Ejecting the disc external hard Force required

Hi-

I thought before that I had a solution to this problem, but obviously not.

Almost whenever I click on the icon next to my external hard drive backup disk, in the left pane of a window of Finder, place appears an alert...

The eject button Force works, so I have a workaround, but it seems unfair to have to use it.

Time Machine power down and restart my machine clears the problem for a while, but then it comes back after a few hours or a few days.

I tried to use 'lsof' Unix command in the Terminal, but haven't learned something from him.

Any ideas?

FWIW, I tried to recreate your problem with a USB 3.0 external drive. Unfortunately, I had no problem ejecting the disc without turning off time Machine. It is perhaps a matter of Firewire, but I have no Firewire drive to test.

Something you might try is to reset the SMC or the NVRAM and see if that helps.

  • Cannot eject the disc while running Fusion

    Hi all

    I have an external hard drive with a rarely used vmdk. If I have the mounted external drive, launch the merger and open my Boot Camp virtual machine partition, I can't eject the external hard drive until I stopped the machine virtual Boot Camp and the merger. I think this is new behavior with 2.0.4 and 2.0.5 because I used to be able to eject the external hard drive with Fusion, run the Boot Camp virtual machine. Can anyone confirm this one way or another, and how to escalate this bug/feature of VMware? Thank you.

    Kind regards

    David

    This process works fine on my end.  I have a bunch of virtual machines on my external hard drive and when I insert a boot camp, I'm still able to eject the disc.  You could go to the Help menu merging and choose "Collect Support information" and then attach the file created in your answer.

    Have you added anything as a secondary hard drive in your machine settings virtual boot camp?  Did you add the drive as a shared folder in your virtual machine?  Have you removed the virtual computer in your external hard drive of Fusion and tried it this way?  Have you plugged disk images to your machine virtual boot camp are stored on the external hard drive?

  • Historical files Windows 8 will not recognize the new external hard drive

    I just bought a new laptop (Sony Vaio) with Windows 8Pro (System op 64-bit, Intel I7, 1THD).  One of the reasons is that I have approached Win8, is I liked the concept of the new 'File History' backup utility  I started to use the computer with an ext WD My Guide of the HD and the history of the files seemed to work.  Then the drive external hard went wrong and I just bought a new WD My Passport 2 t ext HD.  Historical files will not recognize this drive.  He keeps asking the old drive.  When I attached the new drive and go to the screen "Select drive", it says "no usable drives are detected.  Please connect a drive... "I know that the drive is there because I see under 'My computer' and I can copy files to it.  But the history of the files do not recognize.  WD, I called and they helped me to update drivers and even made a update firmware on the drive, but nothing is done.  I tried several fixes suggested in a few links Microsoft 'how file history works...

    I was having this same problem, but then noticed a presentation text easy to miss in the historical files tool that says that the disc "cannot be a part of a library" or something like that. In my case, I had files on my external hard drive that have been included in several libraries... and none that I really used, so I removed the files (and deleted the libraries for good measure). A fast system restart later, and my player does not appear.

    I don't know why MS did not propose it again for this thread as the more obvious thing to check, but there you have it. Something simple and quick to check that could save you some frustration.

  • eject the disc from the drive USB Super

    Last night I unboxed my new USB Super drive and attached to my MacBookPro. I put in a DVD of registered film and was able to start playing. Then I ejected it by clicking on the disc icon on the desktop, because I was just testing how it connected etc...  Then, I wanted to see if he could save.

    I inserted a blank DVD and he asked me to tell him what to save, but I didn't save. Instead, he presented another option, which was to IGNORE.

    So I clicked on IGNORE. As a result, there was NO ICON ON THE DESKTOP for this drive. And the text to EJECT in menu bar is grey.

    Now I am sitting here with a new USB Super with a blank CD disk stuck in it and am totally IGNORED, I asked, but what I didn't know when I asked to ignore me.

    That's the problem. I disconnected, signed back in, and he has not yet cleared my instructions to ignore. So I can't eject the blank DVD disc.

    Where should I go from here?

    My MacBookPro is the retina, i7, 15 '' running ElCapitan, a model community 2015, I think.  I'm not on it now, but will open it to follow the suggestions for help. I'm a new converted to Apple, computing, coming from Windows, so I need the regular basic directions. Any help is appreciated.

  • Ejecting the disc will not

    What can I do to eject a CD that will not eject?

    Hello franiebabe,

    ·         What happens when you try to eject the disk by pressing the button of the computer?

    ·         You try to eject the disk by right-clicking on the drive and click on eject?

    If you are unable to eject the disc using the button, you can try to reset your CD/DVD drive.

    Under the eject button, you will find a small hole. Try to stick a needle in the hole. This reset your CD drive and eject it.

    If you still have questions to eject the disc, I suggest you contact the manufacturer of your computer as the hardware may be defective.

  • Cannot eject the disc hard ultrabay in ' Safely Remove Hardware and and eject the media.

    Just installed my T430s with Win7 x 64.
    But I have a problem to the ejection of my hard drive in ultrabay using the icon "Safely Remove Hardware and and eject the media.

    I installed the latest Intel Rapid storage driver (RST) worm. 12.8.10.1005 download of Lenovo.

    UltraBay drive hard not in the list using the driver Lenovo RST!

    If I use the native Win7 driver (Standard AHCI 1.0 Serial ATA Controller), it works:

    Works very well using native driver.

    I guess that the Intel RST pilot could have some improvements to the native driver... so I would frefer using them.

    This is what it looks like in Device Manager:
    Driver Intel RST:

    Win7 x 64 native driver:

    Suggestions... someone at - it a newer driver of RST?
    Tried to find one at Intel without luck :-(

    I tried today with 4 different drivers and here is the result:
    1: "Lenovo" RST driver version 12.8.10.1005: best performance of all. Does NOT support ultrabay ejct!
    2: Intel RST driver ver. 12.9.0.1001: a little slower than 1. Support ultrabay eject!
    3: Intel RST driver ver. 13.1.0.1058: a little bit faster than 2, but not as fast as 1. Support ultrabay eject!

    4: Win7 x 64 native driver AHCI: a little slower than the others. Support ultrabay eject!

    Test drive: Micron C400 256 GB

    Also tried Intel 320 128 GB and using this disc the native driver was also fast drivers Intel RST (did not try the 'Lenovo' RST).

  • Best practices to eliminate the USB external hard drives

    Hello

    I wonder what is the best way to disconnect an external hard drive to USB powered.

    The first thing to do is of course, use the "safely remove hardware and eject Media" next to the clock.

    But, after that do you unplug the power or USB cord first?

    The reason why I ask, is that I noticed the following error in the system event log:
