External Optical Drive Not Recognized

I've been using a Pioneer DVR111 external firewire drive for the last few months. Until tonight it's performed flawlessly.
I ripped a couple of CDs into iTunes tonight, then when I tried to do another it wouldn't work. The CD wouldn't mount and the drive wasn't recognized by system profiler. I hear the drive spin up when the disc is inserted, but that's about it.
I then tried the disc in the internal drive. Also no response.
So I shut the computer down, unplugged everything and waited a few minutes. I think this is called resetting the PRAM or something like that.
I rebooted from the install disc and rann hardware test. Passed without problem.
I rebooted again and everything seemed fine. Both optical drives were recognized in Profiler.
However, when I inserted a disc in the external drive, it again wasn't recognized. And when I rechecked Profiler, the drive had disappeared. The internal drive, however, seems to have remained okay.
Does anyone have any idea what's going on here? Might this be caused by a faulty external drive, or something else? The external was working fine a couple of hours ago, and I'm a little bit spooked that my internal was acting oddly for a time.
Thanks in advance for the help.

Can you be more specific about "Arch Linux don't recognized it"?
Post the output of lsusb and dmesg.
Do you have an internal optical drive? If not, what's the output of 'cat /proc/sys/dev/cdrom/info'?

External Optical drive not reading? Or is it my programs...

Hi,
I currently just got a macbook pro 2011, 15". Two internal drives (120 GB SSD for OS and Programs, 750 GB HDD for Data) & external USB Optical DVD/RW
The issue I'm having is when I insert a real DVD into the external optical drive (which is the orignal from the macbook pro not store bought) it doesmn't read the DVD. I have installed Quicktime, VLC player and everytime the external just gives me the VIDEO AND AUDIO TS folders.. any suggestions in what I need to do so I can play DVD's from my external?
Thanks a lot...

DVD Player requires a properly recognized DVD player to be present in the optical bay in order to play DVDs. You can use VLC, but you will have to do as you're doing. Another option is to edit the DVD playback framework, but I'm not going to post those instructions. You can use Google & do so at your own risk.

External hard drive not recognized by OS

External FW HD not recognized by Disk Utility and "not available" to Time Machine. Had worked fine until last attempt to B.U. Core Duo, OS10.8.4. Suggestions to make this drive available again?

If the drive has more than one interface (USB, FireWire, Thunderbolt, eSATA), try one of the other interfaces.
Check that the data cable is securely inserted at both ends.
Try a different cable.
If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
If you're connecting it directly, try a different port.
Disconnect all other devices on the bus, or as many as possible.
Test the drive with another Mac. Test another drive with this Mac.
If the drive is bus-powered, but has an AC adapter, connect the adapter.
Boot into Recovery and launch Disk Utility. Is the drive recognized?
Start up in Safe Mode and test.
Reset the NVRAM.
Reset the System Management Controller.
If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive has failed. You may be able to salvage the mechanism by removing it from the enclosure and installing it in another one, or in a drive dock.

External Optical Drive not working with iMac

I have a memorex external drive that I have been using to install Windows 7 with boot camp and have successfully used it on 2 mac-mini's. I am not trying to install Windows 7 boot camp on an iMac that has a broken internal optical drive but the external will not run.
I have tried:
- Startup Utility: Can see the external in there.
- External shows up on desktop with Windows 7
- External shows up in disk utility
- Windows shows up in startup menu with holding down Option.
I see iMac SSD Drive, Recovery HD Drive , Windows CD , EFI Boot cd as options.
If I select Windows it takes me to a black screen that says it doesnt see a boot CD clicking on EFI boot does nothing.
Anyone have any possible solutions into getting this to work?

Mac Minis without built-in Optical drives behave differently than iMacs with built-in drives for boot ability,

This is confusing. If you have the external Optical Drive (Memorex) connected via USB to the iMac and insert a Windows 7+ DVD in it, the Apple Bootmanager will see OSX, Recovery HD, Windows (if already installed on the iMac's internal drive) and possibly Windows and EFI boot from the DVD.
The Windows and EFI Boot will not work if you try to boot the iMac from the external. Test this from the internal Optical drive as well. If your iMac is a UEFI Mac (2013+) it will let you boot from the DVD directly (without Bootcamp).
Bootcamp Assistant will refuse to let you use the external Optical drive, if you try use it to install Windows. BCA only works with internal Optical drives as far as Windows installation is concerned, on Macs that have a built-in optical drive. The exceptions to this rule are 2012 Macs and some 2011 models.

