Air/Retina Mac's Won't Mount External Optical Drives

Please Help.  I recently upgraded hardware from a 2009 MBP and a 2007 MBP.  My current problem is that on the i7 Air and i7 MBP w/ Retina it will no longer recognize USB Optical Drives on 10.8.2.  It was crashing my i7 Air (panic attack-grey screens), so I returned and went with the Pro after store consult.  I take the same hardware and plug it into my old machines and it works fine, running the same 10.8.2. 
I have read many forum posts around the net and shown various solutions (flashing RAM, etc.).  All of which have not worked on my setup, and the drive will still not mount.  I have tried 2 seperate optical drives, 1 Blu-Ray and 1 DVD (Apple Superdrive - now returned). 
Is there some tie to this issue and the fact that both the Air and MBP w/ Retina do not natively have optical drives?  If so, is there some solution that can be performed to properly address this issue.  This is a reasonable use case and I do not want the models with optical drives.  Kinda surprised considering that Apple is pushing us to this no optical drive world that they would not support external ones inclduding their superdrive, which doesn't work in this case.

  • Mac Mini won't read external hard drive

    Hello, I have an external Toshiba hard drive and my Mac Mini will not read it.  It was originally used on Windows.  I plugged the hard drive into my Macbook and it worked as a read-only device.  I can take stuff off of it but can not write stuff onto it on my Macbook.  I want to use it so I can back up files on my Mac Mini, but it will not read it.  I know I have to format it to make it writable with Mac, but I want to make it a read only device on my Mac Mini because I want to back up all the data already on it and my Mac Mini has 400gb of its hard drive available.  How can I get my Mac Mini to read the Hard Drive? 

    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 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.

  • Suddenly Mac mini won't "see" external drives. Possible related to OS software update to 10.6.8?

    Suddenly Mac mini won't "see" external drives, neither Firewire nor USB. Possible related to OS software update to 10.6.8? Worked fine under 10.6.4. Any advice? Thanks.

    Turns out it was nothing to do with the OS update, it was just a loose cable plug connecting my FireWire/USB hub to the computer. But your tip is a good one -- I'd been wondering why the external drives (even when mounted properly) weren't showing up in the sidebar. Thanks!

  • What do i do when external optical drive doesn't show up in finder?  how can i import software, music, etc. when the drive isn't recognized/mounted/whatever?

    the internal optical drive on my early 2006 20"imac has mechanical problems ejecting discs.  i've gone thru all the recommended steps to eject discs, and have luckily been able to eject the last 3 discs but only after spending 30-60 minutes going thru all of the steps over and over, and today just trying "eject disc" in itunes since i had itunes open.  i don't want to put another disc in - the drive clearly has problems with the mechanical eject mechanism, and from what i've read that's not unique to my computer.
    i bought an external optical drive: lite on, clamshell design to avoid problems with the eject mechanism; i contacted the mfr who said it's mac compatible.
    the drive plays dvds, which is all i've tried so far, but doesn't show up in finder.  so i don't know how to use it to load software, or music, or anything besides watch dvds.
    is there something i can do to get the drive recognized/mounted/whatever?  i would prefer to not spend the $220 which was quoted to me by an authorized mac repair company, even tho i think that's probably a reasonable cost given the delicacy of the operation as shown on ifixit.com. 
    thanks!

    I have an external LaCie burner and it will not show up on my Mac unless I insert a CD or DVD - in that case, the media will show up (I have these settings in the Pref Pane):
    If you want to burn files or music to blank media, you can use Finder or Disk Utility for files, but should use an iTunes playlist/iTunes for music and a movie burn app for videos/movies (such as iDVD, Roxio Toast, Burn, etc).
    If you simply want to drag files over as a backup, an external hard drive is a much better solution than a burner.

  • External optical drive won't play movie DVD

    The SuperDrive on my very late 2009 MacBook (OS 10.5.8, Leopard) died, and I got a well-rated CD/DVD player/writer, Samsung SE-218BB) instead. It is meant to be compatible with my Mac. It works with things like Disk Warrior, but recently, I tried to play a video disk and got the message "Utilization error. A valid DVD player could not be found (-70012)." I've read a lot of other messages about this same error and have done what was recommended (throwing out the appropriate plist file from DVD player, for example). The messages were for other Mac models and/or versions of OS X, so maybe there is some advice that is specific to my Mac that would pertain? By the way, the DVD does show up in the Finder in a generic kind of way (that is, I think it is the kind/manufacturer of the disk,but it certainly isn't the name of what is on it), and when I click on that, it opens a bunch of separate files that don't seem to have much to do with watching the movie.
    I also tried one of the tips given in the DVD Player manual (dragging the file to the DVD Player icon. All that did was make the DVD disappear. I had to restart,, with the mouse "button" (really not a button) on the Mac pressed, which released the DVD from the external drive.
    I don't think the problem's with the hardware, since I can play Disk Warrior in it (that opens automatically after I insert the DVD. So what's with the movies? I've checked Software Update, and my software (DVD Player 7.7) is up to date for my Mac and OS version. I don't even know whether I should be using DVD Player for movies. (I haven't tried a music DVD, but I suspect that should open in some other app.) I don't remember playing movies on my computer when the internal SuperDrive was still working, so I can't make that comparison.
    I hope you can help me. I'd be very sorry if I had to give up on playing the DVDs I now have. My VHS/DVD player-recorder used to be just fine, but my cable company set it back up wrong when they installed a new cable box, and now they want $50 even to look at it, so for now (until I find some company, say, the manufacturer of the player, that can tell me how to set it back up) the only way I can play and burn movies is with my computer.
    Thanks,
    jenny

