DVD not Recognised

I have an iMac and it doesn't recognise a DVD, it just ejects it. CD works ok, and if I sign in as a guest the DVD works ok. I have tried all the settings I can find but nothing works. can anybody help

If it's just one DVD then it's probably damaged. Have you attempted to use other DVDs, if you have and still have an issue then go to your local Office Supply store and get a CD/DVD cleaning kit. It's possible that is all that is needed, a good cleaning.

Start up DVD not recognised by mountain lion

My start up DVD not recognised by mountain lion-how do I get around this for restoring from time machine?

It's not very clear: Are you trying to reinstall Mountain Lion from a DVD copy you made of it, for some reason? And if so, why would that help you restore from Time Machine? Please give more information. Properly, to either reinstall Mountain Lion, or to Restore it from Time Machine, you need to reboot while holding down the Command - R keys as mcsound above recommended, to boot into the Mountain Lion Recovery Partition to do either.

DVDs not recognised since updating to 10.6.8

Since updating to 10.6.8 I get the message format not recognised when inserting DVDs movies / recordable media etc. Any ideas.

Just to clarify: DVD movie discs inserted into my iMac come up with the message "the disk you inserted was not readable by this computer." Data, software install disks and audio CD's work fine. I have tried repairing the disk and permissions, as well as creating a new user account. I applied the 10.6.8 update to my wife's macbook and no problem reading DVD movie disks. So is this problem specific to the iMac? I have a 2.66 core duo with 4GB of RAM. Any ideas anyone?

Help. HD DVD not recognised by Toshiba player

I am burning a 40 second slideshow with no sound onto a looping HD DVD for display on a widescreen. I have burnt around 9 DVDs so far with a variety of settings, but the Toshiba HD-E1KY player I have to use recognises none of them. It simply brings up a box saying this is not a DVD.
Looking through the forum it seems Toshiba players may be an issue, but has anyone any advice on some simple settings that work with DVD SP 4.2.1
ANY suggestions welcome as I dont have enough hair left to keep ripping it out at this pace.

How did you create the HD DVD and how did you burn it?
Apple implemented some of the HD DVD specifications but not all of them and it seemed to be more of an issue that Toshiba had to update Firmware on some machines to make it closer to HD DVD. Does the message box say not HD DVD or not a DVD? What files/folders are in you build file?

Data DVD not recognised

I burnt my images on my old PC on a DVD, marking it as a data DVD and making it presumably compatible with other systems. It can be read by other PC's, but not by my new MacBook. It marks it as an unburnt CD!!
It reads CDs & DVDs just fine.
Please, if you have any ideas...
MacBook Pro 15" @2.1GHz Mac OS X (10.4.7)

Sonic is the name of the company (they bought Roxio), not the application. But anyway, I have Sonic DigitalMedia Plus on my Dell and I see an option to burn as Data > "Direct to disc" which would indicate it is probably using packet writing (similar to writing to a floppy or DVD-RAM), then they have the option to click "Make compatible" in order to share the disc. Maybe you didn't click that? If your other PC's also have the same burning software, they would be able to read it even without making it "compatible". Or make sure you are clicking on "Data Disc" instead when creating new discs.
Let me know how you made out.

[SOLVED] Commercial DVD Not Recognised

I have recently bought a commercial DVD that will not play on my PC. When I load it into the drive, it is just not "seen". Kaffeine reports a dvd read error, while smplayer, etc think there is no disc in the drive. All my other DVDs (with various region codes) play perfectly. This particular disc works fine on the set-top player on my TV.
I have checked that libdvdcss, etc are installed OK.
Does anyone have any ideas what's causing this, and suggest any fixes?

Yay for going legit huh? On a more serious note, do you have any possibility to test the dvd in other drives besides yours? It might just be that your drive is getting old or the dvd quality could be better and your drive has some difficulty reading it. Even pressed media can be of bad quality and some drives work miracles while others seem to quit at the first sign of trouble and I guess it also depends on the type of defect.
As for the possibility of the problem being caused by a copy protection, could also be the case, although I can't say much about that as I haven't looked at that for a long time, you could look here [1] as it may have something interesting. On the other hand, I'd say many standalone players use the same drives as available for computers so I'm not sure if someone would risk breaking things in that case.

Satellite A60 CD/DVD not recognised - URGENT

Hi ive just bought my A60 laptop and ive noticed that the CD/DVD drive is not reconised...neither from the BIOS! I ve installed the latest bios updates but still nothing...pls can you help me?

Hello
Like Maier said in this case it can be hardware malfunction. If the device is not shown in BIOS it is probably some serious. Please contact the service partner in your country. You can find them on http://www.csd.toshiba.com/cgi-bin/tais/su/su_gaspLocator.jsp?pf=true .