Apple external optical drive not working on macbookpro

I removed my optical drive from my 2011 2.3, macbookpro 13" and added a 2nd hard drive. I have an apple external optical drive(cd/dvd) which I hooked up
via usb and it would not work. I connected the apple external optical drive to my two other mac mini's and it works on both of them. Any reason why the external optical drive would not work on a macbookpro? If anyone has suggestions I would be most greatfull. Thank you in advance.

Internal Optical Drive not recognized after trying to Bootcamp

Around 3 months ago I tried boot camping my Macbook with Windows 7 but it ended up freezing and I had to restart my computer. When the computer had fully restarted I found that a few things had changed. First, I now had a 70 GB partition called BOOTCAMP but it was basically unusable since the Windows 7 OS was never installed in the partition, and second the Optical Drive wasn't recognized by my computer anymore so it won't work at all and the Windows 7 CD is now stuck in there.
I tried a lot of different ways that I found on the internet to try to eject the CD but nothing has worked. It's not really a huge deal since CDs are starting to become the new floppy disks but it would still be nice to have this working again.
Also, here's the original post that I made back in December. It never got any replies and somehow got moved but I was never able to see where it got moved because whenever I clicked "discussion" in "Branched to a new discussion." I would get a page that said this - "Unauthorized. Access to this place or content is restricted. If you think this is a mistake, please contact your administrator or the person who directed you here." I know the whole post is pretty long so I have a TLDR; at the end of it and I pretty much summarized the problem again at the top of this whole post.
Alright so earlier today I decided to Bootcamp my Macbook and install Windows 7 with a 70GB partition. I was using https://help.apple.com/bootcamp/mac/5.0/help/#/bcmp173b3bf2 and http://www.howtogeek.com/186907/how-to-install-windows-on-a-mac-with-boot-camp/ to help guide me through the process. Everything was running smoothly at first...I had a 32GB memory stick that I used to load the support software onto and I had a Windows 7 Ultimate 64-bit DVD in my disk drive.
The first problem I ran into was when Bootcamp wanted to download the files onto the memory stick - it wanted me to format the stick. So I went into Disk Utility, clicked on it, went to erase, then formatted it to the same format it was (because it was already FAT) and then it all worked. After getting the support software onto the memory stick the next step was to partition my disk. After doing a TON of research I finally decided that 70GB would be enough for the OS, a game or two, Sony Vegas Pro, and a few small programs. So I dragged the thing to give the new partition 70 GB and pressed install.
Then, the next problem occurred - a message popped up saying "The USB drive connected to this Mac contains a bootable volume. In order to install Windows 7 from the DVD, the Boot Camp Assistant needs to disable this functionality. No information on the drive will be removed, do you want to continue?" I was hesitant at this point to do anything so I googled it and couldn't find much except this thread - Bootable volume on USB flash drive in boot camp. I decided to try it and press continue since according to the thread it would stop me if there was a problem. Once I did I THINK (I can't remember that it did for sure or not) it dismounted the memory stick, which I remember thinking was okay because I could just unplug it and plug it back in after Windows 7 was installed to install the support software (Also, I NEVER removed the memory stick until after a reboot later on). After that Bootcamp began partitioning my hard drive.
About an hour later the blue progress bar had actually filled up to at least 99% (but it looked like 100% to me) but Bootcamp still said "Status: Partitioning Disk" so I left it alone for another 1-2 hours. After that I started getting worried and googled how long this process was supposed to take and found out that this step normally only took a few minutes for most people. At this point I started looking up fixes for this but nothing matched my problem since Bootcamp itself wasn't actually frozen (when I clicked and held on the icon it didn't say "Application not responding") so I decided to check to see if the partition had worked. Then, Disk Utility froze like a few seconds after opening it up so I had to force quit that. My next option was to check under "Storage" in "About this mac" so I tried that and it froze as well. While all this was going on I kept checking back to Bootcamp and it never froze.
Now I was getting extremely worried and with no solutions on Google and no idea what to do I decided to just try and restart my computer and pray to god that it would reboot fine. Luckily, it did...for the most part. After rebooting all my applications seemed to be working fine (I can confirm that Terminal, Disk Utility, System Preferences, System Information, and Safari are all working or at least loading). I also had all my files still on my computer so that was good. Next, I checked Disk Utility to see if the partition had actually worked and it did, or at least it is showing up as "BOOTCAMP" under my main hard drive. Then, I tried using Bootcamp again and this is when I noticed something new - a warning on Bootcamp's first page that wasn't there before, "You need an optical drive to install Windows. Connect an optical drive to your computer. You cannot install Windows with a remote optical drive." I can't guarantee that it wasn't there the first time but I really don't remember it there. After reading that I checked my Desktop for the mounted Windows 7 Ultimate 64-bit DVD and it wasn't there. Then, I checked Disk Utility and it wasn't showing up there either. The only things I can see on Disk Utility are my main hard drive with both partitions, my memory stick, and a random dmg file called decryptedFile.dmg (the size of this file is only 15.6mb so I don't think it could be the OS DVD).
So now I am trying to figure out how to get my computer to recognize that it does have an internal optical drive and that there is a DVD inside of it. I looked around on Google to try to find answers but all the regular options to fix this don't work since the computer itself is not realizing it's there. I don't know if this helps to prove that it doesn't realize this but I checked in System Information -> Hardware -> Disk Burning and it says "No disk burning device was found. If the device is external, make sure it's connected and turned on." And since a "Superdrive" can read disks I'm assuming it can burn them to and would be shown under that. (I don't know that much about computers though so I could easily be wrong)
Anyways, sorry for the extreme detail that I went into but I wanted to get as much information about what happened as I possibly could. For those of you who don't have time to read all that I'll put a little summary.
TLDR; Basically, I tried to Bootcamp my Macbook to run Windows 7 Ultimate 64-bit. I ran into a few problems and then Bootcamp wouldn't move on from "Status: Partitioning Disk" so I had to restart my computer. After the restart my Macbook doesn't recognize that it has an internal Superdrive and therefore doesn't realize that there's a Windows 7 Ultimate DVD disk in it. I looked around for answers but none of the simple ones (using key commands on the keyboard and typing something into terminal) worked. Now I'm looking for help to get my computer to realize that it does have a Superdrive inside so I can get the disk out.
Thanks in advanced! If any more information is required to help please let me know so I can find it. Also, this is a Mid-2010 White Unibody Macbook.

