El Capitan grateful suddenly don't no optical drive

I have a MacBook Air running El Capitan, purchased 3/2016. I bought the optical drive when I bought the computer. I used the external drive to burn DVDs and CDs. Everything worked fine until I plugged the optical drive yesterday. I opened iTunes, plugged the disc inserted a cd and the window showing that I inserted the cd never popped up. The finder does not display the drive, even though I checked in preferences to show him. The only way I could safely remove the cd was going to disk utility where I could see the disc and the cd and eject it.

I checked to make sure that the drive still works by inserting a DVD or CD in the optical drive. The two will play correctly, but I still have to go back into the disk utility to eject because the drive does not appear anywhere else.

With iTunes running and the drive plugged with a blank CD inserted, the "playlist to burn to the disc" is grayed out, because the computer is not recognizing the drive.

What can I do to get the computer/El Capitan to recognize the drive again?

Reporting system shows the optical drive? Try the commands from the Terminal after the connection of an optical drive...

    Hi people

    I hear and read that El Capitan stop construction in the optical drive to work? I don't know if it's true, and other bugs. I remember when I upgraded to Yosemite this happened to my mac mini, and the super drive was not recognized. However, it was fixed. Although I used to be able to run when any player with the mavericks, but Yosemite has changed all that.

    In any case I had to go to Yosemite, and I'm not sure whether for now, if it's going to ruin my drive and other things. I have a 2012 end pro MacBook. Everyone has problems, or advice to share, or stick to Yosemite.

  • Equium L350 - optical drive problem

    I have a beautiful Equium L350 which I use for very basic tasks such as e-mail and internet shopping.
    I'm an absolute fool when it's nothing technical, even remotely.

    However, I bought this laptop in May last of PC World, Cardiff and were very happy until a few weeks ago when I went to use the 'optical driver' (thing stick you a disc in?) for the first time.
    My daughter had a Barbie MP3 player for her birthday and I was trying to download all the relevant stuff from the disk, and nothing happened.
    I don't know from reading this that you can see how hopeless, I am!

    I have assumed that I was doing something wrong, until a colleague told me that he had the same problem with their Toshiba last year and there was a problem with the optical driver.
    In any case, for 3 weeks, I have been ringing Toshiba trying to get some help.
    I'm losing the will to live!

    I'm put on hold each one each time for more than 20 minutes at a time.
    I haven't talked to anyone! I sent (no reply!) and PC World have been just as useless as telling me that I need to contact Toshiba direct.

    Did anyone have a number for them to the United Kingdom for service / warranty repairs / help of any kind! I love the machine, but the lack of customer service is soul destroying! I would be so grateful for any kind of comments!

    Thank you ever much for taking the trouble to read this :)

    Sarah

    Hi Sarah

    May I ask what's exactly wrong with your laptop?

    You said something about Barbie Mp3 player.
    How to connect to the laptop and what do you do with this 3rd party device?

    You want to put some mp3 files to this player?

    Sorry, but I don t understand you the problem and I can't see any link between a drive optical (I think that you are which means that the CD/DVD drive) and Barbie mp3 player

    By the way:
    If there is something wrong with the hardware you need to always contact the ASP in your country.
    Here you will find the ASP database:

  • Satellite A20-130: SD-R2412 cannot read that DVD burned in some optical drives

    Hello

    I have a laptop Satellite A20-130, running Windows XP and Ununtu Dapper in a double score. My 2nd laptop is not a Toshiba. When I burned the DVD (DVD + R) with my laptop Toshiba no and played against them in my Satellite everything has worked well.

    However, when I bought a new optical drive for my 2nd my Toshiba laptop suddenly stopped playing DVDs burned in this new optical disc (I was using exactly the same brand of disc and the same format - DVD + R). I tried the old DVD (those burned in the laptop before that material from the optical drive has been upgraded) and they can still read perfectly well.

    This problem applies to both Ubuntu and Windows XP. Computer support portable 2nd said that sounds like a problem of firmware with my Toshiba. I updated the driver for my optical drive Toshiba R2412 SD (which according to the manual of the leader, seems to fix a DVD-Ram compatibility issue). Now the reader occasionally reads some of the new DVDs burnt (after doing lots of noise and waiting for ages), but more often that not, I get an error message saying that the device cannot be read, because the format is wrong or the device needs to be formatted.

    This computer non-Toshiba laptop read DVD, it burns using the optical drive improved perfectly.

    Hello

    Satellite A20 is old enough laptop model, and after intensive use, it may be that the disc is more sensitive. If all this happens occasionally there no explanation just why this happens.

    I know it's pretty boring, but I don't see any magic solution. In the end, you should test with new disc.

  • Empty optical drive is ejected at random (all 2-15 min)

    I'm having a problem with my laptop recently bought Studio 1535...

    Data sheet:

    Vista Home Premium (SP 1) (32-bit)

    Intel Core2Duo T5750 (2 GHz)

    4 GB of RAM

    The problem is that every now and then I hear the optical drive ejection sounds, even if there is no disk in it. It does not seem to occur when a disk is inside... I can play the CD albums without their ejection play environment.

    I don't think that the behavior is a serious problem (the sound of the drive sounds more or less like a normal release mechanism). However, it is quite boring and confusing, and I don't think that it's 'normal' because we have an another Studio 1535 (exactly the same characteristics) that does not behave like that.

    If anyone can help me to correct this behavior, I would be very grateful!

    Thank you

  • Need help to install Windows 8.1 on the partition, bootcamp on Macbook Pro 15 "mid-2010 w / no optical drive"

    I tried for almost a week in all possible ways to get windows installed on a boot camp partition on my main SSD 1 TB drive as a partition, or on my HARD drive, which is installed in place of the optical drive.  So far, everything I tried to give me some sort of error at some point in the process.  It seems that many of them are case by case, so I thought that I invite you all and see if you can help!

