it mounts, sometimes it does not. It's just capricious. If I boot the system with the USB device attached it mounts. If I connect it "hot", sometimes it does, sometimes it doesn't. Sometimes it does not appear as mounted...I disconect the device and the Mac gets angry.
2. I can read all the data on the disk, but I can't write any. That is, I cannot use it for backing up any iMac data. The backup utility won't recognize the device either.
I've seen people going thru the mounting issue (not sure if there is a solution), but I am puzzled about the inability to write data on the hard drive. I am wondering if this is due to a formatting incopatibility? Any hints??
iMac Mac OS X (10.4.10) 2.33 GHz, 2GB, 750 GB

For both the Mac and a Windows PC, format it as 'MS-DOS'.
Both platforms can read/write to it. A Windows PC is not capable of reading/writing to a Mac formatted (HFS, HFS+) disk without additional software.
MacFixit has been covering some apparent USB issues which may or may not help you. http://www.macfixit.com/
I'm still at a loss. I have yet to experience or reproduce the USB issues that a number of users seem to be having. Now that I have sufficient free time, I may look into it.

I still have Cd/DVD drive issues

The CD is ejected after a short while and never mounted. I have cleaned the optics of the CD drive and reset my PRAM.
Has anybody discovered a complete solution for this problem.

That's good that it is in device manager, but what about in Computer with the rest of the drivers?
Also, are the drives listed in Computer and device manager or just device manager?
I want to verify if the symptoms are present for a particular software issue before looking at other issues. I really doubt it is a driver issue at this point. If it was, then I suspect the issue would be present from day one.
It could be that the lens has dust buildup preventing it from working properly. They do make CD cleaning kits that have a special CD designed to clean the laser as it passes over the lens. If you happen to have one of these, or access to one, I recommend trying this step to make sure it isn't as simple as dust buildup interfering with the laser.
It could also be hardware failure, but I would like to try a few other steps before coming to that conclusion.
It may be worth reviewing this document as it covers a lot of the most common issues behind DVD drive issues. Feel free to skip any steps you have already tried.
Let me know what happens.

DVD mounting is erratic.

I'll take a DVD and load it into the Mac Pro. It makes a few glitchy sounds but won't mount. It won't eject either. I restart and the DVD mounts and works. I can eject it and a day later (or sooner) it doesn't mount again. Any advise? All software is up-to-date.

I am still working on this.
I had Developer tools installed from 10.5. In 10.6.8 I used CHUD tools to access SpindownHD.app to customize when drives would spin down and sleep. I have removed CHUD tools and SpindownHD thinking this may be partially responsible.
I am not convinced that this was the cause although the issue 'seems' to be resolved.
Today after waking from sleep, I opened the System Report window to check two items, Disk Burning and Serial ATA.
Opening Disk Burning I notice a delay before the window is populated.
The same delay occurs for Serial ATA.
When I had the problem of the Superdrive not being recognized, the System Report pane for Disc Burning would never populate (I have drives in both bays).
I am going to let the machine sleep for several hours, wake, open the System report, but not access the Disc burning window, and see if I can duplicate the problem.
I am beginning to wonder if this is an energy saver issue.
I will post my findings.

Satellite 2430 DVD drive issue

Hello there,
my Satellite 2430 has got a strange DVD problem and can't figure out what is all about. All started when I tried to do a full recovery. The unit wasn't able to boot from DVD. I've checked the DVD drive with different bootable disks but still nothing. Unit doesn't want to boot from DVD drive even if F12 is pressed and DVD device selected. Not to mention that the recovery DVD is loaded normally in my desktop pc. The notebook boots up Windows OK from HDD and, what's amaizing is that inside Windows everything is OK. The DVD drive works like a dream. However, this is not enough to perform the full recovery as the recovery process can't be initialised by Windows. Hopping that the BIOS is causing the problem, I upgraded it to version 1.6, but there is no change in DVD's behaviour.
Any thoughts, before using a big-big hammer?

Hi
Did you try to change the boot priority in the BIOS?
If not so change booting procedure to the CD drive firstly. The LAN should be on the end.

ITunes for 64bit Windows 7 Driver/CD/DVD/Drive Issues-

Hi There
I am sure that there are many many users out there suffering the same frustration as me in regard to ITunes just not working properly with Windoews 7 (64Bit).
I have been trying to solve the mystery of "ITunes for Windows Registry Settings Warning When Opening Itunes.
I have tried all the recommended actions to correct this problem without any success and I do mean ALL.
Below is a screen shot of my registry, can anyone see anything wrong with it?
In the meantime (Last four months) I have stopped using ITunes and instead have used Digital 7, this will be my very last attempt to get ITunes working properly, failure will mean consigning ITunes to the same place as any other Software that does not do wshat it says on the can.
I hope someone can help.

That's good that it is in device manager, but what about in Computer with the rest of the drivers?
Also, are the drives listed in Computer and device manager or just device manager?