Hello Michael Dixon2,
Thanks for using Apple Support Communities.
In order to troubleshoot this issue where the optical drive does not accept discs, please follow the steps below.
Doesn't accept discs
Be sure to check your disc to make sure it is flat. You can check this by putting the disc upside-down on a flat surface. If the disc is bowed up on any side or in the center, do not use the disc because it might get stuck in the drive. Do not use discs that have anything attached to them or dangling from them (such as "sweeper" or cleaning discs).
If the drive struggles when you put in a disc or stops part-way, carefully look at the disc for labels that may be interfering. If there aren't any raised labels then try putting the disc in a few more times.
Try another disc to see if the issue is being caused by a specific disc.
Make sure you insert the disc far enough for the drive mechanism to activate. You need to insert discs nearly all the way before the drive will activate and pull them in. If you don't completely insert a disc, the drive will reverse and push the disc back out.
Allow the drive one or two seconds to accept the disc while it is fully inserted.
Reset the System Management Controller (SMC).
If the drive repeatedly does not accept discs, contact Apple or an Apple Authorized Service Provider, or make an appointment with an Apple Retail Store.

USB external Super Drive not recognized by iMac

Bought a new USB external Super Drive a few days ago (from Apple shop).
Plugged into my iMac 21.5", late 2013, and the iMac does not seem to want to recognise it.
Checked Finder and necessary boxes ticked up to show on Desktop, also does not show through remote devices.
Any help would be appreciated. Not a techie and 90 miles from my Apple shop.Not even sure I have filled the dam request in correctly (sorry).