    I use a Macbook Pro 15 "mid-2010 that I improved with a 1 TB SSD drive as the startup disk.  My optical drive was not functional, so I moved my old 500 GB HARD drive to the location of the optical Bay.  I am also under the latest version of El Capitan (10.11.6)
    Here are my system specs:


    Presentation of the material:

    Model name: MacBook Pro

    Model identifier: MacBookPro6, 2

    Processor name: Intel Core i7

    Processor speed: 2.8 GHz

    Number of processors: 1

    Total number of cores: 2

    (By heart) L2 Cache: 256 KB

    L3 Cache: 4 MB

    Memory: 8 GB

    Processor speed of interconnection: 4.8 GT/s

    Boot ROM version: MBP61.0057.B11

    Version of the SCM (System): 1.58f17

    What I tried (from what I remember):

    I tried to change the Bootcamp info.plist file for my version of the macbook pro to use a USB stick for the installer.  It seems to have installed correctly but once I partition the disk and restart the computer, it gets stuck on a white screen with the Apple logo and I am forced to make a hard stop and then hold down option to boot into OS X, recovery, or the EFI Boot.

    If I go through the windows installation to start the EFI system, I get an error of:
    "Windows cannot be installed to this disk.  The selected disk is a MBR partition table.  On EFI systems, Windows cannot be installed on GPT disks. »

    I also tried to create a partition by using disk utility, and that too made me an error in the installation of windows.

    So far, the only way that I'm away from windows to run at all has been using the free trial of VMware Fusion 8... but I intend to use windows for more intensive tasks like audio pro, and merger simply does not offer the performance necessary to run these programs.  I'm hoping to install windows 8.1 on my internal SSD or HARD drive, regardless of the work - as long as OS X and files associated with it are left alone.

    If someone could help me please understand this point, I would really appreciate it!

    Thank you

    If your computer has an optical drive, you must use the optical drive to install Windows using Boot Camp Assistant.

  • You can install Windows on a Mac without an optical drive

    Hey, I have a Mac end 2011 a friend gave to me and he said it was broken. I realized that it was just the SATA port on the motherboard, so I pulled out the optical drive and I put an SSD in it. Now I want to install Windows but Mac says that I am not allowed to because I don't have an optical drive. I tried Abu tools and many other shippers of EFI boot, but none of them does not seem to work! Please help me fast! I am computer LITERATE, so no response even if it is complicated would be very useful. THX

  • Question about installing an SSD in my optical drive

    I'm looking for pulling on my optical drive and put in an SSD, because I was told it can do my slow Mac run very fast. My thought was that rather than spend on my existing hard drive, I would take the optical disc and install my SSD it (I've seen a lot of videos shows how to do this)

    My original hard drive offers 500 GB and also have a Windows partition, so I'm a little afraid to play with it, too... Adding an SSD will give me a feature from the application of some of the work for the SSD (such a start and some slower applications) to work only with a specific hard drive? And if I did start Mac on the SSD, should I uninstall and reinstall OS X on this new SSD?

    Sorry, I'm really new to all this. Any help is appreciated!

    My first step would certainly be in lieu of the HD with an SSD. Then assess where you are and what you think of your 'new' machine.

  • Optical drive will not read anything else professional films

    So, I am owner of a 2012 MacBook Pro 13 ". The computer comes with Intel Core i7 processor and has the maximum of 8 GB of Ram. The problem is that the optical drive that is built into the computer will read nothing else done professionally movies. It can read disks of movies like the Lord of the rings and Wargames, to name a few, I tested, but it will not read any DVD-R disc or to a CD. I tried the CDs as Metallica music... And Justice for all after try in another computer and a radio and get good results when it just won't play on my Mac.

    I have had this problem in the past , but at the time the optical drive not read anything at all. This occurred in early December and I fixed it on 20 December. To solve the problem, I went to the Apple Store and they can Reset the P - RAM. The Apple guy he told me to make sure to disable every night. I did this because it's what I did in the past. After that, I was able to play any CD or DVD and burn them. I also tested it every two weeks by playing a DVD in there to check that it still works. But I discovered that it was broken again when tried to insert a DVD-R to burn things on it and the computer only it spun and then ejected it. I've known this current problem since around mid-April.

    I did some research on it and what I have read I believe that I must buy a cleaning disc and run it in my optical drive to clean the lens of the eye out, but I don't understand how I am able to read some disks and not others if that is the problem.

    Can I take it again in the Apple Store and get it looked like or should I buy a cleaning disc and run it through my optical drive, and then decide what to do next? I'm in no hurry to get this problem fixed because my guarantee does not expire until the end of July this year.

    I don't know why you want to put some words in BOLD and a few words in normal font. Frankly I find it a bit annoying when someone does something like that, but oh well... what you could do is to try a cleaning disc (the one with little brushes this topic) or a good breath of air compressed. In addition, some brands of DVD - R Virgin do not work as well as others. I found verbatim to be good, maybe maxell or Taiyo Yuden. Your mileage may vary...

    If this still does not work, feel free to zap the pram x 2-3) and do an smc reset. Shut down the computer, plug power adapter, hold down the left shift, control, option, and button works / stop for about 45 seconds, let go of all of them, then press the power button to restart. If none of this works, then by all means to make a genius bar appointment and bring it in to your local Apple store. Hey, if you have an extended warranty, might as well use it, right?

    Good luck

    Some of the apps in FCS are dead in the water, and others work with features limited or erratic.

    Anecdotal reports of problems running FCS on model are all over the map. Some do work, some don't.