Third party DVD player issues

Recently, I have come across an issue playing back DVD's with
VLC or XBMC. When I start playback of the DVD, it plays the first
segment ( the studio leader at the beginning) and will then just quit.
Apple's DVD Player works fine (quality is crappy and can't get surround
tracks out of it). Yet, when the DVD is ripped to the hard drive and
played from there, it is works just fine.
Also, this happens when the DVD is played back from an internal
or external drive.
Has anyone else seen this issue or do I have a unique problem?

My unit is a 2010 MacMini with HDMI. (see list)
The quality issues with Apple DVD player vs. other solutions are certain
scenes have a graininess akin to noise on old analog tv's that aren't
present on the other players and severe banding in gradients that
do not appear in other players, at least when they were working.
As far as the audio, selection in the DVD's menu itself just makes no difference.
Tried all the combinations of messing with Audio MIDI setup, third party
plugins like Perian, none of which work for Apple's DVD player. This was
the other reason for going to third party players, the higher quality video
was just a bonus.
Your point has been taken that it may be a software issue with the third party players.
Some update at some point may have broken them, be it OSX or their own.
I've beaten the Apple DVD player issue enough, let's just consider the topic dead.
The audio issues with it are spread over many, many threads across the web, with
no silver bullet solution to all.
As for BluRays, play them back all the time on my Mini. Either with
PowerDVD 10 in a Bootcamp windows7 when I want full DTS-HD or
TRUE HD decoding (decodes these to up to 24 bit,192kHz 7.1 since the
Mini chipset does not have the "protected" path for pass through of
these technologies) or a MakeMKV/XBMC combo in OSX. The OSX
solution doesn't give you the fancy menus and all or HD audio if present,
but if I only want to watch the movies it's fine. If I ever do want the other
nonsense, I just use PowerDVD 10. And please note this is BluRay disk
in player, not "ripped" or transcoded.
I do appreciate your help, but was primarily curious if others had issue
as well.

2.1.2 update does not fix DVD Navigation issues :(

The FrontRow 2.1.2 update still doesn't fix the DVD navigation issues where sub menus on MANY DVDs are not navigable. Using the up / down keys on the keyboard or remote causes the Volume to change and not navigating the menus like it is supposed to.
This is a severe issue as it makes it impossible to play some DVDs or turn on the subtitles.

Yeah, I have experienced this as well. Ridiculous -- how could this issue not have come up in product testing by the time the software has reached version 2.0? The solution on Apple's end should be obvious. All 4 directional buttons must act only as directional commands when using a DVD, and all other functions (such as volume) can only be accessible by hitting MENU first to bring up a list of other options.
I'm all for simplicity, but this is the fault of the boneheaded 6-button Apple Remote. It requires their software to overload buttons with different commands depending on context, which is clearly an unacceptable limitation. They'll have to break down and roll out a proper remote with more discrete buttons one of these days and come to terms with the fact that shoehorning everything onto 6 buttons is not an elegant solution.

Any solution to DVD drive issue post Lion install yet?

Any solution to DVD drive issue post Lion install yet?

Since installing Lion no DVDs are being read by the superdrive, this is a problem that has been highlighted by quite a lot of people.
CDs are being read fine.
After inserting the DVD there is some noise, sounds like it is trying to pickup the DVD then spits it back out.

USB thumb drive mounting issues in Lion?

Hi all,
I just installed Lion on my mid-2010 13" MacBook Pro a couple of days ago. All seemed to be going great until I tried to use my USB thumb drives. I have four of these (3 Sandisk and 1 Imation), and none will mount. When I go into Disk Utility I can see them, but when I try to mount them manually the response is "Mount Failed" and some text regarding running Disk First Aid. However, even when I repair the volume, it still won't mount. This happens with all four drives, and I used them all without incident a few days ago when I still had Snow Leopard installed. They are all formatted for FAT32. I've seen a few scattered messages about USB and NTFS mounting issues, but it appears to be an isolated problem. Anybody else having this issue? If so, are there any workarounds? I'd hate to have to revert back to Snow Leopard just to use my thumb drives.

Try to use the disk utility an format one of your Thumb Drive, and see if it can mount.