Oddjob, the optical drive itself never shows up on the desktop,. What happens when you insert a disc? If a disc doesn't show up first check your connection. Try resetting the SMC Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support and PRAM How to Reset NVRAM on your Mac - Apple Support
There's also the possibility that the drive is bad.

External Hard Drive not recognized.

Hello everyone,
I have a probem where my external hard drive is not being recognized by my late 2009 iMac.
The hard drive is an OWC Mercury Elite-AL Pro connected to the firewire port.
It was working fine till this happenend:
I keep all of my iTuned music on the external hard drive.
I was using a meta tag fixer type program.
I dragged the files from itunes into this program (Tune Up) to fix the meta tags.
However, I missed the program and dragged thusands of .mp3 files onto my desktop.
My computer, of course, became unresponsive.
So I used the power button on the back of the iMac to shut it off.
I used my MacBookPro to connect to my iMac as a target drive, and deleted all the .mp3's from the desktop there.
Once I restarted my iMac everything was fine, except that the external hard drive has not been able to be recognised ever since.
The same drive shows up just fine on my MacBookPro.
Help!
Thanks!

I had the exact same problem! I had to force shut down my iMac (24in, Mid 2007) due to a system freeze. After restarting, everything was working fine, except for my external 1GB G-Drive, which was connected through FW800 port.
The drive connected fine to my MacBook Pro, but it would not be recognized by my iMac. I tried restarting, but neither Disk Utility, nor System profiler would see the drive.
What worked though, was Resetting the System Management Controller (SMC):
1.          Shut down the computer.
2.          Unplug the computer's power cord.
3.          Wait fifteen seconds.
4.          Attach the computer's power cord.
5.          Wait five seconds, then press the power button to turn on the computer.
The drive mounts fine now. I am surprised this is not mentioned by Apple in their support documents! It has happened twice to me and it was the only thing worked both times. The link for the resetting the SMC is here:

Hope this helps solve your problem too.

Toshiba StorE Art 2Tb External Hard Drive not recognized by HP Elite /Win7

I have a new HP Elite Desktop running Windows 7 Home Edition:
I bought some few months ago a Toshiba Store Art 2Tb Ext Hard drive, which until today worked well. Today I started the PC in the morning (with no update of Windows or other software) to find it would no longer recognize the Toshiba Hard drive. It still recognizes the WD drives, and the SimpleTech drives when they are plugged in. All External Drives are powered separately and do not rely on USB power.
I tried the Store Art on other PC's and it works fine. I tried switching the cables, and the cable works on other drives, (and other cables will not make this Store Art work). I tried several USB 2 ports on the PC, with no luck *(but all ports work with the other drives).
I tries COMPUTER, MANAGE, and checked Drvivers and Disks. There was no sign of the Disk available (no malfunctioning disk), it was just not there at all.
I searched the web - tried a range of techniques (unplugging PC from power) and more. No luck.
The PC Specifications are:
Operating System
MS Windows 7 Home Premium 32-bit SP1
CPU
Intel Core i3 530 @ 2.93GHz 30 C
Clarkdale 32nm Technology
RAM
3.00 GB Dual-Channel DDR3 @ 665MHz (9-9-9-24)

Optical Drives
WD Virtual CD 1110 USB Device
hp DVD-RAM GH60L
Audio

Works well with all other drives. and it worked with Toshiba till this morning.
Any clues?
thanks

Well - this is incredible. After leaving the Ext Store Art Drive turned off all day ( but the PC was left on) | cam home ready to try the advice of Keaney (thanks for your advice) which was the same as the techies at work: Try to roll back to OS to last good restore point - eg a week ago. Just before I did anything like that - I just flipped it on to see if a miracle occurred. Guess what. It fired up, was recognised, and all is working.
This is amazing - since my original posting: the PC has not been restarted, not been turned off, not been updated with new OS updates, has not had anything except normal web usage. Similarly the Store Art Ext HDD has been left off for the day, and just turned on tonight - not change plugs or cables or USB or anything. No cables have been touched or plugs jiggled. It just works.
Its like there is a gremlin there - teasing me, testing me, causing me havoc - and laughing all the way. I have no idea how this happened - but will monitor to see if it happens again.
thanks for the suggestions to resolve - for now I will do nothing.