    I have discovered, no thanks to Samsung techs, what the problem is, and it might be revealing for others, as well. It seems that DVD Player, which is the app Apple provides in OS x for (naturally) playing videos, doesn't work with external drives if the computer has an internal drive – even when, as in my case, the internal drive is dead.
    I have learned, however, of the existence of a couple of alternative, free applications that run video and audio disks with external optical drives, and one of them, at least (VLC), seems to be widely acclaimed. Does anyone know whether bypassing DVD Player could be a bad idea? There were some gripes from one or two reviewers about awkwardness with playing audio DVDs with iTunes, but I'm not sure what they meant when they said that you have to click on individual items in a selection. Would that mean, for example, having to click on each movement of a Mozart trio? That I couldn't play an entire album's contents of another kind of music without clicking on each song?
    Getting the internal optical drive replaced would be prohibitive, even if the parts could be obtained, so I guess I'm stuck trying to deal with the external drive I have and finding the best replacement for DVD Player that I can find. The interesting thing is that the drive works beautifully with a MacBook Air I tried it with, so I guess that is because the Air doesn't have an internal drive?
    Wouldn't you think that Samsung techs would know all this? The one I spoke to told me to make sure that my system preference for CDs and DVDs was set to open automatically with DVD Player and sent me all kinds of FAQs, plus a way to get an RMA number for a return. Not a word about difficulties with Macs having an existing internal drive. And all after spending a very long time talking with me about what was going on, what the error message was, and so on. I guess the message hasn't gotten to them.
    I hope this information will be helpful to someone.

  • Mac mini and External Optical drives

    hi all,
    just wondering if i'll be able to use external optical drives with my mac mini which doesn't have a DVD writer, it detects and mounts in OSX, but can't playback a dvd or burn, do i have to use any third party software like roxio?
    any help would be much appreciated.

    You omit specifics but this might help, especially if you already have an external hd on firewire and plan to add an ext optical drive to the firewire chain. Burn Disk created one perfect DVD (consisting of backup files) but then became flaky, dying during burns. Patchburn (www.patchburn.de) did not help this problem but it did change system profile of the new optical drive from: 'unsupported' to 'vendor authorized' which may have helped generally. With Panther it will be required!
    I did lots of searching on Web, Groups & Apple Discussions but could not find anything on "Error: 0x80020020: BE, sense error, etc".
    I discovered the solution to this problem: I put the DVD external drive between the Mac Mini & the external harddrive (instead of at the end) and now BurnDisk works 100%. "Sense Errors" were common back when I was using SCSI drives and usually pointed to cable length issues. This was the simplest alteration I could make to my PPC G4 Mac Mini setup. I am using the 3 ft shielded cables that came with both of my external enclosures so it is reasurring that these did not have to be modified.
    Now Burn Disc creates solid DVDs of backup folders, no more coasters or long pauses in the burning process, followed by the inevitable error code.
    Using Pioneer DVR-112D drive in a generic ext enclosure. The drive is current production so I have not modified the firmware. Using Memorex DVD-R from WalMart.

  • Mac newbie cannot access Mac Mini's Iomega 200gb external firwire drive

    After a power problem - I powered on my Mac Mini to find no external firwire drive
    I have my data backed up - so I reinstalled OSX
    I am now at the stage where Disk Utility
    can see the disk,
    I ran disk repair - it said all ok
    but no icon on desktop (I am logged in as Admin)
    I plugged in my work usb disk its icon appears ok
    the firewire reports its mount point: /Volumes/Iomega HDD
    when I safari that it returns "you dont have permission"
    but when I safari my usb drive I get to see its contents
    it looks like I (admin) dont have permission on the disk - and "repair disk permissions" is not clickable
    Its a step forward but I'm stumped - on the plus side I am learning OSX's quirks having been a micro$oft user for so long and was pleasantly surprised with os reinstall ease.
    also finder finds all my stuff (but its in ghost font - unclickable ! )
    is there some utility to force admin permission?
    or am I thinking about this the wrong way?
    I also am not too worried about reformatting the disk, as I have 99.9% of the data backed up (the only thing I thank my years of Micro$oft use for lol)
    however a part of me thinks a reformat will give me a blank disk - with no permission
    help!