Strange Mount Issue

Hi everybody!
Some facts:
After 6 months I decided to upgrade my arch box, so I downloaded 1067Mb all get upgraded but when I restart the machine during the unmounting of the devices the root filesystem got a Busy and didn't get unmounted. After the reebot I got some xfs error (log reply) and something strange happen (i don't know if it is related to the unclena unmount). The strange thing is that:
This is my fstab:
devpts /dev/pts devpts defaults 0 0
shm /dev/shm tmpfs nodev,nosuid 0 0
/dev/hda /media/cd auto ro,user,noauto,unhide 0 0
/dev/hdb /media/dvd auto ro,user,noauto,unhide 0 0

UUID=165e0dd6-87c9-4a0d-b228-df2aa65d94d9 swap swap 0 0
Please notice the mount options of the root partition /
And now this is the output of the mount command:
proc on /proc type proc (rw,relatime)
sys on /sys type sysfs (rw,relatime)
udev on /dev type tmpfs (rw,nosuid,relatime,size=10240k,mode=755)
/dev/disk/by-uuid/92f3d6f8-c66e-4fdd-812f-398d8de04cc6 on / type xfs (rw,noatime,attr2,nobarrier,noquota)
fusectl on /sys/fs/fuse/connections type fusectl (rw,relatime)
devpts on /dev/pts type devpts (rw)
shm on /dev/shm type tmpfs (rw,nosuid,nodev)
/dev/sda1 on /boot type xfs (rw,noatime,logbufs=8,logbsize=256k,nobarrier)
/dev/sda4 on /home type xfs (rw,noatime,logbufs=8,logbsize=256k,nobarrier)
/dev/sdb1 on /backup type xfs (rw,noatime,logbufs=8,logbsize=256k,nobarrier)
Like you will see the options are different but only for the root partition and we can find options not present at all in the fstab like attr2 and noquota.
I really don't know what is happening here, what I know is that it is not a kernel issue because I tryed with different kernel (custom compiled, arch, arch-lts).
May some people in the community has some ideas, I'm getting mad trying to resolve this!
Thank you very much!

Hey man, no one know anything? I posted in the wrong forum?

Strange CD/DVD drive issues

i never had a problem with my CD/DVD drive until around a month ago. I was using iDVD to burn a homemade movie for one of my friends and when it finished burning and I pressed eject. the only problem was that it didn't eject. It makes noises like it's trying but it doesn't actually spit it out. I have to restart my computer so it will recognize that it is still in the computer and then i have to pick up my MBP and shake it sideways to get the disc out. it's really annoying and i would really appreciate any tips that could help my situation. Thanks!

Make sure your software/firmware updates are complete and then try again.
I have heard of people blowing dust out of the drive and somewhat cleaning it get it working again. In your case sounds like the drive has gone bad. Hope you got AppleCare. They'll give a you new drive pronto.

Weird broken DVD drive issue

+(crossposted from here, this forum seems to get much more traffic.)+
Hi.
A couple of weeks ago, my Macbook's DVD drive stopped working. It won't load discs (physically) at all. This is not a software issue, it won't load under Windows or external boots either.
I figure the drive is dead, and I'm not that broken up about it… I almost never use it.
However, there are two interesting side points, which aren't very common judging by the lack of Google results:
• Ever since I got my Macbook, the drive made a sort of 'spinning' sound every time the empty drive was powered up, i.e. on waking from sleep or starting/rebooting, the drive would make a quick 'back and forth' noise, which none of my friends' Macbooks made. This only happened when the drive was empty; it was silent when a disc was loaded. My drive is a *HL-DT-ST DVDRW GSA-S10N* according to System Profiler. I never did check whether my friends' drives were identical, although one friend did have the exact same model of Macbook. For all I know, this is entirely common with my drive.
• When the drive died (exactly when it died), another thing started happening as well: When I lift the Macbook's screen to wake it, I cannot type my password without extra characters (which are, of course, obscured) being added… I always need a second attempt to unlock my computer. I can't help but think that these two issues are connected… they started simultaneously.
So… is there any chance my drive is not dead? Does the fact that it always made strange noises have anything to do with it? And how does the phantom typing figure in? Is there a way to see what characters the system if dumping into my password box?
Thanks for any help. Again, I'm not worried about it, more curious. I'm also well out of warranty.

I can't speak to the specifics of your situation, hudgie, but I can tell you that the SuperDrive on my first MacBook conked out and had to be replaced. Fortunately, it was still under AppleCare. The symptom my MacBook presented was that it would not mount CDs. It would accept them and then spit them right back out. Curiously, it played DVDs just fine. This was a progressive failure. At first, I could rotate the CD and have it accepted. Then I would have to fiddle with it longer in order to get it to accept the CD. And, finally, it would not accept a CD at all. I did try a cleaning disc on the drive, without success. If you haven't tried a cleaning disc, I would suggest trying that, especially since you are out of warranty anyway.
Good luck!

MacBook Pro DVD drive issues

Hi there, recently I got a something strange problem with the DVD drive in my MacBook Pro 15" (2,2Ghz Intel core Duo, 10.5.8). Beginning with the error 0x80020042 first I tried cleaning the laser lens which worked for a few times, I also had errors like "... illegal access..", or the drive just could not read from disks, or the system does not recognize a blank disk was inserted. Using Toast to burn files to CDs it turns red indicating that there is not enough space on the disk even if the files are small, only a few kilobytes or megabytes large. Using the Mac OS I get the same message.
I'd appreciate your help and suggestions.
Thanks.

maybe its hardware issue if you contact apple store or apple support they could help you
