External HD has stopped working correctly on my iMac

I have 2 external HD aswell as my internal drive that have been running since I got my new iMac under a year ago, however it seems one of my external HD has stopped working so I really need help this drive has important files on I really need to access,
the drive itself lights up when connected and I can hear it trying to work and it even appears in the disk utility however after a few seconds it then disapears from the disk utility and the only wy to repeat this process is to unplug and then plug HD back in via the power cable.
it seems as though my HD is in some sort of sleep mode as the light dims when it disapears from disk utility.
Can anyone plese help?

Off hand I would say the drive may be failing. Contact the original vendor as well as the manufacturer's tech support for assistance.

  • HP Pavilion external monitor has stopped working with my Macbook Pro (Mid 2012) with OSX 10.8.3

    HP Pavilion external monitor has stopped working with my Macbook Pro (Mid 2012) with OSX 10.8.3.  When I purchased the monitor a few weeks ago it worked perfectly when computer was in clamshell mode or with lid open. Now external display has stopped working.  When I turn on display it scans for signal but does not find it and then immediately goes into sleep mode.  I am using a DVI connection with the adapter for the mini display plug.  REALLY FRUSTRATING. Any help would be extremely appreciated. 

    Hi lancekatigbak,
    If you're having issues with the display out on your MacBook Pro, you may want to take a look at the troubleshooting steps in the following article:

  • MESSAGE - itunes has stopped working correctly

    Hi,
    I have recently transferred to a new PC and installed itunes 10.5.
    When opening itunes i receive the error message:
    "itunes has stopped working correctly. Windows will close the program and notify you if a solution is available." Needless to say no solution is received.
    A suggestion in another post on this subject in the Apple Support Communities thought this was related to itunes trying to access the itunes store and failing. Following this solution (which worked for the person who had the problem with his iphone) I:
    disconnected from the internet
    opened itunes
    syncd my ipod touch
    enabled the internet
    closed itunes and re-opened it.
    When NOT connected to the interent all was well and I synd my ipod touch. However on re-connecting to the interent I received the same error massage.  This suggests that the problem is something to do with the program trying to access the internet.
    Has anyone any suggestions as to how I can solve this problem? It may not be relevant but I use AVG Internet Sucurity 2012.
    Thanks, Martin

    Great!!

  • Finding text in a PDF using preview has stopped working (correctly)

    Finding text in a PDF using preview has stopped working (correctly).
    When I search for certain words in a PDF using preview, it correctly finds all the pages in the document with that word.  However, it no longer highlights the word being searched for.  I have looked through the various settings and cannot figure out how to turn this back on.
    Thanks.

    4Shared worked, but having to register to retrieve files from there is a nuisance.
    The problem is that you use special graphic state operators inside text objects which is not allowed:

    Have a look at the PDF specification ISO 32000-1:2008 (e.g. at http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf). Table 51 shows that q, Q, and cm are special graphics state operators, and Figure 9 illustrates that these operators, therefore, are not allowed in text objects, i.e. between BT and ET.

  • My trackpad pinch and close has stopped working correctly on web pages, but ok on email?

    Recently the pinch and close on my trackpad has stopped working correctly when I view websites/pages, it will enlarge only once and will not reduce at all after that. Although It works perfectly well when viewing emails. Does anyone know if this can be solved please, my laptop is still under wareenty but this feels like a software problem maybe..?
    Thanks
    Milosorb

    First look at this Apple support article for possible solutions:
    https://support.apple.com/en-us/HT203171
    If no success, sometimes a very through cleaning of the trackpad will restore functionality.
    Last, open the MBP and examine the battery to see if it has expanded.  It resides under the trackpad and may be interfering with it.  If that is the case, the battery should be replaced.
    Ciao.

  • Itunes has stopped working correctly

    Itunes said I successfully installed it on my laptop(with vista). WHenever I try to open the program however it doesn't open and tells me that a problem caused itunes to stop working correctly(It does not give me an error number).
    Is there a way to fix this? I have already scanned my computer for viruses if that helps narrow it down.

    Try and use Microsoft's Cleanup Utility and then reinstall Quicktime/iTunes:
    http://support.microsoft.com/kb/290301
    Make sure it's a new and fresh download from:
    http://www.apple.com/itunes/download/
    See if any of these help:
    http://docs.info.apple.com/article.html?artnum=302538
    http://docs.info.apple.com/article.html?artnum=302386
    http://docs.info.apple.com/article.html?artnum=302775
    If not mentioned in the articles, make a new user account in Windows and see if iTunes opens. That will tell you if there's something funky in your main account (if the new user works), or if you have a system-wide issue.

  • My MacBook trackpad has stopped working correctly and now my MacBook Pro is beginning to malfunction

    yesterday my MacBook trackpad stopped working, after resetting my mac it began working again but was jumpy. Now a day later when I turn my laptop on the mouse works for a short while (maybe 4 minutes) and then begins to go jumpy again and then my screen moves to the right and my programmes begin to open and close randomly based on my trackpad movements.
    I Have no idea what to do! I've tried installing updates to see if it was that but except for that i'm not that used to a Mac so I don't know! Any help appreciated!