Some data DVD's and External Hard Drives not recognized by Leopard only.

1] Some data DVDs that were burned under Tiger do not show up in Leopard. Only a dialog box asking what I want to do with the blank DVD comes up when I insert the disk. On my Tiger computer, the disk shows up perfectly fine. It is a DVD+R being used on a MBP 2ghz... and was burned on that very machine in Tiger and would load fine in Tiger. Now nothing on the same computer in Leopard. I'm going to reburn the disk on my Mac Mini on a DVD-R, but still wanted to know any ideas or input as to why it won't recognize the disk.
2] I also have an external USB2.0 HD. I formatted the disk using my G4 Mac Mini (which has Tiger) and it is not recognized on my MBP. In Disk Utility I try to reformat the drive, but it says that it cannot do so because the "resource is busy". I plug the drive back into the mac mini and it works perfectly fine. Why would this be and how do I correct it?
Full updates on both OS's. No other problems with either computer that I know of.

Unfortunately, commercial DVDs that you have bought 99.9% of the time will be copy protected and Apple's forum terms prohibit discussion of circumventing the copy protection. In various places circumventing digital copy protection is potentially illegal even if you own and intend to keep the DVD. Hence Apple do not wish DVD rippers etc discussed here.
Another problem is that AppleTv cannot play back DVDs copied to an external drive as it does not understand the format. So even if you can 'copy' your DVDs you then need to convert to h264 format to play on AppleTV.
Video formats for AppleTv are limited. They also do not support DVD like menu structures (thogh AppleTV 1 did with itunes Extras movies).
If you have unprotected video you wish to convert eg home video on DVD, then something like Handbrake or MPEGStreamclip with Apple's MPEG2 component might do the job. These programs are not DVD rippers but can process unprotected MPEG2 video.

External DVD Drive Not Recognized

Just got a Toshiba portable supermulti DVD/CD drive. My internal drive is fried and figured it would be cheaper to get an external until I can get a new computer. Except, when I plug it into either of my USB ports, the drive lights up and makes noise for about 10 secs, then stops and it does not register on my computer. The drive shows up on the System Profiler, but nowhere else is it recognized. When I try to open Disk Utility, it just says 'Gathering Disk Info' and just pinwheels and is Not Responding until I Force Quit. Any thoughts as to what the issue is? My computer recognizes my external hard drive, iPod and anything else I plug into it and the DVD drive was recognized no-problem by my Dad's new Macook Pro and by my brother's PC. I should say I have the 2007 model Pro. Thanks!

Is the DVD drive externally powered? I.e. does it have a power supply?
For exmple my LG external DVD won't work with a single USB on my Macbook Pro - it requires another usb cable that has a power plug on the end. So both USB ports are used.
It kinda works without power, but it's unreliable, it could be you're having a similar issue?

External hard drive not recognized... help please.

okay, well here is the story:
my iBook G4 had its stock 30gb hard drive in it and it was running extremely low on space. so i figured i didn't want to carry around an external hard drive, therefore i would buy an internal hard drive an install it. so i purchased a new 2.5" 80gb hard drive and called up the local apple store. they told me that although it was under warranty, that it did not cover hard drive installation. so i looked it up online and found step by step instructions to install the hard drive. so after lots of hard work and many screws, i installed the new hard drive successfully... but i still had this perfect 30gb hard drive. i thought maybe to save a few bucks i could turn it into a usb external hard drive. i found an enclosure for the hard drive and a usb 2.0 cable and plugged it into my ibook. it was recognized and everything. i put some files on the external hard drive and transferred it to another mac. this is where the trouble started. i plugged the hard drive into a PowerMac G4, and it was not recognized... so i tried it on a different mac. this time on a PowerBook G4, but no luck. this issue has been troubling me for a few weeks. but then i tried it on a similar iBook G4... and it was recognized. but i don't know why it was only recognized only on the iBook G4 (not the same iBook G4 it was pulled out of) and no other macs.
does anybody have any ideas what we can do to get this hard drive to be recognized by other macs?
any of even the smallest ideas would be greatly appreciated.
thanks,
tyler
iBook G4 Mac OS X (10.4.3)

