Dvd's won't mount

I can only join the rest of you with trouble.

I burn and verify on top brand discs and before I eject the disc the very first time, I try it out. It works fine and I eject the disc, but if I put in back in it won't show up. I hear it spinning, but no errors or any feedback is shown. It just pops out again.
But the disc will play on my newer iMac and on my regular DVD player

I have no problem playing CD's and commercial bought DVD's, just the ones I burn myself.

While I'm annoyed about this, I'm happy to see I'm not alone. It seems it's a problem that's out of my reach (right now)

Im just adding my voice to this post saying I too have dvds that wont mount.

My DP1.8 G5 10.4.3 just spits them back out?!

Previously I had burning issues with Toast 6 so I bought Toast 7 and still had the media error codes people keep referring to. I bought a lens cleaner and it seemed to work at the time however the problem still arises occassionally as well as spitting commercial and data dvds.

I have a feeling it is a software/firmware problem in OSX.

I had trouble with the DVR-106PB that shipped with my G5 not reading DVD-Rs (other media was ok though), so I replaced the drive with a DVR-110D (plenty of people report this drive is fine for the G5), and now it won't read anything commercial CDs, DVD-Rs, CD-RWs, what have you -- yet it is recognized by the system, responds to tray eject commands, etc.

I'm also, like you, running 10.4.3 on a DP1.8 G5.

APPLE! I summon thee! Answer this thread or include a fix in 10.4.4 (to be released to coincide with MWSF tomorrow?? maybe?)

Some of you may find this as unbelievable as me. I finally called apple about the problem I have been having: DVD+R's burn, then mount, but after I take them out the machine won't read them (well, it will if you just leave the disks in the drive for hours). Well, what they told me was that my burner is not supposed to play DVD+R's! You can see in my sig when I got this machine, so I would imagine that machines made prior to this will also have the same problem! It CAN burn +R's, but NOT read. Not sure what the logic is there.

The rep could not explain why my machine could, in the beginning, mount DVD+R's without a problem or why it is still able to mount them just after they've been burned.

I've noticed that some of you have mentioned in your specs that your machine is a DVD-R, meaning, according to apple, it isn't supposed to read them. It doesn't matter if your profiler tells you " DVD-Write: -R, -RW, +R, +RW" as mine does, if it's a DVD-R/CD-RW, then...

Hope this helps some of you.

No, there's no way that what you were told is true. I can mount DVD+R/RW's, just I have some problem mounting the ones I burnt. I put them in the drive, and it's like it doesn't detect anything in there. Sometimes they do start to spin, and then they mount. DVD+R is becoming the most popular type of writable DVD's (if they're not already). Since the burner burns DVD+R/-R, the drive can certainly read them too.

I really hope that what I was told was not true because it doesn't make any sense. Why have the function to burn +R media if you can't read it? I asked the rep this question, but did not get an actual answer. I also asked why my drive reads +R media sometimes or after some effort (I leave the disk in the tray so it opens and closes itself until the drive decides it will read it), and also why it was reading +R when I first got the machine, but his answer was probably what anyone will come up against: "reading +R's is not in the product description so it's not apple's problem."

If anyone can shed additional light on this, I'm sure many people would appreciate it. I, like it seems many others, bought +R's knowing that the drive could write them, backed up ~GB's of info, and now can't access the disk on the computer on which it was written!

Oddly, I CAN mount the disks on an old imac G4 that was produced a year before my computer. Go figure!

I read a lot of post about this problem and nothing
seems to be resolving.
My superdrive (a pioneer 106d) refuse to mount the
dvd-r it just burnt but I can read them on my old
titanium. On the g5 the superdrive works well with
dvd-rw, cd-r, and with older backup I made on dvd-r
(2-3 months ago). And I use different brand of dvd.
If someone of Apple can wake-up and tell us (a lot of
people on the net) what's happen and, maybe, if there
is a solution, it will be great.

I think I have figured out what's going on. For some reason, if your dvd drive reads a regular consumer purchased dvd movie, say like Big Fish, as the first disc it reads on startup, it won't read a dvd-r you made. If you do the reverse, if you have the dvd drive read a dvd-r you made upon startup, it won't read the consumer dvd. I have no idea why this is, but I've been able to reproduce this in not only my powermac, but my powerbook.

Pls forgive If I am being redundant. I see many post
on this but no solution beyond one person Robert
saying that is "fixed itself".

I too am having the problem of DVD won't mount on a
dual 2Ghz G5. Superdrive just won't recognize a DVD.
Any DVD! Purchased commercial DVDs that work on all
other players in the house, NetFlix, and HP dvd+r 8x
blanks...