    Do you have access to another Mac? It would be helpful to try the external drive with another computer to make sure the problem isn't with your Mini (it probably isn't, just good to eliminate that as a variable). I don't know Dublin, but surely there's a Mac retailer somewhere that has a few demo machines out.
    Alternately, you can create a new admin user on your Mini, log into that user, and try accessing the drive there. This would show you if it's a problem with your main account or specifically permissions.
    You should also check your Finder prefs and make sure you have removable drives set to show up on the Desktop. Since you just did a clean install and this is the default (I think), this shouldn't be a problem, but it's worth checking.
    If none of these steps yielded positive results, the next thing I would do is run Disk Warrior. This is arguably the best disk repair app for Mac OS X; it's definitely my favorite. Your external drive could have a corrupted directory or some other problems that Disk Utility isn't seeing/fixing for whatever reason.
    If none of this works, reformatting the disk is the last step. As long as the drive itself isn't physically damaged, and the problem isn't something on the Mini itself, reformatting should fix the problem completely. And since it sounds like you have your data backed up, maybe you should just skip to this step and be done with it.
    Good luck.

  • New MAC Mini w/OSX Lion - will not boot from USB or external optical drive when attempting to use BootCamp to install Windows 7?

    The University recently purchased 6 brand new MAC minis for deployment in classrooms I support.  I am attempting to create a dualk--boot environment comparable to our existing computer systems, only these machines wil be running MAC OS X Lion and Windows 7.  After following the procedures outlined in the BootCamp on-screen prompts, and attempting a few techniques I found in the tech support user-base, I am still unable to get the MAC mini to boot up from the USB flash drive, or from an external optical drive, so that I can complete the installation of Windows 7.  When using the Boot option key at start-up, all devices are displayed suggesting that they are being properly recognized, however the computer boots to a black screen with an error message indicating that "No bootable devices are  found - press any key to continue." I am able to boot into the computer's internal drive, but not from any external devices.  I fully expected that the semi-automated BootCamp procedure properly prepares the USB device for booting, and for installing the Windows 7 OS.

    Meh, with the price they take for a drive in Denmark, I don't think it's worth it... They take around 160 $ for the drive (that's the cheapest MacBook drive I could find), and I am not even sure that's the one I need.

  • Installing Win7 on a macbook pro using a mac mini as external optical drive

    hi everyone,
    My 2 year old son watches movies on my macbook pro. He stuck something in the optical drive making it unusable. Repairing it is 200 to 300 euros (ouch).
    I want to install win7 via bootcamp and I'm using my mac mini (october 2009) as an external optical drive. These are my steps:
    1.hold the "t" on the mac mini
    2.connect it to the macbook with a firewire 800 to firewire 400 cable
    3.Power up and hold the "alt" on the macbook
    4.I see the optical drive on the boot screen and I choose it
    5.Then I get a blank screen and a few seconds later the "missing operating system" message appears.
    Am I missing something? Is it possible to install win7 using a mac mini as an external drive?
    PS1:I already have partitioned the HD with bootcamp.
    PS2:I've upgraded the hard disk drive of the macbook with a seagate momentus 500GB hard disk. Don't think this is the problem, thought I should mentioned it.

    Hi Mike,
    For reference it is called "IP over Firewire".
    Connect the two computers with a fire wire cable. System Preferences > Network > Configure IPv4: > Manually > IP address: 192.168.3.1 (and .2 on other) > Subnet Mask: 255.255.255.0. Leave the other fields blank. Do this on both computers on the computer you want to allow access to or both for two way access go to System Preference > Sharing > Select a service to change its settings. Turn remote Login on.
    On the MBP go to the Finder Menu > Go > Connect to Server > Type in the IP address of the Mini 192.168.3.2 (Whatever you gave it)
    With this configuration you still have full use of the Mini and certain apps can use Xgrid and use the processor of the mini when it is not doing anything. I would keep the Mini as 10.4 unless you really need both machines running Leopard. As noted before you cannot boot the MBP from a HDD that is Apple Partition Scheme and vice versa you cannot boot the PPC from a Guide Partition Table.

    Hello, I have two questions on time capsule  I can only have it on my external hd files and free up my internal memory to my mac  I can use an external hard drive, in my case a lacie rugged as shared memory for my two computers

    I have a mackbook pro and an iMac if I buy a time capsule 2tb airport, I can use it with time machine and what would be the best way to use it.
    There is no particular setup required for TM.. both computers will create their own backup sparsebundle which is like a virtual disk.. Pondini explains the whole thing if you read the reference I gave you.
    and how to use time capsule airport whit other external hd to use my old lacie airport with the new time capsule
    Up to you.. you can plug the external drive into the TC and enjoy really slow file transfers or you can plug it into your computer and use it as external drive.. which is faster than the TC.. and TM can include it in the backup.
    Again everything is explained in the reference.. you are not reading it.