I can walk you through formatting the hard drive:
1. Hook it up to an iBook that recognizes it.
2. Go into your Applications folder, then scroll down to Utilities. Open Utilities and scroll down a bit and you should see Disk Utility. Double-click.
3. On the left side you should see your internal hard drive and your external one. Each hard drive will have a sub-catagory with the partition indented.
4. Your external hard drive will probably be the second catagory. Click it.
5. In the center-top you should see the tabs First Aid, Erase, Partition, RAID, and Restore. Click the Erase tab.
6. You should see Volume Format: and then a drop down menu, and Name: and a text box. Type in the name you want the external hard drive to be named.
7. In the drop down menu, select Mac OS Extended (Journaled).
8. Then, simply click Erase, watch the progress and it should be good to go!!
Hope I helped you out. Oh, and it might be the enclosure...and also what OS's? Since it's USB it is probably using a USB Mass Storage driver. Mac-wise, if formatting doesn't help, I would get a FireWire enclosure because FireWire is much faster than just USB 2.0. Oh, thats nother thing...Is the enclosure Hi-Speed USB? If it isn't, I would definitely get a FireWire one...If it is, the PowerMac G4 doesn't have Hi-Speed so you're not taking full advantage..Just some insight

External hard drive not recognized by LR 3.6

I'm running Mac OS 10.8.2.
One of my external image storage drives is not being recognized by LR 3.6. The drive shows up on my desktop and can easily be accessed by other apps. But it's not included in the list of drives in my Folders. All other external drives show up fine.
Interestingly, if I boot up with my back-up external boot drive, it shows up! The back-up and the regular boot-up are identical in every way.

Ok ... here are the screen shots. I hope the details are visible.
• First screen shot shows LR Library when started from main drive. Drive is called "10.6.8 #3" Selection in Library is on "Previous Import," which is all of the images I re-imported last night to drive 10.6.8#3. All images show up and are accessible for all functions, ie Develop, etc.
• Second screen shot is the Import Source folder from the same start-up. All connected drives show up.
• Third screen shot shows LR Library when started from back-up boot-up disk, which has the same content as 10.6.8#3. Back-up is called "10.8.2#1." Library selection is on "Previous Import." As you can see, all of the images are grayed out and have a question mark. The connected drive, 10.6.8#3, doesn't show up in the Folders list.
• Fourth screen shot is the Import Source folder from the back-up boot disk. 10.6.8#3 shows up.

Slot loading optical drive not recognized.

Recently I replaced a none functioning optical drive in my 15" 1.67 HS PB with 2.0g ram 160hdd. On reboot it will show a grey screen or a ? folder. I have tried everything ( and I mean everything) 2x over. This is what I find:
1) The PB will boot up fine if only either the od or the hdd is connected to the mother board. But not with both drive connected.
2) The PB will boot up with an external PB2 in target disk mode with only the od drive connected. I mentioned this because this allow me to use apple HW test that described the hdd as ID-0.
3) The od is a UJ85J-B panasonic/masushita from owc. Exchanged x2 thinking its defective.
I believe this is a master/slave issue. my question is will the following article apply to my situation.
http://www.xlr8yourmac.com/tips/PioneerK04L_mastermod.html
Is ther anything else I can do or use the od as an external?
Will very much appreciate any in put.

We have 3 right now having problems. 1 just went into the ITech store to have a CD removed. 1 will not even accept a CD anymore and the other just makes awful noises and scratches the CD. These have been minimally used also. They said the Optical Drive is bad on the 1st one. Of course, we are 1 month past our warranty! I think Apple should be backing this but when I called about it they didn't want to help me. Even saying I had not registered them even though I had documentation from them saying I had. I know the feeling of being ripped off. Our company has purchased 20 of these in the last 1 1/2 years. You think we would get a little bit of help from Apple being we have purchased so many of their products in the last 20 years.
