IMac disk drive will run DVD but not audio cd

My IMac disk drive will not recognize a cd, it will,however, run a DVD just fine.  Help!

Most any external reader/writer will do - I've used one for years. And they are generally less expensive than the Superdrives + labor.

  • Satellite A210-12U - DVD RW Drive will recognise DVDs but not CDs

    I've got a 4yr-old Toshiba Satellite laptop (Model: A210-12U) which I recently restored using the recovery CD - it's running Vista SP2.
    Please bear with me as this may be a long-ish story, but it helps to explain my problem.
    Around a year ago, a virus made its way onto my laptop and almost destroyed the OS - I'd consider myself to be fairly knowledgeable software-wise having studied IT at college, and so set about the long process of trying to fix my laptop without resorting to the recovery CD.
    It was a patch job, but after a month or so I had it working again and it was fine for a further few months or so, before I noticed that my DVD RW Drive would no longer read and/or burn CDs. I spent hours trawling internet forums for help without any luck and was subsequently convinced that it was a hardware problem.
    As I needed to use a CD burner, my cousin lent me his USB DVD RW drive and this didn't work, meaning that logic suggested it wasn't a physical problem with the drive, rather that it was more likely a problem with the registry/OS. This wasn't surprising seeing as I'd done a basic patch job following the virus infection a few months earlier.
    After becoming increasingly frustrated with my laptop in general, I backed up my data onto a portable HD and used the recovery CD which came with my laptop. The laptop booted the CD up when it was outside of the OS (as per the instructions that came with it) and restored the entire computer to its original state (and solving a lot of the problems that were caused by the virus in the process).
    I've spent the last week re-installing programs, copying back data etc. and was in the process of installing some software from a CD today, when I noticed that the laptop was having difficulties accessing the drive. Windows Explorer knows the drive is there; it is listed in "My Computer" and will also have the little CD icon alongside the pointer when it is trying to load the CD up - suggesting it knows there is a CD in there.
    However, the drive itself will still read DVDs which suggests it could be a physical problem with the drive itself (I read somewhere about the laser having to change its angle accordingly when reading CDs and DVDs). I question this however, as the computer was able to read the recovery CD when I was in the process of a complete restore (and it was having the same difficulties reading CDs in Windows before the restore).
    I've tried all the methods suggested in similar posts on this forum - Microsoft Fix It, Uninstalling the drivers etc. to no avail... So yes, I am pretty much stumped and am wondering if anyone can help?
    The DVD RW Drive is listed in the Device Manager as HL-DT-ST DVDRAM GSA-T20N ATA Device.
    Thanks,
    Ben

    Hi Ben
    In my opinion it is hardware related issue. You are right about lens position. It must be calibrated for CDs and also for DVD. If the optical disc drive cannot read one of these medias in general it can be lens calibration problem.
    To be honest ODDs for this old A210 are not expensive anymore. I recommend you to buy new one or used one on eBay. Exchange it and test the functionality.
    To be honest I dont believe there is some trick that can help you to get it working again.

  • IMac will play DVDs but not CDs

    My 2009 iMac will play DVDs but not CDs (bought music CDs and burnt CDs). The last time I tried (successfully) was December 2013. Can anyone help?

    Start a new topic and don't hijack this one.  You're problem is different from the OPs. When you start the new topic give your system version, iMac year and model and what type of CDs you can't read, i.e. commercial or those you created yourself.  Also if you can read DVDs.

  • Will read DVDs but not CDs

    I have a satellite a305-s6872 that will read dvds but not cds.  It was reading cds the last time I tried (October) but now it's not.  This means that I can't play or burn cds.  It also means that I can't install any programs that come on a cd.  Please help!

    I have the same problem. It reads DVDs, and rejects CDs, even perfect/new CDs.
    Apple Support told me there will soon be a software update (in a week?) to fix this problem, but I am not convinced.

  • Combo drive can mount DVDs but not CDs

    Hi Everyone,
    Can you help?
    Just recently my combo drive which is a MATSHITA CD-RW CW-8122:
    Firmware Revision: BA21
    stopped mounting CDs. It won't take any type of CD, but will mount and play DVDs just fine. I've tried resetting the PRAM, running Disk Utility, archive and reinstall, all to no avail. Any suggestions are highly appreciated. Thanks! Emi

    Welcome to the Apple discussions.
    When you click on system preferences (light switch with the apple on it) and then click CDs & DVDs, what does it say for when you insert a blank/music/picture CD?