Music CDs are fine and CDs burnt by the superdrive
are fine.

Just not DVDs

Is there a solution to this out there?

UPDATE
My problem was resolved with two steps.
1) returned unit to Apple and they replaced the superdrive.
- that solved the cannot read any DVD

2) purchased ilife to get a more "universal" DVD burner in iDVD
- that solved cannot write to DVD (apparently DVD +R is not the same as DVD - R)

Hi. The problem seems to be slightly different with everyone that posts. I have a sony drive for DVD-Rs only (it says it in the manual). I've been having this problem for the longest time. When I burn a DVD, my computer won't (99% or the time) recognized it when I reinsert it into the drive. I thought it was a hardware problem, so I did a hardware test but that turned up nothing. I thought it was a iDVD problem, so I recently started using DVD Studio Pro, but still, it won't recognize it's own burnt DVDs. I reloaded the OS, thinking it was software related, but still nothing. It doesn't mount but it does say that I've inserted a blank disk. The DVDs that I burn work fine on other players and on other Macs, and my mac reads commercial stuff, no problem. I called tech support when I had complimentary, but they've got nothin'!

I hope I'm not annoying anyone with my little variation of this problem, but the problem is just so annoying that I have to try and get to the bottom of this.

Thanks

PS, I should clarify that I am burning films, not data. I haven't tried data yet.

ReDnArtSO,

Sorry, I would prefer a backchannel on this, so anyway: Are the disks you are using DVD-R or DVD+R? I'm assuming -R since you tell us that your drive is only for -R, but.... Judging by your model - later than mine - your computer must be able to write DVD+R.
Hope this isn't a silly question, but your problem just sounds too suspiciously like mine.

Also, if it is not a media problem, then I would simply suggest getting a new drive. They are reasonably cheap nowadays - and you can get one with DL capabilities... I believe there are some useful threads on here on replacement drives.

Obasan,

The disks I use are -R. There is a whole little section in my manual that says the drive will only work with -Rs. I looked under "tell me more about this mac" and it says that the drive type is a sony, something, something, -R.

I still have a few months to go on my warranty, so maybe I'll bring it in and ask for a new drive with DL.

Thanks.

P.S. I had updated from OS 10.3.7 to 10.3.9 a few months ago, and got so fed up last night that I tried an "archive and restore with my OS 10.3.7 disk that came with my computer. Still...it didn't recognize the DVD! So, I guess I've done what I can from both a hardware and software angle. New drive sounds like the way to go.

Here, we have the same problem on 3 G5 buy on the same time. We can change the DVD burner (the price isn't higher) this is a rapid solution but I would like to know if this problem will be correct bu Apple.

This problem appears now on 10.4.3, we not have this problem on 10.3. I think it's a problem with the using time, not a software problem

Well I am having a similar problem with the Pioneer DVD-RW DVR-106D that came with my machine. Can successfully write to DVD-Rs (video or data discs) with Toast 6 but they will not mount upon reinsertion. This is a major problem! I cannot access important archived files. They mount just fine on other machines.
A hardware test seemed to confirm there were no problems there.

What's up with this Apple? It seems many of us are having this problem. Do I smell another class action law suit here?

I just encocuntered this problem after making a DVD in iDVD. The DVD mounted and played and everything seemed peachy. That was last night.

This morning I put the DVD into my recently upgraded Pio 110D and....nothing. It wouldn't show up on the desktop. It was, however, showing up in Disc Utility!! I popped the disc out and rebooted. Now it seems to like the disc again, at least for the time being.

This can't be a drive issue, can it? I mean, considering how many other people have seen this problem using different drives? Strangeness.....

i have been reading about this, my problem is i cant read dvds i have burned my self, i read that it might be that my drive requiers cleaning, but it reads store bought dvds without a problem, ive had my computer for a year and a half and never experienced this problem

i have another dvd drive problem, my copy of The Rock movie was scratched, when i tried to view it the drive would lock up and my computer wouldnt recongnize it, i had to press the special eject button, and i thought that it happened because the dvd movie was all scratched up, but yesterday it happened with a brand new movie

this is begining to stress me out alot, i dont know what to do, i have alot of backed up data on dvds, and ive tried reading dif brands of dvds and same thing happens, it ejects it:( mac are supposed to be perfect:(

im thinking of formating my computer but i have all my back up on those dvds! and i dont want to format it and not be able to get alot of data i need of those dvd's what can i do or what should i do:S?!

i have a pioneer dvd-rw dvr-106d