Burnt DVD not recognised on Windows Computer

My wife and I have recently started our own business, and are using 'Disk Utility' to do daily backups of our work onto DVD+RW disks. Every few days we erase the old disks and re-write over them. We have 2 computers an IMac G5 on Tiger and a Laptop on Windows Vista. Due to the nature of the work I often have to use files created on the Mac on the Laptop. I would like to use the previous days back-up disk to transfer the files to the laptop as it is the most hassle free method of transferring the files over, especially when working away from home. This is where the problem starts, the burnt disks are easily read on the iMac, I have checked them several times as I'm paranoid about loosing my work. But when I put the DVD into the Laptop, a pop-up asks me what I want to do with my blank disk. I checked the help files on 'Disk Utility' and they talk about setting the volume format to a microsoft setting but when I erase the DVD that menu is greyed out. What can I do as the only way for me to transfer files at the moment is by using my iPod which takes several transfers to copy everything over, using up a lot of my time.
Regards & Thanks for any responses
John Curwood

Data disks created with Disk Utility are normally Mac format. To read them with Windows you need MacDrive

If you use the Finder to burn the DVD, it will be in both Mac and PC format, and should work with no additional software.

Tecra M5: UJ-841s not recognised as DVD/RW by any burning software

I have seen on other posts that it is common for the drive to be identified in the Device Manager as a DVD-RAM (which is what is happening) but my DVD Multi-recorder (on a Tecra M5) is not recognised by any DVD burning software.
Is there an update or driver I should have?
Thanks

Hi
My first question: Do you use the Toshiba OS from the Toshiba recovery CD?
Did you install and use several burning applications together?
In my practical knowledge its not advisable to use different burning programs together.
You should use only one. I recommend Nero. Its nice.
If the sonic is installed on the HDD, try to remove it and use only the nero.
If the drive will be not able to handle the DVD medias, you should check different brands.

Erratic behaviour by internal DVD-writer (not recognising discs)

Hi,
Earlier today I went to burn a 2 small Word files to a blank CD-RW, and ever since my iMac's internal DVD/CD-writer has been playing up.
When it went to burn the disc, it got stuck in the preparing phase (with the moving diagonal slashes progress bar), after a long while of this I tried to cancel the burn. Unfortunately the system wouldn't respond to the cancel button being clicked so I had to Force Quit the Finder.
Following this I was then unable to get the system to eject the disc so that I could try again. Eventually resetting the computer seemed to solve this. But ever since then the computer has been behaving erratically, including;
- not recognising (and so ejecting) previously recognised burnt CD-RWs,
- not recognising the original blank CD-RW,
- not recognising other blank CD-RWs,
- rejecting multiple blank CD-RWs in a row as faulty discs,
- getting stuck in the burning process preparations.. again! (when it did for once actually recognise a blank disc),
- and not recognising multiple movie DVDs.
I did in the end get it recognise some movie DVDs again in the end, but aside from that it's still misbehaving.
I've reset the machine multiple time, both due to problem, and simply to try to see if that'll fix it. I've also zapped the PRAM, checked the System Profiler to ensure the drive is fully recognised by the machine/OS, I've also tried leaving the machine to cool for 10 minutes, and checked the CD and DVD preferences panel. I don't have a Drive cleaner disc yet, but then the shops are closed now so I wouldn't be able to get one till tomorrow.
Until today it's worked hitch free (aside from rejecting a few particular 'Movie DVDs' (of the correct region) for no apparent reason). I've previously been able to burn all sorts of files on to DVD-Rs, DVD-RWs, CD-Rs and CD-RWs, without a problem. And it's hapily read all sort of different discs with different media on them.
Thanks
Jessika

I would just get it repaired.

Superdrive not recognising DVD

It seems I'm in a similar boat as several others in this forum. Have an eMac OSX10.3.9 with superdrive and have been burning and playing movies with no problems. In the last couple of months it will not recognise ANY DVD at all - including DVDs I have created myself and commercial movies that I have been able to previously read.
I have no probs reading CDs.
In every case after inserting a DVD it comes up with a message "You have inserted a disk containing no volumes that Mac OSX can read."
I have gone through the forum and taken up suggestions including:
updating firmware: software indicated no update required;
resetting NVRAM;
using CD lens cleaner
using Path Burn – software indicated no patch required
I've noticed there's been several postings over the last couple of months regarding this or similar probs with DVD. Is it anything to do with recent upgrades? Hope this inspires further troubleshooting - I'm pulling my hair out! Or have I missed the posting with the magical solution?
eMac Mac OS X (10.3.9) 800MHz, 78mb SDRAM, Superdrive

Hi Paula
Apparently different wavelengths are used to read DVDs and CDs. I found a lot of stuff out by reading other postings on this site, plus some extra bits from the response to this posting.
Meantime, I upgraded to 10.4.8 to no avail. Then a friend recommended booting in Safe Mode and lo and behold, the offending DVDs were read. Unfortunately, because this mode uses limited extensions, it wouldn't actually play those that were movies, but at least I could get some data from some. The DVDs also played when I booted in OS9.
They also recommended creating a new user in OSX, which I did but had the same problem. Which tends to make me believe there is some offending extension, rather than a cleaning issue - a bit of a nightmare to sort out!
May just opt for a new drive - reluctantly.
Cheers
Mrs Dynamic

DVD Device not recognised as a DVD Device

Hi,
I am having a very annoying problem.
Since installing arch (quite a while ago) I have not been able to use my DVD device for DVDs. It is recognised as a CD-ROM only, whereas it is really a DVD reader / CD burner (not dvd burner). I have been able to use this for reading dvds on windows, then when i used to be on ubuntu. Arch doesn't see it properly.
When Arch loads, i notice Universal CD Device Driver or something, version 3.20, is loaded for hdc (my device). I think it is not recognised properly.
I have tried manually mounting different devices, checked dmesg for any changes between reading a dvd and reading a cd (no new lines in dmesg when a dvd has been inserted). It is really, really strange and I do not know what to do.
Can someone please help me? I can download the drivers for my device (windows tho) if that helps.
Any response is greatly appreciated. Thanks

yes I have that, no difference. I think it is a problem with the firmware that is flashed onto the device itself, or something like that. is there a way to flash firmwares in linux? all the toshiba firmware installation things, or the rpc1.org stuff are all for windows. how can i do it?
or, if there is a way, i'd like to reset to the original firmware, is there any possibility of that?

Original DVD drive not recognised

My macmini (1.83Ghz) suddenly stopped recognising its own DVD drive. No mods done to the mac mini but suddenly it does not recognise the drive. there is a movie DVD in it, which spins from time to time (for example when rebooting the mac mini or waking from sleep) but system profiler does not see a DVD drive (when i click on disc burning it shows 'No disc burning device was found. If the device is external, make sure it’s connected and turned on.' this is annoying since i cannot remove the dvd that is there nor play it.
did anyone ever come across this? what can be done to fix it? how to eject the disc manually to see if it's the disc which is the issue?

i did that. the mini took a long time to start but still not dvd drive on the system profiler. i don't know if related but on starting up, it also behaves funnily. after the grey apple screen with a spinning wheel below, i get a blue screen and it seems that nothing happens for ever. the only way to get back into the mini is to set it to sleep (pushing the power button does that) then waking it up. i then get a started up mini but it does not respond to mouse action (although the arrow moves, the click don't seem to have an effect and the keyboard is unresponsive (both are bluetooth). after a while though (around 2 min) they both operate correctly which is how i reply to you. this has been the case ever since the dvd drive disapeared so the two problems appear linked. the mini is running snow leoppard.
please help me - thanks.

I am trying to install a brand new WD 500 gb sata internal hd in my macbook pro. the original install dvd does not recognise the hd. all hardware is ok. any help?

For some reason OS X disks (whatever edition or flavors) that are supplied with Apple products only seem to contain a limited knowledge of available hard drives on the market at the time of thier publishing. This (rather opportunistically) creates a "Best Before" stale-OS X-software-copy situation where upgrading to or replacing a defective internal SATA hard drive with a newer, better or larger one is a largely hit and miss affair.
If you buy the latest and greatest disk drive available for any older Mac you are likely to run into unresolvable problems making a clean re-install of your own, old edition or flavor of OS X onto any newer or larger hard drive since the OEM (gray) "OS X Install Disks" that Apple supply with retail products seem to contain only time-sensitive lists/mapings of then-known target drives that the Drive Management Tool in the then-published old "Installer Software" will support.
Presumably new (colorful "X") retail versions of OS X (10.whatever.whatever) also contain time-limited Installers with limited knowledge of and adaptability to/compatability with a limited number of old hard drives then kicking-around on the market.
This is especially a problem nowadays since the countless "puny old" hard drives that have been on the market are largely obsolete in a few months time, as manufacturers continue to produce larger and cheaper units, discontinuing older puny products... So if your drive fails you need an exact old (or similar familial) replacement drive for your "backup copy of OS X" to do a fresh, clean OS X re-install. Otherwise you need to purchase a new retail version of OS X, since yours is now effectively obsolete. Purchasing an old, puny drive to re-install your version.flavor of OS X to avoid buying a new version of OS X is a rather false economy.
If you still have a working old hard drive with your old polluted 10.version.flavor of OS X still working on it you apparently must clone it with Time Machine or the newest version of Disk Utility (disk image copying) to most newer, larger drives, and a clean reinstall to such new hard drives is not possible.