  • Built In iSight camera has stopped working on 27 inch iMac and 27 inch LED.

    The camera's on my 27 inch  i7  imac and 27 inch cinema display all of a sudden just stopped working. I checked in the system profiler, and both show that
    they are connected. When I try video chat in iChat the green light comes on and connects like it's a one way video chat... when I try and switch to the display monitor's iSight the green light switches to the other monitor, but the camera is still black... I tried this with Facetime, Skype, and Photobooth, all nothing... Any insght into this would be great. I'm thinking that it could be an internal hardware problem with the machine... Logic or Motherboard....
    Any info would be helpful
    thank you

    Built-in iSight cameras
    These steps are for iSight cameras that are built into a computer, such as the iMac G5 (iSight) or later, the MacBook, or MacBook Pro.
    See if the issue is application-specific.
    Try another application (iSight works with applications like iChat, PhotoBooth, and iMovie HD 6) to see if the iSight camera exhibits the same behavior in all applications. If it only happens in one application, try reinstalling that application.
    See if the issue is user-specific.
    Test your iSight camera in another user account. If the issue only occurs in one user, the issue would be isolated to user settings.
    Find out if the computer recognizes the iSight
    Check System Profiler (in the Utilities folder, inside the Applications folder). Under the USB header, check to see if the iSight camera is detected.
    Reset SMC or PMU
    Reset your computer's SMC or PMU, and then check System Profiler again. (SMC reset instructions for iMac G5 (iSight), Intel-based iMacs; PMU reset instructions for MacBook and MacBook Pro.)

  • Creation of new JSF has stopped working correctly

    Hi guys,
    I'm rather new to JDeveloper, but i have successfully completed 7 or so tutorials without a problem. But recently i have found a problem which i can't seem to get rid of.
    I create a new Application; lets say a WebCenter Application.
    I right Click the view controller and select "New > JSF > JSF JSP"
    Just hit next a few times and finish, so i have a untitled1.jspx on there with all components enabled. and then drag and drop a PanelPage onto the JSPX page.
    Instead of getting the template up, I get a page with
    -<>ROOT
    <>OUTPUT | Page Directive
    This happens with and ADF component.
    If i repeat the same process with other, older projects i can do this and get the correct template still.. So it's obviously something i have done to the way new projects are created.
    Any ideas what i need to reconfigure?
    Many thanks,

    Thanks a lot for your responses: Showing the log of the visual editor has been a lot of help. I've got the following response:

  • The "find" feature has stopped working correctly

    For the last few weeks when I use "find on this page" it doesn't work properly. Sometimes it will find the first 2 letters and then say that the word can't be found. I have even put in words that I can see on the page and it says that they don't exist. Even after it has located the first 2 letters. It seems like the problem exists usually between the second and third letter of search.
    I am finding this particularly annoying as I am doing internet research and may have a gigantic document that I may only need 1 phrase from and it is making it so that I have to read the entire document. Usually very interesting but REALLY slowing me down.
    Is it possible that I have accidentally changed a setting or something?

    Make sure that "Match case" on the Find bar (Edit > Find or Ctrl+F) doesn't have a check-mark.

  • My iPhone has stopped working correctly with Blurtooth.

    I use the bluetooth to connect to my iCom which connects to my hearing aids. It worked just fine for a month. It no longer "tells" me that a message or mail has arrived. It sometimes doesn't even tell me of an incoming phone call. And now it disconnects without warning.
    Thanks for any ideas . . Steve  (iOS is actually 4.2.8)

    Any thing happen if you try to connect to iTunes?
    One thought - do not charge it and let the current charge fade out - then when you charge it back from scratch it should reboot into some working mode
    Another - if you do not want to wait - bring it to a store

  • For some reason Lightroom 2 has stopped working correctly.

    As of this morning I can't even select all and export files to my laptop any more.
    Prior to this I was having problems with selecting all and adding a label. Even though all pics were highlighted, only the first file updates and I need to individually update the label on each file, even though they are all highlighted. I'm very busy and this is very frustrating - is there an update to correct this?

    That was a problem with exporting to my desktop, not my laptop

  • FlexFileUpload_cb has stopped working correctly...

    ...since we switched to ColdFusion 9. Now, it only uploads one file of a multiple file set instead of going through the entire list and uploading all the files.   We finally got our servers switched over to ColdFusion 9 (yeah, I know "What took so long?).  Is anyone else using this ActionScript program created by Ryan Favro for multi-file uploads?  We've been using it for several years, since it was developed for Flex 2, and it was working fine, until we switched the CF side to CF9 - at least that's the only unifying thread that I can find between our two servers.  The Development side is using FlashBuilder 4, and the Production side is using Flex 3.  Both are using Flash Player 10, but both are now communicating with ColdFusion 9.  It was working on CF8 on the Production side.  We can't go back to CF8 because all of the other applications (other than the one that uses Flex need CF9).  Any perspective would be appreciated.
    Thanks