  • Superdrive will open DVD but not CD

    My Superdrive will open and read a DVD with no problem but refuses to load music or software CD`s . This has recently developed - it used to be fine.
    It is the Sony DVD RW DW-U10A.
    I have tried the air duster but to no avail.
    iMac is coming up to four years old - surely not time for the scrap heap yet ?
    Thanks,

    RE: Battery Replacement Suggestion
    Hi.
    I also have intermittent superdrive problems on my iMac and this clock battery suggestion is about the only thing I haven't tried yet.
    My issues are with DVD playback mostly, but burning CD's has a mind of its own - sometimes it burns, sometimes it doesn't.
    DVD Player is 4.0, but other players i.e. VLC encounter the same playback problems.
    iMac is 17-inch flat 1.25 GHz
    Panther 10.3.9 (will not be updating this machine to Tiger)
    Superdrive: SONY DVD RW DW-U10A, Revision A43h
    Could you direct me to specific documentation or step-by-step instructions on the clock issue?
    Thanks!

  • DR8-A will read DVDs but not CDs

    After a few months of use my MSI DR8-A has just stopped reading cds in both windows and dos. I hadn't installed or removed anything and I have flashed the drive to the most recent version. I'm assuming the cd laser is either dirty or knackered, but if anyone has any ideas...

    Replacment drive has the same issues, I did upgrade the Firmware to 1.5 and it seems better.  I will give it some time to test, first reaction is not favorable...

  • Imac G5 Play Dvd but Not Cd

    I have a Imac G5 with a superdrive and if will play DVD but not CD. Anyway i can fix this?

    Two ways that might fix it (the superdrive uses different lasers for CDs and DVDs):
    1. Clean the superdrive with a proprietary lens cleaner that uses tiny brushes.
    2. Reset the SMU:

    my disk drive will start up when i plug it in, and runs for about 30 seconds, but wont get recognized in my computer. It used to show up in the finder but that doesnt happen anymore

    If you go to Disk Utility, can you see the drive on the left hand side? If not, then the drive is dead. You'll have to buy a new drive.
    Also, this forum is "Older Hardware". We specialise in hardware from the 1980s.

  • Disk drive will not click or accept disks ?

    Disk drive will not click or accept cd's or DVD's

    What I did was I kept putting it in until it accepted it. I don't know if yours will do this. With any disc, my iMac and my mom's MBP accepted discs after about 20 tries.

  • DVD Drive issues, plays CDs but not DVD data or regular - Satellite (unknown series type)

    I tried to update the firmware but ran into some strange issues. First of all according to google, the drive is manufactured by Panasonic. Toshiba doesn't make their own drives? For this reason I wonder if it is improperly detecting the drive make/model.
    Anyways I downloaded the firmware update for it, version 1.03. It is a MAT**bleep**A UJDA760 (going from memory, model may be slightly diff like UDJA). When I run the firmware update it doesn't detect the drive at all and says it is for a THINKPAD?? Weird...
    Also, if you have a link to a guide for removing this drive I would appreciate it. I want to verify that windows is detecting the model/maker correctly. It is not one of the simple hotswap types, it looks like I have to remove at least the entire bottom of the laptop.
    I am working on this for a client, I do tech repair on craigslist but my laptop hardware expertise is limited most of my experience is with desktops.

    Typically if the optical drive can read CDs but not DVDs (or vice versa), there has been a hardware failure of the DVD or CD circuitry.  Drivers/firmware aren't going to solve the problem, only replacement of the drive.

  • HP Pavilion DV7 2206TX - DVD drive reads DVDs but not CD's

    My HP Pavilion DV7 2206TX - DVD drive reads DVDs but not CD's.
    When I insert a CD, the drive tries very hard to read the CD but gives up after about a minute.
    I get no error message.  I do not see the Auto play message.
    Windows Explorer does not recognize the DVD drive.
    When I insert a DVD, I get the Autoplay menu, Windows Explorer recognize the drive and the DVD. I can play the DVD using any number of Video players.
    I would welcome advice relating this problem.

    your HP Pavilion needs a new DVD driver. I ran into many problems such as this when troubleshooting computers in school.
    A DVD drive should play CD at any time:  While a CD driver will not play a DVD disc. Do not think there is a problem with sofware because it will only throw your troubleshooting skills  out the window and it will confuse you.

  • I have a 2010 Macbook Pro and am a very new user to Mac community. My Mac is just hanging and I am unable to shut it down or do anything at all.  I left it for 2.5 days hoping the battery will run flat but it is not working. Pls help! I am desperate. Tx

    I have a 2010 Macbook Pro and am a very new user to Mac community only started to use this PC a few weeks ago.
    My Mac is just hanging and I am unable to shut it down or do anything at all.  I left it for 2.5 days hoping the battery will run flat but it is not working. Pls help! I am desperate. Tx

    In order to resolve the issue if it occurs again, more info would be helpful as to what occurred prior to the "hang." One potential fix would be to try a Safe Boot:
    After the Mac is completely shut down, push the power button and immediately after the startup tone, hold down the Shift key. The Shift key should be held as soon as possible after the startup tone but not before.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    There should be a message that says "SafeBoot." After the Mac is completely booted, try restarting and see if the issue is gone.
